Question 1,734 of 1,740

SDLC Automation →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the pipeline is configured as a single-region pipeline, but the Deploy action is in a different region. This error occurs because CodePipeline, by default, operates entirely within a single region; when a Deploy stage references a deployment group in a different region—such as a CodeDeploy application in us-west-2 while the pipeline itself is defined in us-east-1—the service cannot locate that group unless cross-region actions are explicitly enabled with a separate artifact bucket in the target region. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of CodePipeline’s regional boundaries and the requirement to configure cross-region actions for multi-region deployments. A common trap is assuming that simply specifying a different region’s resource ARN will work, but the pipeline’s default scope is locked to its home region. Remember the tip: “One pipeline, one region—unless you configure cross-region action storage.”

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 reviewing the CodePipeline structure above. The pipeline fails during the Deploy stage with an error: 'The deployment group could not be found.' What is the most likely cause?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

}

A
The pipeline is configured as a single-region pipeline, but the Deploy action is in a different region.
Cross-region actions require explicit configuration; the pipeline is in us-east-1 and cannot deploy to us-west-2 without cross-region setup.
B
The source artifact is not accessible from us-west-2.
Why wrong: Artifact accessibility is not the error; the error is about deployment group not found.
C
The CodeDeploy application does not exist in us-west-2.
Why wrong: The error indicates deployment group not found, but the region mismatch is the root cause.
D
The CodeBuild project is not configured to output artifacts.
Why wrong: Missing artifacts would cause a different error.

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

✓

The pipeline is configured as a single-region pipeline, but the Deploy action is in a different region.

The pipeline stages are in different regions: Build in us-east-1, Deploy in us-west-2. CodePipeline does not support cross-region actions unless cross-region action is configured with proper artifact storage. The default pipeline runs in a single region. Option B is correct.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
