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
✓
The user cannot delete the bucket critical-data.
The policy explicitly denies the s3:DeleteBucket action on the critical-data bucket, overriding any allow.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The user can delete the bucket if allowed by another policy.
Why it's wrong here
An explicit deny overrides any allow.
- ✗
The user can still delete objects inside the bucket.
Why it's wrong here
The policy only restricts the DeleteBucket action, not object deletion.
- ✗
The user can delete any bucket except critical-data.
Why it's wrong here
The policy only denies delete on that one bucket; other buckets still allowed if other policies allow.
- ✓
The user cannot delete the bucket critical-data.
Why this is correct
The Deny effect prevents deletion of the specified bucket.
