Google Cloud Professional Cloud DevOps Engineer — Question 27

You are running an experiment to see whether your users like a new feature of a web application. Shortly after deploying the feature as a canary release, you receive a spike in the number of 500 errors sent to users, and your monitoring reports show increased latency. You want to quickly minimize the negative impact on users. What should you do first?

Answer options

• A. Roll back the experimental canary release.
• B. Start monitoring latency, traffic, errors, and saturation.
• C. Record data for the postmortem document of the incident.
• D. Trace the origin of 500 errors and the root cause of increased latency.

Correct answer: A

Explanation

The best first step is to roll back the experimental canary release to quickly mitigate the negative user experience caused by the errors and latency. While monitoring and recording data are important, they do not address the immediate issue that users are facing. Tracing the errors may help in understanding the problem, but it won't provide a quick solution to reduce the impact on users.
