[All Professional Cloud DevOps Engineer Questions]

You support a popular mobile game application deployed on Google Kubernetes Engine (GKE) across several Google Cloud regions. Each region has multiple
Kubernetes clusters. You receive a report that none of the users in a specific region can connect to the application. You want to resolve the incident while following Site Reliability Engineering practices. What should you do first?

  • A. Reroute the user traffic from the affected region to other regions that don't report issues.
  • B. Use Stackdriver Monitoring to check for a spike in CPU or memory usage for the affected region.
  • C. Add an extra node pool that consists of high memory and high CPU machine type instances to the cluster.
  • D. Use Stackdriver Logging to filter on the clusters in the affected region, and inspect error messages in the logs.

My answer would be option A, to reroute user traffic from the affected region to other regions that don't report issues, in order to immediately resolve the problem for users and minimize impact, and then use option D, Stackdriver Logging, to investigate the root cause of the issue. This approach aligns with SRE best practices of resolving incidents quickly and then conducting a post-mortem analysis to prevent similar incidents from happening in the future.

Google always aims to first stop the impact of an incident, and then find the root cause (unless the root cause just happens to be identified early on).

Issue is that one region is not serving requests. First thing to resolve is make the application responsive to users as soon as possible affected by this issue. Look into the error logs later.
