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
✓
Enable S3 Object Lock on the CloudTrail S3 bucket.
S3 Object Lock prevents objects from being deleted or overwritten, ensuring tamper-proof logs. Option B is correct because CloudTrail log file validation creates digest files that allow integrity verification. Option C is incorrect because server-side encryption with KMS protects data at rest but does not prevent tampering or deletion. Option D is incorrect because S3 Transfer Acceleration speeds up uploads but does not provide security. Option E is incorrect because lifecycle policies transition objects to cheaper storage classes but do not prevent modification or deletion.
