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 monitor API activity. The security team notices that an IAM user 'dev-user' deleted an S3 bucket. They need to quickly identify the source IP address of the delete request. Which CloudTrail feature should they use to find this information?
Use CloudTrail Lake to query the event and extract the IP address from the userIdentity field.
Why wrong: The userIdentity field does not contain the IP address; the sourceIPAddress field does.
B
Check S3 server access logs for the bucket deletion event.
Why wrong: S3 server access logs record requests to the bucket, but the bucket deletion itself is an API call tracked by CloudTrail, not S3 access logs.
C
Enable CloudTrail Insights to analyze unusual activity.
Why wrong: CloudTrail Insights detects anomalies but does not directly show the source IP for a specific event.
D
Search the CloudTrail event history for the delete event and review the sourceIPAddress field.
CloudTrail event history includes the sourceIPAddress field in the event record.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Search the CloudTrail event history for the delete event and review the sourceIPAddress field.
Option B is correct because CloudTrail event history includes the sourceIPAddress field in the event record, which directly provides the IP address from which the API call was made. Option A is wrong because CloudTrail Insights detects unusual activity but does not provide the IP address for individual events. Option C is wrong because CloudTrail Lake is used for aggregating and querying trails but the source IP is still found in the event record. Option D is wrong because S3 server access logs are separate from CloudTrail and do not capture IAM user activity.
Key principle: 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.
