Amazon Exam DOP-C02 Topic 9 Question 25 Discussion

Actual exam question for Amazon's DOP-C02 exam

Question #: 25
Topic #: 9

A development team uses AWS CodeCommit for version control for applications. The development team uses AWS CodePipeline, AWS CodeBuild. and AWS CodeDeploy for CI/CD infrastructure. In CodeCommit, the development team recently merged pull requests that did not pass long-running tests in the code base. The development team needed to perform rollbacks to branches in the codebase, resulting in lost time and wasted effort.

A DevOps engineer must automate testing of pull requests in CodeCommit to ensure that reviewers more easily see the results of automated tests as part of the pull request review.

What should the DevOps engineer do to meet this requirement?

ACreate an Amazon EventBridge rule that reacts to the pullRequestStatusChanged event. Create an AWS Lambda function that invokes a CodePipeline pipeline with a CodeBuild action that runs the tests for the application. Program the Lambda function to post the CodeBuild badge as a comment on the pull request so that developers will see the badge in their code review.

BCreate an Amazon EventBridge rule that reacts to the pullRequestCreated event. Create an AWS Lambda function that invokes a CodePipeline pipeline with a CodeBuild action that runs the tests for the application. Program the Lambda function to post the CodeBuild test results as a comment on the pull request when the test results are complete.

CCreate an Amazon EventBridge rule that reacts to pullRequestCreated and pullRequestSourceBranchUpdated events. Create an AWS Lambda function that invokes a CodePipeline pipeline with a CodeBuild action that runs the tests for the application. Program the Lambda function to post the CodeBuild badge as a comment on the pull request so that developers will see the badge in their code review.

DCreate an Amazon EventBridge rule that reacts to the pullRequestStatusChanged event. Create an AWS Lambda function that invokes a CodePipeline pipeline with a CodeBuild action that runs the tests for the application. Program the Lambda function to post the CodeBuild test results as a comment on the pull request when the test results are complete.

Ah, the joys of CI/CD! Where the only thing faster than the pipeline is the rate at which developers can break the build.

This is a tough one, but I think I've got it. Option C seems to cover all the bases, with the EventBridge rule reacting to both pullRequestCreated and pullRequestSourceBranchUpdated events. Plus, posting the CodeBuild badge is a nice touch.

Hmm, I'm torn between options B and D. Both of them seem to involve posting the test results as a comment on the pull request, which is exactly what the question is asking for. I'll have to think this one through carefully.

I see your point, but option D reacts to the pullRequestStatusChanged event, which could be more reliable for showing the test results.

I'm not sure why the development team is merging pull requests that didn't pass the long-running tests. That seems like a recipe for disaster! Option B looks like the best way to catch those issues early on.

Wow, this question really tests our understanding of the AWS CodeCommit, CodePipeline, and CodeBuild integration. I think option D is the correct answer, as it directly addresses the requirement to automate testing and provide the results as part of the pull request review.
