- A
Update the IAM role for CodePipeline to allow it to list deployment groups.
Why wrong: The error message is not about permissions; it's about not finding the group.
- B
Confirm that the CodeDeploy deployment group exists in the same AWS Region as the pipeline.
Cross-region mismatches can cause this error.
- C
Check the CodeBuild build logs for errors.
Why wrong: The build succeeded, so logs are not the issue.
- D
Verify that the deploy stage in CodePipeline is configured with the correct deployment group name.
A typo or incorrect name would cause this error.
- E
Ensure the CodeCommit repository has a valid commit.
Why wrong: The source stage pulled code successfully.

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 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
✓
Confirm that the CodeDeploy deployment group exists in the same AWS Region as the pipeline.
Option B is correct because CodePipeline and CodeDeploy must operate in the same AWS Region. If the deployment group is in a different Region, CodePipeline cannot find it, resulting in the 'No deployments found' error. This is a common cross-Region misconfiguration that prevents the deploy stage from locating the specified deployment group.
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
The trap here is that candidates often assume the error is due to IAM permissions (Option A) or source issues (Option E), when the real cause is a Region mismatch or a misconfigured deployment group name in the pipeline definition.
Detailed technical explanation
How to think about this question
CodePipeline's deploy action uses the CodeDeploy API's GetDeploymentGroup call to validate the deployment group name and Region. If the deployment group name is misspelled or the Region differs, the API returns a 'DeploymentGroupDoesNotExistException', which surfaces as 'No deployments found'. Under the hood, CodePipeline passes the deployment group name as a parameter to the CodeDeploy client, which is Region-scoped; cross-Region calls require explicit ARN-based references, which are not supported for deployment groups in a basic pipeline setup.
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.
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.
