MCQmedium

A company runs a combination of Amazon EC2 instances and AWS Lambda functions for its applications. The finance team wants to reduce costs by making a commitment to a consistent amount of compute usage (measured in dollars per hour) for a 1-year term. The team wants the flexibility to change instance families, sizes, and AWS regions, and also wants the commitment to cover both EC2 and Lambda usage. Which AWS pricing option should the team purchase?

A.Compute Savings Plans
B.EC2 Instance Savings Plans
C.Reserved Instances
D.Spot Instances
AnswerA

Compute Savings Plans offer the broadest flexibility among AWS savings plans, applying automatically to EC2, Lambda, and Fargate usage across any instance family, region, or operating system. This makes them the ideal choice for a team running a heterogeneous mix of EC2 instances and serverless workloads, as the same hourly commitment covers all compute usage. By committing to a consistent dollar amount per hour (typically 1 or 3 years), the team achieves significant discounts without being locked to a specific instance type or size.

Why this answer

Compute Savings Plans provide the required flexibility to change instance families, sizes, and AWS regions, and they automatically apply to both EC2 and Lambda usage. This plan offers a discounted hourly rate in exchange for a 1-year commitment to a consistent amount of compute spend (measured in dollars per hour), making it the only option that meets all the stated requirements.

Exam trap

The trap here is that candidates often confuse Compute Savings Plans with EC2 Instance Savings Plans, mistakenly thinking the latter offers the same flexibility, but EC2 Instance Savings Plans are restricted to a single instance family and do not cover Lambda or Fargate.

Why the other options are wrong

B

EC2 Instance Savings Plans apply only to EC2 instance usage, not to Lambda functions, and they require commitment to a specific instance family in a region, lacking the flexibility to change instance families, sizes, or regions.

C

Reserved Instances require a commitment to a specific instance family and region, and they do not cover Lambda usage. The question demands flexibility across instance families, sizes, regions, and coverage of both EC2 and Lambda.

D

Spot Instances are not a pricing commitment option; they are spare compute capacity offered at variable discounts with potential interruptions, and they cannot cover Lambda usage or provide a consistent dollar-per-hour commitment.

77
MCQhard

Which AWS pricing model allows customers to commit to a consistent amount of compute usage (measured in $/hour) for a 1 or 3-year term in exchange for significant discounts, without being locked to specific instance types?

A.Standard Reserved Instances
B.Spot Instances
C.Compute Savings Plans
D.Convertible Reserved Instances
AnswerC

Compute Savings Plans offer flexible discounts across any EC2 instance in exchange for a consistent $/hour commitment.

Why this answer

Compute Savings Plans offer the flexibility to commit to a consistent amount of compute usage (measured in $/hour) for a 1- or 3-year term, providing significant discounts (up to 66%) without requiring you to lock into specific instance types, families, or regions. This model automatically applies the discount to any EC2 instance, Fargate, or Lambda usage within the committed compute commitment, making it the correct answer.

Exam trap

The trap here is that candidates often confuse Compute Savings Plans with Reserved Instances, assuming that any long-term commitment must lock you to a specific instance type, but Compute Savings Plans specifically decouple the commitment from instance type details.

How to eliminate wrong answers

Option A is wrong because Standard Reserved Instances require you to commit to a specific instance family (e.g., m5.large) in a specific region, locking you into that exact configuration, which contradicts the question's requirement of not being locked to specific instance types. Option B is wrong because Spot Instances use spare EC2 capacity and offer discounts but do not involve a 1- or 3-year commitment; they can be terminated by AWS at any time with a 2-minute warning, making them unsuitable for a consistent, long-term commitment. Option D is wrong because Convertible Reserved Instances, while offering flexibility to change instance families, still require you to commit to a specific instance type at the time of purchase and only allow changes via exchange, not the free-form usage flexibility of Compute Savings Plans.

MCQmedium

A company operates three separate AWS accounts, one for production, one for development, and one for testing. The finance team wants to receive a single monthly invoice that shows the total charges from all three accounts combined. They also want to aggregate usage across accounts to benefit from volume discounts on Amazon S3 and Amazon EC2. Additionally, the team wants to apply a single payment method (credit card) to cover charges for all accounts. Which AWS feature should the finance team use to meet these requirements?

A.AWS Budgets
B.AWS Cost Explorer
C.Consolidated Billing through AWS Organizations
D.AWS Cost and Usage Report
AnswerC

Consolidated Billing is a feature of AWS Organizations that combines usage and costs from all member accounts into a single invoice, allows volume discounts based on aggregated usage, and supports a single payment method for the entire organization.

Why this answer

Consolidated Billing through AWS Organizations is the correct feature because it allows the finance team to link multiple AWS accounts under a single organization, enabling a single monthly invoice that aggregates charges from all accounts. This aggregation also combines usage across accounts for services like Amazon S3 and Amazon EC2, allowing the team to benefit from volume discounts. Additionally, Consolidated Billing supports a single payment method (credit card) that covers charges for all linked accounts, meeting all stated requirements.

Exam trap

The trap here is that candidates may confuse cost management tools (like Budgets or Cost Explorer) with billing consolidation features, not realizing that only Consolidated Billing through AWS Organizations provides the single invoice, aggregated usage, and unified payment method required.

Why the other options are wrong

A

AWS Budgets allows you to set cost and usage thresholds and receive alerts, but it does not combine multiple accounts into a single invoice, aggregate usage for volume discounts, or apply a single payment method.

B

AWS Cost Explorer provides visualization and analysis of costs and usage, but it does not consolidate billing across multiple accounts, aggregate usage for volume discounts, or enable a single payment method.

D

AWS Cost and Usage Report (CUR) provides detailed cost and usage data but does not consolidate billing across accounts, aggregate usage for volume discounts, or enable a single payment method. It is a reporting tool, not a billing consolidation feature.

MCQmedium

A company is planning to migrate a legacy application to AWS and wants to estimate the monthly cost of running the new workload. The company needs to compare costs across different Amazon EC2 instance types, regions, and pricing models (On-Demand, Reserved, and Spot). The team also wants to include estimated costs for related services such as Amazon EBS storage and data transfer. Which AWS tool should the company use to generate this cost estimate?

A.AWS Pricing Calculator
B.AWS Cost Explorer
C.AWS Budgets
D.AWS Trusted Advisor
AnswerA

Correct. The AWS Pricing Calculator is designed to produce cost estimates for new AWS workloads. You can select specific EC2 instance types, pricing models, regions, and associated services like EBS and data transfer to get a monthly estimate.

Why this answer

The AWS Pricing Calculator (formerly the Simple Monthly Calculator) is the correct tool because it allows users to estimate monthly costs by selecting specific EC2 instance types, regions, and pricing models (On-Demand, Reserved, Spot), and it also includes estimates for related services like EBS storage and data transfer. This tool provides a detailed, upfront cost comparison before any resources are deployed, which directly matches the company's requirement to compare costs across different configurations.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer (which analyzes past costs) with the AWS Pricing Calculator (which estimates future costs), especially since both tools deal with cost data and are found in the Billing and Cost Management console.

Why the other options are wrong

B

AWS Cost Explorer analyzes historical costs and usage, but cannot generate upfront cost estimates for migrating to different instance types, regions, or pricing models before deployment.

C

AWS Budgets is used to set cost and usage budgets and receive alerts when you exceed or are forecasted to exceed them, not to generate upfront cost estimates for migration planning.

D

AWS Trusted Advisor provides recommendations for cost optimization, performance, security, and fault tolerance, but it does not allow you to generate upfront cost estimates for different EC2 instance types, regions, and pricing models before migration.

MCQmedium

A healthcare company runs a production application on AWS that stores protected health information (PHI). The company needs a support plan that provides a designated Technical Account Manager (TAM) who will perform quarterly business reviews, offer proactive architectural guidance, and help optimize the environment. The company also requires a 15-minute response time for critical system failures. Which AWS Support plan should the company choose?

A.AWS Basic Support
B.AWS Developer Support
C.AWS Business Support
D.AWS Enterprise Support
AnswerD

AWS Enterprise Support is the only plan that includes a dedicated Technical Account Manager (TAM), who acts as a single point of contact for proactive guidance, operational health, and architectural review. It also provides a 15-minute response for critical production outages, alongside full Trusted Advisor, the AWS Health API, and quarterly business reviews. For a production application in healthcare with strict availability and compliance needs, Enterprise Support aligns exactly with the stated requirement for a TAM.

Why this answer

AWS Enterprise Support is the only plan that provides a designated Technical Account Manager (TAM) who conducts quarterly business reviews, offers proactive architectural guidance, and helps optimize the environment. It also guarantees a 15-minute response time for critical system failures, meeting the healthcare company's requirements for handling protected health information (PHI) with high availability and compliance.

Exam trap

The trap here is that candidates often confuse AWS Business Support's 1-hour critical response time and general architectural guidance with the dedicated TAM and quarterly business reviews that are exclusive to Enterprise Support, leading them to select Business Support instead.

Why the other options are wrong

A

AWS Basic Support does not provide a Technical Account Manager (TAM), quarterly business reviews, proactive architectural guidance, or a 15-minute response time for critical failures. It only offers basic support for account and billing issues.

B

AWS Developer Support does not provide a designated Technical Account Manager (TAM), quarterly business reviews, or proactive architectural guidance, and its response time for critical cases is 1 hour, not 15 minutes.

MCQeasy

Which AWS service or feature provides a notification when AWS is performing planned maintenance that may affect your resources?

A.Amazon CloudWatch Alarms
B.AWS Health Dashboard
C.AWS Trusted Advisor
D.AWS Config
AnswerB

The AWS Health Dashboard delivers account-specific and resource-specific notifications about planned lifecycle events, including scheduled maintenance, service disruptions, and other AWS-initiated changes. It proactively alerts you with a personalized view of events that affect your resources, and you can even automate responses by integrating these events with Amazon EventBridge.

Why this answer

AWS Health Dashboard (specifically the AWS Personal Health Dashboard) provides proactive notifications and alerts when AWS is performing planned maintenance that may affect your resources. It gives you a personalized view of service health events, including scheduled maintenance, that are relevant to your AWS account and resources.

Exam trap

The trap here is that candidates often confuse the AWS Service Health Dashboard (public, region-wide status) with the AWS Personal Health Dashboard (account-specific alerts), or mistakenly think CloudWatch Alarms can capture AWS-side maintenance events via custom metrics.

How to eliminate wrong answers

Option A is wrong because Amazon CloudWatch Alarms monitor metrics (e.g., CPU utilization, latency) and trigger actions based on thresholds you define, but they do not natively receive or relay AWS-planned maintenance notifications. Option C is wrong because AWS Trusted Advisor inspects your environment and makes recommendations to optimize cost, performance, security, and fault tolerance, but it does not provide real-time alerts for planned maintenance events. Option D is wrong because AWS Config evaluates your resource configurations against desired policies and tracks configuration changes, but it is not designed to notify you of AWS-side planned maintenance activities.

82
MCQmedium

A company is planning to migrate a legacy application to AWS. The solutions architect needs to estimate the monthly cost of running Amazon EC2 instances, Amazon RDS databases, and Amazon S3 storage. The architect wants to compare different instance types, storage classes, and pricing models (e.g., On-Demand vs. Reserved Instances) to find the most cost-effective configuration. The team requires a tool that provides a detailed, itemized cost estimate without incurring any actual charges, and allows saving and sharing the estimate with stakeholders. Which AWS tool should the solutions architect use?

A.AWS Budgets
B.AWS Cost Explorer
C.AWS Pricing Calculator
D.AWS Cost and Usage Report
AnswerC

The AWS Pricing Calculator is specifically built to create cost estimates for planned AWS usage. Users can configure services, select pricing models, and receive a detailed monthly estimate. Estimates can be saved, shared, and refined without any actual spend.

Why this answer

The AWS Pricing Calculator (formerly AWS Simple Monthly Calculator) is the correct tool because it allows users to build a detailed, itemized cost estimate for AWS services like EC2, RDS, and S3 without incurring any actual charges. It supports comparing different instance types, storage classes, and pricing models (On-Demand vs. Reserved Instances), and provides a shareable link to save and share the estimate with stakeholders.

Exam trap

The trap here is confusing tools that analyze past costs (Cost Explorer, Cost and Usage Report) with tools that estimate future costs (Pricing Calculator), leading candidates to pick Cost Explorer because it also shows cost breakdowns, but it cannot model a greenfield migration without historical data.

Why the other options are wrong

A

AWS Budgets is used to set spending limits and receive alerts, not to generate detailed, itemized cost estimates for comparing configurations before incurring charges.

B

AWS Cost Explorer analyzes historical costs and usage, but does not provide upfront cost estimates for planned configurations without incurring actual charges.

D

AWS Cost and Usage Report provides detailed billing data after charges have been incurred, not a pre-migration cost estimate without actual charges. It cannot compare instance types or pricing models before deployment.

83
MCQmedium

A company has multiple departments (HR, Finance, Engineering) sharing a single AWS account. Each department tags its resources with a 'Department' tag (e.g., Department:HR). The finance team wants to set monthly spending limits for each department and receive email alerts when a department's spending reaches 80% of its limit. They also want a visual dashboard to compare actual spending against the budgeted amounts. Which combination of AWS services should the finance team use?

A.AWS Cost Explorer and AWS Trusted Advisor
B.AWS Budgets and Amazon QuickSight
C.AWS Budgets and AWS Cost Explorer
D.AWS Pricing Calculator and AWS Cost Explorer
AnswerC

Correct. AWS Budgets allows the finance team to create monthly cost budgets per department (using cost allocation tags) and configure alerts at 80% of the budgeted amount. AWS Cost Explorer provides a visual dashboard with charts and tables to compare actual spending against budgets, enabling the team to track progress without needing an external BI tool.

Why this answer

AWS Budgets allows the finance team to set monthly spending limits per department (using the 'Department' tag) and configure alerts at 80% of the budget. AWS Cost Explorer provides a visual dashboard to compare actual spending against budgeted amounts, enabling trend analysis and cost allocation tracking. Together, they fulfill both the alerting and visualization requirements.

Exam trap

The trap here is that candidates may think Amazon QuickSight is needed for visualization, but AWS Cost Explorer already provides built-in charts and dashboards for comparing actual vs. budgeted costs, making QuickSight unnecessary for this specific requirement.

Why the other options are wrong

A

AWS Trusted Advisor does not provide budget alerts or spending limits by tag; it offers cost optimization checks but not per-department budget tracking or email alerts at spending thresholds.

B

AWS Budgets can send alerts, but Amazon QuickSight is not needed for a visual dashboard comparing actual vs. budgeted spending; AWS Cost Explorer provides that visualization directly. QuickSight is an overkill and not the simplest solution for this requirement.

D

AWS Pricing Calculator is used for estimating future costs, not for setting budgets, tracking spending, or creating dashboards. It cannot send alerts or provide a visual comparison of actual vs. budgeted spending.

84
MCQmedium

A startup is designing a new application on AWS. They have selected specific Amazon EC2 instance types, Amazon EBS volumes, and estimated data transfer. The team wants to compare the monthly cost of running the application using On-Demand instances versus 1-year All Upfront Reserved Instances before they commit to any resources. Which AWS tool should they use to generate this cost estimate?

A.AWS Cost Explorer
B.AWS Budgets
C.AWS Pricing Calculator
D.AWS Trusted Advisor
AnswerC

The AWS Pricing Calculator is the intended tool for estimating costs before deployment. You can specify the exact services and configurations for your new application—such as EC2 instance types, storage volumes, and data transfer—and it computes a monthly estimate, including the ability to compare On-Demand, Reserved, and Savings Plans pricing. Because you have already selected the specific AWS services, this tool lets you model that architecture and produce a detailed cost projection to support design decisions.

Why this answer

AWS Pricing Calculator (option C) is the correct tool because it allows users to estimate the monthly cost of AWS services, including EC2 instances, EBS volumes, and data transfer, before deployment. It supports comparing pricing models such as On-Demand and 1-year All Upfront Reserved Instances by letting you input specific instance types, storage, and transfer details to generate a detailed cost breakdown. This matches the startup's need to compare costs without committing to resources.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer (which analyzes existing costs) with the AWS Pricing Calculator (which estimates future costs for new deployments), leading them to select Cost Explorer for a scenario that requires pre-deployment cost comparison.

Why the other options are wrong

A

AWS Cost Explorer analyzes historical cost data and provides forecasts, but it cannot generate cost estimates for hypothetical scenarios before resources are launched, such as comparing On-Demand vs. Reserved Instance pricing for a new application.

