This DVA-C02 practice question tests your understanding of deployment. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 uses AWS CloudFormation to manage infrastructure. The development team wants to implement a CI/CD pipeline that automatically updates a CloudFormation stack when code is pushed to a CodeCommit repository. The pipeline should also run tests before deploying. Which THREE services should be used together to achieve this? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS CodeBuild
AWS CodeBuild is correct because it can compile source code, run tests, and produce artifacts that are ready for deployment. In this CI/CD pipeline, CodeBuild executes the test suite after code is pushed to CodeCommit, ensuring that only validated code proceeds to update the CloudFormation stack.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
AWS CodeBuild
Why this is correct
CodeBuild runs tests and builds the project.

✗
Amazon CloudWatch Events
Why it's wrong here
CloudWatch Events can trigger the pipeline, but CodePipeline itself handles the trigger from CodeCommit.
✗
AWS CodeDeploy
Why it's wrong here
CodeDeploy is for application deployment, not for CloudFormation stack updates.
✓
AWS CodePipeline
Why this is correct
CodePipeline orchestrates the pipeline stages including source, build, and deploy.

✓
AWS CodeCommit
Why this is correct
CodeCommit is the source repository for the code.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse AWS CodeDeploy with CloudFormation stack updates, but CodeDeploy handles application-level deployments (e.g., code to instances) while CloudFormation manages infrastructure provisioning and updates, so CodeDeploy is not used for stack updates in this context.
Detailed technical explanation
How to think about this question
Under the hood, CodePipeline orchestrates the sequence of actions, invoking CodeBuild for the test stage and CloudFormation for the deployment stage. CodeBuild runs in a managed environment with customizable buildspec.yml files, and it can integrate with CloudFormation by using the AWS CLI or SDK to trigger stack updates, but the actual stack update is performed by CloudFormation as a separate action in the pipeline. A real-world scenario might involve a multi-branch pipeline where CodeBuild runs unit tests and integration tests in parallel before a CloudFormation change set is created and executed.
KKey Concepts to Remember

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→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.
