DOP-C02 AWS CI/CD service Practice Question
Which AWS service is primarily used to automate the building, testing, and deployment of code changes to AWS infrastructure based on a defined release process?
⚠ Common exam trap
Test-takers frequently confuse the individual services (CodeBuild for building, CodeDeploy for deploying) with the orchestrator (CodePipeline) that ties them together, leading them to select a service that performs only one part of the process rather than the full automation of the release process.

Correct answer & explanation
✓
AWS CodePipeline
AWS CodePipeline is the correct service because it is a fully managed continuous delivery service that orchestrates the building, testing, and deployment of code changes through a defined release process. It integrates with source control (e.g., CodeCommit, GitHub), build services (e.g., CodeBuild), and deployment services (e.g., CodeDeploy) to automate the entire pipeline from commit to production.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS CodeCommit
Why it's wrong here
AWS CodeCommit is a fully managed source control service that hosts private Git repositories. It acts as the source stage in a CI/CD workflow, storing code and versioning it, but it does not orchestrate, build, or deploy anything. Its role is limited to repository management, so while it is part of the CI/CD ecosystem, it is not the CI/CD service itself.
- ✓
AWS CodePipeline
Why this is correct
AWS CodePipeline is a fully managed continuous delivery service that automates the entire release process, from source through build, test, and deployment. It orchestrates the pipeline by connecting multiple stages, such as pulling code from CodeCommit, invoking CodeBuild, and triggering CodeDeploy, along with integrations for third-party tools like Jenkins or GitHub. This end-to-end automation makes it the central CI/CD service in AWS.
- ✗
AWS CodeBuild
Why it's wrong here
AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs unit tests, and produces deployable artifacts. It focuses exclusively on the build phase, executing build commands in a managed environment, and does not manage the broader pipeline flow, such as triggering deployments or coordinating multiple stages. Therefore, it is a component used within a CI/CD pipeline, not the CI/CD orchestration service.
- ✗
AWS CodeDeploy
Why it's wrong here
AWS CodeDeploy is a fully managed deployment service that automates the release of applications to environments like Amazon EC2, AWS Lambda, or on-premises instances. It handles the deployment stage, including rolling updates and traffic shifting, but it does not manage the source, build, or test stages of a CI/CD workflow. Because its scope is limited to deploying artifacts, it is not the overarching CI/CD service.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The DOP-C02 exam frequently reuses these exact scenarios with slightly different constraints.