B

AWS Budgets is used to set cost and usage alerts, not to generate upfront cost estimates comparing different pricing models like On-Demand vs. Reserved Instances.

D

AWS Trusted Advisor provides recommendations for cost optimization, performance, security, and fault tolerance, but it does not generate cost estimates for comparing pricing models like On-Demand vs. Reserved Instances.

85
MCQmedium

A company runs non-production Amazon EC2 instances for development and testing. The finance team wants to automatically stop all non-production instances if the monthly spending exceeds $5,000. The team wants to set this up without writing custom scripts or using third-party tools. Which AWS feature should the finance team use to meet this requirement?

A.AWS Budgets with a budget action to stop EC2 instances
B.AWS Cost Explorer
C.AWS Trusted Advisor
D.AWS Config
AnswerA

Correct. AWS Budgets natively supports budget actions that automate responses to cost thresholds. You can configure a cost budget, set an alert threshold, and attach an action that stops EC2 instances — either all in the account or a specified subset — using the AWS Budgets service with the appropriate IAM role. This runs without custom scripts or external tooling, and can trigger on either forecasted or actual spend.

Why this answer

AWS Budgets allows you to set a cost budget (e.g., $5,000) and attach a budget action that triggers an AWS Systems Manager (SSM) automation document to stop EC2 instances when the actual or forecasted spend exceeds the threshold. This meets the requirement without custom scripts or third-party tools, as the budget action natively integrates with EC2 via SSM.

Exam trap

The trap here is that candidates confuse AWS Budgets (a cost management tool) with AWS Config (a compliance tool) or Trusted Advisor (a recommendation engine), assuming those can enforce actions, but only Budgets with budget actions provides the automated, threshold-based stop capability without custom code.

Why the other options are wrong

B

AWS Cost Explorer provides cost visualization and analysis but cannot automatically take actions like stopping EC2 instances based on spending thresholds.

C

AWS Trusted Advisor provides cost optimization recommendations but cannot automatically stop EC2 instances based on spending thresholds; it lacks native budget action capabilities.

D

AWS Config is a service for resource inventory, configuration history, and compliance auditing, not for cost-based automated actions. It cannot directly stop EC2 instances based on spending thresholds.

86
MCQmedium

A company runs a development environment composed of multiple Amazon EC2 instances. The finance team has set a monthly budget of $5,000 for this environment and wants to automatically stop all EC2 instances if the accumulated cost reaches $4,500 before the end of the month. The team needs a managed AWS-native solution that does not require custom scripts or third-party tools. Which AWS feature or service should the company use to meet this requirement?

A.AWS Budgets with a budget action that stops EC2 instances when the threshold is exceeded
B.AWS Cost Explorer with a saved filter and manual instance termination
C.AWS Trusted Advisor cost optimization checks
D.AWS Organizations Service Control Policies (SCPs)
AnswerA

AWS Budgets supports budget actions that can automate responses to cost or usage threshold breaches. You can configure an action to stop Amazon EC2 instances, which directly satisfies the requirement without custom scripts.

Why this answer

AWS Budgets allows you to set a cost budget with an associated budget action that can automatically stop EC2 instances when the actual or forecasted cost exceeds a specified threshold (e.g., $4,500). This is a fully managed, native AWS solution that requires no custom scripts or third-party tools, directly meeting the requirement to stop instances automatically based on cost.

Exam trap

The trap here is that candidates may confuse AWS Cost Explorer's visualization capabilities with automated cost control actions, or mistakenly think Trusted Advisor can enforce cost limits, when only AWS Budgets with budget actions provides native, automated instance stopping based on cost thresholds.

Why the other options are wrong

B

AWS Cost Explorer does not support automated actions like stopping instances; it only provides cost visualization and filtering, requiring manual termination which violates the 'automatically stop' requirement.

C

Trusted Advisor cost optimization checks provide recommendations to reduce costs but cannot automatically stop EC2 instances based on a budget threshold.

87
MCQmedium

A company is migrating a steady-state web server to AWS. The server is expected to run continuously (24 hours a day, 7 days a week) for the next three years. The workload has predictable CPU and memory usage and does not experience significant spikes. The company wants to minimize the total cost of running this server over the three-year period. Which AWS EC2 pricing model should the company choose?

A.On-Demand Instances
B.Spot Instances
C.Standard Reserved Instances with a 3-year term and all upfront payment
D.Dedicated Hosts
AnswerC

Standard Reserved Instances provide a substantial discount over On-Demand pricing when you commit to a 1- or 3-year term. Paying all upfront gives the highest discount, making this the most cost-effective option for a predictable, long-running workload.

Why this answer

Standard Reserved Instances with a 3-year term and all upfront payment provide the highest discount (up to 72% compared to On-Demand) for workloads that run continuously and predictably. Since this server will run 24/7 for three years with no significant spikes, a 3-year all upfront Reserved Instance minimizes total cost by locking in the lowest effective hourly rate.

Exam trap

AWS often tests the misconception that Spot Instances are always cheaper and can be used for any workload, but the trap here is that Spot Instances are interruptible and thus unsuitable for continuous, steady-state production servers.

Why the other options are wrong

A

On-Demand Instances have no upfront commitment and are billed per hour, making them more expensive than Reserved Instances for a steady-state workload running continuously for three years.

B

Spot Instances can be interrupted with little notice, making them unsuitable for a steady-state web server that must run continuously for three years.

D

Dedicated Hosts provide physical servers dedicated for your use, which is unnecessary for a steady-state web server with predictable usage and no compliance requirements for physical isolation, leading to higher costs compared to Reserved Instances.

88
MCQeasy

A company is concerned about unexpected AWS charges from development instances that developers forget to stop. Which AWS service provides a simple dashboard showing AWS service health events and can also be used to stay informed about account-level events?

A.AWS Trusted Advisor
B.Amazon CloudWatch
C.AWS Health Dashboard (Personal Health Dashboard)
D.AWS Config
AnswerC

AWS Health Dashboard provides personalized, account-specific notifications about AWS service events, planned maintenance, and security notifications that may affect your resources.

Why this answer

The AWS Health Dashboard (Personal Health Dashboard) provides a personalized view of the health of AWS services and resources that affect your account, including scheduled maintenance, security notifications, and other account-level events. While it does not directly show billing alerts, it helps you stay informed about service-related events that could impact your resources. For billing alerts, you would use Amazon CloudWatch or AWS Budgets.

Exam trap

The trap here is that candidates often confuse the AWS Health Dashboard (Personal Health Dashboard) with the AWS Service Health Dashboard (the public status page at status.aws.amazon.com), which shows only global service health and not account-specific events or billing alerts.

How to eliminate wrong answers

Option A is wrong because AWS Trusted Advisor inspects your AWS environment and makes recommendations for cost optimization, performance, security, and fault tolerance, but it does not provide a dashboard for service health events or account-level event notifications. Option B is wrong because Amazon CloudWatch monitors metrics and logs for your AWS resources and applications, and can trigger alarms based on thresholds, but it is not a dedicated dashboard for AWS service health events or account-level events. Option D is wrong because AWS Config evaluates your resource configurations against desired policies and tracks configuration changes, but it does not provide a dashboard for service health events or account-level billing events.

89
MCQmedium

A company wants to purchase EC2 capacity that provides a discount over On-Demand pricing and is available only when AWS has excess capacity, with the option of interruption with a 2-minute warning. Which option is this?

A.Reserved Instances
B.On-Demand Instances
C.Spot Instances
D.Dedicated Instances
AnswerC

Spot Instances are the only option that meets the scenario's requirements: they let you use AWS's unused EC2 capacity at a discount of up to 90% compared to On-Demand pricing. The trade-off is that AWS can reclaim this capacity with a 2-minute warning when it needs it back for other workloads, making them ideal for fault-tolerant, interruption-tolerant applications. The discount is directly tied to the availability of spare capacity, and if capacity is no longer available, the instance is interrupted—this matches the scenario precisely.

Why this answer

Spot Instances (Option C) are correct because they offer a significant discount over On-Demand pricing but can be interrupted by AWS with a 2-minute warning when AWS needs the capacity back. This matches the scenario of purchasing EC2 capacity that is available only when AWS has excess capacity and includes the risk of interruption.

Exam trap

The trap here is that candidates often confuse Spot Instances with Reserved Instances, thinking any discount means a commitment, but Spot Instances are interruptible and based on excess capacity, not a fixed-term contract.

How to eliminate wrong answers

Option A is wrong because Reserved Instances provide a discount in exchange for a 1- or 3-year commitment, not based on excess capacity, and they are not interruptible. Option B is wrong because On-Demand Instances have no discount, no interruption risk, and are always available at a fixed price. Option D is wrong because Dedicated Instances are physically isolated at the host hardware level for compliance or licensing, but they are billed on an On-Demand or Reserved basis and do not offer a discount tied to excess capacity or interruption.

90
MCQmedium

A company has 20 AWS accounts managed under AWS Organizations. The finance team wants to centralize billing so that the company receives volume discounts for the aggregated usage across all accounts. Additionally, the team needs to set monthly budgets for each department and automatically receive email notifications when a department's spending reaches 80% of its budget threshold. Which combination of AWS features or services should the company use to meet these requirements?

A.AWS Cost Explorer with AWS Budgets
B.Consolidated Billing with AWS Budgets
C.AWS Trusted Advisor with Consolidated Billing
D.AWS Cost Explorer with AWS Organizations
AnswerB

Consolidated Billing in AWS Organizations aggregates all account usage into a single bill, enabling the company to receive volume discounts (e.g., tiered pricing for EC2, S3). AWS Budgets allows the finance team to set custom budgets for each department and automatically send email notifications when actual or forecasted costs reach a defined threshold (e.g., 80%). This combination meets both requirements.

Why this answer

Consolidated Billing aggregates usage across all accounts in AWS Organizations, enabling volume discounts. AWS Budgets allows setting monthly budgets per department and configuring alerts (e.g., at 80% threshold) to send email notifications via Amazon SNS. Together, they meet both centralization and notification requirements.

Exam trap

The trap here is confusing AWS Cost Explorer (a visualization tool) with AWS Budgets (an alerting tool), leading candidates to pick A or D, which lack the automated notification mechanism.

Why the other options are wrong

A

AWS Cost Explorer is a visualization tool for cost and usage data, not a billing consolidation mechanism. It does not aggregate accounts for volume discounts, which requires Consolidated Billing.

C

AWS Trusted Advisor provides cost optimization recommendations but does not enable centralized billing for volume discounts or allow setting budgets with automated notifications. Consolidated Billing is required for aggregated usage and volume discounts, and AWS Budgets is needed for budget thresholds and alerts.

D

AWS Cost Explorer is a visualization tool for cost and usage data, not a billing consolidation feature. It does not enable volume discounts across accounts or automate budget alerts; AWS Organizations provides consolidated billing, but Cost Explorer alone cannot set budgets or send notifications.

91
MCQmedium

A company has been using Amazon EC2 instances for a production application for the past 12 months. The finance team wants to understand historical spending patterns and identify opportunities to reduce costs. Specifically, they need to see which EC2 instance families and sizes are being underutilized and get recommendations for purchasing Reserved Instances to save money compared to current On-Demand pricing. The team wants to use a native AWS tool that provides a visual dashboard of costs, usage trends, and actionable recommendations. Which AWS tool should the finance team use?

A.AWS Budgets
B.AWS Trusted Advisor
C.AWS Cost Explorer
D.AWS Compute Optimizer
AnswerC

AWS Cost Explorer is the correct tool. It provides an interactive dashboard of historical costs and usage, allows filtering by EC2 instance family, and generates Reserved Instance purchase recommendations based on your past usage. It is specifically designed for cost analysis and optimization.

Why this answer

AWS Cost Explorer is the correct choice because it provides a visual dashboard of historical cost and usage data, including the ability to filter by EC2 instance families and sizes to identify underutilized resources. It also offers Reserved Instance (RI) purchase recommendations based on historical On-Demand usage, enabling the finance team to compare costs and identify savings opportunities directly within the native AWS console.

Exam trap

The trap here is that candidates often confuse AWS Compute Optimizer (which focuses on right-sizing) with Cost Explorer (which provides both historical cost visualization and RI purchase recommendations), leading them to choose D instead of C.

Why the other options are wrong

A

AWS Budgets allows you to set cost and usage budgets and receive alerts, but it does not provide a visual dashboard of historical spending patterns, underutilized EC2 instance families, or specific Reserved Instance purchase recommendations.

B

AWS Trusted Advisor provides cost optimization recommendations, but it does not offer a visual dashboard of historical cost and usage trends or detailed Reserved Instance purchase recommendations. The question specifically requires a tool with a visual dashboard for historical spending analysis and RI recommendations, which is AWS Cost Explorer.

D

AWS Compute Optimizer provides recommendations for optimal instance types and sizes based on utilization, but it does not offer a visual dashboard of historical cost and usage trends or Reserved Instance purchase recommendations. The question specifically requires a tool for historical spending analysis and RI recommendations, which is Cost Explorer's function.

92
MCQmedium

A company has a development environment running on Amazon EC2 instances. To control costs, the team wants to set a monthly budget of $5,000 for this environment. If the forecasted cost for the month exceeds $6,000 (20% over budget), they want AWS to automatically stop all non-critical EC2 instances to prevent further spending. Which AWS feature should the team use to implement this automated cost control?

A.AWS Cost Explorer
B.AWS Budgets with budget actions
C.AWS Trusted Advisor
D.AWS Cost Anomaly Detection
AnswerB

AWS Budgets enables you to set custom budgets (e.g., monthly cost budget). With budget actions, you can configure automated responses when actual or forecasted costs exceed budget thresholds. For example, you can define an action to stop non-critical EC2 instances when the forecast exceeds $6,000. This fully meets the requirement.

Why this answer

AWS Budgets with budget actions allows you to set a monthly budget of $5,000 and define an action that triggers when the forecasted cost exceeds a specified threshold (e.g., 20% over budget, or $6,000). The action can automatically stop non-critical EC2 instances using an IAM role and a predefined runbook, directly enforcing cost control without manual intervention. This is the only AWS feature that combines budget monitoring with automated remediation actions.

Exam trap

The trap here is that candidates confuse AWS Budgets (which can trigger actions) with AWS Cost Explorer (which only provides reporting) or AWS Cost Anomaly Detection (which only alerts), failing to recognize that only AWS Budgets with budget actions supports automated remediation.

Why the other options are wrong

A

AWS Cost Explorer provides visualization and analysis of costs and usage but does not support automated actions like stopping EC2 instances based on budget thresholds.

D

AWS Cost Anomaly Detection detects unusual spending patterns but does not support automated actions to stop instances based on budget thresholds.

93
MCQmedium

A company is reviewing their AWS bill and notices charges for Amazon CloudWatch. Which specific CloudWatch usage would NOT incur additional charges beyond the CloudWatch free tier?

A.Detailed monitoring (1-minute metrics) for EC2 instances
B.Basic monitoring (5-minute metrics) for EC2 instances
C.Publishing 100 custom metrics
D.Storing CloudWatch Logs beyond the free tier
AnswerB

Basic monitoring is the default CloudWatch monitoring mode for every EC2 instance, automatically enabled when the instance launches. It publishes standard metrics at 5-minute intervals at no additional cost, regardless of how long the instance runs. Because it is the only EC2 monitoring option that is truly free and requires no setup, this is the correct answer.

Why this answer

Basic monitoring for EC2 instances provides metrics at 5-minute intervals at no additional cost, as it is included in the CloudWatch free tier. Detailed monitoring (1-minute metrics) incurs charges because it requires more frequent data collection and storage. Therefore, basic monitoring is the only option that does not generate extra charges beyond the free tier.

Exam trap

The trap here is that candidates assume all CloudWatch monitoring is free, but AWS specifically charges for detailed monitoring and custom metrics beyond the free tier limits, while basic monitoring remains free to encourage foundational observability without upfront costs.

How to eliminate wrong answers

Option A is wrong because detailed monitoring (1-minute metrics) for EC2 instances is a paid feature that incurs additional charges per instance per hour, as it increases the volume of metric data points sent to CloudWatch. Option C is wrong because the CloudWatch free tier includes only 10 custom metrics per month; publishing 100 custom metrics would exceed this limit and incur charges for the additional 90 metrics. Option D is wrong because storing CloudWatch Logs beyond the free tier (5 GB per month) incurs charges for both data ingestion and storage, as the free tier only covers the first 5 GB of log data per account per month.

