- A
Use AWS CloudTrail to review Canary API calls.
Why wrong: CloudTrail logs API calls to create canaries, not execution details.
- B
Increase the canary timeout configuration to allow more time for the endpoint to respond.
If the timeout is too low, increasing it may resolve false positives.
- C
Check the EC2 instance CPU utilization in the VPC where the canaries run.
Why wrong: Canaries run as Lambda functions, not on EC2 instances.
- D
Review VPC Flow Logs to see if requests are being dropped or denied.
Flow logs can reveal network issues causing timeouts.
- E
Examine the canary logs in CloudWatch Logs for error messages.
Canary logs contain output from the script execution.

DOP-C02 Monitoring and Logging Practice Question
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 Amazon CloudWatch Synthetics canaries to monitor its web application endpoints. The canaries are failing intermittently with timeout errors. The DevOps team needs to troubleshoot the root cause. Which THREE actions should they take? (Select THREE.)
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
✓
Increase the canary timeout configuration to allow more time for the endpoint to respond.
Options B, D, and E are correct. B: Increasing the canary timeout configuration can resolve timeout errors if the endpoint is slow but still functional. D: Reviewing VPC Flow Logs helps identify network issues such as dropped or denied requests that could cause timeouts. E: Examining canary logs in CloudWatch Logs provides detailed error messages and execution traces to pinpoint the failure cause. Option A is incorrect because CloudTrail records API calls, not canary execution details; canary logs are in CloudWatch Logs. Option C is incorrect because canaries run in AWS Lambda, not on EC2 instances, so EC2 CPU utilization is irrelevant.
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
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
