This DOP-C02 practice question tests your understanding of monitoring and logging. 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 company is using AWS CloudTrail to log API activity across multiple accounts. The security team wants to ensure that all CloudTrail logs are delivered to a central Amazon S3 bucket and that the logs are encrypted and cannot be deleted. Which THREE steps should the team take to meet these requirements? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable default encryption (SSE-S3) on the central S3 bucket.
Options A, C, and D are correct. Enabling log file validation (A) ensures integrity. Enabling SSE-S3 encryption (C) encrypts logs at rest. Enabling S3 Object Lock (D) prevents deletion. Option B (enable log file integrity) is duplicate of A? Actually, CloudTrail log file validation provides integrity. Option E (enable MFA Delete) is not supported on S3 buckets for this purpose; Object Lock is used.
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 MFA Delete on the central S3 bucket to require multi-factor authentication for deletions.
Why it's wrong here
MFA Delete is not a supported feature for CloudTrail log delivery; Object Lock is used.
✓
Enable default encryption (SSE-S3) on the central S3 bucket.
Read the scenario before looking for a memorised answer.
✓
Enable S3 Object Lock on the central S3 bucket to prevent log file deletion.
Why this is correct
Object Lock prevents objects from being deleted for a specified retention period.

✗
Enable CloudTrail log file integrity by using AWS KMS.
Why it's wrong here
Log file validation is the feature for integrity; KMS is for encryption.
✓
Enable CloudTrail log file validation to ensure log integrity.
Why this is correct
Log file validation allows you to verify that log files have not been modified.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
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.