MCQmedium

A company uses AWS for multiple projects. Each project's resources have been tagged with 'Project' and 'Team' tags. The finance team wants to view a cost breakdown in AWS Cost Explorer using these tags. The tags are already applied to existing resources. However, when the finance team opens Cost Explorer, the tags are not available for filtering. What must the finance team do to see costs by these tags?

A.Enable detailed billing reports in the Billing console.
B.Activate the cost allocation tags in the Billing and Cost Management console.
C.Create a budget in AWS Budgets and set tag-based filters.
D.Use AWS Organizations to create separate accounts per project.
AnswerB

Correct. Cost allocation tags must be activated in the Billing console before they appear in Cost Explorer. Once activated, AWS includes the tag keys and values in cost data, and after up to 24 hours, the tags become available for filtering in Cost Explorer.

Why this answer

Cost allocation tags must be explicitly activated in the Billing and Cost Management console before they appear in AWS Cost Explorer. Even though tags are already applied to resources, AWS does not automatically make them available for cost filtering until they are activated as cost allocation tags. This activation process enables the tags to be recognized by billing and cost management services.

Exam trap

The trap here is that candidates assume applying tags to resources automatically makes them available for cost filtering, but AWS requires a separate activation step in the Billing and Cost Management console to enable cost allocation tags.

Why the other options are wrong

A

Detailed billing reports (legacy) are not required for tag-based filtering in Cost Explorer; tags must be activated as cost allocation tags in the Billing and Cost Management console.

C

Creating a budget with tag-based filters does not make tags available in Cost Explorer; it only sets cost alerts. Tags must first be activated as cost allocation tags to appear in Cost Explorer.

D

Using AWS Organizations to create separate accounts per project is an overly complex and unnecessary step for viewing cost breakdowns by tags; the correct approach is to activate cost allocation tags in the Billing and Cost Management console, which makes existing tags available in Cost Explorer.

95
MCQmedium

A company uses separate AWS accounts for development, testing, and production. The finance team wants to receive a single monthly invoice that covers all accounts and to benefit from volume pricing discounts across the entire organization. Which AWS feature should the company use to achieve this?

A.Enable Consolidated Billing in AWS Organizations
B.Set up an AWS Budget to track all account costs
C.Use Cost Explorer to generate a combined cost report
D.Activate AWS Trusted Advisor on the management account
AnswerA

Enabling Consolidated Billing in AWS Organizations aggregates usage and charges from all member accounts into the management account's single monthly invoice, eliminating the need for separate account-level bills. This also pools usage across included accounts, which helps the organization reach higher volume tiers on qualifying services and benefit from volume-based pricing discounts, along with options to share Reserved Instance and Savings Plans discounts. Because the scenario requires one invoice and aggregated discounts, Consolidated Billing is the correct mechanism.

Why this answer

AWS Organizations with Consolidated Billing allows a company to combine usage across multiple accounts into a single monthly invoice, enabling the organization to aggregate usage and benefit from volume pricing discounts (e.g., tiered pricing for EC2, S3, or data transfer). The management account pays for all member accounts, and the consolidated view simplifies cost tracking while maximizing savings from AWS's graduated pricing model.

Exam trap

The trap here is that candidates confuse cost monitoring tools (Budgets, Cost Explorer) or advisory services (Trusted Advisor) with the billing consolidation feature, which is the only mechanism that combines invoices and unlocks volume discounts across accounts.

Why the other options are wrong

B

AWS Budgets track costs and send alerts, but they do not consolidate billing across multiple accounts or provide volume pricing discounts.

C

Cost Explorer provides cost visualization and analysis, but it does not consolidate billing into a single invoice or enable volume pricing discounts across accounts.

D

AWS Trusted Advisor provides recommendations for cost optimization, security, and performance, but it does not consolidate billing or provide a single invoice across multiple accounts.

96
MCQmedium

A company uses AWS for multiple workloads across several linked accounts under AWS Organizations. The finance team needs to analyze historical cost and usage data to identify monthly spending trends by service (e.g., Amazon EC2, Amazon S3) and by linked account. They also need to filter the data by date range and view the top cost drivers. The team prefers a built-in AWS tool that provides an interactive interface with graphs and tables, without requiring them to download or process raw data. Which AWS service or tool should the finance team use?

A.AWS Cost Explorer
B.AWS Budgets
C.AWS Trusted Advisor
D.AWS Cost and Usage Reports
AnswerA

Correct. AWS Cost Explorer is a built-in AWS tool that provides interactive graphs and tables to explore historical cost and usage data, with filtering by service, linked account, region, and date range. It is designed for visual trend analysis and identifying cost drivers without needing to process raw data.

Why this answer

AWS Cost Explorer is the correct choice because it provides a built-in, interactive interface with pre-built graphs and tables that allow the finance team to analyze historical cost and usage data without downloading or processing raw data. It supports filtering by service (e.g., Amazon EC2, Amazon S3), linked account, and date range, and can identify top cost drivers through customizable views and filtering options.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer with AWS Cost and Usage Reports, assuming both provide the same interactive analysis, but the key differentiator is that Cost Explorer offers a built-in GUI without requiring data downloads or external processing.

Why the other options are wrong

B

AWS Budgets is designed for setting cost alerts and tracking against budgets, not for interactive historical cost and usage analysis with graphs and tables. It lacks the granular filtering and visualization capabilities needed to identify monthly spending trends by service and linked account.

C

AWS Trusted Advisor provides best-practice recommendations for cost optimization, performance, security, and fault tolerance, but it does not offer interactive historical cost and usage analysis with graphs and tables by service and linked account.

D

AWS Cost and Usage Reports (CUR) provides raw data in CSV/Parquet format, not an interactive interface with graphs and tables. The question specifies the team prefers a built-in tool with interactive visuals without downloading or processing raw data, which CUR does not offer.

MCQmedium

A company has multiple AWS accounts that are consolidated under AWS Organizations. The finance team receives a single monthly bill for all accounts. The team needs to allocate costs to individual departments based on which department owns each resource. They want to see a breakdown of costs by department in the monthly cost report without manually combining data from each account. Which action should the finance team take to meet these requirements?

A.Activate cost allocation tags, tag all resources with a department identifier, and use Cost Explorer to filter and group costs by the tag.
B.Set up separate payment methods for each department's AWS account so that each department receives its own bill.
C.Create a dedicated AWS account for each department and manually sum the charges from each account's monthly bill.
D.Use AWS Budgets to set a spending threshold for each department and review the alerts to estimate departmental costs.
AnswerA

Correct. Cost allocation tags allow you to categorize and track AWS costs by department. After activating the tags in the Billing console, Cost Explorer can display cost breakdowns by tag value, enabling department-level cost allocation without manual work.

Why this answer

Activating cost allocation tags and tagging all resources with a department identifier allows the finance team to use Cost Explorer to filter and group costs by that tag. This provides a per-department cost breakdown in the consolidated monthly bill without manual aggregation, leveraging AWS Organizations' consolidated billing and tag-based cost tracking.

Exam trap

The trap here is that candidates may confuse AWS Budgets (which only tracks spending against thresholds) with cost allocation tags and Cost Explorer (which provide actual cost breakdowns), or assume that separate accounts or payment methods are necessary for cost allocation when tags suffice.

Why the other options are wrong

B

Setting up separate payment methods does not provide a consolidated view of costs by department within a single monthly bill; it creates separate bills, which contradicts the requirement to see a breakdown in the monthly cost report without manual combination.

C

Manually summing charges from each account's monthly bill is not automated and does not scale, failing the requirement to avoid manual work.

D

AWS Budgets provides alerts on spending thresholds but does not generate a breakdown of costs by department in the monthly cost report; it lacks the granular tagging and grouping capabilities needed for departmental cost allocation.

MCQmedium

A company runs a critical production application on AWS. The internal team is unable to resolve intermittent errors that are impacting the application. The company currently has the AWS Basic Support plan and requires access to AWS technical support with a faster response time for production issues. Due to budget constraints, the company wants the most cost-effective support plan that provides a response time of 1 hour for production system impaired cases. Which AWS Support plan should the company choose?

A.Developer Support
B.Business Support
C.Enterprise Support
D.Enterprise On-Ramp
AnswerB

The Business Support plan provides a 1-hour response time for production system impaired cases, which directly matches the company's stated requirement. It is the most cost-effective AWS Support plan that offers this level of critical incident response, as it includes 24x7 access to Cloud Support Engineers and full use of AWS Trusted Advisor and Personal Health Dashboard. While higher-tier plans may respond faster, they are overkill for a 1-hour SLA, making Business Support the optimal balance of cost and coverage for this production application.

Why this answer

The AWS Business Support plan is the most cost-effective option that provides a 1-hour response time for production system impaired cases. The Basic Support plan offers no technical support, while the Developer Support plan only provides a 12-hour response time for impaired systems, which does not meet the requirement. Business Support is the lowest-tier plan that includes 1-hour response for production issues, making it the correct choice.

Exam trap

The trap here is that candidates may confuse the Developer Support plan's 12-hour response for production issues with the 1-hour response required, or assume that only Enterprise-level plans offer fast response times, overlooking the Business Support plan as the cost-effective middle ground.

Why the other options are wrong

A

The Developer Support plan does not provide a 1-hour response time for production system impaired cases; it only offers a 12-hour response time for general guidance and system impaired cases.

D

Enterprise On-Ramp Support provides a 1-hour response time for production system impaired cases, but it is designed for organizations with specific needs and is more expensive than Business Support. The question asks for the most cost-effective plan with a 1-hour response time, making Business Support the correct choice.

MCQmedium

A company is considering AWS for their new application. Which tool allows them to compare the cost of running their workloads on AWS versus on-premises, and estimate the potential savings?

A.AWS Cost Explorer
B.AWS Pricing Calculator
C.AWS Budgets
D.AWS Trusted Advisor
AnswerB

AWS Pricing Calculator estimates costs for AWS architectures and supports TCO analysis comparing on-premises infrastructure costs versus AWS cloud costs for migration business cases.

Why this answer

AWS Pricing Calculator (formerly TCO Calculator) is specifically designed to compare the cost of running workloads on AWS versus on-premises environments. It allows users to input their current on-premises infrastructure details (such as server specifications, storage, and network usage) and generates a detailed cost comparison, including estimated savings from migrating to AWS. This directly matches the question's requirement for comparing costs and estimating potential savings.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer (which shows historical AWS spending) with the AWS Pricing Calculator (which is used for upfront cost comparison and estimation before migration), leading them to select Cost Explorer incorrectly.

How to eliminate wrong answers

Option A is wrong because AWS Cost Explorer is a tool for visualizing, understanding, and managing AWS costs and usage over time, not for comparing on-premises costs to AWS. Option C is wrong because AWS Budgets is used to set custom cost and usage budgets and receive alerts when thresholds are exceeded, not for cost comparison or savings estimation. Option D is wrong because AWS Trusted Advisor inspects your AWS environment and provides recommendations to save money, improve performance, and close security gaps, but it does not compare on-premises costs to AWS costs.

MCQmedium

A company has multiple AWS accounts managed under AWS Organizations with consolidated billing enabled. The company purchases a 3-year Compute Savings Plan to reduce costs on Amazon EC2, AWS Fargate, and AWS Lambda usage. The finance team wants the discount from the Savings Plan to apply to eligible usage across all accounts in the organization. What configuration is required to achieve this?

A.The Savings Plan must be purchased in the management account, and the discount automatically applies to all accounts in the organization.
B.The Savings Plan must be purchased separately in each account where the discount is needed.
C.The finance team must create custom cost allocation tags to distribute the Savings Plan discount across accounts.
D.The Savings Plan must be linked to each member account using the AWS Billing Conductor.
AnswerA

In an AWS Organization with consolidated billing, the management account acts as the payer account. A Savings Plan purchased there is a single hourly commitment that applies to the combined eligible compute usage (EC2, Fargate, and Lambda) of all member accounts. The discount is automatically applied to qualifying usage wherever it occurs across the organization, with no need to purchase or link anything per member account.

Why this answer

When a Compute Savings Plan is purchased in the management account of an AWS Organization with consolidated billing enabled, the discount is automatically shared across all member accounts. This is because consolidated billing aggregates all usage across the organization, and Savings Plans apply discounts to the combined eligible usage, regardless of which account incurred the cost.

Exam trap

The trap here is that candidates may think Savings Plans need to be purchased in each account or require additional configuration like tags or Billing Conductor, when in fact consolidated billing automatically shares the discount across the entire organization.

Why the other options are wrong

B

Savings Plans purchased in the management account automatically apply to all accounts in the organization when consolidated billing is enabled, so separate purchases are unnecessary and would not provide additional benefit.

C

Savings Plans discounts are automatically applied to eligible usage across all accounts in an AWS Organization when purchased in the management account; custom cost allocation tags are used for tracking costs, not for distributing discounts.

D

AWS Billing Conductor is a tool for custom billing and reporting, not for applying Savings Plan discounts. Savings Plan discounts are automatically shared across all accounts in an organization when purchased in the management account, without needing to link plans to accounts via Billing Conductor.

MCQmedium

A company has a monthly budget of $10,000 for its development AWS account. The project manager wants to receive an automated email alert when the actual costs for the current month reach 80% of the budget. The project manager does not want to build any custom code or manage any infrastructure for this alert. Which approach should the project manager take to meet these requirements?

A.Create a budget in AWS Budgets for the account, set the budget amount to $10,000, configure an alert for actual cost at 80% of the budget amount, and specify an email address to receive the notification.
B.Create a cost allocation tag in the Billing and Cost Management console, then configure an Amazon SNS topic to send an email when the tag's cost reaches $8,000.
C.Create a usage report in AWS Cost Explorer, set a forecast alert at 80% of the monthly budget, and configure the report to be sent via email.
D.Create an AWS Lambda function that queries the AWS Cost Explorer API daily, compares actual cost to the budget, and sends an email if costs exceed $8,000.
AnswerA

Correct. AWS Budgets allows you to set a cost budget and define alerts for actual or forecasted costs. When the actual costs reach the 80% threshold, Budgets sends a notification to the specified email address. This is a fully managed feature with no custom code or infrastructure required.

Why this answer

AWS Budgets allows you to set a monthly budget of $10,000 and configure an alert to trigger when actual costs reach 80% ($8,000). The alert can send an email notification directly without requiring any custom code or infrastructure management, meeting the project manager's requirements exactly.

Exam trap

The trap here is that candidates may overcomplicate the solution by choosing a custom-coded approach (Lambda) or a reporting tool (Cost Explorer) when AWS Budgets provides a simple, managed, and code-free alerting mechanism directly in the Billing and Cost Management console.

Why the other options are wrong

B

Cost allocation tags are used for tracking and categorizing costs, not for setting budgets or alerts. Amazon SNS alone cannot monitor costs or trigger alerts based on tag cost thresholds without custom code.

C

AWS Cost Explorer does not support setting alerts or automated email notifications; it is a visualization and analysis tool only.

D

The project manager does not want to build any custom code or manage any infrastructure, but this option requires creating and managing an AWS Lambda function, which violates that constraint.

102
MCQmedium

A company plans to migrate its on-premises workload to AWS. The finance team wants to compare the total cost of ownership between running the workload on-premises and running it on AWS. They need to estimate monthly costs for different Amazon EC2 instance types, pricing models (On-Demand, Reserved, Spot), and storage options before making any commitment. Which AWS tool should the finance team use to create this detailed cost estimate?

A.AWS Pricing Calculator
B.AWS Budgets
C.AWS Cost Explorer
D.AWS Trusted Advisor
AnswerA

AWS Pricing Calculator is a web-based cost estimation tool that lets you define a workload's architecture—such as EC2 instance types, storage, data transfer, and region—and then produces a monthly cost estimate. It supports comparing On-Demand vs. Savings Plans vs. Reserved Instance pricing, and it can generate a total cost of ownership (TCO) report against on-premises costs, making it the appropriate tool for pre-migration cost planning.

Why this answer

AWS Pricing Calculator is the correct tool because it allows users to create detailed cost estimates for AWS services, including EC2 instance types, pricing models (On-Demand, Reserved, Spot), and storage options, before any commitment. It provides a granular breakdown of monthly costs, enabling a total cost of ownership (TCO) comparison between on-premises and AWS workloads. This aligns directly with the finance team's requirement to estimate costs without incurring actual usage.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer (a historical analysis tool) with the AWS Pricing Calculator (a pre-provisioning estimation tool), because both deal with cost data, but Cost Explorer cannot generate estimates for hypothetical configurations.

Why the other options are wrong

B

AWS Budgets is used to set spending limits and receive alerts, not to create detailed cost estimates for comparing on-premises vs. AWS TCO.

