CLF-C02 Billing, Pricing, and Support Practice Question
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?
⚠ Common exam trap
Many candidates confuse AWS Cost Explorer's manual CSV export capability with the automated, granular, S3-delivered reporting that only CUR provides, especially when the question emphasizes hourly detail and daily delivery to S3.
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 (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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Budgets
Why it's wrong here
AWS Budgets allows you to set spending limits and receive alerts when costs exceed thresholds, but it does not generate a detailed hourly CSV file that can be delivered to Amazon S3 for custom analysis. It is not designed for exporting raw billing data.
When this WOULD be correct
A company wants to set a monthly cost budget for a specific AWS service and receive an email alert when actual costs exceed 80% of the budget. AWS Budgets would be the correct feature to configure for this alerting requirement.
- ✗
AWS Cost Explorer
Why it's wrong here
AWS Cost Explorer provides visualizations and can export CSV data, but it only offers aggregated data at a daily or monthly level, not hourly granularity. Additionally, it does not automatically deliver the file to an S3 bucket for downstream processing with Athena.
When this WOULD be correct
A company needs to view and analyze historical cost data and usage patterns through a web interface, with the ability to filter by service, linked account, or tags, but does not require raw data export to S3 or Athena integration.
- ✓
AWS Cost and Usage Report (CUR)
Why this is correct
The AWS Cost and Usage Report contains the most detailed billing data available, including hourly usage and costs, broken down by service, member account, and cost allocation tags. It can be delivered to an S3 bucket on a daily basis, making it ideal for custom analysis with Amazon Athena and Amazon QuickSight.
- ✗
AWS Trusted Advisor
Why it's wrong here
AWS Trusted Advisor offers recommendations to optimize costs, improve performance, and enhance security, but it does not provide a raw billing data export. It cannot generate CSV files with hourly usage and cost data for custom analysis.
When this WOULD be correct
A company wants to identify underutilized Amazon EC2 instances across multiple accounts to reduce costs. AWS Trusted Advisor would be the correct feature to use because it provides cost optimization checks that highlight idle or low-utilization resources, enabling the team to take action.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓AWS Cost and Usage Report (CUR)Correct answer▾
Why this is correct
The AWS Cost and Usage Report contains the most detailed billing data available, including hourly usage and costs, broken down by service, member account, and cost allocation tags. It can be delivered to an S3 bucket on a daily basis, making it ideal for custom analysis with Amazon Athena and Amazon QuickSight.
✗AWS BudgetsWrong answer — click to see why▾
Why this is wrong here
AWS Budgets provides cost alerts and notifications, but it does not generate detailed hourly-level CSV files with cost allocation tags or deliver them to S3 for Athena and QuickSight analysis.
★ When this WOULD be the correct answer
A company wants to set a monthly cost budget for a specific AWS service and receive an email alert when actual costs exceed 80% of the budget. AWS Budgets would be the correct feature to configure for this alerting requirement.
Why candidates choose this
Candidates may confuse AWS Budgets with cost reporting tools because both involve cost management, but Budgets focuses on thresholds and alerts, not detailed data export.
✗AWS Cost ExplorerWrong answer — click to see why▾
Why this is wrong here
AWS Cost Explorer provides visualizations and reports for cost analysis but does not generate hourly-level CSV files with detailed breakdowns by service, account, and tags, nor does it deliver files to S3 daily.
★ When this WOULD be the correct answer
A company needs to view and analyze historical cost data and usage patterns through a web interface, with the ability to filter by service, linked account, or tags, but does not require raw data export to S3 or Athena integration.
Why candidates choose this
Candidates may confuse Cost Explorer's cost analysis capabilities with the detailed, exportable data provided by CUR, or assume Cost Explorer can generate the required CSV files.
✗AWS Trusted AdvisorWrong answer — click to see why▾
Why this is wrong here
AWS Trusted Advisor provides best-practice recommendations for cost optimization, performance, security, and fault tolerance, but it does not generate detailed hourly CSV files with cost and usage data broken down by service, account, and tags, nor does it deliver such files to S3 for Athena and QuickSight analysis.
★ When this WOULD be the correct answer
A company wants to identify underutilized Amazon EC2 instances across multiple accounts to reduce costs. AWS Trusted Advisor would be the correct feature to use because it provides cost optimization checks that highlight idle or low-utilization resources, enabling the team to take action.
Why candidates choose this
Candidates may confuse Trusted Advisor's cost optimization recommendations with the ability to generate detailed cost and usage reports, or they may think it can export data to S3 for further analysis.

Same concept, more angles
2 more ways this is tested on CLF-C02
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company uses AWS Organizations with multiple accounts. The finance team needs to generate custom cost and usage reports that include every line item, all user-defined cost allocation tags, and resource-level details. The team also needs the ability to query the data using standard SQL tools for in-depth analysis. Which AWS feature should the team use to meet these requirements?
medium- A.AWS Budgets
- B.AWS Cost Explorer
- ✓ C.AWS Cost and Usage Report
- D.AWS Trusted Advisor
Why C: The AWS Cost and Usage Report (CUR) is the only AWS feature that provides comprehensive, granular cost and usage data including every line item, all user-defined cost allocation tags, and resource-level details. It delivers this data to an Amazon S3 bucket in a CSV or Parquet format, which can then be queried using standard SQL tools via Amazon Athena or other SQL engines. This directly matches the requirement for custom reports and SQL-based analysis.
Variation 2. 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?
medium- A.AWS Cost Explorer
- B.AWS Budgets
- ✓ C.AWS Cost and Usage Report
- D.AWS Trusted Advisor
Why C: 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.
