- A
Configure a CodeCommit trigger to start the pipeline on push events to the 'main' branch.
A push event to main (including pull request merges) triggers the pipeline automatically.
- B
Create a manual approval step before deployment and require a pull request merge as a trigger.
Why wrong: Manual approval is not automatic; does not trigger pipeline automatically.
- C
Use a scheduled trigger to run the pipeline every hour and check for changes.
Why wrong: Scheduled triggers are not event-driven and may cause unnecessary builds.
- D
Configure the source stage to use the 'main' branch and enable periodic polling.
Why wrong: Polling will detect any change on main, but also requires manual setup; but it will not differentiate pull request merges from direct pushes.
DVA-C02 Deployment Practice Question
This DVA-C02 practice question tests your understanding of deployment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 is using AWS CodePipeline with a multi-branch strategy. The pipeline includes a source stage from AWS CodeCommit, a build stage using AWS CodeBuild, and a deploy stage using AWS CodeDeploy. The team wants to automatically deploy changes only when a pull request is merged to the 'main' branch. Which configuration should be used?
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
Configure a CodeCommit trigger to start the pipeline on push events to the 'main' branch.
Option D is correct: CodePipeline should use a webhook trigger with an event filter for push events to the 'main' branch. Option A (all branches) would deploy every push. Option B (manual approval) defeats automation. Option C (scheduled) is not event-driven.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