C

AWS Cost Explorer analyzes historical costs and usage, but cannot create a detailed cost estimate for a planned migration before any resources are deployed.

D

AWS Trusted Advisor provides recommendations for cost optimization, performance, security, and fault tolerance, but it does not allow users to create custom cost estimates for comparing on-premises vs. AWS workloads before migration.

MCQeasy

Which AWS support plan provides access to AWS Infrastructure Event Management (IEM) for product launches and migrations at no additional charge?

A.Developer Support
B.Business Support
C.Enterprise Support
D.Basic Support
AnswerC

Enterprise Support is the highest AWS Support tier and includes Infrastructure Event Management (IEM) at no extra charge. This means AWS infrastructure specialists work proactively with your team before, during, and after a critical business event — such as a major product launch or a large migration — to validate architecture, identify risks, and provide real-time operational support. Because IEM is bundled into the Enterprise plan, you do not need a separate purchase order to access these specialized resources.

Why this answer

The Enterprise Support plan includes AWS Infrastructure Event Management (IEM) at no additional charge, providing architectural and scaling guidance for product launches and migrations. This is a key differentiator from lower-tier plans, which either do not include IEM or require an extra fee. The Business Support plan offers IEM only as a paid add-on, while Developer and Basic plans lack access entirely.

Exam trap

The trap here is that candidates often assume the Business Support plan includes IEM for free because it offers a higher level of support than Developer, but AWS explicitly reserves complimentary IEM for Enterprise Support, while Business requires an additional fee.

How to eliminate wrong answers

Option A is wrong because the Developer Support plan does not include IEM; it is designed for early development and testing with no access to event management. Option B is wrong because the Business Support plan offers IEM only as a paid add-on, not at no additional charge. Option D is wrong because the Basic Support plan provides only account and billing support with no access to IEM or any proactive guidance.

MCQmedium

A company runs a production MySQL database on Amazon RDS. The workload has a steady baseline usage that requires a db.r5.large instance most of the time, but during end-of-month processing, the database needs to scale up to a db.r5.xlarge for a few days. The company wants to maximize cost savings while retaining the ability to temporarily scale up the instance during those peaks and still receive a discounted rate. Which purchasing option should the company choose?

A.Standard Reserved Instance
B.Convertible Reserved Instance
C.Compute Savings Plan
D.On-Demand
AnswerB

Convertible Reserved Instances for RDS offer the flexibility to modify instance attributes (such as size) during the commitment term while still receiving a discounted rate. This allows the company to temporarily scale up to a db.r5.xlarge during peak periods without losing the RI discount.

Why this answer

Convertible Reserved Instances (RIs) allow you to change instance attributes (such as size) during the term, which fits the need to temporarily scale from db.r5.large to db.r5.xlarge for a few days each month. They offer a significant discount over On-Demand pricing (typically 30-50%) while retaining flexibility to modify the instance type. Standard RIs lock you into a specific instance family and size, making them unsuitable for this variable workload.

Exam trap

The trap here is that candidates often confuse Compute Savings Plans with RDS Reserved Instances, not realizing that Compute Savings Plans only apply to EC2 and Fargate, not to RDS database instances.

Why the other options are wrong

A

Standard Reserved Instances require a fixed instance size (e.g., db.r5.large) and cannot be changed to a larger size (db.r5.xlarge) during peak periods, so they do not support the temporary scaling needed.

C

Compute Savings Plans apply to compute usage across EC2, Fargate, and Lambda, but not to RDS instance modifications. They do not allow scaling RDS instance sizes like Convertible RIs do.

D

On-Demand pricing does not provide any discount or reservation, so it fails to maximize cost savings for the steady baseline usage. The company needs a discounted rate, which On-Demand does not offer.

105
MCQmedium

A company runs multiple applications across hundreds of Amazon EC2 instances in several AWS accounts. The finance team needs to perform daily cost analysis by combining detailed usage data (including instance type, operating system, and custom cost allocation tags) with their own business data stored in an on-premises data warehouse. They want to export cost and usage data from AWS at the most granular level possible (down to each individual resource and hour) into their on-premises system for custom reporting. Which AWS tool should they use to achieve this?

A.AWS Cost Explorer
B.AWS Budgets
C.AWS Cost and Usage Report
D.AWS Trusted Advisor
AnswerC

The AWS Cost and Usage Report delivers the most comprehensive set of cost and usage data, including hourly granularity, resource-level details, and custom tags. It is delivered to an S3 bucket, enabling further analysis or integration with other systems.

Why this answer

AWS Cost and Usage Report (CUR) is the correct choice because it provides the most granular cost and usage data available, down to individual resource IDs and hourly intervals, and supports custom cost allocation tags. It can be delivered to an Amazon S3 bucket and then integrated with on-premises systems for custom reporting, meeting the finance team's requirement for detailed daily cost analysis combined with their own business data.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer's visualization capabilities with the raw data export requirement, overlooking that CUR is the only service that provides hourly, resource-level data with custom tags for external integration.

Why the other options are wrong

A

AWS Cost Explorer provides visualization and analysis of cost data but does not support exporting detailed hourly usage data with custom tags to an on-premises system. It is designed for interactive querying, not granular data export.

B

AWS Budgets is used for setting cost and usage alerts, not for exporting granular hourly cost and usage data to an on-premises system.

A company runs a production workload on AWS and needs technical support that includes phone and email access with a response time of less than 1 hour for critical system failures. The company also wants architectural guidance for cost optimization and performance improvement. The company currently has an AWS account with the Basic Support plan. Which AWS Support plan should the company choose to meet these requirements at the most cost-effective price?

A.Basic Support
B.Developer Support
C.Business Support
D.Enterprise Support
AnswerC

The Business Support plan includes phone and email support, a 1-hour response time for critical failures, and access to architectural guidance for cost optimization and performance. It is the most cost-effective plan that satisfies all the stated requirements.

Why this answer

The Business Support plan is the most cost-effective option that provides phone and email support with a response time of under 1 hour for critical system failures, along with architectural guidance for cost optimization and performance improvement. The Basic and Developer plans lack phone support and the required response time SLA, while the Enterprise plan offers additional features (e.g., a Technical Account Manager) that are not needed here, making it more expensive than necessary.

Exam trap

The trap here is that candidates often confuse the Developer Support plan's email-only support with phone access, or assume that the Basic plan includes any form of technical support beyond community forums, leading them to overlook the specific response time and channel requirements.

Why the other options are wrong

A

Basic Support does not provide phone or email support with a response time of less than 1 hour for critical failures, nor does it include architectural guidance for cost optimization and performance improvement.

B

Developer Support does not include phone access or a response time of less than 1 hour for critical failures; it only provides email support with a response time of less than 12 hours for critical cases.

D

Enterprise Support is more expensive than Business Support and includes features like a Technical Account Manager and 15-minute response time for critical cases, which are not required by the question. The question asks for the most cost-effective plan that meets the stated needs, and Business Support satisfies all requirements at a lower cost.

107
MCQmedium

A company uses multiple AWS accounts and wants to perform detailed custom cost analysis using a third-party business intelligence (BI) tool. The company needs the most granular cost and usage data available, including resource-level details such as instance type, region, and tags. The BI tool can read CSV files from an Amazon S3 bucket. The company wants a managed AWS service that automatically exports this detailed data to an S3 bucket on a daily basis with no additional coding. Which AWS service should the company use?

A.AWS Cost Explorer
B.AWS Budgets
C.AWS Cost and Usage Reports
D.AWS Trusted Advisor
AnswerC

AWS Cost and Usage Reports (CUR) publishes the most granular cost and usage data, including resource-level details, to an S3 bucket in CSV format on a daily basis. This data can be ingested by third-party BI tools for custom analysis.

Why this answer

AWS Cost and Usage Reports (CUR) is the correct choice because it is a managed AWS service that automatically publishes the most granular cost and usage data—including resource-level details like instance type, region, and tags—to an Amazon S3 bucket in CSV format on a daily basis, with no additional coding required. This directly meets the company's need for detailed custom cost analysis using a third-party BI tool that reads CSV files from S3.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer's manual CSV export capability with the fully automated, scheduled export feature of AWS Cost and Usage Reports, leading them to incorrectly select Cost Explorer.

Why the other options are wrong

A

AWS Cost Explorer provides cost and usage data but does not automatically export CSV files to an S3 bucket on a daily basis; it offers an API and console views, not a managed export to S3 without coding.

D

AWS Trusted Advisor provides recommendations for cost optimization, performance, security, and fault tolerance, but it does not export detailed cost and usage data to S3 for custom analysis with a BI tool.

108
MCQmedium

A company archives historical transaction records in Amazon S3. The records are accessed frequently for the first 30 days after creation. After 30 days, access drops sharply to only a few times per year, but the company must be able to retrieve any record within 5 minutes if needed. The company wants to minimize storage costs while meeting the retrieval time requirement. Which combination of S3 storage classes should the company use?

A.Use S3 Standard for all data.
B.Use S3 Standard for the first 30 days, then transition to S3 Glacier Flexible Retrieval.
C.Use S3 Standard-IA for the first 30 days, then transition to S3 Glacier Deep Archive.
D.Use S3 One Zone-IA for the first 30 days, then transition to S3 Glacier Deep Archive.
AnswerB

S3 Standard provides low-latency access for the initial frequent access period. After 30 days, transitioning to S3 Glacier Flexible Retrieval reduces storage costs significantly. Although standard retrieval from S3 Glacier Flexible Retrieval takes hours, the company can use expedited retrieval (available as an optional feature) to meet the 5-minute requirement when needed, at an additional cost.

Why this answer

S3 Standard provides low-latency access for the first 30 days when records are frequently accessed, and then lifecycle rules transition the data to S3 Glacier Flexible Retrieval, which offers retrieval times of minutes (typically 1–5 minutes for expedited retrievals) at a much lower storage cost. This combination meets the 5-minute retrieval requirement while minimizing costs for data that is rarely accessed after 30 days.

Exam trap

The trap here is that candidates may confuse S3 Glacier Deep Archive's retrieval time (12–48 hours) with S3 Glacier Flexible Retrieval's faster expedited retrieval (1–5 minutes), leading them to incorrectly choose a cheaper but non-compliant storage class.

Why the other options are wrong

A

S3 Standard is designed for frequent access and does not provide cost savings for data that is rarely accessed after 30 days, leading to higher storage costs than necessary.

C

S3 Glacier Deep Archive has a retrieval time of 12 hours or more, which does not meet the 5-minute retrieval requirement. Additionally, S3 Standard-IA is not cost-effective for the first 30 days of frequent access compared to S3 Standard.

D

S3 One Zone-IA does not provide the required 5-minute retrieval time for infrequently accessed data, and S3 Glacier Deep Archive has a retrieval time of 12 hours or more, failing the 5-minute requirement.

MCQmedium

A company operates multiple AWS accounts for separate departments. The finance team wants to simplify monthly billing by receiving a single consolidated invoice that covers all accounts. Additionally, the company wants to aggregate usage across accounts to qualify for lower volume-based pricing tiers. Which AWS feature should the company enable to meet these requirements?

A.Consolidated billing through AWS Organizations
B.AWS Cost Explorer
C.AWS Budgets
D.AWS Trusted Advisor
AnswerA

Consolidated billing through AWS Organizations is a central billing feature that aggregates usage and costs from all member accounts into a single invoice for the management account. This structure directly satisfies the requirement for a single monthly bill while also combining usage across accounts, which allows the organization to qualify for volume-based discounts and reserved capacity pricing tiers. Because it is built into AWS Organizations, it also provides centralized governance and cost visibility without requiring separate tools.

Why this answer

AWS Organizations enables consolidated billing by allowing you to combine multiple AWS accounts under a single paying account, which aggregates usage across all accounts. This aggregation qualifies the company for lower volume-based pricing tiers (e.g., AWS volume discounts for services like S3 or EC2) because usage is summed across all member accounts. The master account receives a single consolidated invoice covering all accounts, simplifying monthly billing.

Exam trap

The trap here is that candidates may confuse AWS Cost Explorer or AWS Budgets with billing consolidation features, but neither of those tools actually aggregates usage across accounts or generates a single invoice; they are monitoring and alerting tools, not billing consolidation services.

Why the other options are wrong

B

AWS Cost Explorer provides visualization and analysis of costs and usage, but it does not consolidate billing across multiple accounts or enable aggregated usage for volume pricing tiers.

C

AWS Budgets allows you to set custom cost and usage budgets and receive alerts when thresholds are exceeded, but it does not provide consolidated billing or aggregated usage across multiple accounts for volume pricing discounts.

D

AWS Trusted Advisor provides recommendations for cost optimization, security, and performance, but it does not consolidate billing or aggregate usage across multiple accounts for volume pricing tiers.

Correct. AWS Cost Explorer is a managed service that provides a graphical interface to view and analyze historical cost and usage data. It also includes a forecasting feature to predict future costs, all without requiring any additional setup or third-party tools.

Why this answer

AWS Cost Explorer provides a pre-built, managed graphical dashboard that visualizes historical spending trends and generates cost forecasts for the next month without requiring any data export or third-party tools. It allows filtering by time range (e.g., past 6 months) and automatically computes a forecast based on historical usage patterns using AWS's internal machine learning models.

Exam trap

The trap here is that candidates often confuse AWS Budgets (which only alerts on thresholds) with Cost Explorer (which provides historical visualization and forecasting), or they assume the Cost and Usage Report includes a built-in dashboard when it actually only provides raw data for external tools.

Why the other options are wrong

B

AWS Budgets allows you to set cost and usage budgets and receive alerts, but it does not provide a graphical dashboard of historical spending trends or cost forecasting.

C

AWS Cost and Usage Report (CUR) provides detailed cost and usage data but does not offer built-in graphical dashboards or forecasting. It requires exporting data to another tool (e.g., Amazon QuickSight) for visualization and forecasting, which contradicts the requirement for an AWS managed service without additional tools.

D

AWS Trusted Advisor provides cost optimization recommendations and checks, but does not offer a graphical dashboard of monthly spending trends or cost forecasting. It is not designed for visualizing historical spending or predicting future costs.

MCQeasy

A company operates three separate AWS accounts: development, testing, and production. Each account independently incurs Amazon S3 data transfer charges. The company signs up for AWS Organizations and enables consolidated billing. How does consolidated billing affect the S3 data transfer pricing for the company?

A.It applies a flat 20% discount to all S3 data transfer charges across accounts.
B.It aggregates the data transfer usage across all accounts, allowing the company to benefit from lower pricing tiers that are based on total usage.
C.It allows the company to use a single payment method and automatically applies Reserved Instance pricing to data transfer.
D.It creates a single combined bill and automatically applies an enterprise discount negotiated with AWS.
AnswerB

This is correct. With consolidated billing, the data transfer usage from all accounts is summed. AWS's pricing tiers (e.g., up to 10 TB, next 40 TB, etc.) are then applied to the aggregate total, often resulting in a lower effective per-GB cost than if each account were billed separately.

Why this answer

Consolidated billing in AWS Organizations aggregates usage across all linked accounts. For S3 data transfer, AWS applies tiered pricing based on total monthly data transfer volume. By combining usage from the development, testing, and production accounts, the company can reach higher volume tiers, reducing the per-GB cost for all accounts.

This is the primary benefit of consolidated billing for data transfer charges.

Exam trap

The trap here is that candidates may assume consolidated billing only simplifies payment or applies a flat discount, rather than understanding it aggregates usage to unlock higher volume pricing tiers.

Why the other options are wrong

A

Consolidated billing does not apply a flat discount; it aggregates usage across accounts to qualify for volume pricing tiers, not a fixed percentage discount.

C

Consolidated billing aggregates usage for data transfer pricing tiers but does not automatically apply Reserved Instance pricing to data transfer; Reserved Instances apply to compute or database services, not to S3 data transfer.

D

Consolidated billing does not automatically apply enterprise discounts; discounts must be negotiated separately and applied at the account or organization level, not automatically via consolidated billing.

MCQmedium

A company runs a batch processing workload on Amazon EC2 instances. The finance team has set a monthly budget of $10,000 for this workload. They want to automatically stop the batch processing instances if the accumulated costs for the month exceed $8,000, to prevent overspending. The company needs a native AWS solution that can monitor the costs and take corrective action automatically. Which AWS feature should the company use to meet these requirements?

