SAP-C02 AWS CodePipeline Practice Question
A company runs a static website on Amazon S3 with a custom domain using Amazon Route 53. The website content is updated frequently by multiple developers. The company wants to implement a workflow where updates are automatically tested and deployed. They have existing CI/CD tools that integrate with AWS CodeCommit. The Solutions Architect needs to design a deployment pipeline that rebuilds the website only when changes are pushed to the main branch, and then invalidates the Amazon CloudFront cache if a CloudFront distribution is used. Which solution meets these requirements with the least operational overhead?
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 CodePipeline with a source stage tied to CodeCommit, a build stage using AWS CodeBuild, and a deploy stage that syncs the S3 bucket and invalidates CloudFront.
AWS CodePipeline with a source stage from CodeCommit, a build stage using CodeBuild, and a deploy stage that syncs to S3 and invalidates CloudFront provides a fully managed CI/CD pipeline with minimal operational overhead. Option A is wrong because CloudFormation is for infrastructure provisioning, not for building a deployment pipeline triggered by code pushes. Option B is wrong because S3 event notifications trigger Lambda functions for simple tasks, not for full CI/CD build and deploy workflows. Option D is wrong because Lambda@Edge is for processing requests at edge locations, not for building and deploying static content.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS CloudFormation with a custom resource that triggers a build on CodeCommit push.
Why it's wrong here
Complex and not standard for CI/CD.
- ✗
Configure an S3 event notification to invoke an AWS Lambda function that builds and deploys the website.
Why it's wrong here
Lacks pipeline features like stages and rollback.
- ✓
Use AWS CodePipeline with a source stage tied to CodeCommit, a build stage using AWS CodeBuild, and a deploy stage that syncs the S3 bucket and invalidates CloudFront.
Why this is correct
Fully managed CI/CD pipeline.
- ✗
Use AWS Lambda@Edge to generate the website on the fly and cache at CloudFront.
Why it's wrong here
Not for deployment pipeline.
