- A
Use AWS CloudFormation with a template to deploy the infrastructure.
CloudFormation can deploy Lambda and API Gateway resources.
- B
Create a CodeCommit repository to store the source code.
CodeCommit is a source control service that integrates with CodePipeline.

Question 587 of 1,616
How to Build a CI/CD Pipeline for Serverless Applications using CodePipeline, CloudFormation, and CodeBuild
This DVA-C02 practice question tests your understanding of development with aws services. 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 creating a CI/CD pipeline for a serverless application using AWS CodePipeline. The application includes Lambda functions and an API Gateway REST API. The pipeline should automatically deploy changes when code is pushed to a Git repository. Which THREE actions are required to set this up? (Choose THREE.)
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 CloudFormation with a template to deploy the infrastructure.
Option A is correct because AWS CloudFormation is the primary infrastructure-as-code service used to define and deploy serverless resources like Lambda functions and API Gateway REST APIs. In a CodePipeline, a CloudFormation deployment action can automatically create or update the stack based on a template, ensuring consistent and repeatable infrastructure provisioning.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse CodeDeploy as the default deployment service for Lambda, but for serverless applications using CloudFormation, the pipeline should use CloudFormation deployment actions rather than CodeDeploy, unless advanced deployment strategies like canary releases are explicitly required.
Detailed technical explanation
How to think about this question
Under the hood, CodePipeline orchestrates stages sequentially, and for serverless deployments, the CloudFormation deployment action uses change sets to apply updates safely, which can include Lambda function code updates via the AWS::Lambda::Version resource. In a real-world scenario, using CodeBuild to run unit tests and package the application (e.g., creating a deployment artifact with a SAM template) ensures that only validated code reaches the deployment stage, preventing broken infrastructure updates.
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.

Same concept, more angles
1 more ways this is tested on DVA-C02
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A developer is creating a CI/CD pipeline for a serverless application using AWS CodePipeline. The application consists of an AWS Lambda function, an Amazon API Gateway REST API, and an Amazon DynamoDB table. Which action should the developer take to automate the deployment of the API Gateway updates?
easy- A.Use AWS Lambda to update the API Gateway configuration.
- B.Store the API Gateway Swagger file in Amazon S3 and trigger a deployment.
- ✓ C.Use AWS CloudFormation to define and deploy the API Gateway.
- D.Use AWS CodeBuild to compile and deploy the API Gateway configuration.
Why C: Option C is correct because AWS CloudFormation provides infrastructure as code (IaC) capabilities that allow you to define the entire API Gateway configuration, including resources, methods, integrations, and deployment stages, in a template. When integrated with CodePipeline, CloudFormation can automatically create or update the API Gateway and trigger a deployment as part of the CI/CD pipeline, ensuring consistent and repeatable deployments without manual intervention.
