Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 242 discussion

A. The change was not made in the main branch of the AWS CodeCommit repository: In this pipeline setup, if the change was made in a branch other than the main branch, it would not trigger the pipeline, and therefore, AWS CodeDeploy wouldn't deploy the updated application. B. One of the earlier stages in the pipeline failed and the pipeline has terminated: If one of the preceding stages in the pipeline failed, it would prevent the subsequent stages, including AWS CodeDeploy, from being executed.

AB is the correct answer.

A. The change was not made in the main branch of the AWS CodeCommit repository. If the change to the application's source code was not made in the main branch (or the branch that triggers the pipeline), AWS CodePipeline would not detect the change and therefore would not initiate the deployment process. It's crucial that changes are made in the correct branch that is configured to trigger the pipeline. B. One of the earlier stages in the pipeline failed and the pipeline has terminated. If any stage in AWS CodePipeline fails (such as a failure in the test or build stages in AWS CodeBuild), the pipeline stops and does not proceed to the deployment stage. It is common for pipelines to be configured to halt on failure to prevent the deployment of potentially faulty code.

AB is correct - there have been no changes, so someone either merged code into the wrong branch (not triggering the pipeline) or it failed at an earlier stage. Other options dont make sence given the scenario

The delivery pipeline is triggered by changes to the main branch - so new code change should have triggered this but this cause errors for some reasons and option C

AB the key word is "The pipeline has been operating successfully for several months and there have been no modifications." So the "D. The codePipeline is incorrectly configured" is incorrect, because if the configuration is incorrect, it won't have been operating successfully for several months.

B. One of the earlier stages in the pipeline failed and the pipeline has terminated. D. The AWS CodePipeline is incorrectly configured and is not invoking AWS CodeDeploy.
