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.

✓
Enable bucket versioning.
Options A and D are correct. Enabling versioning helps protect against accidental deletion or overwrite, and bucket policies can restrict access to specific principals. Option B is wrong because public access is generally not recommended. Option C is wrong because lifecycle policies are for management, not security. Option E is wrong because encryption is important but does not enforce access control.
