Google Professional Cloud DevOps Engineer Question 67
Select 4Google Cloud PlatformYou are tasked with setting up a CI/CD pipeline to manage and deploy infrastructure changes for a Google Kubernetes Engine (GKE) cluster and its associated configurations, including a Cloud Service Mesh. The organization requires that infrastructure changes are version-controlled, reviewed, and tested before deployment. Which steps should you include in the pipeline to meet these requirements?
- A
Store infrastructure configurations in a Git repository to enable version control and code reviews.
- B
Use a CI/CD tool like Cloud Build to integrate with Git and automate the deployment of configuration changes to the GKE cluster.
- C
Manually apply changes to the GKE cluster for faster updates and to avoid automated errors.
- D
Incorporate automated testing for infrastructure changes, such as validating Kubernetes manifests and Service Mesh configurations, before deployment.
- E
Deploy configuration changes directly to the live cluster to reduce delays caused by testing environments.
- F
Implement a staged deployment process, starting with a test environment, before rolling out changes to production.
Show answer and explanation
Correct answers: A, B, D, F
Explanation
To apply CI/CD practices to infrastructure like GKE clusters and Cloud Service Mesh configurations, it is critical to follow a structured and automated approach. This includes version-controlling configurations, using CI/CD tools for automation, performing automated testing, and implementing a staged deployment process. These steps ensure changes are reliable, consistent, and thoroughly tested before impacting production environments, which aligns with the principles of DevOps and the objectives of this certification.
- A. Correct.
Storing infrastructure configurations in a Git repository ensures version control, allows for code reviews, and aligns with CI/CD best practices.
- B. Correct.
Using a CI/CD tool like Cloud Build automates the deployment of changes, reducing manual errors and ensuring consistency.
- C. Incorrect.
Manually applying changes contradicts CI/CD principles, as it introduces the risk of human error and makes the process less scalable.
- D. Correct.
Automated testing for infrastructure changes ensures that misconfigurations are caught early, reducing the risk of deployment failures.
- E. Incorrect.
Deploying changes directly to the live cluster without testing contradicts the best practices of CI/CD, as it increases the risk of introducing issues into production.
- F. Correct.
A staged deployment process is crucial for testing changes in a controlled environment before rolling them out to production, ensuring stability and reliability.
