GCP Professional Cloud Architect Practice Question

An e-commerce platform running on a multi-zone GKE cluster started showing intermittent 5xx errors during the checkout flow shortly after a canary rollout finished. The on-call engineer has already verified the alerts, collected pod logs and cluster metrics, and confirmed that the failures correlate with a spike in request latency. Following a systematic troubleshooting methodology, which next action should they take to narrow down the root cause most effectively?

  • Open a P1 case with Google Cloud Support and attach the current production logs for investigation.

  • Roll back the canary deployment to the previous container image to restore service as quickly as possible.

  • Create a new Cloud Monitoring uptime check for the checkout endpoint and set an alerting policy on non-200 responses.

  • Reproduce the checkout workload in a staging cluster that mirrors production traffic and capture Cloud Trace spans during the test.
