CLF-C02 Billing, Pricing, and Support Practice Test 10 — 15 Questions

Question 1

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?

Choose an answer to begin — your selection is scored in the full session.

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 2

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 3

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.

Answer

EC2 Instance Savings Plan

Answer

Standard Reserved Instance

Answer

Convertible Reserved Instance

Question 4

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 5

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 6

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 7

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.. 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 8

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?

Accepted Answer

Use S3 Standard for the first 30 days, then transition to S3 Glacier Flexible Retrieval.. 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.

Answer

Use S3 Standard for all data.

Answer

Use S3 Standard-IA for the first 30 days, then transition to S3 Glacier Deep Archive.

Answer

Use S3 One Zone-IA for the first 30 days, then transition to S3 Glacier Deep Archive.

Question 9

A company runs database servers that require consistent EC2 capacity 24/7 for the next 3 years. Which EC2 purchasing option provides the greatest discount compared to On-Demand pricing?

Accepted Answer

Reserved Instances (3-year, all upfront). Reserved Instances (RIs) with a 3-year term and all upfront payment provide the highest discount compared to On-Demand pricing because they commit to a consistent, predictable workload for an extended period. AWS offers significant pricing tiers for RIs, with the 3-year all upfront option yielding up to 72% discount over On-Demand, which is the greatest among all purchasing options for steady-state usage.

Answer

Spot Instances

Answer

On-Demand Instances

Answer

Dedicated Hosts

Question 10

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?

Accepted Answer

Spot Instances. 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.

Answer

On-Demand Instances

Answer

Reserved Instances

Answer

Dedicated Instances

Question 11

A solutions architect is designing a new architecture on AWS that includes EC2, RDS, S3, and data transfer. Before deploying anything, they want to estimate the monthly cost of running this architecture. Which AWS tool should they use?

Accepted Answer

AWS Pricing Calculator. AWS Pricing Calculator is the correct tool because it allows you to estimate the monthly cost of AWS services before deployment by specifying resource configurations (e.g., EC2 instance type, RDS storage, S3 data transfer). Unlike Cost Explorer, which analyzes historical costs, the Pricing Calculator provides upfront cost projections for new architectures.
