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 C and D are correct. AWS CloudTrail can be configured to log API calls to S3, including data events for object-level access. Amazon S3 server access logs provide detailed records of requests made to an S3 bucket. Option A is wrong because AWS Config records configuration changes, not data access logs. Option B is wrong because Amazon CloudWatch Logs can store logs but does not generate S3 access logs directly. Option E is wrong because VPC Flow Logs capture IP traffic metadata, not S3 object-level access.
