Google Cloud Professional Cloud DevOps Engineer — Question 89

You need to build a CI/CD pipeline for a containerized application in Google Cloud. Your development team uses a central Git repository for trunk-based development. You want to run all your tests in the pipeline for any new versions of the application to improve the quality. What should you do?

Answer options

• A. 1. Install a Git hook to require developers to run unit tests before pushing the code to a central repository. 2. Trigger Cloud Build to build the application container. Deploy the application container to a testing environment, and run integration tests. 3. If the integration tests are successful, deploy the application container to your production environment, and run acceptance tests.
• B. 1. Install a Git hook to require developers to run unit tests before pushing the code to a central repository. If all tests are successful, build a container. 2. Trigger Cloud Build to deploy the application container to a testing environment, and run integration tests and acceptance tests. 3. If all tests are successful, tag the code as production ready. Trigger Cloud Build to build and deploy the application container to the production environment.
• C. 1. Trigger Cloud Build to build the application container, and run unit tests with the container. 2. If unit tests are successful, deploy the application container to a testing environment, and run integration tests. 3. If the integration tests are successful, the pipeline deploys the application container to the production environment. After that, run acceptance tests.
• D. 1. Trigger Cloud Build to run unit tests when the code is pushed. If all unit tests are successful, build and push the application container to a central registry. 2. Trigger Cloud Build to deploy the container to a testing environment, and run integration tests and acceptance tests. 3. If all tests are successful, the pipeline deploys the application to the production environment and runs smoke tests

Correct answer: D

Explanation

Option D is correct because it establishes a thorough CI/CD process by automatically triggering unit tests upon code push, ensuring early detection of issues. The other options either lack the initial unit test trigger or do not adequately integrate the testing phases before deployment, which could lead to potential problems in the production environment.
