Quick Answer
The answer is using AWS CodePipeline with a source stage that polls CodeCommit for changes and triggers a build stage, along with configuring AWS CodeBuild to automatically run tests when a pull request is created in CodeCommit. These are valid strategies because they enforce continuous integration by automatically building and testing code upon every commit or pull request, ensuring that only validated code is merged into the main branch. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this concept tests your understanding of how to automate the integration pipeline using event-driven triggers versus manual polling, with a common trap being to confuse manual approval gates with CI triggers. A key memory tip is to remember that CI is about automation before merge, not after—so think "CodePipeline + CodeBuild = auto-test on push or PR."
This DOP-C02 practice question tests your understanding of sdlc automation. 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.
Which of the following are valid strategies for implementing continuous integration in AWS? (Choose two.)
Set up AWS CodeDeploy to trigger a build every time a commit is pushed to a repository.
Why wrong: CodeDeploy is for deployment, not building or testing.
Use AWS CloudFormation to create a stack that runs tests every time a new commit is pushed.
Why wrong: CloudFormation is for infrastructure as code, not for running tests.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure AWS CodeBuild to automatically run tests when a pull request is created in CodeCommit.
Option A is correct because AWS CodeBuild can be configured to automatically run tests when a pull request is created in CodeCommit using a webhook or event rule. This enables continuous integration by validating code changes before merging, ensuring that only tested code is integrated into the main branch.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Set up AWS CodeDeploy to trigger a build every time a commit is pushed to a repository.
Why it's wrong here
CodeDeploy is for deployment, not building or testing.
Use AWS CloudFormation to create a stack that runs tests every time a new commit is pushed.
Why it's wrong here
CloudFormation is for infrastructure as code, not for running tests.
Option-by-option analysis
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.
Why this is wrong here
CodeDeploy is for deployment, not building or testing.
Why this is wrong here
CloudFormation is for infrastructure as code, not for running tests.

Common exam traps
The trap here is confusing deployment services (CodeDeploy) and infrastructure provisioning (CloudFormation) with CI build triggers, leading candidates to select options that sound plausible but lack the specific capability to initiate a build or run tests.
Detailed technical explanation
Under the hood, AWS CodeBuild integrates with CodeCommit via event-based triggers (e.g., Amazon CloudWatch Events or CodeCommit repository triggers) that invoke a build project on pull request creation or code push. CodePipeline, on the other hand, uses a source stage that polls CodeCommit for changes (or uses webhooks) and then passes the artifact to a build stage, enabling a fully managed CI/CD pipeline. In real-world scenarios, combining CodePipeline with CodeBuild allows for parallel test execution and artifact versioning, which is essential for maintaining code quality in multi-branch workflows.
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.
