GCP Associate Cloud Engineer Practice Question

Your team runs a business-critical API on Google Kubernetes Engine. During a recent zone-wide outage, the application became unreachable because the cluster's control plane and nodes were hosted in a single zone. Management mandates that the new production cluster must continue to operate even if an entire zone in the region fails, while keeping operational effort low. Which statement correctly describes how a regional GKE cluster meets this requirement out of the box?

  • Regional clusters create a second control-plane replica only when the primary becomes unhealthy, which can introduce several minutes of downtime during a zone failure.

  • The control plane is automatically replicated across three zones in the region, and the default node pool is evenly distributed across those zones, providing zone-level fault tolerance without extra configuration.

  • High availability for a regional cluster is achieved by placing Cloud Load Balancing in front of multiple single-zone clusters; the regional control plane itself remains single-zone.

  • A regional cluster deploys a single control-plane instance per region; you must manually create separate node pools in each zone to survive a zone outage.
