- A
Use AWS CodeDeploy to deploy the application to EC2 instances.
Why wrong: Serverless application does not use EC2.
- B
Use AWS CodeCommit as a deployment action.
Why wrong: CodeCommit is a source, not an action.
- C
Use AWS CodeBuild to run unit tests and package the application.
CodeBuild is ideal for build and test.
- D
Use AWS Lambda to run integration tests.
Why wrong: Lambda can run tests but is not a pipeline action.
- E
Use AWS CloudFormation to create or update the stack.
CloudFormation manages infrastructure.

DVA-C02 Deployment Practice Question
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 developer is designing a CI/CD pipeline for a serverless application using AWS CodePipeline. The pipeline must automatically build and deploy the application when changes are pushed to a CodeCommit repository. The application uses AWS CloudFormation for infrastructure provisioning. Which TWO actions should the developer include in the pipeline?
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
✓
Use AWS CodeBuild to run unit tests and package the application.
Option C is correct because AWS CodeBuild can compile source code, run unit tests, and produce deployment artifacts, which is a standard build phase in a CI/CD pipeline. Option E is correct because AWS CloudFormation is the native AWS service for provisioning and updating infrastructure as code, making it the appropriate deployment action for a serverless application defined in templates.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS CodeDeploy with CloudFormation for serverless deployments, not realizing that CodeDeploy is for EC2/on-premises and CloudFormation is the correct service for provisioning serverless infrastructure.
Detailed technical explanation
How to think about this question
In a CodePipeline, the build stage typically uses CodeBuild to run commands defined in a buildspec.yml file, which can include unit tests and artifact packaging. The deploy stage for a serverless application using CloudFormation can use a CloudFormation deployment action with a change set execution, allowing the pipeline to create or update stacks incrementally. A real-world scenario might involve a monorepo where CodeBuild filters changes to only trigger builds for modified services, reducing pipeline execution time.
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.
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.
