CLF-C02 Billing, Pricing, and Support Practice Test 5 — 15 Questions

Question 1

A company tags all Amazon EC2 instances with a 'Project' tag to track costs. The finance team reviews cost data in AWS Cost Explorer but cannot filter or group by the 'Project' tag. The tags are visible in the EC2 console. What is the most likely reason the tags are not appearing in Cost Explorer?

Accepted Answer

The tags have not been activated as cost allocation tags in the Billing and Cost Management console.. B is correct because cost allocation tags must be explicitly activated in the Billing and Cost Management console before they appear in AWS Cost Explorer. Even though the 'Project' tag is applied to EC2 instances and visible in the EC2 console, AWS does not automatically treat resource tags as cost allocation tags; activation is a separate, required step. Without activation, Cost Explorer cannot filter or group by that tag.

Answer

The tags are not applied to the root volumes of the EC2 instances.

Answer

Cost Explorer requires at least 30 days of tag usage data before tags become available.

Answer

The finance team does not have the iam:ListAccountAliases permission.

Question 2

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?

Accepted Answer

AWS Business Support. 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.

Question 3

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?

Accepted Answer

Compute Savings Plans. 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.

Question 4

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?

Accepted Answer

Consolidated Billing through AWS Organizations. 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.

Question 5

A company manages 15 AWS accounts through AWS Organizations. The finance team needs to perform custom analysis of monthly costs across all accounts. They want to download a detailed, hourly-level CSV file that breaks down usage and costs by service, by member account, and by user-defined cost allocation tags. The file must be delivered to an Amazon S3 bucket daily, and the team will then query the data using Amazon Athena and create dashboards in Amazon QuickSight. Which AWS feature should they configure to meet these requirements?

Accepted Answer

AWS Cost and Usage Report (CUR). The AWS Cost and Usage Report (CUR) is the only feature that delivers a detailed, hourly-level CSV file with granular breakdowns by service, member account, and user-defined cost allocation tags. It can be automatically published to an S3 bucket daily, enabling downstream analysis with Athena and QuickSight.

Question 6

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?

Accepted Answer

AWS Budgets. 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.

Question 9

A company operates over 100 AWS accounts consolidated under AWS Organizations. The finance team needs to analyze the company's historical AWS spending across all accounts for the past 6 months. They want to understand which services and regions drive the most costs, and they also need a 3-month forecast of future spending to inform budget planning. The team needs a visual dashboard that allows interactive filtering by account, service, and region without requiring custom scripts. Which AWS tool should the finance team use to meet these requirements?

Accepted Answer

AWS Cost Explorer. AWS Cost Explorer provides a pre-built, interactive dashboard that visualizes historical cost data (up to 12 months) and generates forecasts (up to 12 months) without requiring custom scripts. It supports filtering by account, service, and region, making it ideal for the finance team's requirements.

Question 11

A company runs hundreds of Amazon EC2 instances across multiple accounts. The finance team wants to identify over-provisioned instances that are using more memory or CPU than necessary, so that they can downsize them and reduce monthly costs. The team needs automated, ongoing recommendations based on the actual utilization metrics of the instances. Which AWS service should the team use to meet these requirements?

Accepted Answer

AWS Compute Optimizer. AWS Compute Optimizer is the correct service because it uses machine learning to analyze historical utilization metrics (CPU, memory, and network) of EC2 instances and generates automated, ongoing recommendations for right-sizing or downsizing over-provisioned instances. This directly meets the finance team's requirement for automated, continuous recommendations based on actual utilization to reduce monthly costs.

Question 12

A company has multiple AWS accounts consolidated under AWS Organizations. The finance team wants to set a hard monthly cost limit for a development account. If the forecasted costs for the month exceed that limit, the team wants AWS to automatically stop all non-critical Amazon EC2 instances in that account to prevent overspending. The team also needs to receive an email alert when the cost threshold is first crossed. Which AWS service or feature should the team use to define the budget and configure the automated action?

Accepted Answer

AWS Budgets with an Amazon EC2 action. AWS Budgets allows you to set a cost budget with a threshold and, when forecasted costs exceed that threshold, trigger an AWS Budgets action to stop specific Amazon EC2 instances. This meets the requirement for a hard monthly cost limit and automated instance stoppage, while also sending an email alert via Amazon SNS when the threshold is first crossed.

Question 13

A company recently signed up for AWS and is using the 12-month Free Tier offer. In the first month, they launched a single Amazon EC2 t2.micro instance and used it for exactly 750 hours. In the second month, they launched a second t2.micro instance and ran both instances simultaneously for 500 hours each (a total of 1,000 instance-hours for the month). Which statement accurately describes the charges for the second month under the Free Tier?

Accepted Answer

The first 750 hours of combined usage across both instances are free, and the remaining 250 hours are charged.. Option C is correct because the AWS Free Tier for EC2 provides 750 hours of t2.micro (or t3.micro) instance usage per month across all regions, aggregated across all instances. In the second month, the combined usage of both instances is 1,000 hours, so the first 750 hours are free, and the remaining 250 hours are charged at standard On-Demand rates. The Free Tier applies each month for the first 12 months, not just the first month, and the 750-hour limit is a pool shared by all eligible instances.

Answer

The entire 1,000 hours are free because each instance is eligible for 750 free hours per month.

Answer

The first 500 hours of each instance are free, and the remaining 500 hours are charged.

Answer

The entire 1,000 hours are charged because the Free Tier only applies to the first month.

Question 14

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?

Accepted Answer

Activate cost allocation tags, tag all resources with a department identifier, and use Cost Explorer to filter and group costs by the tag.. Option A is correct because 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.

Answer

Set up separate payment methods for each department's AWS account so that each department receives its own bill.

Answer

Create a dedicated AWS account for each department and manually sum the charges from each account's monthly bill.

Answer

Use AWS Budgets to set a spending threshold for each department and review the alerts to estimate departmental costs.

Question 15

A company's finance team needs to analyze AWS spending in detail. They require a report that includes hourly cost data for each AWS service, each individual resource (e.g., a specific EC2 instance), and any cost allocation tags applied. The team plans to export this data to an Amazon S3 bucket and then import it into a custom business intelligence (BI) analytics dashboard. Which AWS tool should the finance team use to generate this level of detailed cost data?

Accepted Answer

AWS Cost and Usage Report. The AWS Cost and Usage Report (CUR) is the correct tool because it provides the granular, hourly cost data broken down by AWS service, individual resource (e.g., specific EC2 instance IDs), and cost allocation tags. It can be delivered to an S3 bucket for integration with custom BI tools like Amazon QuickSight or third-party dashboards, meeting the finance team's exact requirements.
