CLF-C02 Billing, Pricing, and Support Practice Test 9 — 15 Questions

Question 1

A company runs a set of steady-state workloads on Amazon EC2 instances and Amazon ECS Fargate tasks. The company expects consistent usage for the next 3 years and wants to reduce compute costs. The company prefers flexibility to move workloads between different instance families and across different AWS compute services (EC2, ECS, and Lambda) without committing to a specific instance type or family. Which AWS pricing model meets these requirements?

Accepted Answer

Compute Savings Plans (3-year, partial upfront). Compute Savings Plans (3-year, partial upfront) is correct because it provides the highest flexibility, allowing workloads to move between EC2 instances, ECS Fargate, and Lambda without committing to a specific instance family or compute service. The 3-year term with partial upfront offers the maximum discount (up to 66%) for steady-state workloads while still enabling the required flexibility across compute services. This pricing model automatically applies the lowest price across any region and compute option, making it ideal for the described steady-state but flexible workload.

Answer

Standard Reserved Instances (1-year, all upfront)

Answer

Convertible Reserved Instances (3-year, all upfront)

Question 2

A company runs a variety of workloads on AWS and wants to be notified when their monthly spending behaves unusually compared to past patterns. They want a managed service that uses machine learning to detect cost anomalies and provides root cause analysis. Which AWS service or feature should they use?

Accepted Answer

AWS Cost Anomaly Detection. AWS Cost Anomaly Detection is a managed service that leverages machine learning to continuously monitor your cost and usage patterns, detect anomalies, and provide root cause analysis. It automatically establishes a baseline from historical spending data and alerts you when actual spending deviates from expected patterns, making it the correct choice for this use case.

Question 4

A company uses multiple AWS accounts and wants to enforce cost governance. The company needs to set a monthly cost budget of $10,000 for each account. When an account's actual or forecasted costs exceed this budget, the company wants to automatically apply a restrictive IAM policy that prevents the creation of new resources in that account. Additionally, the company wants to receive an email notification when the budget is exceeded. Which AWS feature should the company use to meet these requirements?

Accepted Answer

AWS Budgets. AWS Budgets allows you to set custom cost and usage budgets, and when actual or forecasted costs exceed the budget threshold, it can trigger actions such as applying an IAM policy to restrict resource creation and sending SNS-based email notifications. This directly meets the requirement for automated enforcement and alerting per account.

Question 5

A company manages multiple AWS accounts using AWS Organizations with consolidated billing. The company purchases a Standard Reserved Instance (RI) for an Amazon EC2 m5.large instance in a member account (the production account). The finance team wants the discount from this RI to apply to any m5.large instance usage across all accounts in the organization. What must the company do to achieve this?

Accepted Answer

Enable Reserved Instance sharing in the AWS Management Console under the Billing and Cost Management service.. Option B is correct because in AWS Organizations with consolidated billing, Reserved Instance discounts can be shared across all accounts in the organization only if the 'RI sharing' feature is explicitly enabled in the Billing and Cost Management console. By default, RIs are scoped to the account that purchased them; enabling sharing allows the discount to apply to matching usage in any member account.

Answer

Set the 'shared' attribute to 'true' when purchasing the Reserved Instance.

Answer

Enable the Reserved Instance sharing setting in the AWS Organizations console.

Answer

No action is needed; all Reserved Instances purchased in any account within a consolidated billing environment automatically apply across all member accounts.

Question 6

A company plans to migrate a three-tier web application to AWS. The application will run on Amazon EC2 instances, use an Amazon RDS database, and an Application Load Balancer. The CFO needs a detailed monthly cost estimate before migration. The solutions architect needs to model different instance types, storage sizes, and data transfer volumes, and then share the estimate with the finance team. Which AWS service should the solutions architect use to meet these requirements?

Accepted Answer

AWS Pricing Calculator. AWS Pricing Calculator allows the solutions architect to model different EC2 instance types, RDS storage sizes, and data transfer volumes to generate a detailed monthly cost estimate. It provides granular control over pricing assumptions, including reserved vs. on-demand instances, and produces a shareable estimate link for the finance team. This makes it the correct tool for pre-migration cost modeling.

Question 7

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?

Accepted Answer

AWS Cost and Usage Reports. 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.

Question 8

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?

Accepted Answer

Activate the cost allocation tags in the Billing and Cost Management console.. 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.

Answer

Enable detailed billing reports in the Billing console.

Answer

Create a budget in AWS Budgets and set tag-based filters.

Answer

Use AWS Organizations to create separate accounts per project.

Question 9

A company runs 200 Amazon EC2 instances for its web application. The finance team wants to identify instances that are over-provisioned or underutilized to reduce costs. The team needs automated recommendations that consider the instance's CPU, memory, and network utilization patterns over the past 14 days. Which AWS service should the team use?

