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 default encryption (SSE-S3).
Options B and C are correct. B: Enabling default encryption (SSE-S3) ensures data is encrypted at rest, protecting it from unauthorized access. C: Enabling S3 Block Public Access prevents any public access to the bucket and its objects, reducing the risk of data exposure. Option A is incorrect because server access logging provides audit trails, not a direct security improvement. Option D is incorrect because versioning helps with data recovery, not security. Option E is incorrect because lifecycle policies manage storage costs, not security.
