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
✓
It allows s3:PutBucketPolicy only if the bucket ACL is set to bucket-owner-full-control.
The SCP denies s3:PutBucketPolicy only when the bucket ACL is not set to 'bucket-owner-full-control'. If the ACL is set to that value, the action is allowed. Thus, it ensures that when a bucket policy is created, the ACL must grant full control to the bucket owner. It does not deny all PutBucketPolicy actions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It allows s3:PutBucketPolicy only if the bucket ACL is set to bucket-owner-full-control.
Why this is correct
The Deny is conditional; if the condition is not met (i.e., ACL is correct), the action is allowed.
- ✗
It denies all s3:PutBucketPolicy actions on all buckets.
Why it's wrong here
The condition only denies if the ACL is not bucket-owner-full-control.
- ✗
It denies s3:PutBucketPolicy for any bucket that does not have an ACL.
Why it's wrong here
The condition checks the ACL value, not its absence.
- ✗
It allows s3:PutBucketPolicy for buckets owned by the management account.
Why it's wrong here
The policy does not reference ownership.
