Google Professional Cloud Developer Question 246
Select 4Google Cloud PlatformYou are developing a serverless application using Google Cloud Functions. Your team uses a Git-based source control management (SCM) system to manage the codebase. To ensure the code deployed to production is reliable and follows best practices, which steps should you include in your development workflow?
- A
Establish a trunk-based development model to reduce merge conflicts and support continuous integration.
- B
Use branch protection rules to prevent direct commits to the main branch.
- C
Manually deploy code from personal development branches to the production environment without review.
- D
Set up automated tests to run for pull requests before merging them into the main branch.
- E
Enable Git hooks to enforce coding standards during commits.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
To maintain a reliable and efficient development workflow for your serverless application, it is crucial to follow practices such as trunk-based development, branch protection rules, automated testing, and Git hooks. These practices collectively help ensure the codebase remains stable, maintainable, and adheres to quality standards, while manual deployments bypass these safeguards and introduce risks.
- A. Correct.
Establishing a trunk-based development model promotes continuous integration and simplifies collaboration by minimizing long-lived branches and merge conflicts. This aligns with best practices for scalable, reliable development workflows.
- B. Correct.
Branch protection rules prevent unauthorized or unsafe changes from being pushed directly to the main branch, ensuring only reviewed and tested code is deployed.
- C. Incorrect.
Manually deploying code from personal branches to production is error-prone and bypasses important review, testing, and approval processes. This is not a best practice.
- D. Correct.
Automated tests for pull requests help identify bugs early and ensure the quality of the code before merging into the main branch, reducing the risk of deploying faulty code.
- E. Correct.
Git hooks can enforce coding standards and other checks during commits, ensuring consistent and high-quality code is contributed to the repository.
