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
✓
A list of event IDs for PutBucketPolicy calls
The command uses CloudTrail's lookup-events to find all PutBucketPolicy API calls in a 24-hour period. It returns a list of events, each containing details like who made the call, when, and the request parameters. Option A is wrong because the command returns a list of event IDs, not an evaluation of compliance. Option B is wrong because the command does not show the current policy, only past events. Option C is wrong because the command does not evaluate compliance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
An evaluation of bucket policy compliance
Why it's wrong here
This command returns a list of events, not an evaluation of compliance. It provides event IDs and details of PutBucketPolicy calls, but does not assess whether the policy complies with any rules.
- ✗
The current bucket policy for all buckets
Why it's wrong here
The command does not show current policies; it shows historical API calls.
- ✗
A report of all S3 bucket policy changes
Why it's wrong here
It only shows PutBucketPolicy events, not other policy changes.
- ✓
A list of event IDs for PutBucketPolicy calls
Why this is correct
The output includes event IDs, but also other details like user identity and timestamp.
