The correct answer is to verify that the deploy stage in CodePipeline is configured with the correct deployment group name and to confirm that the specified deployment group still exists in CodeDeploy. This error occurs because the CodePipeline deploy stage sends a request to CodeDeploy using a deployment group name, and if that name is misspelled, belongs to a different application, or has been deleted, CodeDeploy cannot find a matching target, causing the stage to fail. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of cross-service configuration dependencies, specifically how CodePipeline references CodeDeploy resources by name and region. A common trap is assuming the issue is with IAM permissions or the build artifact, but the error message explicitly points to a missing deployment group, not an authorization failure. Remember the mnemonic: "Name and Existence" — always check the deployment group name spelling first, then verify it hasn't been removed or recreated under a different application.
DOP-C02 SDLC Automation Practice Question
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 CodePipeline execution. The pipeline has a source stage from CodeCommit, a build stage using CodeBuild, and a deploy stage using CodeDeploy. The build stage succeeds, but the deploy stage fails with 'No deployments found for the specified deployment group.' Which TWO actions should the engineer take to resolve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Confirm that the CodeDeploy deployment group exists in the same AWS Region as the pipeline.
Options A and D are correct. The error suggests the pipeline cannot find the deployment group, often due to incorrect configuration or region mismatch. Checking the deploy stage configuration ensures the deployment group name is correct. Verifying the deployment group exists confirms it's not deleted. Option B is unnecessary if the build succeeded. Option C is unrelated. Option E is about IAM, but the error message is about missing deployment group.
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.
✗
Update the IAM role for CodePipeline to allow it to list deployment groups.
Why it's wrong here
The error message is not about permissions; it's about not finding the group.
✓
Confirm that the CodeDeploy deployment group exists in the same AWS Region as the pipeline.
Why this is correct
Cross-region mismatches can cause this error.
Related concept
Read the scenario before looking for a memorised answer.
✗
Check the CodeBuild build logs for errors.
Why it's wrong here
The build succeeded, so logs are not the issue.
✓
Verify that the deploy stage in CodePipeline is configured with the correct deployment group name.
Why this is correct
A typo or incorrect name would cause this error.
Related concept
Read the scenario before looking for a memorised answer.
✗
Ensure the CodeCommit repository has a valid commit.
Why it's wrong here
The source stage pulled code successfully.
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.

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.
