This DOP-C02 practice question tests your understanding of monitoring and logging. 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 API activity across multiple accounts. The security team needs to ensure that all CloudTrail logs are delivered to a centralized S3 bucket in the audit account, and that any log file validation failures trigger an immediate notification. What should the engineer do to meet this requirement?
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 validation and create a CloudWatch alarm on the DigestDeliveryFailed metric
Option C is correct because enabling log file validation and creating a CloudWatch alarm on the DigestDeliveryFailed metric will trigger notifications. Option A is wrong because CloudTrail does not publish to SNS directly. Option B is wrong because CloudWatch Logs is for log streams, not CloudTrail. Option D is wrong because Lambda is not needed for this simple alert.
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 CloudTrail log file validation and create a CloudWatch alarm on the DigestDeliveryFailed metric
Read the scenario before looking for a memorised answer.
✗
Create a Lambda function that checks the integrity of logs and publishes to SNS
Why it's wrong here
This is overly complex; CloudTrail offers built-in validation.
✗
Configure CloudTrail to deliver logs to the S3 bucket and enable SNS notifications for all events
Why it's wrong here
CloudTrail cannot send notifications directly to SNS.
✗
Send CloudTrail logs to CloudWatch Logs and create a metric filter for validation errors
Why it's wrong here
CloudTrail logs can go to CloudWatch Logs, but log file validation is a separate feature.
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.
