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 with data events enabled
AWS CloudTrail can log S3 API calls such as GetObject, PutObject, and ListObjects when data events are enabled, capturing details like who accessed an object and from which IP address. Option D is incorrect because S3 Server Access Logs provide object-level logs but do not include IAM user or role details. Option B is incorrect because Amazon CloudWatch Logs can store and monitor logs but does not capture S3 data events directly. Option C is incorrect because AWS Config records resource configuration changes, not data access events.
