SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 troubleshooting an issue where CloudTrail is not delivering logs to an S3 bucket. The bucket policy appears correct. Which TWO additional steps should the engineer take to diagnose the issue? (Choose TWO.)
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
✓
Verify that the S3 bucket exists and is in the correct region.
Option A is correct because if the S3 bucket does not exist or is in a different region, CloudTrail cannot deliver log files to it. CloudTrail requires the bucket to be in the same region as the trail (for a single-region trail) or in the designated bucket region for a multi-region trail. Verifying the bucket's existence and region ensures the delivery path is valid. Option E is correct because the CloudTrail configuration in the AWS Management Console displays error messages related to delivery failures, such as bucket policy issues or permission errors. Reviewing this console can provide immediate insight into why logs are not being delivered, without needing to check other logs manually.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume CloudTrail uses an IAM role for S3 access (like many other AWS services), but CloudTrail relies solely on a resource-based bucket policy, so creating an IAM role (Option C) is unnecessary and incorrect.
Detailed technical explanation
How to think about this question
CloudTrail uses a service-linked principal (cloudtrail.amazonaws.com) to write logs to S3, and the bucket policy must grant s3:PutObject permission to that principal. If the bucket is in a different region, CloudTrail may fail with a 'BucketRegionMismatch' error, which is visible in the CloudTrail console's 'Error' column. Additionally, CloudTrail validates the bucket policy at trail creation and periodically, but misconfigurations like missing permissions or incorrect ARNs can cause silent failures.
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.
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
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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
