Exam AWS DevOps Engineer Professional topic 1 question 112 discussion

Exam question from Amazon's AWS DevOps Engineer Professional
Question #: 112
Topic #: 1
[All AWS DevOps Engineer Professional Questions]

A development team manually builds an artifact locally and then places it in an Amazon S3 bucket. The application has a local cache that must be cleared when a deployment occurs. The team executes a command to do this, downloads the artifact from Amazon S3, and unzips the artifact to complete the deployment.

A DevOps team wants to migrate to a CI/CD process and build in checks to stop and roll back the deployment when a failure occurs. This requires the team to track the progression of the deployment.

Which combination of actions will accomplish this? (Choose three.)

  • A. Allow developers to check the code into a code repository. Using Amazon CloudWatch Events, on every pull into master, trigger an AWS Lambda function to build the artifact and store it in Amazon S3.
  • B. Create a custom script to clear the cache. Specify the script in the Beforelnstall lifecycle hook in the AppSpec file.
  • C. Create user data for each Amazon EC2 instance that contains the clear cache script. Once deployed, test the application. If it is not successful, deploy it again.
  • D. Set up AWS CodePipeline to deploy the application. Allow developers to check the code into a code repository as a source for the pipeline.
  • E. Use AWS CodeBuild to build the artifact and place it in Amazon S3. Use AWS CodeDeploy to deploy the artifact to Amazon EC2 instances.
  • F. Use AWS Systems Manager to fetch the artifact from Amazon S3 and deploy it to all the instances.
