- A
Verify that the deployment group name specified in the pipeline's Deploy stage matches the actual deployment group name in CodeDeploy.
A typo or mismatch in the deployment group name causes this error.
- B
Confirm that the pipeline and the CodeDeploy deployment group are in the same AWS Region.
CodePipeline can only deploy to resources in the same region; cross-region deployment requires additional configuration.
- C
Increase the timeout for the Deploy stage to allow more time for the deployment group to be created.
Why wrong: Timeout does not affect existence of the deployment group.
- D
Ensure that the CodeBuild project has permissions to access the CodeDeploy deployment group.
Why wrong: CodeBuild does not interact directly with CodeDeploy; the pipeline service role does.
- E
Check that the CodeDeploy application exists in the same AWS account as the pipeline.
Why wrong: The pipeline and deployment group are likely in the same account; cross-account is possible but not typical for this error.
Quick Answer
The answer is to confirm that the pipeline and the CodeDeploy deployment group are in the same AWS Region and that the deployment group name specified in the pipeline’s Deploy stage matches exactly. This error occurs because CodePipeline resolves the deployment group as a resource within its own region; if the group exists in a different region or the name has a typo, the service cannot locate it, causing the "deployment group does not exist" failure. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of cross-service resource resolution and common misconfigurations in multi-stage pipelines. A frequent trap is assuming the error implies the group was deleted or lacks permissions, but the root cause is almost always a regional mismatch or a naming discrepancy. Remember the memory tip: "Region and name must be the same game" — always verify both the region selector and the exact deployment group name in the pipeline’s action configuration before troubleshooting further.
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 company uses AWS CodePipeline to automate deployments. The pipeline consists of Source, Build, and Deploy stages. The Build stage uses CodeBuild, and the Deploy stage uses CodeDeploy. Recently, the pipeline failed at the Deploy stage with an error: 'The deployment group does not exist'. Which TWO actions should the team take to resolve this issue?
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
Verify that the deployment group name specified in the pipeline's Deploy stage matches the actual deployment group name in CodeDeploy.
Options A and D are correct: the deployment group name must match exactly, and the pipeline must be in the same region. Option B is not required. Option C is not a common cause. Option E is not related.
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 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.
