- A
Enable S3 Versioning on the CloudTrail bucket.
Why wrong: Versioning preserves versions but does not validate integrity.
- B
Enable S3 server-side encryption with SSE-S3.
Why wrong: SSE-S3 only provides encryption, not integrity validation.
- C
Enable CloudTrail log file integrity validation.
This feature provides cryptographic verification of log file integrity.
- D
Enable S3 Object Lock on the CloudTrail bucket.
Why wrong: Object Lock prevents deletion but does not detect modification.

SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. 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 log all API calls in their AWS account. They need to ensure that log files are not tampered with after they are delivered to the S3 bucket. Which feature should be enabled to provide integrity validation?
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
✓
Enable CloudTrail log file integrity validation.
CloudTrail log file integrity validation uses a SHA-256 hash chain to detect if log files have been modified, deleted, or tampered with after delivery to S3. When enabled, CloudTrail delivers a digest file that contains hashes of the log files, allowing you to verify that no unauthorized changes have occurred. This is the only feature specifically designed for integrity validation of CloudTrail logs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable S3 Versioning on the CloudTrail bucket.
Why it's wrong here
Versioning preserves versions but does not validate integrity.
- ✗
Enable S3 server-side encryption with SSE-S3.
Why it's wrong here
SSE-S3 only provides encryption, not integrity validation.
- ✓
Enable CloudTrail log file integrity validation.
Why this is correct
This feature provides cryptographic verification of log file integrity.

- ✗
Enable S3 Object Lock on the CloudTrail bucket.
Why it's wrong here
Object Lock prevents deletion but does not detect modification.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse data protection features like encryption or versioning with integrity validation, but only CloudTrail's built-in integrity validation provides cryptographic proof that log files have not been tampered with after delivery.
Detailed technical explanation
How to think about this question
CloudTrail log file integrity validation creates a chain of digest files, each containing a SHA-256 hash of the previous digest and the current log files, enabling you to detect any break in the chain. The validation process uses the CloudTrail Digest API or the AWS CLI's `validate-logs` command, which automatically downloads and verifies the digest files against the public key stored in the CloudTrail bucket. This mechanism is based on RFC 6962-style Merkle tree concepts, ensuring that even a single bit change in a log file will cause the hash chain to fail.
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 |
