CLF-C02 Billing, Pricing, and Support Practice Question
A company uses AWS Organizations to manage multiple accounts. The finance team needs to perform a detailed cost analysis by joining AWS usage data with their internal accounting system. They require hourly-level billing data that includes resource IDs, operation types, and cost allocation tags. The data must be available in a CSV file that can be imported into their financial software. Which AWS tool or service should the finance team use to meet this requirement?
⚠ Common exam trap
Many candidates confuse AWS Cost Explorer's ability to filter by resource IDs and tags with the ability to export raw hourly-level data, but Cost Explorer only provides aggregated views and cannot deliver the granular CSV file required for external system import.
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
The AWS Cost and Usage Report (CUR) is the correct choice because it provides the most granular billing data available, including hourly-level usage, resource IDs, operation types, and cost allocation tags. The report can be delivered to an Amazon S3 bucket in CSV format, making it directly importable into the finance team's financial software for detailed cost analysis.
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 Cost Explorer
Why it's wrong here
Cost Explorer provides interactive charts and graphs for visualizing cost and usage data, and it offers forecasting, but it does not export hourly-level raw data with resource IDs and tags in CSV format as required.
When this WOULD be correct
A finance team needs to visualize and analyze AWS cost and usage trends over time, identify cost drivers, and create custom reports without needing raw hourly data or integration with an external accounting system.
- ✗
AWS Budgets
Why it's wrong here
AWS Budgets enables you to set custom spending or usage limits and receive alerts via CloudWatch alarms when actual or forecasted costs exceed thresholds. However, it only provides aggregated, summarized views of cost data for monitoring purposes, not the granular hourly usage data with resource IDs and tags required for integration with an external accounting system. Furthermore, budgets cannot export raw billing data to your own S3 bucket for custom analysis.
When this WOULD be correct
A company needs to set cost thresholds and receive notifications when spending exceeds or is forecasted to exceed a defined budget, without requiring granular hourly usage data or integration with an internal accounting system.
- ✓
AWS Cost and Usage Report
Why this is correct
AWS Cost and Usage Report (CUR) delivers the most comprehensive billing data, including hourly usage, resource IDs, operation types, and tags. It can be configured to deliver CSV files to an S3 bucket, enabling integration with external financial systems.
- ✗
AWS Trusted Advisor
Why it's wrong here
AWS Trusted Advisor performs automated checks across cost optimization, security, fault tolerance, and performance, providing recommended actions based on AWS best practices. It inspects your account configuration and resources, but it does not generate nor export the underlying raw billing and usage records needed for custom financial analysis. Since this company requires detailed cost and usage data files delivered to S3, Trusted Advisor's advisory output is insufficient for that purpose.
When this WOULD be correct
A company wants to identify underutilized Amazon EC2 instances to reduce costs. AWS Trusted Advisor would be the correct service to use because it checks for idle instances and provides cost optimization recommendations.
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 ReportCorrect answer▾
Why this is correct
AWS Cost and Usage Report (CUR) delivers the most comprehensive billing data, including hourly usage, resource IDs, operation types, and tags. It can be configured to deliver CSV files to an S3 bucket, enabling integration with external financial systems.
✗AWS Cost ExplorerWrong answer — click to see why▾
Why this is wrong here
AWS Cost Explorer provides visualizations and filtering of cost data but does not support exporting hourly-level billing data with resource IDs, operation types, and cost allocation tags in CSV format for integration with external accounting systems.
★ When this WOULD be the correct answer
A finance team needs to visualize and analyze AWS cost and usage trends over time, identify cost drivers, and create custom reports without needing raw hourly data or integration with an external accounting system.
Why candidates choose this
Candidates may think Cost Explorer can export detailed billing data because it offers CSV downloads, but those exports are aggregated and lack the granularity (hourly, resource-level) required for detailed cost analysis.
✗AWS BudgetsWrong answer — click to see why▾
Why this is wrong here
AWS Budgets provides cost alerts and tracking against budgets, but it does not generate hourly-level billing data with resource IDs, operation types, and cost allocation tags in a CSV file for detailed cost analysis.
★ When this WOULD be the correct answer
A company needs to set cost thresholds and receive notifications when spending exceeds or is forecasted to exceed a defined budget, without requiring granular hourly usage data or integration with an internal accounting system.
Why candidates choose this
Candidates may confuse AWS Budgets with a tool that provides detailed cost data because it tracks costs and can send alerts, but it lacks the granularity and export format required for this specific use case.
✗AWS Trusted AdvisorWrong answer — click to see why▾
Why this is wrong here
AWS Trusted Advisor provides recommendations for cost optimization, security, and performance, but it does not generate hourly-level billing data with resource IDs, operation types, and cost allocation tags in a CSV format for detailed cost analysis.
★ When this WOULD be the correct answer
A company wants to identify underutilized Amazon EC2 instances to reduce costs. AWS Trusted Advisor would be the correct service to use because it checks for idle instances and provides cost optimization recommendations.
Why candidates choose this
Candidates may mistakenly think Trusted Advisor can export detailed billing data because it offers cost optimization checks, but it only provides high-level recommendations, not raw usage data.

Variation 1. A company uses AWS Organizations with separate accounts for development, testing, and production. The finance team wants to track monthly spending by internal project, but a single project may use resources across multiple accounts. The team has applied a 'Project' tag to all resources. They need a detailed billing report that shows costs grouped by this Project tag, combining data from all accounts. Which AWS feature should they enable to meet this requirement?
medium- A.AWS Consolidated Billing
- B.AWS Cost Explorer with tag filtering
- C.AWS Budgets with tag-based alerts
- ✓ D.AWS Cost and Usage Reports with cost allocation tags activated
Why D: AWS Cost and Usage Reports (CUR) with cost allocation tags activated is the correct choice because it provides the most detailed billing data, including all tags, and can be delivered to an S3 bucket for analysis. This allows the finance team to group costs by the 'Project' tag across all accounts in the AWS Organization, meeting the requirement for a detailed, combined report.