A.AWS Budgets with budget actions configured to stop EC2 instances
B.AWS Cost Explorer with a custom cost threshold report
C.AWS Trusted Advisor with a cost optimization check
D.AWS Organizations with a service control policy (SCP)
AnswerA

Correct. AWS Budgets allows you to define cost or usage budgets and set budget actions that trigger automatically when a threshold is exceeded. For example, you can stop EC2 instances to prevent further spending. This meets the requirement natively.

Why this answer

AWS Budgets allows you to set a cost budget of $8,000 and attach a budget action that triggers an AWS Systems Manager (SSM) automation document to stop EC2 instances when actual or forecasted costs exceed the threshold. This provides a native, automated, and serverless solution to enforce cost controls without manual intervention.

Exam trap

The trap here is that candidates may confuse AWS Cost Explorer's reporting capabilities with automated remediation, or assume Trusted Advisor can take corrective actions, when in fact only AWS Budgets with budget actions provides native, automated cost-based instance control.

Why the other options are wrong

B

AWS Cost Explorer provides cost visualization and analysis but does not support automated actions like stopping EC2 instances based on cost thresholds.

C

AWS Trusted Advisor provides cost optimization recommendations but does not offer automated corrective actions to stop EC2 instances based on cost thresholds.

D

Service control policies (SCPs) in AWS Organizations are used to manage permissions across accounts, not to monitor costs or trigger actions based on budget thresholds. They cannot automatically stop EC2 instances when costs exceed a limit.

MCQmedium

A company manages multiple AWS accounts under AWS Organizations. The finance team needs to set a monthly spending limit for each account, receive automatic email alerts when spending reaches 80% of that limit, and also view a graphical dashboard showing historical cost trends across all accounts. Which combination of AWS services should the company use to meet these requirements?

A.AWS Budgets and Amazon QuickSight
B.AWS Cost Explorer and Amazon CloudWatch
C.AWS Cost Explorer and AWS Trusted Advisor
D.AWS Budgets and AWS Cost Explorer
AnswerD

AWS Budgets enables you to define monthly spending limits for each account (or the whole organization) and receive automatic email or SNS alerts when actual or forecasted costs reach a specified percentage of the budget. AWS Cost Explorer provides an intuitive, graphical dashboard that shows historical cost trends across all linked accounts, giving the finance team the visibility they need. This combination directly addresses both requirements without additional overhead.

Why this answer

AWS Budgets allows you to set custom monthly spending limits per AWS account and configure alerts (via Amazon SNS or email) when actual or forecasted costs exceed a threshold, such as 80% of the budget. AWS Cost Explorer provides a graphical dashboard with historical cost trends and enables filtering by linked accounts, making it the correct service for visualizing trends across all accounts under AWS Organizations. Together, they satisfy the requirements for per-account limits, email alerts at 80%, and a historical cost dashboard.

Exam trap

The trap here is that candidates often confuse AWS Budgets with AWS Cost Explorer, thinking Cost Explorer alone can send alerts, or they mistakenly pair Budgets with QuickSight because both involve dashboards, but QuickSight is not the native cost visualization tool for AWS billing data.

Why the other options are wrong

A

AWS Budgets can send alerts, but Amazon QuickSight is a business analytics service for interactive dashboards, not for viewing historical cost trends across accounts. AWS Cost Explorer provides the graphical dashboard for cost trends, so QuickSight is unnecessary and adds cost/complexity.

B

AWS Cost Explorer provides cost visualization and historical trends, but Amazon CloudWatch does not offer budget alerts with spending limits or automatic email notifications at a specific threshold like 80%.

C

AWS Trusted Advisor provides cost optimization recommendations but does not support setting spending limits, sending alerts at a custom threshold, or displaying historical cost trends across accounts.

MCQmedium

A company has unused Reserved Instances that don't match their current infrastructure. What option allows them to recoup some cost from unused RIs?

A.Convert them to Spot Instances
B.Sell them on the Reserved Instance Marketplace
C.Request a refund from AWS for unused RI capacity
D.Transfer them to another AWS account for free
AnswerB

Standard Reserved Instances with at least one month remaining in the term can be listed on the Reserved Instance Marketplace, where other AWS customers can buy the remaining time at the price you set. AWS handles the listing and billing, deducts a service fee from the purchase amount, and gives the proceeds to you. This is the intended mechanism for disposing of an RI you no longer need; Convertible RIs cannot be sold this way.

Why this answer

The AWS Reserved Instance Marketplace allows customers to sell unused Reserved Instances (RIs) to other AWS users, enabling them to recoup some of the upfront costs. This is the only option that directly addresses the need to recover costs from RIs that no longer match the current infrastructure, as AWS does not offer refunds or free transfers for unused RIs.

Exam trap

The trap here is that candidates may assume AWS offers refunds or free transfers for unused RIs, but the only cost-recovery option is selling them on the Reserved Instance Marketplace, which involves a marketplace fee and is subject to availability of buyers.

How to eliminate wrong answers

Option A is wrong because Spot Instances are a separate pricing model for spare compute capacity, not a mechanism to convert or sell existing Reserved Instances; you cannot convert an RI into a Spot Instance. Option C is wrong because AWS does not provide refunds for unused Reserved Instance capacity; RIs are a commitment-based pricing model with no partial refunds for unused time. Option D is wrong because transferring RIs to another AWS account is not free; it requires selling them on the Reserved Instance Marketplace, which involves a transaction fee and is not a direct free transfer.

MCQmedium

A company uses AWS Organizations with consolidated billing across multiple member accounts. The finance team requires that only the management account (payer account) can view and modify payment methods and receive invoices. Member accounts must be prevented from accessing billing and payment information in the AWS Billing and Cost Management console. Which AWS feature should be configured to enforce this restriction?

A.Enable all features in AWS Organizations, including consolidated billing.
B.Apply a Service Control Policy (SCP) to deny billing-related actions for all member accounts.
C.Enable AWS CloudTrail to log billing events for all accounts.
D.Configure AWS Cost Explorer to grant cross-account access only to the management account.
AnswerB

An SCP applied at the root, OU, or member-account level is a preventive control that explicitly denies billing-related IAM actions, such as aws-portal:ViewBilling and aws-portal:ModifyBilling, for all principals in member accounts. Because SCPs filter permissions granted by IAM policies, even an administrator with Allow on its role cannot bypass the deny unless the management account removes the SCP. This leaves full control of consolidated billing, payment methods, and cost data to the management account while blocking member-account users from viewing or changing billing information.

Why this answer

Service Control Policies (SCPs) in AWS Organizations allow you to centrally restrict the AWS services and actions that member accounts can use. By applying an SCP that denies billing-related actions (e.g., `aws-portal:*` or `awsbilling:*`) to all member accounts, the management account can enforce that only the payer account can view and modify payment methods and receive invoices. This directly meets the requirement without affecting the management account, which is not subject to SCPs.

Exam trap

The trap here is that candidates often confuse enabling consolidated billing (Option A) with actually restricting access, not realizing that consolidated billing alone does not enforce any access controls on member accounts.

Why the other options are wrong

A

Enabling all features in AWS Organizations, including consolidated billing, does not by itself restrict member accounts from accessing billing information; it only enables centralized management and consolidated billing features.

C

AWS CloudTrail logs API activity but does not enforce access restrictions; it only provides auditing, not prevention of billing access.

D

AWS Cost Explorer is a tool for visualizing and managing costs, not for controlling access to billing and payment information. It does not prevent member accounts from accessing billing details.

A company runs a mix of production and non-production Amazon EC2 instances. The finance team uses AWS Budgets to monitor monthly spending. For the development accounts, the team wants to automatically stop all running EC2 instances when the account's monthly spending reaches 90% of the budgeted amount. The team wants a solution that does not require custom scripting or additional infrastructure. Which AWS Budgets feature should the team configure to meet this requirement?

A.Create a budget alert that sends an email notification to the operations team when spending reaches 90% of the budget.
B.Configure a budget action that applies an IAM policy to deny the ec2:StopInstances permission for all users.
C.Configure a budget action that runs an AWS Systems Manager automation document to stop the EC2 instances.
D.Create a budget alert that publishes a message to an Amazon Simple Notification Service (Amazon SNS) topic, and subscribe an AWS Lambda function to stop the instances.
AnswerC

AWS Budgets actions can invoke a Systems Manager Automation document such as the pre-defined AWS-StopEC2Instance, which natively stops the specified EC2 instances when the budget threshold is exceeded. This integrates directly with the budget's IAM service role, requiring no custom Lambda functions or manual intervention, and provides a fully managed, serverless automation path for cost governance.

Why this answer

AWS Budgets supports budget actions that can automatically trigger AWS Systems Manager automation documents to stop EC2 instances when a budget threshold is exceeded. This meets the requirement of no custom scripting or additional infrastructure, as the automation document is a built-in capability of Systems Manager.

Exam trap

The trap here is that candidates may choose Option D (Lambda + SNS) because it is a common pattern for automation, but the question explicitly requires 'no custom scripting or additional infrastructure,' making the built-in budget action with Systems Manager the correct choice.

Why the other options are wrong

A

The requirement is to automatically stop EC2 instances when spending reaches 90% of the budget, not just send a notification. Option A only sends an email alert, which requires manual intervention to stop instances, and does not meet the automation requirement.

B

Denying the ec2:StopInstances permission prevents users from stopping instances manually, but does not automatically stop instances when spending reaches 90% of the budget. The requirement is to automatically stop instances, not to restrict user actions.

D

The question explicitly requires a solution that does not require custom scripting or additional infrastructure. Option D requires creating a custom Lambda function (scripting) and an SNS topic (additional infrastructure), which violates the constraint.

MCQmedium

A company is planning to migrate its on-premises infrastructure to AWS. The operations team wants to compare the total cost of ownership (TCO) between running workloads on-premises and running them on AWS. They need a tool that can accept details about their current on-premises servers (number of servers, CPU, memory, storage) and produce a detailed report comparing costs over a specified period, including savings from avoided hardware purchases, IT labor, and data center costs. Which AWS tool should the operations team use?

A.AWS Cost Explorer
B.AWS Total Cost of Ownership (TCO) Calculator
C.AWS Pricing Calculator
D.AWS Cost and Usage Report
AnswerB

The AWS TCO Calculator is the correct tool for this scenario. It accepts input about existing on-premises infrastructure and provides a detailed comparison of costs between running on-premises and on AWS, including savings from hardware, labor, and data center expenses. It helps organizations estimate the financial benefits of migration.

Why this answer

The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of running on-premises infrastructure versus AWS. It accepts detailed inputs about existing on-premises servers (such as CPU, memory, and storage) and generates a comprehensive report that includes savings from avoided hardware purchases, IT labor, and data center costs over a user-specified period. This directly matches the operations team's requirement for a detailed TCO comparison.

Exam trap

The trap here is that candidates often confuse the AWS Pricing Calculator (which estimates AWS service costs) with the TCO Calculator (which compares on-premises vs. AWS costs), leading them to select the Pricing Calculator even though it lacks the on-premises input and comparative savings features.

Why the other options are wrong

A

AWS Cost Explorer analyzes historical cost and usage data, but does not accept on-premises server details to compare TCO with AWS. It cannot model future costs or savings from avoided hardware purchases and data center costs.

C

AWS Pricing Calculator estimates costs for AWS services but does not compare on-premises TCO or include savings from avoided hardware purchases, IT labor, and data center costs.

D

AWS Cost and Usage Report provides detailed billing and usage data but does not compare on-premises costs to AWS costs or generate TCO reports.

MCQmedium

A company runs a production web application on a fleet of Amazon EC2 instances. The operations team has observed that most instances have an average CPU utilization below 10% over the past month. They want to receive automated, ML-based recommendations for downsizing these instances to smaller instance types to reduce costs without compromising performance. The team also wants to see the estimated monthly savings for each recommendation. Which AWS service should the operations team use?

A.AWS Trusted Advisor
B.AWS Cost Explorer
C.AWS Compute Optimizer
D.AWS Budgets
AnswerC

AWS Compute Optimizer applies machine learning to analyze historical utilization metrics—CPU, memory, EBS I/O, and network—for each EC2 instance, then recommends the most cost-efficient instance type and size, including downsizing opportunities. It delivers per-instance findings with projected monthly savings and expected performance impact, making it the only option here that directly performs ML-based right-sizing for production workloads.

Why this answer

AWS Compute Optimizer is the correct service because it uses machine learning to analyze historical utilization metrics (such as CPU, memory, and network) of EC2 instances and provides actionable recommendations to downsize or rightsize instances. It specifically generates estimated monthly savings for each recommendation, directly addressing the need for automated, ML-based downsizing suggestions without compromising performance.

Exam trap

The trap here is that candidates often confuse AWS Trusted Advisor's cost optimization checks with the ML-driven rightsizing capabilities of AWS Compute Optimizer, but Trusted Advisor does not provide per-instance, ML-based recommendations with estimated savings.

Why the other options are wrong

A

AWS Trusted Advisor provides general best-practice checks, including cost optimization, but it does not offer ML-based recommendations for downsizing EC2 instances based on historical utilization patterns.

B

AWS Cost Explorer provides cost and usage data but does not generate ML-based recommendations for downsizing EC2 instances. It lacks the automated, performance-aware optimization logic needed for this scenario.

D

AWS Budgets allows you to set custom cost and usage budgets and receive alerts when you exceed thresholds, but it does not provide ML-based recommendations for downsizing EC2 instances or estimate savings from specific instance changes.

A company runs a production web application on Amazon EC2 and Amazon RDS. The internal IT team needs a support plan that provides a guaranteed response time of less than one hour for a production system outage. Additionally, the company wants access to AWS Infrastructure Event Management, which includes guidance from AWS experts during planned events such as product launches or migrations. The company does not require a dedicated Technical Account Manager (TAM). Which AWS Support plan should the company choose?

A.Basic Support
B.Developer Support
C.Business Support
D.Enterprise Support
AnswerC

Correct. Business Support provides a 1-hour response time for Severity 1 (production system down) cases and includes access to Infrastructure Event Management. It meets the stated requirements without the higher cost and TAM of Enterprise Support.

Why this answer

The Business Support plan is the correct choice because it provides a guaranteed response time of less than one hour for production system outages (production system impaired) and includes access to AWS Infrastructure Event Management for guidance during planned events. The company does not need a dedicated Technical Account Manager (TAM), which is only available with the Enterprise Support plan, making Business Support the most cost-effective option that meets all stated requirements.

Exam trap

The trap here is that candidates often confuse the Developer Support plan's 12-hour response time for production outages with the 1-hour response time offered by Business Support, or mistakenly think that Infrastructure Event Management is available on Developer Support, when it is only available on Business and Enterprise tiers.

Why the other options are wrong

A

Basic Support does not provide a guaranteed response time of less than one hour for production system outages, nor does it include AWS Infrastructure Event Management. It only offers basic account and billing support with no technical support for production issues.

B

Developer Support does not include AWS Infrastructure Event Management and has a maximum response time of 12 hours for system impairment, not under 1 hour for production outages.

D

Enterprise Support includes a dedicated Technical Account Manager (TAM), which the company does not require, and is more expensive than necessary for the stated needs.

A company wants to proactively monitor its AWS spending and receive email notifications when actual or forecasted costs exceed a defined threshold. The company has a monthly budget of $10,000 and wants to be alerted when costs reach 80% of the budget. Which AWS service should the company use to meet these requirements?

A.AWS Cost Explorer
B.AWS Budgets
C.AWS Trusted Advisor
D.AWS Consolidated Billing
AnswerB

AWS Budgets is the correct service because it enables you to set custom cost and usage budgets and define threshold alerts that trigger email notifications (or actions via Amazon SNS) when actual or forecasted costs exceed specified percentages of the budget. This directly meets the requirement for proactive monitoring and alerts at the 80% threshold.

Why this answer

AWS Budgets allows you to set custom cost and usage budgets, and configure alerts that trigger when actual or forecasted costs exceed a defined threshold (e.g., 80% of a $10,000 monthly budget). It can send email notifications via Amazon SNS when the threshold is breached, meeting the proactive monitoring requirement.

Exam trap

The trap here is that candidates confuse AWS Cost Explorer's forecasting capability with proactive alerting, but Cost Explorer does not send automatic notifications; AWS Budgets is the service designed specifically for threshold-based alerts.

Why the other options are wrong

C

AWS Trusted Advisor provides recommendations for cost optimization, security, and performance, but it does not support proactive budget alerts or threshold-based notifications for actual or forecasted costs.

D

AWS Consolidated Billing is a feature for combining multiple accounts into a single payment method, not for setting cost thresholds or sending alerts. It does not provide proactive monitoring or email notifications based on budget percentages.

