This DVA-C02 practice question tests your understanding of deployment. 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 development team uses AWS CodePipeline to automate deployments. The pipeline includes a build stage using AWS CodeBuild and a deploy stage using AWS CodeDeploy. After a recent change, the deploy stage fails intermittently with a timeout error. The CodeBuild stage succeeds. What should the team do to troubleshoot the issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the timeout value in the CodeDeploy deployment configuration.
Option D is correct because the intermittent timeout error in the deploy stage, despite a successful build, indicates that the CodeDeploy agent is taking longer than the configured timeout to complete the deployment lifecycle events (e.g., BeforeInstall, AfterInstall, ApplicationStart). Increasing the timeout value in the CodeDeploy deployment configuration gives the agent more time to finish these operations, which directly addresses the timeout failure without altering the build or permissions.
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.
✗
Ensure the deployment group is configured to use the correct Auto Scaling group.
Why it's wrong here
Configuration is likely correct.
✗
Verify that the CodeDeploy service role has sufficient permissions.
Why it's wrong here
Intermittent failures suggest timeout, not permissions.
✗
Check the buildspec.yml file for syntax errors.
Why it's wrong here
Build stage succeeds.
✓
Increase the timeout value in the CodeDeploy deployment configuration.
Why this is correct
Increasing timeout can resolve intermittent timeout errors.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse build-stage failures (CodeBuild) with deploy-stage failures (CodeDeploy), leading them to check buildspec.yml or permissions, when the intermittent timeout is a classic symptom of a deployment configuration timeout being too short for the application's startup or script execution time.
Detailed technical explanation
How to think about this question
CodeDeploy deployments have a default timeout of 30 minutes for each lifecycle event (e.g., ApplicationStop, BeforeInstall, AfterInstall, ApplicationStart, ValidateService). If a custom script (e.g., a shell command in appspec.yml) hangs or takes longer than expected due to resource contention or network latency, the deployment times out. Increasing the timeout in the deployment configuration (e.g., to 60 minutes) provides a buffer, but the team should also inspect the CodeDeploy agent logs at /opt/codedeploy-agent/deployment-root/deployment-logs/codedeploy-agent-deployments.log to identify the specific lifecycle event causing the delay.

TExam Day Tips
→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.
