The correct approach is to use the AWS CloudTrail LookupEvents API to search for DeleteBucket events. CloudTrail records all management-plane API calls, including S3 bucket deletions, and the LookupEvents API allows you to filter by event name and resource name, making it straightforward to pinpoint who performed the action and when. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this question tests your understanding of CloudTrail’s role in incident response versus other logging services like S3 access logs or CloudWatch Logs. A common trap is confusing object-level access logs with bucket-level management events; remember that S3 access logs track GET/PUT operations, not DeleteBucket. Another pitfall is assuming the AWS Management Console itself tracks user actions—it does not; all console activity is captured by CloudTrail. Memory tip: think “DeleteBucket is a management event, so CloudTrail is your detective.”
DOP-C02 Incident and Event Response Practice Question
This DOP-C02 practice question tests your understanding of incident and event response. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A company uses AWS CloudTrail to log all API calls. During an incident investigation, a security engineer needs to identify who deleted an S3 bucket named 'critical-data' two days ago. Which approach will provide the necessary information?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS CloudTrail LookupEvents API to search for DeleteBucket events.
Option D is correct because CloudTrail logs all API calls, including DeleteBucket, and the LookupEvents API can be used to search for events. The engineer can filter by event name and resource name. Option A is wrong because S3 access logs record object-level access, not bucket deletion. Option B is wrong because CloudWatch Logs does not store CloudTrail events by default; they must be streamed. Option C is wrong because the AWS Management Console activity is also logged in CloudTrail; the console itself does not track user actions.
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.
✓
Use AWS CloudTrail LookupEvents API to search for DeleteBucket events.
Why this is correct
CloudTrail records DeleteBucket and LookupEvents can filter by event name and time.
Related concept
Read the scenario before looking for a memorised answer.
✗
Check the AWS Management Console activity history.
Why it's wrong here
The console does not have a built-in activity history for API calls.
✗
Review the S3 access logs for the bucket.
Why it's wrong here
S3 access logs record requests to objects, not bucket-level operations like deletion.
✗
Search CloudWatch Logs for 'DeleteBucket' events.
Why it's wrong here
CloudWatch Logs does not automatically contain CloudTrail events unless configured.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
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.
