This DOP-C02 practice question tests your understanding of sdlc automation. 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 DevOps engineer is troubleshooting a failed AWS CloudFormation stack update. The stack contains an AWS::Lambda::Function resource. The update failed with the error 'Resource creation cancelled' after a timeout. The engineer wants to view the logs from the Lambda function during the stack update to diagnose the issue. What should the engineer do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Access the CloudWatch Logs log group for the Lambda function
CloudFormation does not directly capture Lambda function logs. The Lambda function logs are sent to Amazon CloudWatch Logs. The engineer should check the CloudWatch Logs log group for the specific function to see any errors during invocation. Option A is correct. Option B is wrong because the stack events do not include function logs. Option C is wrong because CloudFormation does not log function output. Option D is wrong because CodeBuild is not involved in this scenario.
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.
✗
Use AWS CodeBuild to build and test the function locally
Why it's wrong here
CodeBuild is not related to CloudFormation stack updates
✗
Enable detailed CloudFormation logging in the stack template
Why it's wrong here
CloudFormation does not have detailed logging for function output
✓
Access the CloudWatch Logs log group for the Lambda function
Why this is correct
Lambda writes logs to CloudWatch Logs automatically

Read the scenario before looking for a memorised answer.
✗
Review the CloudFormation stack events in the AWS Management Console
Why it's wrong here
Stack events show resource creation status, not function logs

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.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
