Amazon DOP-C02 Exam - 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.

Is it really necessary to automate this? Seems like extra work.

I lean towards option C because it covers both the creation and updates of the pull request, which seems more comprehensive for testing.

I’m a bit confused about the difference between the pullRequestStatusChanged and pullRequestCreated events. I feel like both could be relevant.

I think we practiced a similar question where we had to automate testing in CodePipeline. I feel like option B makes sense since it focuses on the pull request creation.

I remember we discussed using EventBridge for triggering actions based on events, but I'm not sure which event to choose here.

This is a great question to test our understanding of AWS CodePipeline and CodeBuild. I think Option A is the way to go - reacting to the pullRequestStatusChanged event and posting the test results as a comment seems like the most straightforward approach.

Hmm, I'm a bit confused by the different event types mentioned in the options. I'll need to review the AWS documentation on CodeCommit events to make sure I understand the differences before I can decide which option is best.

This seems like a straightforward question. I think the key is to automate the testing process and make the results visible to the reviewers. Option B looks like the best approach to me.

I like the idea of using EventBridge to trigger the testing pipeline. That way, the tests will run automatically whenever a new pull request is created or updated. Option C seems like a good comprehensive solution.

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

D) Create 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.

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'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.
