CLF-C02 Billing, Pricing, and Support Practice Test 6 — 15 Questions

Question 1

A company has migrated to AWS and uses multiple accounts under AWS Organizations with consolidated billing. The finance team needs a monthly cost breakdown by business unit. Each business unit's AWS resources are tagged with a 'BusinessUnit' tag (e.g., 'Marketing', 'Engineering'). However, some resources are not tagged. The team wants to see both the cost per business unit (based on tagged resources) and the total cost of untagged resources, all in one view. They also need the ability to filter by AWS service (e.g., EC2, S3) for each business unit. Which AWS tool or feature should the finance team use to meet these requirements?

Accepted Answer

AWS Cost Explorer. AWS Cost Explorer provides a customizable dashboard that allows you to filter and group costs by tags (such as 'BusinessUnit') and by AWS service (e.g., EC2, S3). It can display both tagged and untagged resource costs in the same view, enabling the finance team to see a monthly breakdown per business unit alongside the total cost of untagged resources. This meets all the requirements without additional configuration.

Answer

AWS Budgets

Answer

AWS Trusted Advisor

Answer

AWS Monthly Report (from Billing console)

Question 2

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?

Accepted Answer

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.. 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.

Answer

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.

Answer

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.

Answer

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.

Question 3

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?

Accepted Answer

AWS Pricing Calculator. 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.

Question 5

A company runs a production workload on Amazon EC2 instances that must be available continuously. The workload has predictable usage patterns. The company wants to minimize compute costs while maintaining high availability. Which pricing model should they choose?

Accepted Answer

Reserved Instances. Reserved Instances (RIs) are the correct choice because the workload requires continuous availability and has predictable usage patterns. By committing to a 1- or 3-year term, the company can receive a significant discount (up to 72%) compared to On-Demand pricing, while still ensuring the EC2 instances are always running and highly available. This model directly aligns with the need to minimize compute costs for a steady-state, always-on production workload.

Answer

On-Demand Instances

Answer

Spot Instances

Answer

Dedicated Hosts

Question 6

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?

Accepted Answer

Enable Consolidated Billing in AWS Organizations. 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.

Answer

Set up an AWS Budget to track all account costs

Answer

Use Cost Explorer to generate a combined cost report

Answer

Activate AWS Trusted Advisor on the management account

Question 7

A company runs a steady, predictable workload on a diverse mix of Amazon EC2 instances spanning multiple instance families (e.g., M5, C5, R5) and AWS Regions. The company wants to maximize cost savings while retaining the ability to freely change instance families and Regions during the commitment term without losing the discount. Which AWS pricing model should the company use?

Accepted Answer

Compute Savings Plans. Compute Savings Plans (D) offer the highest flexibility by applying a discounted hourly commitment across any EC2 instance family, size, OS, tenancy, and region, automatically covering usage changes without losing the discount. This matches the requirement to freely change instance families and regions during the term while maximizing savings over On-Demand pricing.

Answer

On-Demand Instances

Answer

Reserved Instances

Answer

Spot Instances

Question 8

A company has been running multiple workloads on AWS for over six months. The finance team needs to gain visibility into historical cost and usage data, identify which services are driving the most spend, forecast future monthly costs, and receive recommendations for purchasing Reserved Instances to achieve the highest savings. The team wants to use a native AWS tool that provides this functionality without requiring any third-party software. Which AWS tool should the finance team use?

Accepted Answer

AWS Cost Explorer. AWS Cost Explorer is the correct choice because it provides a native interface for visualizing historical cost and usage data, identifying top spend drivers, forecasting future costs up to 12 months, and generating Reserved Instance (RI) purchase recommendations based on actual usage patterns. It meets all the finance team's requirements without any third-party software.

Question 10

A company manages multiple AWS accounts through AWS Organizations. The finance team wants to receive a consolidated view of costs across all accounts and track costs against a monthly budget of $50,000 for the entire organization. They want to be alerted when actual costs reach 90% of the budget and again when they exceed 100%. Which combination of AWS services should the finance team use?

Accepted Answer

AWS Budgets to create a budget and configure alerts, and AWS Cost Explorer to view consolidated cost data.. AWS Budgets is the correct service for setting a monthly budget of $50,000 and configuring alerts at 90% and 100% thresholds. AWS Cost Explorer provides the consolidated view of costs across all accounts in AWS Organizations. Together, they meet both requirements: Budgets handles the alerting, and Cost Explorer provides the consolidated cost visualization.

Answer

AWS Cost Explorer to create a budget alert and AWS Budgets to view consolidated costs.

Answer

AWS Trusted Advisor to set a cost optimization budget and AWS Cost Explorer to send alerts.

Answer

Question 11

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?

Accepted Answer

AWS Cost and Usage Report. 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.

Question 12

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?

Accepted Answer

Convertible Reserved Instance. 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.

Answer

Standard Reserved Instance

Answer

Compute Savings Plan

Answer

On-Demand

Question 13

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?

Accepted Answer

The Savings Plan must be purchased in the management account, and the discount automatically applies to all accounts in the organization.. 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.

Answer

The Savings Plan must be purchased separately in each account where the discount is needed.

Answer

The finance team must create custom cost allocation tags to distribute the Savings Plan discount across accounts.

Answer

The Savings Plan must be linked to each member account using the AWS Billing Conductor.

Question 14

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?

Accepted Answer

AWS Compute Optimizer. 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.
