This DOP-C02 practice question tests your understanding of monitoring and logging. 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 company uses AWS CloudTrail to log all API calls in their AWS account. They need to ensure that any changes to CloudTrail configuration (such as disabling the trail or modifying the log file validation) are immediately detected and trigger an automated response. Which solution should the DevOps engineer implement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an Amazon EventBridge rule that matches CloudTrail API calls like StopLogging or UpdateTrail and triggers an SNS topic.
Option D is correct because CloudTrail itself logs changes to its configuration, so a CloudWatch Events (now Amazon EventBridge) rule can be created to match API calls that modify CloudTrail (e.g., StopLogging, UpdateTrail) and trigger an SNS notification or Lambda for automated response. Option A is wrong because Config rules can detect configuration drift but are not real-time. Option B is wrong because GuardDuty focuses on security threats, not CloudTrail configuration changes. Option C is wrong because Trusted Advisor does not monitor CloudTrail changes.
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 Amazon GuardDuty and configure it to monitor CloudTrail logs for suspicious activity.
Why it's wrong here
GuardDuty is for threat detection, not configuration changes.
✓
Create an Amazon EventBridge rule that matches CloudTrail API calls like StopLogging or UpdateTrail and triggers an SNS topic.
Why this is correct
EventBridge can trigger in real-time on API calls.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use AWS Config rules with remediation actions to detect and revert changes to CloudTrail.
Why it's wrong here
AWS Config evaluates rules periodically, not in real-time.
✗
Use AWS Trusted Advisor to check CloudTrail configuration and send alerts via email.
Why it's wrong here
Trusted Advisor checks are not real-time and don't trigger automated responses.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
