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 CloudTrail
Options D and E are correct. AWS CloudTrail can log API calls to S3 by enabling data events, and S3 server access logs record detailed request information. Option A is wrong because IAM Access Analyzer reviews resource policies, not API calls. Option B is wrong because AWS Config tracks configuration changes, not API calls. Option C is wrong because VPC Flow Logs capture network traffic, not API calls.
