Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 69 discussion

The correct answer is B and E The buildspec file is a collection of build commands and related settings, in YAML format, that CodeBuild uses to run a build. By adding the build and test commands to the buildspec file, the developer can ensure that these commands are executed as part of the build process. Option E will ensure that the CodeBuild project is triggered as part of the pipeline and that the unit tests are run in the new deployment environment.

For those who just skim the question, keyword between D and E is "unit tests run in the new deployment environment.", which signifies a new stage should be created instead of just adding an action.

AWS CodeBuild is specifically designed for building and testing code in CI/CD pipelines. The buildspec file is where the developer can specify commands to build and run unit tests for the application package. A new stage after the source stage ensures that the unit tests run on the package retrieved from GitHub.

BE is the correct answer.

E. Add a new stage to the pipeline after the source stage: This is the correct step. The developer should add a new stage to the pipeline specifically for building and testing the code. Within this stage, an action should be added that specifies the AWS CodeBuild project (created in step B) as the action provider. The source artifact (code fetched from GitHub) should be specified as the action's input artifact. So, the combination of steps that should be taken next to meet these requirements with the least overhead are: B. Create an AWS CodeBuild project. Add the repository package's build and test commands to the project's buildspec. E. Add a new stage to the pipeline after the source stage. Add an action to the new stage. Specify the newly created CodeBuild project as the action provider. Specify the source artifact as the action's input artifact.

Choosing D as that is the least overhead. There is already a stage and you need to add an action test
