The answer is a list of event IDs for PutBucketPolicy calls. This is correct because the CloudTrail lookup-events command with the filter for PutBucketPolicy retrieves historical API activity records, each identified by a unique event ID, rather than the policy document itself or any current state. On the AWS Certified Data Engineer Associate DEA-C01 exam, this tests your understanding that CloudTrail is an auditing service for past actions, not a tool for viewing live configurations or evaluating compliance. A common trap is assuming the output includes the full policy text, but lookup-events only returns metadata like event IDs, timestamps, and who initiated the call. Remember: CloudTrail tracks the trail, not the treasure—event IDs point to the action, not the policy content.
DEA-C01 Data Security and Governance Practice Question
This DEA-C01 practice question tests your understanding of data security and governance. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Network Topology
Refer to the exhibit. A data engineer runs this CLI command to investigate a recent change to an S3 bucket policy. What information does the command return?
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 it only returns the event IDs, not the full policy. 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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
The command does not evaluate compliance; it only retrieves events.
✗
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.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
