- A
AWS Cost Explorer
Why wrong: AWS Cost Explorer provides charts and CSV exports for exploring costs, but it does not automatically publish the most granular line-item data to an S3 bucket on a recurring schedule for custom BI integration.
- B
AWS Budgets
Why wrong: AWS Budgets allows you to set cost and usage budgets and receive alerts when thresholds are exceeded, but it does not export detailed cost and usage data to S3 for analysis.
- C
AWS Cost and Usage Reports
AWS Cost and Usage Reports (CUR) publishes the most granular cost and usage data, including resource-level details, to an S3 bucket in CSV format on a daily basis. This data can be ingested by third-party BI tools for custom analysis.
- D
AWS Trusted Advisor
Why wrong: AWS Trusted Advisor inspects your AWS environment and makes recommendations for cost optimization, security, and performance, but it does not export cost and usage data for analysis.
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 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?
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 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.
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 manual CSV export capability with the fully automated, scheduled export feature of AWS Cost and Usage Reports, leading them to incorrectly select Cost Explorer.
Detailed technical explanation
How to think about this question
AWS Cost and Usage Reports (CUR) can be configured to include hourly or daily granularity, resource IDs, and tags, and it delivers one or more CSV files per day to a specified S3 bucket using a manifest file for tracking. The data is normalized across all AWS services, making it ideal for custom queries via Amazon Athena or direct ingestion into BI tools like Tableau or Power BI. A subtle behavior is that CUR data can be delayed up to 24 hours, and the first report may take up to 48 hours to appear in the bucket.
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.
