- A
AWS Cost Explorer
Why wrong: Cost Explorer provides a graphical interface to explore historical cost and usage data and offers forecasting, but it does not export raw hourly-level data to an S3 bucket for custom reporting.
- B
AWS Budgets
Why wrong: AWS Budgets allows you to set cost and usage budgets and receive alerts, but it does not generate detailed exportable reports with granular hourly resource-level data.
- C
AWS Cost and Usage Report
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.
- D
AWS Trusted Advisor
Why wrong: AWS Trusted Advisor inspects your environment and provides recommendations for cost optimization, security, performance, and fault tolerance, but it does not generate exports of granular cost and usage data.
CLF-C02 Billing, Pricing, and Support Practice Question
This CLF-C02 practice question tests your understanding of billing, pricing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
The AWS Cost and Usage Report (CUR) is delivered as a CSV or Parquet file in an S3 bucket, containing line items for each resource usage record with fields like instance type, operating system, and custom tags. It supports hourly granularity and can be integrated with tools like Amazon Athena or AWS Glue for querying, or transferred on-premises via AWS DataSync or S3-to-on-premises scripts. A key subtlety is that CUR data is typically updated at least once per day, so for near-real-time needs, additional services like AWS Cost Explorer API may be considered, but CUR remains the most granular export option.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
