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
✓
Versioning is enabled on the bucket.
'Status: Enabled' indicates that versioning is enabled on the bucket. Option B is incorrect because when versioning is enabled, all versions of objects are retained, not just the latest, unless lifecycle rules are configured to remove older versions. Option C is incorrect because the status is 'Enabled', not 'Suspended'. Option D is incorrect because 'MFA Delete' is a separate setting; the output shows 'MFADelete: Disabled', meaning MFA Delete is not enabled.
