Google Professional Cloud DevOps Engineer Question 54
Select 3Google Cloud PlatformYou are a DevOps Engineer designing a CI/CD pipeline for a high-traffic web application deployed on Google Kubernetes Engine (GKE). The pipeline must ensure fast feedback for developers, automated testing, and safe deployment practices. Which of the following designs should you incorporate into your CI/CD pipeline to meet these requirements?
- A
Use parallel stages in the CI pipeline to execute unit tests and integration tests simultaneously.
- B
Implement a canary deployment strategy to gradually roll out changes to a subset of users before full deployment.
- C
Disable automated rollback mechanisms to reduce unnecessary deployments.
- D
Integrate static code analysis tools into the CI pipeline to detect potential code quality issues early.
- E
Run all CI/CD stages sequentially to simplify troubleshooting.
Show answer and explanation
Correct answers: A, B, D
Explanation
To design an effective CI/CD pipeline for a high-traffic application on GKE, it is essential to prioritize fast feedback, automated testing, and safe deployment practices. Using parallel stages accelerates feedback for developers, static code analysis ensures code quality, and canary deployments provide a controlled mechanism for rolling out changes. Avoiding sequential stages and disabling rollback mechanisms would compromise the pipeline's speed and reliability.
- A. Correct.
Using parallel stages helps speed up the CI pipeline by running unit tests and integration tests simultaneously, ensuring faster feedback for developers.
- B. Correct.
Canary deployments allow for safer rollouts by exposing changes to a small percentage of users first, reducing the impact of potential issues.
- C. Incorrect.
Disabling automated rollback mechanisms is not recommended, as it can lead to prolonged outages or manual intervention in case of deployment failures.
- D. Correct.
Static code analysis tools help identify code quality issues early in the pipeline, reducing the risk of introducing bugs into production.
- E. Incorrect.
Running all stages sequentially slows down the CI/CD process unnecessarily and does not prioritize fast feedback, which is crucial for developers.
