C

D

Explanation
Correct Answer: B - Create a report in Cost Explorer and download the report.
Why this is correct:
- Cost Explorer is specifically designed for cost analysis and reporting in AWS. It provides detailed cost and usage data that can be filtered, grouped, and analyzed.
- Cost Explorer allows you to create custom reports that can be organized by various dimensions, including:
- Service
- Linked account
- Usage type
- Tags (which can include user/department tags)
- Region
- API operation
- You can download these reports in CSV format for further analysis and budget planning.
- Cost Explorer provides granular cost data that can be broken down to show costs by user if proper tagging is implemented.
Why the other options are incorrect:
A. Run a query with Amazon Athena to generate the report.
- While Athena can query cost and usage data stored in S3, this requires setting up AWS Cost and Usage Reports (CUR) to S3 first, which is more complex.
- This approach is better for advanced analytics but not the "most efficient" way for a simple user-based cost report.
C. Access the bill details from the billing dashboard and download the bill.
- The billing dashboard provides high-level invoice information but lacks the granular, user-level detail required.
- Standard AWS bills don't break down costs by individual users unless specific tagging and account structures are in place.
D. Modify a cost budget in AWS Budgets to alert with Amazon Simple Email Service (Amazon SES).
- AWS Budgets is for setting cost thresholds and alerts, not for generating detailed cost reports by user.
- This solution would only send alerts when costs exceed thresholds, not provide the comprehensive report needed for budget planning.
Key Considerations:
- For accurate user-based reporting, ensure proper tagging of AWS resources with user/department tags.
- Enable AWS Cost Explorer in the AWS Management Console.
- Use Cost Explorer's filtering and grouping capabilities to create reports by tag values (e.g., "user" tag).
- Schedule regular report exports for ongoing budget planning.
This solution provides the most efficient, out-of-the-box approach to obtain user-level cost data for department budget planning.
