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 team uses AWS CodeCommit for source control and wants to automatically trigger a build and deployment when code is pushed to the master branch. Which AWS service should be used to create this automation?
AWS CodeBuild
Why wrong: CodeBuild needs a trigger.
AWS CodePipeline
CodePipeline integrates with CodeCommit as source.
AWS Lambda
Why wrong: Lambda can be used but is not the primary service.
AWS CodeDeploy
Why wrong: CodeDeploy does not source from CodeCommit.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS CodePipeline
AWS CodePipeline is the correct service because it is a fully managed continuous delivery service that can be configured to automatically start a pipeline execution when a change is pushed to a specific branch in AWS CodeCommit. By setting the source stage to the CodeCommit repository and master branch, CodePipeline triggers subsequent build and deploy actions without manual intervention, enabling a complete CI/CD workflow.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Why it's wrong here
CodeDeploy does not source from CodeCommit.
Common exam traps
The trap here is that candidates confuse individual services (CodeBuild for building, CodeDeploy for deploying) with the orchestration service (CodePipeline) needed to chain them together in response to a source code event.
Detailed technical explanation
Under the hood, CodePipeline uses Amazon CloudWatch Events to detect changes in the CodeCommit repository; when a push to the master branch occurs, CloudWatch Events triggers the pipeline execution. The pipeline then invokes CodeBuild for the build stage and CodeDeploy for the deployment stage, passing artifacts between stages via Amazon S3. In a real-world scenario, teams often add a manual approval step between build and deploy to enforce governance without breaking automation.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
