Google Cloud Professional Cloud Architect — Question 45

Your customer is receiving reports that their recently updated Google App Engine application is taking approximately 30 seconds to load for some of their users.
This behavior was not reported before the update.
What strategy should you take?

Answer options

• A. Work with your ISP to diagnose the problem
• B. Open a support ticket to ask for network capture and flow data to diagnose the problem, then roll back your application
• C. Roll back to an earlier known good release initially, then use Stackdriver Trace and Logging to diagnose the problem in a development/test/staging environment
• D. Roll back to an earlier known good release, then push the release again at a quieter period to investigate. Then use Stackdriver Trace and Logging to diagnose the problem

Correct answer: C

Explanation

The correct answer is C because it suggests rolling back to a stable version first, which can quickly resolve the performance issue, and then using Stackdriver Trace and Logging to identify the underlying problem in a controlled environment. Options A and B do not address the immediate need to restore functionality, and option D could lead to the same issue recurring without proper diagnosis.
