Google Cloud Professional Cloud DevOps Engineer — Question 60

You support a web application that is hosted on Compute Engine. The application provides a booking service for thousands of users. Shortly after the release of a new feature, your monitoring dashboard shows that all users are experiencing latency at login. You want to mitigate the impact of the incident on the users of your service. What should you do first?

Answer options

• A. Roll back the recent release.
• B. Review the Stackdriver monitoring.
• C. Upsize the virtual machines running the login services.
• D. Deploy a new release to see whether it fixes the problem.

Correct answer: A

Explanation

Rolling back the recent release is the most effective first step as it immediately reverts to the previous stable version, potentially eliminating the latency issue. Reviewing Stackdriver monitoring or upsizing virtual machines may provide insights or improvements, but they do not directly address the immediate problem. Deploying a new release could introduce further complications instead of resolving the existing issue.