Which AWS offering provides free, self-paced online training courses, videos, and labs to help customers learn AWS services and pass certification exams?

A.AWS Partner Network (APN)
B.AWS Skill Builder
C.AWS Certification
D.AWS Marketplace
AnswerB

AWS Skill Builder is AWS's official digital learning platform that provides self-paced digital courses, hands-on labs, learning plans, and practice exams. It offers both free and paid subscription tiers, allowing individuals to build practical AWS skills and validate exam readiness. This makes it the correct choice for an individual training platform.

Why this answer

AWS Skill Builder is the official AWS training portal that offers free, self-paced online training courses, videos, and hands-on labs. It is specifically designed to help individuals learn AWS services and prepare for AWS Certification exams, including the CLF-C02. Unlike other options, Skill Builder directly provides the described learning resources at no cost.

Exam trap

The trap here is that candidates may confuse AWS Certification (the exam itself) with the training resources needed to prepare for it, leading them to select option C instead of recognizing that AWS Skill Builder is the dedicated training platform.

How to eliminate wrong answers

Option A is wrong because AWS Partner Network (APN) is a program for organizations and consultants who build solutions on AWS, providing business, technical, and marketing support, but it does not offer free self-paced training courses and labs for individual learners. Option C is wrong because AWS Certification is the credentialing program that validates cloud expertise through exams; it does not itself provide training content, videos, or labs. Option D is wrong because AWS Marketplace is a digital catalog of third-party software and services that run on AWS, not a training platform for learning AWS services or preparing for certifications.

MCQeasy

A company runs non-critical batch analytics jobs that can be paused and restarted if interrupted. The jobs are flexible regarding when they run. Which EC2 purchasing option offers the lowest possible cost for this workload?

A.On-Demand Instances
B.Reserved Instances
C.Spot Instances
D.Dedicated Instances
AnswerC

Spot Instances let you bid on unused EC2 capacity that AWS would otherwise leave idle, commonly delivering 60–90% lower hourly costs than On-Demand. AWS can reclaim the instance with a two-minute warning, but because the batch jobs can pause and restart where they left off, this interruption risk is acceptable. By designing the workload with checkpointing and an Auto Scaling group that replenishes interrupted instances, Spot becomes the lowest-cost compute option for this scenario.

Why this answer

Spot Instances offer the lowest possible cost because they use spare AWS EC2 capacity at a steep discount (up to 90% off On-Demand). Since the batch analytics jobs are non-critical, can be paused and restarted, and are flexible regarding when they run, they are an ideal fit for Spot Instances, which can be interrupted with a 2-minute warning when capacity is reclaimed.

Exam trap

The trap here is that candidates often choose Reserved Instances thinking they always provide the best discount, but they fail to recognize that Spot Instances can be even cheaper for fault-tolerant, flexible workloads that can handle interruptions.

How to eliminate wrong answers

Option A is wrong because On-Demand Instances provide full pricing flexibility but at the highest per-hour cost, making them unsuitable for minimizing costs. Option B is wrong because Reserved Instances offer a discount in exchange for a 1- or 3-year commitment, which is unnecessary for flexible, interruptible workloads and does not achieve the lowest possible cost. Option D is wrong because Dedicated Instances are physically isolated at the host hardware level and incur additional charges, making them the most expensive option for this use case.

A company runs multiple workloads on AWS, each in separate AWS accounts managed through AWS Organizations. The finance team wants to set a monthly cost threshold of $5,000 for the 'development' account. If the actual or forecasted costs exceed 80% of this threshold, the team wants to receive an email alert so they can review usage and take corrective action if needed. They also want to track costs against this threshold over time using a dashboard. Which AWS service should the finance team use to set up this threshold and receive the alerts?

A.AWS Cost Explorer
B.AWS Budgets
C.AWS Trusted Advisor
D.AWS Organizations
AnswerB

AWS Budgets enables you to set custom cost and usage budgets and receive alerts when actual or forecasted costs exceed your defined thresholds. You can also track budget progress on the AWS Budgets dashboard. This matches the requirement perfectly.

Why this answer

AWS Budgets allows you to set custom cost and usage budgets with alerts based on actual or forecasted costs. In this scenario, you can create a budget for the 'development' account with a $5,000 monthly threshold and configure an alert at 80% ($4,000) to send an email notification. AWS Budgets also integrates with Amazon QuickSight or Cost Explorer for historical tracking, but the budget itself provides a dashboard view of current and forecasted spend against the threshold.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer's visualization capabilities with the proactive alerting and threshold-setting functionality that only AWS Budgets provides, leading them to choose Cost Explorer for a task it cannot perform.

Why the other options are wrong

A

AWS Cost Explorer provides visualization and analysis of costs and usage but does not support setting cost thresholds or sending proactive alerts when costs exceed a defined limit.

C

AWS Trusted Advisor provides cost optimization recommendations and checks, but it does not allow setting custom cost thresholds or sending alerts when actual or forecasted costs exceed a specific amount. The question requires a service that can set a $5,000 monthly threshold and send alerts at 80% usage, which is a budgeting and alerting feature, not a recommendation feature.

D

AWS Organizations is a service for centrally managing multiple AWS accounts, not for setting cost thresholds or sending alerts. It does not provide budget tracking or notification capabilities.

A company runs a production application on a mix of Amazon EC2 instance families (e.g., M5, C5, R5) across two AWS Regions. The application runs 24/7 and is expected to continue for the next three years. The company wants to minimize compute costs while retaining the flexibility to change instance families, sizes, or Regions if needed. The company also prefers to avoid any upfront payment to preserve cash flow. Which AWS pricing option should the company choose?

A.On-Demand instances
B.Standard Reserved Instances (no upfront, 3-year term)
C.Compute Savings Plans (no upfront, 3-year term)
D.Spot Instances
AnswerC

Compute Savings Plans offer flexible compute coverage across EC2 instance families, sizes, Regions, OS, and tenancy. The 3-year term with no upfront payment provides cost savings without an initial cash outlay, exactly meeting the stated needs.

Why this answer

Compute Savings Plans (no upfront, 3-year term) provide the highest discount (up to 66%) while allowing flexibility to change instance families (e.g., M5 to C5), sizes, and AWS Regions. This matches the company’s requirement to minimize costs over three years without upfront payment, and the plan automatically applies to any EC2 instance usage within the chosen commitment, preserving the ability to switch instance types or Regions as needed.

Exam trap

The trap here is that candidates often confuse Reserved Instances with Savings Plans, assuming RIs offer the same flexibility, but Standard RIs are region- and instance-family-specific, while Compute Savings Plans provide cross-family and cross-Region flexibility.

Why the other options are wrong

A

On-Demand instances are the most expensive pricing model, and the company wants to minimize costs for a predictable 24/7 workload over three years, making them cost-inefficient.

B

Standard Reserved Instances lock the company to specific instance families and Regions, which conflicts with the requirement to retain flexibility to change instance families, sizes, or Regions.

D

Spot Instances can be interrupted with a 2-minute notice, making them unsuitable for a 24/7 production application that requires continuous availability.

A company received an unexpected AWS bill that was much higher than expected. Which AWS service would help them understand which resource or service caused the cost spike?

A.AWS Budgets
B.AWS Cost Explorer
C.AWS Pricing Calculator
D.AWS Trusted Advisor
AnswerB

AWS Cost Explorer is the correct tool because it lets you visualize and analyze your historical AWS usage and costs over time. You can filter and group data by dimensions such as service, linked account, Region, or resource ID, allowing you to identify exactly which service or resource caused an unexpected cost increase. It also supports custom date ranges and daily/level views, making it ideal for root-cause analysis of a billing spike.

Why this answer

AWS Cost Explorer (B) is the correct service because it provides a pre-built dashboard and reports that allow you to visualize, analyze, and drill down into your AWS costs and usage over time. You can filter by service, linked account, region, or resource tags to identify exactly which resource or service caused the unexpected cost spike. AWS Budgets (A) can alert you when costs exceed a threshold, but it does not provide the historical analysis and granular breakdown needed to pinpoint the root cause of a past spike.

Exam trap

The trap here is that candidates confuse AWS Budgets (a proactive alerting tool) with AWS Cost Explorer (a reactive analysis tool), mistakenly thinking that setting a budget will help them understand the cause of a past spike, when in fact budgets only alert on future thresholds and do not provide historical drill-down capabilities.

How to eliminate wrong answers

Option A is wrong because AWS Budgets is a proactive alerting tool that notifies you when costs or usage exceed a defined budget threshold, but it does not provide the detailed historical cost and usage analysis needed to investigate a past spike. Option C is wrong because AWS Pricing Calculator is a planning tool used to estimate future costs based on expected usage, not a tool for analyzing actual incurred costs or identifying the source of a past bill increase. Option D is wrong because AWS Trusted Advisor is an advisory service that inspects your AWS environment and makes recommendations for cost optimization, performance, security, and fault tolerance, but it does not provide a granular breakdown of historical cost data by resource or service.

MCQmedium

A company wants to ensure they never spend more than $500 per month on AWS services. Which AWS feature can automatically stop or terminate resources when cost projections reach a threshold?

A.AWS Budgets with budget alerts only
B.AWS Budgets Actions
C.AWS Cost Explorer spending forecasts
D.AWS Service Quotas
AnswerB

AWS Budgets Actions are the correct answer because they enable automated responses to budget threshold breaches, directly controlling spending. You can configure an action to apply an IAM policy that denies further resource access, stop EC2 or RDS instances, or invoke a Lambda function for custom remediation. These actions trigger automatically when the budget exceeds the defined threshold, eliminating the need for human intervention. This is precisely the mechanism that both alerts and automatically enforce cost limits.

Why this answer

AWS Budgets Actions allow you to define cost and usage budgets with automated responses, such as stopping or terminating EC2 instances, when actual or forecasted costs exceed a specified threshold. This directly meets the requirement to enforce a $500 monthly spending limit without manual intervention. Budget alerts alone only notify you; they do not take automated actions.

Exam trap

The trap here is that candidates confuse budget alerts (which only notify) with Budgets Actions (which automate responses), leading them to select Option A because they overlook the requirement for automatic resource termination.

How to eliminate wrong answers

Option A is wrong because AWS Budgets with budget alerts only send notifications (e.g., email or SNS) when costs exceed thresholds, but they cannot automatically stop or terminate resources. Option C is wrong because AWS Cost Explorer spending forecasts provide visual predictions of future costs but have no capability to trigger automated actions on resources. Option D is wrong because AWS Service Quotas manage service limits (e.g., maximum number of instances) and do not monitor or control spending thresholds or terminate resources.

A.The remaining 4 instances are free since the Savings Plan covers all usage
B.The remaining 4 instances are charged at On-Demand rates
C.The remaining 4 instances are charged at Spot Instance rates
D.AWS suspends the 4 excess instances to enforce the Savings Plan limit
AnswerB

Usage that exceeds the hourly commitment of a Savings Plan is automatically charged at regular On-Demand prices. Savings Plans are purely a pricing discount on eligible compute usage up to the committed $/hour, not an allocation of free capacity. Therefore, the four extra instances in this scenario incur On-Demand charges without any penalty, suspension, or special rate.

Why this answer

A Compute Savings Plan applies to any EC2 instance usage up to the committed hourly amount (in this case, equivalent to 6 instances). Usage beyond that commitment is charged at standard On-Demand rates. Therefore, the remaining 4 instances are billed at On-Demand prices because the Savings Plan does not cover usage exceeding the commitment.

Exam trap

The trap here is that candidates often assume a Savings Plan covers all usage or that AWS will automatically adjust pricing or terminate instances to enforce the plan, when in reality AWS simply bills excess usage at On-Demand rates without any service disruption.

How to eliminate wrong answers

Option A is wrong because a Savings Plan does not make all usage free; it only applies a discounted rate up to the committed amount, and any excess usage is charged at On-Demand rates. Option C is wrong because Spot Instance rates are only applicable to Spot Instances, which are not automatically applied to On-Demand instances; the Savings Plan does not convert excess On-Demand instances to Spot pricing. Option D is wrong because AWS does not suspend or terminate instances to enforce a Savings Plan limit; it simply bills any usage beyond the commitment at standard On-Demand rates.

A company has been running multiple workloads on AWS for the past six months. The finance team needs to analyze historical spending to identify month-over-month trends by AWS service and by individual linked accounts. The team requires a graphical, interactive tool that allows them to apply custom date ranges and filters, and view the results as customizable charts and graphs. Which AWS service should the finance team use to meet this requirement?

A.AWS Budgets
B.AWS Cost Explorer
C.AWS Trusted Advisor
D.AWS Consolidated Billing
AnswerB

AWS Cost Explorer provides an intuitive graphical interface to explore and visualize AWS costs and usage over time. You can filter by service, linked account, region, and more, and create custom reports for month-over-month trend analysis. This makes it the correct choice for historical spending analysis.

Why this answer

AWS Cost Explorer provides a graphical interface with pre-built charts and graphs that allow users to visualize historical spending trends. It supports filtering by AWS service and linked accounts, and enables custom date ranges for month-over-month analysis, making it the correct choice for the finance team's requirements.

Exam trap

The trap here is that candidates may confuse AWS Budgets' alerting capabilities with Cost Explorer's analytical features, or assume Trusted Advisor's cost optimization checks include historical trend visualization, when in fact only Cost Explorer provides the required interactive graphical analysis.

Why the other options are wrong

A

AWS Budgets allows you to set cost and usage budgets and receive alerts, but it does not provide a graphical, interactive tool for analyzing historical spending trends with custom date ranges and filters.

C

AWS Trusted Advisor provides recommendations for cost optimization, security, and performance, but it does not offer interactive, customizable charts and graphs for historical spending analysis by service or linked account.

D

AWS Consolidated Billing is a feature that aggregates costs across multiple accounts for billing purposes, but it does not provide graphical, interactive tools for analyzing historical spending trends with custom date ranges and filters.

MCQmedium

A company currently pays $50,000/month for on-premises infrastructure. They project that running the equivalent workload on AWS will cost $35,000/month including all data transfer. What is the annual AWS cost savings?

A.$15,000
B.$180,000
C.$420,000
D.$600,000
AnswerB

To compute annual savings, calculate the monthly difference as $50,000 - $35,000 = $15,000 saved per month by migrating to AWS. Then extrapolate that monthly savings over a full year: $15,000 × 12 = $180,000. This correctly answers the question because cost savings accumulate monthly, and the annual figure directly reflects the total reduction in infrastructure spending over a 12-month period.

Why this answer

The monthly cost savings are $50,000 - $35,000 = $15,000. Annualizing this gives $15,000 × 12 = $180,000. Option B is correct because it correctly multiplies the monthly savings by 12 to compute the annual savings.

Exam trap

The trap here is that candidates often confuse monthly savings with annual savings, or mistakenly calculate the annual cost of one environment instead of the difference, leading them to pick Option A, C, or D.

How to eliminate wrong answers

Option A is wrong because it represents the monthly savings ($15,000) rather than the annual savings, failing to multiply by 12. Option C is wrong because it incorrectly calculates annual savings as $35,000 × 12 = $420,000, which is the annual AWS cost, not the savings. Option D is wrong because it incorrectly calculates annual savings as $50,000 × 12 = $600,000, which is the annual on-premises cost, not the savings.

MCQmedium

A company uses AWS Organizations. The management account receives the consolidated bill. Which statement about Reserved Instance discount sharing in AWS Organizations is correct?

A.Reserved Instance discounts only apply to the account that purchased the RI
B.RI discounts are automatically shared across all member accounts in the organization
C.RI discounts are only shared if the management account explicitly enables sharing for each RI
D.RI discounts cannot be shared across accounts even in an Organization
AnswerB

When consolidated billing is active for an AWS Organizations implementation, RI discounts are shared across every member account automatically, with no per-account or per-RI configuration required. The billing aggregator treats all member account usage as a single pool, applying discounted Reserved Instance hours to whichever account generates matching On-Demand usage, which maximizes overall utilization and lowers the total bill. This is the default behavior for all accounts that are part of the organization, although an administrator can choose to opt specific accounts out if they want to restrict those benefits.

Why this answer

In AWS Organizations, Reserved Instance (RI) discounts are automatically shared across all accounts in the organization, provided the accounts are under the same consolidated billing family and the RIs are in the same AWS region. This means that if one member account purchases an RI, the hourly cost benefit can apply to qualifying usage from any other account in the organization, reducing the overall bill. The management account receives the consolidated bill and can see the aggregated savings, but no explicit sharing configuration is required.

