SAP-C02 Design for New Solutions Practice Question
A company is designing a CI/CD pipeline for a containerized application using AWS CodePipeline. The application is deployed to Amazon ECS with Fargate. The pipeline must automatically build and test code changes before deploying to production. Which service should be used to build and test the Docker images?
⚠ Common exam trap
Candidates often confuse AWS CodeDeploy's role in ECS deployments with the build and test phase, assuming CodeDeploy handles the entire CI/CD process, when in fact it only handles the deployment step after the image is built and tested by CodeBuild.
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
✓
AWS CodeBuild
AWS CodeBuild is the correct service because it is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages that are ready to deploy. In this scenario, CodeBuild can build the Docker image from a Dockerfile, run unit or integration tests inside the build environment, and then push the image to Amazon ECR, all within the CI/CD pipeline defined in AWS CodePipeline.

Variation 1. A company is designing a new CI/CD pipeline for a containerized application using AWS CodePipeline. The application source code is stored in an Amazon S3 bucket. The pipeline must automatically build a Docker image from the source code and push it to Amazon ECR. Which action should be used as the build provider?
medium- A.AWS CodeDeploy
- B.AWS CodeCommit
- C.Amazon ECS
- ✓ D.AWS CodeBuild
Why D: AWS CodeBuild is the correct build provider because it is a fully managed continuous integration service that can compile source code, run tests, and produce Docker images. It integrates natively with CodePipeline and Amazon ECR, allowing you to define a buildspec.yml file that uses the 'aws ecr get-login-password' command and 'docker build/push' commands to build and push the image directly to ECR.
