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
✓
Default encryption
S3 bucket default encryption ensures that all objects uploaded to the bucket are encrypted at rest. Option A (Versioning) is for preserving object versions, not encryption. Option B (MFA Delete) adds multi-factor authentication for delete operations, not encryption. Option C (Server access logging) logs access requests, not encryption. Therefore, enabling Default encryption is the correct property to enforce encryption at rest.