Exam trap

The trap here is that candidates often assume RI discounts are account-specific or require manual sharing, but AWS automatically shares them across all accounts in an organization under consolidated billing, which is a core concept tested in the CLF-C02 exam.

How to eliminate wrong answers

Option A is wrong because RI discounts are not limited to the purchasing account; they are automatically shared across all accounts in the organization under consolidated billing. Option C is wrong because AWS does not require the management account to explicitly enable sharing for each RI; sharing is automatic for all RIs in the organization. Option D is wrong because RI discounts can indeed be shared across accounts within an AWS Organization, which is a key benefit of consolidated billing.

A startup is planning a new web application on AWS. The architecture will use Amazon EC2 for compute, Amazon RDS for the database, and Amazon S3 for static assets. The team needs to estimate the monthly cost of running this application before building it. They want to compare costs across different instance types, regions, and pricing models (On-Demand vs. Reserved Instances), and they also need to account for data transfer costs. Which AWS tool should the team use to create this estimate?

A.AWS Cost Explorer
B.AWS Total Cost of Ownership (TCO) Calculator
C.AWS Budgets
D.AWS Pricing Calculator
AnswerD

The AWS Pricing Calculator enables users to estimate the monthly cost of AWS services by selecting specific configurations (e.g., EC2 instance type, RDS database class, S3 storage class, etc.), regions, and pricing models. It provides a detailed cost breakdown and is the correct tool for pre-deployment cost estimation.

Why this answer

AWS Pricing Calculator (formerly AWS Simple Monthly Calculator) is the correct tool because it allows users to estimate monthly costs by selecting specific EC2 instance types, RDS configurations, S3 storage classes, and data transfer volumes. It supports comparing On-Demand vs. Reserved Instance pricing across different regions, making it ideal for pre-build cost estimation.

Exam trap

The trap here is confusing cost estimation tools (Pricing Calculator) with cost management tools (Cost Explorer, Budgets) or TCO analysis, leading candidates to pick a tool that analyzes past spend rather than future projections.

Why the other options are wrong

A

AWS Cost Explorer analyzes existing costs and usage, but cannot generate cost estimates for planned architectures before deployment.

B

The AWS TCO Calculator compares on-premises costs with AWS, not for estimating costs of a new cloud-native application across instance types, regions, and pricing models.

C

AWS Budgets is used to set cost alerts and monitor spending against budgets, not to create upfront cost estimates for planned architectures.

A company operates a critical e-commerce platform on AWS that generates significant revenue. The management team requires a dedicated Technical Account Manager (TAM) to provide proactive guidance and operational best practices. Additionally, they need the fastest possible response time for critical system failures, targeting a response within 15 minutes. Which AWS Support plan should the company choose?

A.Basic Support
B.Business Support
C.Enterprise On-Ramp Support
D.Enterprise Support
AnswerD

Enterprise Support is correct because it bundles a dedicated Technical Account Manager (TAM) with a 15-minute response-time commitment for business-critical systems. For a company running an e-commerce platform where downtime directly impacts revenue, this plan provides the fastest escalation path and hands-on architectural guidance, ensuring critical incidents are triaged immediately.

Why this answer

The company requires a dedicated Technical Account Manager (TAM) and the fastest possible response time for critical system failures (15-minute response). Only the Enterprise Support plan includes a designated TAM and provides a 15-minute response time for business-critical system failures. The Enterprise On-Ramp Support plan offers a TAM but has a longer 30-minute response time for critical cases, and the Business Support plan does not include a TAM at all.

Exam trap

The trap here is that candidates often confuse Enterprise On-Ramp Support with Enterprise Support, assuming both offer the same response times and TAM access, but Enterprise On-Ramp has a longer 30-minute critical response and a different TAM engagement model.

Why the other options are wrong

A

Basic Support does not include a Technical Account Manager (TAM) and offers only a 24-hour response time for critical system failures, far exceeding the required 15-minute response.

B

Business Support does not include a dedicated Technical Account Manager (TAM) and offers a 1-hour response time for critical system failures, not the required 15 minutes.

C

Enterprise On-Ramp Support provides a Technical Account Manager (TAM) and a 15-minute response time for critical failures, but it is designed for organizations with limited AWS experience or smaller workloads, not for a critical e-commerce platform generating significant revenue that requires the full set of Enterprise Support features.

A company uses multiple AWS accounts and needs to perform granular cost and usage analysis using standard SQL queries. The cloud operations team requires the most detailed data possible, including resource-level attributes such as instance type, usage quantity, and cost allocation tags. This data must be automatically delivered to an Amazon S3 bucket on a daily basis for long-term retention and querying. Which AWS service should the company use to generate this dataset?

A.AWS Cost Explorer
B.AWS Budgets
C.AWS Cost and Usage Report
D.AWS Pricing Calculator
AnswerC

The AWS Cost and Usage Report (CUR) contains the most detailed billing and usage data, including individual resource IDs, tags, and hourly usage. It is delivered to an Amazon S3 bucket in a structured format (CSV or Parquet) and can be queried with Amazon Athena, making it the correct choice for granular SQL-based cost analysis.

Why this answer

AWS Cost and Usage Report (CUR) is the correct choice because it provides the most detailed cost and usage data available, including resource-level attributes like instance type, usage quantity, and cost allocation tags. It can be automatically delivered to an Amazon S3 bucket on a daily basis and supports querying with standard SQL via AWS Athena or Amazon Redshift Spectrum, meeting the requirements for granular analysis and long-term retention.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer's visual analytics with the raw data export capability of CUR, assuming Cost Explorer can provide the same detailed, queryable dataset when it only offers aggregated views.

Why the other options are wrong

D

AWS Pricing Calculator is used for estimating future costs, not for generating detailed historical cost and usage data with resource-level attributes and daily delivery to S3.

A company's IT director wants to present a business case for migrating from on-premises infrastructure to AWS. They need to compare the full cost of running on-premises (hardware, facilities, power, labour) against the cost of running equivalent workloads on AWS. Which AWS tool helps create this comparison?

A.AWS Pricing Calculator
B.AWS Cost Explorer
C.AWS TCO Calculator
D.AWS Budgets
AnswerC

The AWS TCO Calculator is designed specifically for comparing on-premises infrastructure total cost of ownership with equivalent AWS costs. It accounts for hardware, software licenses, facilities, networking, and labour costs.

Why this answer

The AWS TCO (Total Cost of Ownership) Calculator is specifically designed to compare the full costs of running on-premises infrastructure (including hardware, facilities, power, and labor) against the equivalent costs on AWS. It generates a detailed side-by-side cost comparison report, helping IT directors build a business case for migration by quantifying potential savings.

Exam trap

The trap here is that candidates confuse the AWS Pricing Calculator (which only estimates AWS service costs) with the TCO Calculator (which compares on-premises vs. AWS total costs), leading them to select Option A instead of C.

How to eliminate wrong answers

Option A is wrong because the AWS Pricing Calculator estimates the cost of AWS services based on usage inputs, but it does not compare on-premises costs or include facilities, power, or labor expenses. Option B is wrong because AWS Cost Explorer analyzes historical AWS spending and forecasts future costs, but it cannot model on-premises infrastructure costs or perform a TCO comparison. Option D is wrong because AWS Budgets sets custom cost and usage budgets and sends alerts, but it does not provide any cost comparison or TCO analysis between on-premises and AWS environments.

MCQmedium

A company is evaluating a migration of its on-premises virtualized workloads to AWS. The CFO wants to understand the potential cost savings over a three-year period by shifting from capital expenditure (hardware purchases) to operational expenditure (pay-as-you-go). The team needs a tool that can provide a detailed comparison of the total cost of ownership (TCO) for the current on-premises environment versus running the same workloads on AWS, including hardware, software, labor, and facilities costs. Which AWS tool should the team use?

A.AWS Budgets
B.AWS Cost Explorer
C.AWS Total Cost of Ownership (TCO) Calculator
D.AWS Trusted Advisor
AnswerC

The AWS TCO Calculator is designed to compare the total cost of ownership of an existing on-premises environment with AWS, factoring in hardware, software, labor, facilities, and other costs. It produces a detailed report that helps organizations estimate the cost savings of migrating to AWS.

Why this answer

The AWS Total Cost of Ownership (TCO) Calculator is specifically designed to compare the costs of running workloads on-premises versus on AWS. It allows users to input details about their current on-premises infrastructure—including hardware, software, labor, and facilities—and generates a detailed side-by-side cost comparison over a specified period (e.g., three years). This directly addresses the CFO's need to understand potential savings from shifting from capital expenditure (CapEx) to operational expenditure (OpEx).

Exam trap

The trap here is that candidates confuse the TCO Calculator with AWS Cost Explorer, assuming both provide cost comparisons, but Cost Explorer only shows historical AWS spend, not a forward-looking comparison with on-premises costs.

Why the other options are wrong

A

AWS Budgets is used to set custom cost and usage budgets and receive alerts when thresholds are exceeded, not to compare TCO between on-premises and AWS environments.

B

AWS Cost Explorer analyzes historical cost data and forecasts future spending, but it does not compare on-premises TCO with AWS costs or include hardware, software, labor, and facilities costs.

D

AWS Trusted Advisor provides recommendations for cost optimization, security, and performance, but it does not generate a detailed TCO comparison between on-premises and AWS environments, including hardware, software, labor, and facilities costs.

A company uses AWS Organizations with multiple accounts. The finance team needs to generate custom cost and usage reports that include every line item, all user-defined cost allocation tags, and resource-level details. The team also needs the ability to query the data using standard SQL tools for in-depth analysis. Which AWS feature should the team use to meet these requirements?

A.AWS Budgets
B.AWS Cost Explorer
C.AWS Cost and Usage Report
D.AWS Trusted Advisor
AnswerC

AWS Cost and Usage Report (CUR) delivers the most detailed cost and usage data, including all tags and resource-level line items. It can be stored in Amazon S3 and queried with Amazon Athena for SQL-based analysis, making it ideal for custom reporting needs.

Why this answer

The AWS Cost and Usage Report (CUR) is the only AWS feature that provides comprehensive, granular cost and usage data including every line item, all user-defined cost allocation tags, and resource-level details. It delivers this data to an Amazon S3 bucket in a CSV or Parquet format, which can then be queried using standard SQL tools via Amazon Athena or other SQL engines. This directly matches the requirement for custom reports and SQL-based analysis.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer's filtering and grouping capabilities with the raw, line-item export functionality of the Cost and Usage Report, not realizing that Cost Explorer cannot provide every line item with all user-defined tags or support direct SQL querying.

Why the other options are wrong

A

AWS Budgets does not generate custom cost and usage reports with line items, tags, or resource-level details, nor does it support SQL querying. It only provides budget alerts and tracking against set thresholds.

B

AWS Cost Explorer provides visualization and analysis of cost and usage data but does not generate custom reports with every line item, user-defined cost allocation tags, and resource-level details, nor does it support SQL querying.

D

AWS Trusted Advisor does not generate cost and usage reports with line items, cost allocation tags, or resource-level details; it provides best-practice recommendations for cost optimization, security, and performance.

Which AWS Cost Management tool provides daily forecasts and allows customers to track Reserved Instance and Savings Plans utilization and coverage?

A.AWS Pricing Calculator
B.AWS Cost and Usage Report
C.AWS Cost Explorer
D.AWS Budgets
AnswerC

AWS Cost Explorer offers an interactive console with built-in views for daily and monthly cost trends, as well as dedicated reports for Reserved Instance and Savings Plans utilization and coverage. It also provides forecasting and right-sizing recommendations, making it a comprehensive tool for analyzing spending patterns and identifying underutilized resources without requiring custom setup. This combination of pre-built analytics and actionable insights is exactly what the scenario needs.

Why this answer

AWS Cost Explorer provides daily cost and usage forecasts for up to 12 months ahead and includes dedicated views for Reserved Instance (RI) and Savings Plans utilization and coverage. This allows customers to monitor how much of their reserved capacity is being used and whether their commitments are adequately covering actual usage.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer's forecasting and utilization tracking capabilities with AWS Budgets, which only provides alerting based on thresholds, not the detailed utilization and coverage analysis for Reserved Instances and Savings Plans.

How to eliminate wrong answers

Option A is wrong because AWS Pricing Calculator is a tool for estimating future costs based on expected usage, not for tracking actual utilization or providing forecasts of existing Reserved Instance or Savings Plans coverage. Option B is wrong because AWS Cost and Usage Report (CUR) is a detailed, raw data export of cost and usage metrics, but it does not offer built-in daily forecasts or pre-built RI/Savings Plans utilization and coverage dashboards. Option D is wrong because AWS Budgets allows you to set cost and usage thresholds and receive alerts, but it does not provide daily forecasts or track RI/Savings Plans utilization and coverage directly.

MCQmedium

A startup is planning to build and launch a new mobile application on AWS. The team expects very low initial traffic but hopes to scale rapidly. They have a limited budget and want to avoid any upfront costs. They are unsure which AWS services they will need and want to estimate their monthly AWS charges before committing to an architecture. Additionally, they need access to technical support to help troubleshoot issues that arise during development and production, with a guaranteed response time of less than 12 hours for production-impacting issues. Which combination of AWS tool and support plan should the startup choose to meet these requirements?

A.AWS Pricing Calculator + Developer Support
B.AWS Cost Explorer + Basic Support
C.AWS Budgets + Business Support
D.AWS Total Cost of Ownership (TCO) Calculator + Enterprise Support
AnswerA

Correct. The AWS Pricing Calculator lets you estimate monthly costs for AWS services before building the architecture. The Developer Support plan offers a response time of less than 12 hours for production issues that impair the system, which meets the stated requirement. This combination is cost-effective for a startup with limited budget.

Why this answer

The AWS Pricing Calculator allows the startup to estimate monthly costs without any upfront commitment, which aligns with their need to avoid upfront costs and predict charges before architecting. The Developer Support plan provides a response time of less than 12 hours for production-impacting issues (specifically, a response time of 12 hours for impaired production systems under the Developer plan), meeting their support requirement while keeping costs low for a startup with limited budget.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer (a historical analysis tool) with the AWS Pricing Calculator (a future estimation tool), and they may assume Basic Support includes support SLAs when it does not, leading them to choose Option B incorrectly.

Why the other options are wrong

B

AWS Cost Explorer is for analyzing historical costs, not estimating future charges for an unbuilt architecture. Basic Support does not provide a guaranteed response time of less than 12 hours for production-impacting issues.

C

AWS Budgets allows you to set cost alerts but does not provide cost estimation for unknown architectures. Business Support offers 1-hour response for production-impacting issues, but the question requires a guaranteed response time of less than 12 hours, which Developer Support meets (less than 12 hours for production systems impaired).

D

The TCO Calculator compares on-premises vs. cloud costs, not estimating monthly AWS charges for a new architecture. Enterprise Support is overkill and expensive for a startup with limited budget needing <12 hour response for production issues.

MCQmedium

A company runs a production e-commerce application on AWS. The CIO requires that the company have access to AWS technical support with a response time of under 1 hour for critical production system failures. Additionally, the operations team wants to use AWS Trusted Advisor to get recommendations on cost optimization, performance, and security for all AWS resources. The company already pays for AWS Business Support for its development account but wants the minimum-cost support plan that meets these requirements for its production account. Which AWS Support plan should the company choose for the production account?

A.AWS Basic Support
B.AWS Developer Support
C.AWS Business Support
D.AWS Enterprise Support
AnswerC

AWS Business Support provides a 1-hour response time for critical production system failures and includes full access to all AWS Trusted Advisor checks. This matches the company's requirements at a lower cost than Enterprise Support, making it the correct and most cost-effective choice.

Why this answer

AWS Business Support is the minimum plan that provides a 1-hour response time for critical production system failures and full access to AWS Trusted Advisor, including cost optimization, performance, and security checks. AWS Basic and Developer Support do not offer a 1-hour response time for critical failures, and Developer Support only provides limited Trusted Advisor checks. Therefore, Business Support meets both requirements at the lowest cost for the production account.

Exam trap

The trap here is that candidates may assume Developer Support is sufficient because it includes technical support, but they overlook the specific 1-hour response time requirement and the need for full Trusted Advisor recommendations, which only Business Support provides.

Why the other options are wrong

A

AWS Basic Support does not provide technical support with a response time of under 1 hour for critical failures, nor does it include AWS Trusted Advisor recommendations for cost optimization, performance, and security.

B

AWS Developer Support does not include a response time of under 1 hour for critical production failures; it offers only general guidance with a response time of less than 12 hours for critical cases. It also does not provide full access to AWS Trusted Advisor for cost optimization, performance, and security recommendations.