Accepted Answer

AWS Compute Optimizer. AWS Compute Optimizer is the correct service because it uses machine learning to analyze historical utilization metrics (CPU, memory, network) over a specified lookback period (up to 93 days, but 14 days is supported) and generates actionable recommendations to right-size EC2 instances. It specifically identifies over-provisioned and underutilized instances, directly addressing the finance team's cost-reduction goal with automated, metric-driven insights.

Question 10

A company runs a mix of Amazon EC2 instances, AWS Fargate containers, and AWS Lambda functions across multiple AWS Regions. The company wants to reduce costs by making a 1-year commitment for compute usage. The company needs a flexible purchasing option that automatically applies the discounted rate to any EC2 instance, Fargate, or Lambda usage, regardless of region, instance family, or size. Which AWS purchasing option should the company use?

Accepted Answer

Compute Savings Plan. A Compute Savings Plan is the correct choice because it offers the most flexibility, automatically applying discounted rates to any EC2 instance, Fargate, or Lambda usage across any AWS Region, instance family, or size. This matches the company's requirement for a 1-year commitment that covers diverse compute services without regional or instance constraints.

Question 11

A company operates 10 AWS accounts, each managed by a different department. The finance team wants to combine the usage of all accounts to qualify for lower volume-based pricing tiers for services such as Amazon S3 and Amazon EC2. Additionally, they want a single monthly bill that aggregates charges from all accounts. Which AWS feature should the company use to meet these requirements?

Accepted Answer

AWS Organizations with consolidated billing. AWS Organizations with consolidated billing is the correct feature because it allows the company to combine usage across all 10 AWS accounts into a single aggregated bill. This enables the finance team to qualify for lower volume-based pricing tiers for services like Amazon S3 and Amazon EC2, as AWS aggregates usage across all accounts in the organization. Consolidated billing also provides a single monthly bill that itemizes charges from each account, meeting both requirements.

Question 12

A company is migrating a business-critical workload to AWS. The company wants to ensure it has access to a dedicated Technical Account Manager (TAM) who will provide proactive guidance, architectural reviews, and operational support. Additionally, the company requires the Infrastructure Event Management (IEM) service to assist with the migration launch, and it wants the full set of AWS Trusted Advisor best practice checks across all categories (cost optimization, performance, security, fault tolerance, service limits). Which AWS Support plan should the company select?

Accepted Answer

AWS Enterprise Support. AWS Enterprise Support is the only plan that provides a dedicated Technical Account Manager (TAM) for proactive guidance, architectural reviews, and operational support. It also includes Infrastructure Event Management (IEM) for migration launches and full access to all AWS Trusted Advisor best practice checks across all categories, including cost optimization, performance, security, fault tolerance, and service limits. Lower-tier plans lack one or more of these critical features.

Question 13

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?

Accepted Answer

AWS Budgets with budget actions. 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.

Question 14

A company operates 10 AWS accounts under AWS Organizations. Each account runs multiple projects, and the company tags all resources with a 'Project' tag (e.g., 'Project-A', 'Project-B'). The finance team wants to view the consolidated monthly bill broken down by the value of the 'Project' tag across all accounts. Which AWS feature should the team use to achieve this?

Accepted Answer

Activate the 'Project' tag as a cost allocation tag in the AWS Organizations payer account's Billing and Cost Management console.. Option B is correct because cost allocation tags in the AWS Organizations payer account's Billing and Cost Management console allow you to activate user-defined tags (like 'Project') so that AWS can break down the consolidated monthly bill by those tag values across all linked accounts. Once activated, the cost data is available in Cost Explorer and the Cost & Usage Report, enabling the finance team to view spending per project without manual aggregation.

Answer

Create an AWS Budget for each 'Project' tag value and set cost alerts to track spending per project.

Answer

Use AWS Trusted Advisor to generate a cost optimization report that shows which projects are over-spending based on the 'Project' tag.

Answer

Configure AWS Compute Optimizer to analyze costs per project and recommend resource downsizing based on the 'Project' tag.

Question 15

A company runs a steady-state production workload on a fixed number of m5.large EC2 instances in the us-east-1 region. The workload runs 24/7 and the instance type and region are not expected to change. The company wants to obtain the highest possible discount for this workload with a 3-year commitment. Which purchasing option should the company choose?

Accepted Answer

Standard Reserved Instances (3-year, All Upfront). Standard Reserved Instances (3-year, All Upfront) offer the highest discount for a steady-state workload with a fixed instance type and region because they provide a significant discount over On-Demand pricing in exchange for a commitment to a specific instance family, size, and Availability Zone. Since the workload runs 24/7 on m5.large instances in us-east-1 and the configuration is not expected to change, Standard RIs maximize savings without the flexibility trade-offs that reduce discount rates.
