GCP Professional Cloud Architect Practice Question

Your e-commerce platform runs in a single-region Google Kubernetes Engine (GKE) cluster backed by a Cloud SQL database. Business leadership mandates that, if the primary region becomes unavailable, customer transactions must resume within 15 minutes and no more than a few minutes of data can be lost. Budget owners will not approve the ongoing expense of a fully active/active deployment. Which disaster-recovery pattern should you recommend for the secondary region?

  • Multi-zone high availability: add additional GKE nodes and Cloud SQL replicas in separate zones of the same region.

  • Cold standby: store backups in Cloud Storage and recreate the GKE cluster and Cloud SQL instance only after a disaster occurs.

  • Hot active-active: run fully sized GKE and Cloud SQL instances in two regions behind global load balancing with live traffic distribution.

  • Warm standby: continuously replicate Cloud SQL to another region and keep a scaled-down GKE cluster ready to scale up during failover.