D

Enterprise Support is more expensive than Business Support and includes features like a Technical Account Manager (TAM) and infrastructure event management, which are not required by the question. The minimum-cost plan that meets the requirements (under 1-hour response for critical failures and Trusted Advisor for cost optimization, performance, and security) is Business Support.

142
MCQmedium

A company currently uses the AWS Basic Support plan. The CTO wants to access the complete set of AWS Trusted Advisor checks, including those related to cost optimization and performance. Additionally, the CTO requires a guaranteed response time of less than 15 minutes for critical business-impairing issues. Which AWS Support plan should the company choose to meet all of these requirements?

A.AWS Business Support
B.AWS Developer Support
C.AWS Enterprise Support
D.AWS Basic Support
AnswerC

Enterprise Support provides the full set of Trusted Advisor checks (including cost optimization and performance) and guarantees a response time of under 15 minutes for critical business-impairing issues. This plan meets both requirements stated by the CTO.

Why this answer

The AWS Enterprise Support plan is the only plan that provides a guaranteed response time of less than 15 minutes for critical business-impairing issues. While both the Business and Enterprise Support plans include the full set of Trusted Advisor checks, only Enterprise meets the response time requirement. The Business Support plan offers a 1-hour response time for critical issues.

The Developer Support plan has a 12-hour response time for critical issues and does not include the full set of Trusted Advisor checks. Basic Support has no technical support and limited Trusted Advisor checks.

Exam trap

The trap here is that candidates might think the Business Support plan meets all requirements because it provides the full set of Trusted Advisor checks. However, Business Support only offers a 1-hour response time for critical issues, not the required less than 15 minutes. Only AWS Enterprise Support guarantees a sub-15-minute response for critical issues.

Why the other options are wrong

A

AWS Business Support provides full Trusted Advisor checks and a 15-minute response time for critical issues, but the question requires a guaranteed response time of less than 15 minutes, which is only offered by Enterprise Support (15-minute SLA for business-critical systems).

B

AWS Developer Support does not provide access to the complete set of Trusted Advisor checks (only core checks) and has a response time of less than 12 hours for critical issues, not 15 minutes.

D

AWS Basic Support does not provide access to the complete set of Trusted Advisor checks (only core checks) and offers no guaranteed response times for support cases.

MCQmedium

A company has an AWS Basic Support plan. The operations team wants to use AWS Trusted Advisor to receive recommendations for cost optimization, such as identifying idle load balancers and underutilized Amazon EC2 instances. They log into the AWS Management Console and navigate to Trusted Advisor, but they only see a limited set of checks, such as S3 bucket permissions and service limits. Which action should the team take to access the complete library of Trusted Advisor checks, including the cost optimization recommendations?

A.Enable AWS Config to perform the cost optimization and underutilization checks.
B.Upgrade to a Developer Support plan.
C.Upgrade to a Business or Enterprise Support plan.
D.No action is needed; the full set of Trusted Advisor checks is already available for all AWS Support plans.
AnswerC

The full library of Trusted Advisor checks, which includes cost optimization recommendations (e.g., idle load balancers, underutilized EC2 instances), is available only to customers with a Business or Enterprise Support plan. These plans provide access to all checks across security, cost optimization, performance, and fault tolerance.

Why this answer

AWS Trusted Advisor provides a full set of checks, including cost optimization recommendations (e.g., idle load balancers, underutilized EC2 instances), only to customers with a Business or Enterprise Support plan. The Basic Support plan restricts Trusted Advisor to a limited subset of checks, such as S3 bucket permissions and service limits. Therefore, upgrading to a Business or Enterprise Support plan is required to access the complete library of checks.

Exam trap

The trap here is that candidates often assume AWS Config can perform cost optimization checks similar to Trusted Advisor, or that upgrading to a Developer plan is sufficient, when in fact only Business or Enterprise plans unlock the full Trusted Advisor check library.

Why the other options are wrong

A

AWS Config is a service for resource inventory and configuration history, not for providing Trusted Advisor checks. Trusted Advisor's full set of checks, including cost optimization, requires a Business or Enterprise Support plan.

B

The Developer Support plan does not include the full set of Trusted Advisor checks; only Business and Enterprise Support plans provide access to all checks, including cost optimization recommendations.

D

The AWS Basic Support plan only provides a limited set of Trusted Advisor checks (e.g., S3 bucket permissions and service limits). Cost optimization checks like idle load balancers and underutilized EC2 instances require a Business or Enterprise Support plan.

MCQmedium

A company has committed to a 1-year Compute Savings Plan at $100/hour. During a given hour, their actual compute usage is only worth $80 at On-Demand rates. How does the Savings Plan apply?

A.You pay $80 (actual usage) and the unused $20 commitment carries over to the next hour
B.You pay the committed $100 for the hour, with $20 of the commitment being unused
C.You are refunded the $20 unused portion at end of month
D.You pay $80 discounted at the Savings Plan rate, saving even more than committed
AnswerB

With a Savings Plan, you commit to a specific hourly payment (here, $100) in exchange for discounted rates on eligible usage. Your actual usage for the hour is $80, which is below the commitment, so you are billed the full committed $100 for that hour. The $20 difference is unused capacity and does not roll over or get credited back; it is the cost of the flexibility and discounted pricing the plan provides. This exactly matches the correct behavior described in the question.

Why this answer

With a Compute Savings Plan, you commit to a consistent hourly spend ($100/hour) in exchange for lower compute rates. If your actual usage in an hour is only $80 at On-Demand rates, you still pay the full $100 commitment for that hour; the unused $20 is not refunded or carried over. This is because Savings Plans require you to pay the committed amount regardless of actual usage, ensuring AWS receives the predictable revenue that funds the discount.

Exam trap

The trap here is that candidates assume unused Savings Plan commitment is either refunded or carried over, similar to a prepaid service credit, when in fact it is forfeited per hour, testing your understanding that Savings Plans are a commitment-based discount model, not a usage-based credit.

How to eliminate wrong answers

Option A is wrong because unused commitment does not carry over to the next hour; Savings Plans are measured and billed per hour, and any unused portion is forfeited. Option C is wrong because there is no end-of-month refund for unused Savings Plan commitment; the discount applies only to usage up to the commitment, and unused amounts are not reimbursed. Option D is wrong because the Savings Plan discount applies to the committed amount, not to actual usage; you do not pay a discounted rate on the $80 usage—you pay the full $100 commitment, and the discount reduces the effective rate for usage covered by the plan.

A startup is planning to migrate its web application to AWS. The CTO wants to estimate the monthly cost of running the application on Amazon EC2 and Amazon RDS, including data transfer costs. The team has not yet created any AWS accounts or resources. They need a tool that allows them to input assumptions about instance types, storage, and data transfer to generate a detailed cost estimate. Which AWS tool should they use?

A.AWS Cost Explorer
B.AWS Budgets
C.AWS Pricing Calculator
D.AWS Trusted Advisor
AnswerC

The AWS Pricing Calculator is a free web-based tool that lets you estimate the cost of AWS services based on your specific input parameters, such as instance types, storage, and data transfer. It is ideal for planning a migration before any AWS resources are created.

Why this answer

AWS Pricing Calculator (option C) is the correct tool because it allows users to input assumptions about EC2 instance types, RDS configurations, storage, and data transfer to generate a detailed monthly cost estimate before any AWS resources are created. Unlike Cost Explorer, which requires existing usage data, the Pricing Calculator is designed for upfront cost modeling and planning.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer (which requires existing usage data) with the AWS Pricing Calculator (which is specifically designed for pre-provisioning cost estimation), leading them to select Cost Explorer when no AWS account or resources exist yet.

Why the other options are wrong

A

AWS Cost Explorer analyzes existing costs from past usage, but the startup has no AWS account or resources yet, so there is no historical data to analyze.

B

AWS Budgets is used to set spending limits and receive alerts when costs exceed thresholds, not to generate detailed cost estimates based on assumptions about instance types, storage, and data transfer before creating any resources.

D

AWS Trusted Advisor provides recommendations for cost optimization, performance, security, and fault tolerance, but it does not allow users to input assumptions about instance types, storage, and data transfer to generate a detailed cost estimate before creating resources.

A company needs 24/7 phone and chat access to AWS support engineers, full access to all AWS Trusted Advisor checks, and a response time of less than 1 hour for production system outages. Which is the minimum AWS Support plan that meets all these requirements?

A.Basic Support
B.Developer Support
C.Business Support
D.Enterprise On-Ramp Support
AnswerC

Business Support includes 24/7 phone and chat access, full Trusted Advisor checks, a 1-hour response time for production system down, and access to the AWS Support API. This is the minimum plan meeting all stated requirements.

Why this answer

The Business Support plan is the minimum plan that provides 24/7 phone and chat access to AWS support engineers, full access to all AWS Trusted Advisor checks, and a response time of less than 1 hour for production system outages. The Basic and Developer plans lack 24/7 phone/chat and full Trusted Advisor checks, while the Enterprise On-Ramp plan offers these features but is not the minimum because Business Support already meets all requirements.

Exam trap

The trap here is that candidates often confuse Enterprise On-Ramp Support as the minimum because it includes all features, but the question asks for the 'minimum' plan, and Business Support already satisfies every requirement without the higher cost of Enterprise On-Ramp.

How to eliminate wrong answers

Option A is wrong because Basic Support provides only documentation, whitepapers, and limited Trusted Advisor checks (core checks only), with no phone/chat access or defined response times for production outages. Option B is wrong because Developer Support offers business hours email access only, no 24/7 phone/chat, and limited Trusted Advisor checks (core checks only), with a response time of less than 12 hours for production outages, not under 1 hour. Option D is wrong because Enterprise On-Ramp Support does include 24/7 phone/chat, full Trusted Advisor checks, and a 1-hour response time for production outages, but it is not the minimum plan—Business Support is the lowest tier that provides all these features.

A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?

A.AWS Cost Explorer
B.AWS Budgets
C.AWS Trusted Advisor
D.AWS Organizations
AnswerB

AWS Budgets allows you to set custom cost and usage budgets, define alert thresholds (e.g., at 80% of budget), and automatically send email or SNS notifications when those thresholds are met or exceeded. This meets the requirement without custom code.

Why this answer

AWS Budgets is a managed service that allows you to set custom cost and usage budgets and receive alerts when your actual or forecasted costs exceed (or are forecasted to exceed) your budgeted amount. It can automatically send email notifications at specified thresholds (e.g., 80% and 100%) without requiring any custom code or third-party tools, making it the ideal solution for the finance team's requirements.

Exam trap

The trap here is that candidates often confuse AWS Cost Explorer's cost analysis and forecasting capabilities with automated alerting, but Cost Explorer does not natively send proactive notifications; AWS Budgets is the correct service for threshold-based alerts.

Why the other options are wrong

A

AWS Cost Explorer provides visualization and analysis of cost data but does not automatically send email alerts based on budget thresholds without custom code or third-party tools.

C

AWS Trusted Advisor provides cost optimization recommendations and checks, but it does not natively support setting custom budget thresholds or sending email alerts when costs reach specific percentages of a budget.

D

AWS Organizations is a service for centrally managing multiple AWS accounts and consolidating billing, but it does not natively send budget alerts via email. The question requires a managed service that automatically sends notifications when costs reach thresholds, which is a feature of AWS Budgets, not Organizations.

A company runs a containerized application on Amazon ECS using a mix of Amazon EC2 On-Demand instances from different instance families (e.g., M5, C5, R5). The workload is consistent, and the company is willing to commit to a 1-year term to reduce costs. However, the team expects to change instance families within the next 12 months due to new hardware requirements and wants the flexibility to switch instance families without incurring a financial penalty. Which pricing option best meets these requirements?

A.Compute Savings Plans
B.EC2 Instance Savings Plans
C.Convertible Reserved Instances
D.Standard Reserved Instances
AnswerA

Correct. Compute Savings Plans apply to any EC2 instance usage across any region (when scoped to region), regardless of instance family, and provide the flexibility to change instance families without any penalty, while offering substantial discounts over On-Demand pricing.

Why this answer

Compute Savings Plans provide the most flexibility by applying a discounted hourly commitment (e.g., $10/hour) across any EC2 instance family, region, OS, or tenancy, and also cover Fargate and Lambda usage. Since the company expects to change instance families within the 1-year term, Compute Savings Plans allow switching without penalty, unlike instance-specific plans.

Exam trap

The trap here is that candidates often confuse EC2 Instance Savings Plans with Compute Savings Plans, assuming instance-specific plans offer the same flexibility, but they fail to recognize that only Compute Savings Plans allow family changes without penalty or manual exchange.

Why the other options are wrong

B

EC2 Instance Savings Plans apply to a specific instance family within a region, so changing instance families would incur a penalty or require a new plan, failing the flexibility requirement.

C

Convertible Reserved Instances allow changing instance families but require a 1-year or 3-year commitment and do not offer the flexibility to switch without financial penalty; exchanging instances may result in different pricing terms or fees.

D

Standard Reserved Instances require a 1-year commitment to a specific instance family and region, and switching instance families would incur a financial penalty or require selling the reservation on the Reserved Instance Marketplace, which does not meet the flexibility requirement.

MCQmedium

A company wants to review its AWS spending for the past six months to identify which services and business units are driving costs. The finance team needs to interactively examine cost trends, filter by service and account, and visualize the data without setting up complex reports. Which AWS service or tool should the company use to meet these requirements?

A.AWS Cost Explorer
B.AWS Budgets
C.AWS Trusted Advisor
D.AWS Cost and Usage Reports
AnswerA

AWS Cost Explorer offers a ready-to-use graphical interface to explore and analyze your AWS costs and usage over custom time periods, with filters by service, account, region, and tags. It directly meets the need for interactive trend analysis without requiring additional setup.

Why this answer

AWS Cost Explorer provides a pre-built, interactive dashboard that allows you to visualize and analyze your AWS cost and usage data over the past 12 months. You can filter by service, linked account (business unit), and time range, and drill down into trends without needing to set up complex reports or queries. This directly meets the requirement for interactive examination of cost trends by service and account.

Exam trap

The trap here is that candidates confuse AWS Cost Explorer (interactive visualization) with AWS Cost and Usage Reports (raw data export), assuming both provide the same interactive experience, but CUR requires additional tools like Athena or QuickSight to visualize the data.

Why the other options are wrong

B

AWS Budgets allows you to set cost and usage alerts, but it does not provide interactive visualization or historical trend analysis for the past six months across services and accounts.

C

AWS Trusted Advisor provides best-practice recommendations for cost optimization, but it does not offer interactive cost trend analysis, filtering by service/account, or data visualization; it is not a cost exploration tool.

D

AWS Cost and Usage Reports (CUR) provides detailed, raw cost data but requires setting up Amazon Athena or other tools for interactive querying and visualization, whereas the question explicitly asks for an interactive tool without complex report setup.

A company is deploying a mission-critical application on AWS. The application requires the highest level of support available, including a designated Technical Account Manager (TAM) and a response time of 15 minutes or less for production system down cases. Which AWS Support plan should the company choose?

A.Developer
B.Business
C.Enterprise On-Ramp
D.Enterprise
AnswerD

The AWS Enterprise Support plan is the only tier that includes a designated Technical Account Manager (TAM) as a standard feature, and it guarantees a 15-minute response time for production system down (severity 1) cases. This combination of proactive architectural guidance and the fastest production incident response directly satisfies both the requirement for a TAM and the 15-minute downtime response target. Therefore, for a mission-critical application needing immediate escalation and a named advocate, Enterprise is the correct choice.

Why this answer

The Enterprise support plan is the only AWS Support plan that includes a designated Technical Account Manager (TAM) and a 15-minute response time for production system down cases. The company's requirement for the highest level of support with these specific features directly maps to the Enterprise plan, which is designed for mission-critical workloads.

Exam trap

The trap here is that candidates may confuse the Enterprise On-Ramp plan (which includes a TAM but has a 30-minute response time) with the full Enterprise plan (which has a 15-minute response time), overlooking the specific response time requirement in the question.

Why the other options are wrong

A

The Developer plan does not include a Technical Account Manager (TAM) and offers a maximum response time of 12 hours for general guidance, not 15 minutes for production system down cases.

B

The Business support plan does not include a designated Technical Account Manager (TAM) and offers a 1-hour response time for production system down, not the required 15 minutes.

C

Enterprise On-Ramp does not include a designated Technical Account Manager (TAM) or a 15-minute response time for production system down cases; it offers a 30-minute response time and access to a pool of TAMs.
