Exam question from Amazon's AWS DevOps Engineer Professional
Question #: 61
Topic #: 1
[All AWS DevOps Engineer Professional Questions]

A company wants to use AWS development tools to replace its current bash deployment scripts. The company currently deploys a LAMP application to a group of
Amazon EC2 instances behind an Application Load Balancer (ALB). During the deployments, the company unit tests the committed application, stops and starts services, unregisters and re-registers instances with the load balancer, and updates file permissions. The company wants to maintain the same deployment functionality through the shift to using AWS services.
Which solution will meet these requirements?

  • A. Use AWS CodeBuild to test the application. Use bash scripts invoked by AWS CodeDeploy's appspec.yml file to restart services, and deregister and register instances with the ALB. Use the appspec.yml file to update file permissions without a custom script.
  • B. Use AWS CodePipeline to move the application from the AWS CodeCommit repository to AWS CodeDeploy. Use CodeDeploy's deployment group to test the application, unregister and re-register instances with the ALB, and restart services. Use the appspec.yml file to update the permissions without a custom script.
  • C. Use AWS CodePipeline to move the application source code from the AWS CodeCommit repository to AWS CodeDeploy. Use CodeDeploy to test the application. Use CodeDeploy's appspec.yml file to restart services and update permissions without a custom script. Use AWS CodeBuild to unregister and re- register instances with the ALB.
  • D. Use AWS CodePipeline to trigger AWS CodeBuild to test the application. Use bash scripts invoked by AWS CodeDeploy's appspec.yml file to restart services. Unregister and re-register the instances in the AWS CodeDeploy deployment group with the ALB. Update the appspec.yml file to update file permissions without a custom script.

You can test with codedeploy: https://aws.amazon.com/blogs/devops/how-to-test-and-debug-aws-codedeploy-locally-before-you-ship-your-code/#:~:text=You%20can%20test%20application%20code,local%20server%20or%20EC2%20instance.

You can test application **code packages** (NOT application) on any machine that has the CodeDeploy agent installed before you deploy it through the service. Likewise, to debug locally, you just need to install the CodeDeploy agent on any machine, including your local server or EC2 instance. Where as CodeBuild compiles your source code, runs unit tests, and produces artifacts that are ready to deploy. The correct answer is D

Since the company wants to use AWS development tools to replace its current bash deployment scripts I don't see any point to choose D.

I think it is better to assume that CodeDeploy agent is installed on EC2 it order to test the code with CodeDeploy than to go against the main requirement for replacement its current bash scripts, so that's why I marked B as an answer.

D is the most appropriate. However, the company wants to replace bash deployment scripts. D suggests using them. hence B serves the company's requirements.

Selected Answer: B
Option B is the most appropriate solution because it uses AWS CodePipeline to move the application from the AWS CodeCommit repository to AWS CodeDeploy, which can test the application, unregister and re-register instances with the ALB, and restart services. The appspec.yml file can be used to update the permissions without a custom script.

Selected Answer: D
Though Codedeploy can be used for unit testing applications, it requires Codedeploy agents installed on the machine (https://aws.amazon.com/blogs/devops/how-to-test-and-debug-aws-codedeploy-locally-before-you-ship-your-code/#:~:text=You%20can%20test%20application%20code,local%20server%20or%20EC2%20instance). However, the correct approach is to use Codebuild for unit testing. A: Incorrect: There is no deployment pipeline. Uses only Codebuild B and C: Incorrect: Codebuild is used for testing - not Codedeploy D: Correct. Has Codepipeline, Codebuild for unit testing and Codedeploy

If the question doesn't say the agent is installed, you assume it is not.
