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
✓
S3 Server Access Logs
And E are correct: S3 Server-Side Encryption (SSE) encrypts data at rest, fulfilling the encryption requirement; S3 Server Access Logs log requests to the bucket, fulfilling the logging requirement. Option A (AWS Config) is incorrect because it monitors configuration changes, not data access. Option C (VPC Flow Logs) is incorrect because it captures network traffic, not S3 requests. Option D (AWS CloudTrail) is incorrect because CloudTrail logs API calls but S3 Server Access Logs provide more granular object-level logging, and the question asks for access logging, not API call logging.
