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
✓
Use a bucket policy that denies PutObject without the x-amz-server-side-encryption header.
Options A and B are correct. A bucket policy that denies PutObject without the x-amz-server-side-encryption header enforces encryption at upload time, ensuring all objects are encrypted. Default encryption on the bucket automatically encrypts objects that are uploaded without encryption headers, covering cases where the policy may not apply. Option C (Cross-Region Replication) replicates objects but does not enforce encryption. Option D (Versioning) provides object version management and can help protect against overwrites, but does not enforce encryption. Option E (Server Access Logs) provides logging but does not enforce encryption.
