DEA-C01 Data Security and Governance Practice Question
Network Topology
Refer to the exhibit. A data engineer runs the AWS CLI command to look up GetObject events. The output shows an event from the DataEngineer role. However, the engineer suspects that some GetObject requests are not being logged. What is the MOST likely reason?
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 CloudTrail trail is not configured to log data events.
CloudTrail must have Data Events enabled for S3 object-level operations such as GetObject. Option A is wrong because the event is logged, so the trail exists. Option C is wrong because the engineer is looking up events, not configuring logging. Option D is wrong because the lookup is for a specific region, but the bucket might be in a different region, but that would not cause missing logs if events are logged in the bucket's region.
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 IAM role does not have permission to read the CloudTrail logs.
Why it's wrong here
The engineer is using lookup-events, which does not require reading the log files directly.
- ✓
The CloudTrail trail is not configured to log data events.
Why this is correct
By default, CloudTrail does not log data events for S3 objects; they must be enabled.
- ✗
The trail is not enabled in the us-east-1 region.
Why it's wrong here
The command specifies us-east-1, and the event is found, so the trail is enabled there.
- ✗
The S3 bucket is in a different region than the CloudTrail trail.
Why it's wrong here
CloudTrail logs events for the region it is enabled in; if the bucket is in another region, events would be logged in that region's trail.
