The correct answer is to specify the S3 bucket ARN or prefix in the trail configuration, alongside explicitly selecting Data events in the CloudTrail trail settings. This is because CloudTrail data events capture object-level operations such as GetObject, PutObject, and DeleteObject, whereas management events only cover bucket-level actions like CreateBucket. On the AWS Certified Security Specialty SCS-C02 exam, this distinction is frequently tested to ensure you understand that enabling CloudTrail data events for S3 object-level logging requires both a targeted resource scope (the bucket ARN or prefix) and the correct event type selection. A common trap is assuming that simply enabling CloudTrail will log all S3 activity; in reality, data events must be explicitly configured and are not enabled by default. Remember the mnemonic: “Data needs details, management is macro”—data events require granular resource specification, while management events handle broad bucket operations.
SCS-C02 Threat Detection and Incident Response Practice Question
This SCS-C02 practice question tests your understanding of threat detection and incident response. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 security engineer is configuring AWS CloudTrail to monitor data events for S3 objects. Which TWO of the following must be enabled to log object-level operations? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable data events in the CloudTrail trail.
Option A is correct because CloudTrail data events capture S3 object-level operations such as GetObject, PutObject, and DeleteObject. To enable this, you must explicitly select 'Data events' in the CloudTrail trail configuration, as management events only cover bucket-level operations like CreateBucket.
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.
✓
Enable data events in the CloudTrail trail.
Why this is correct
Data events capture object-level operations.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable S3 server access logs on the bucket.
Why it's wrong here
S3 server access logs are separate and not required for CloudTrail data events.
✗
Enable management events in the CloudTrail trail.
Why it's wrong here
Management events log control plane operations, not object-level operations.
✗
Enable S3 Object Lambda.
Why it's wrong here
S3 Object Lambda is not related to logging.
✓
Specify the S3 bucket ARN or prefix in the trail configuration.
Why this is correct
You must specify which S3 resources to log.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse management events (which log bucket-level actions) with data events (which log object-level actions), leading them to select Option C instead of recognizing that both data events and a specific bucket ARN or prefix are required.
Detailed technical explanation
How to think about this question
CloudTrail data events for S3 are logged at the object level by specifying the bucket ARN or a prefix (e.g., arn:aws:s3:::example-bucket/prefix/*). This enables granular auditing of read and write actions, which is critical for compliance frameworks like PCI DSS or SOC 2. Note that data events can generate high volumes of logs, so you should use selective logging (e.g., only specific prefixes) to manage costs and noise.

TExam Day Tips
→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

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.
