The correct answer is that the CloudTrail trail is not configured to log data events. This is because S3 GetObject requests are classified as data events, not management events, and CloudTrail only captures object-level operations like GetObject when data event logging is explicitly enabled for the S3 bucket or all S3 buckets in the trail configuration. On the AWS Certified Data Engineer Associate DEA-C01 exam, this concept frequently appears in troubleshooting scenarios where a candidate sees management events but misses object-level reads, testing your understanding of the CloudTrail event types and their default settings. A common trap is assuming that any S3 API call is automatically logged, but CloudTrail’s default configuration only records management events such as CreateBucket or PutBucketPolicy. To remember this, think: “Data events need a data trail—if you want to see GetObject, you must enable data events.”
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 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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
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.
Option B is correct because 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.
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.
✗
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.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
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.

Common exam trap: answer the scenario, not the keyword

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.

Variation 1. A company must comply with a regulation that requires logging all access to sensitive data stored in Amazon S3. Which AWS services can be used to capture and store access logs? (Choose TWO.)
easy
A.AWS Config
B.Amazon CloudWatch Logs
✓ C.AWS CloudTrail
✓ D.Amazon S3 server access logs
E.VPC Flow Logs
Why C: Options B and D are correct. AWS CloudTrail logs API calls to S3. Amazon S3 server access logs provide detailed records of requests. Option A is wrong because Amazon CloudWatch Logs can receive logs but doesn't generate S3 access logs directly. Option C is wrong because AWS Config tracks configuration changes, not access. Option E is wrong because VPC Flow Logs capture network traffic, not S3 access.
