AWS Certified Developer – Associate — Question 190

A developer is writing a new serverless application for a company. Several other developers must collaborate on the code for this application, and the company expects frequent changes to the code. The developer needs to deploy the code from source control to AWS Lambda with the fewest number of manual steps.

Which strategy for the build and deployment should the developer use to meet these requirements?

Answer options

• A. Build the code locally, and then upload the code into the source control system. When a release is needed, run AWS CodePipeline to extract the uploaded build and deploy the resources.
• B. Use the AWS Serverless Application Model (AWS SAM) CLI to build and deploy the application from the developer's local machine with the latest version checked out locally.
• C. Use AWS CodeBuild and AWS CodePipeline to invoke builds and corresponding deployments when configured source controlled branches have pull requests merged into them
• D. Use the Lambda console to upload a .zip file of the application that is created by the AWS Serverless Application Model (AWS SAM) CLI build command.

Correct answer: C

Explanation

The correct answer is C because using AWS CodeBuild and AWS CodePipeline allows for automated builds and deployments when changes are made in source control, which suits the requirement for frequent updates. Option A involves manual steps for uploading code, B requires local execution which may not facilitate collaboration as effectively, and D does not support automation in deployments.
