High Availability — Google Cloud Professional Cloud Architect Practice Questions

High availability refers to designing systems so that they continue operating despite component failures, and it is a core design principle tested throughout the Professional Cloud Architect exam. Google Cloud provides HA options at multiple layers, including multi-zonal and multi-regional deployments for Compute Engine, Cloud SQL, Cloud Spanner, and GKE, as well as global load balancing to distribute traffic away from unhealthy backends. Architects must know how to quantify availability targets using SLAs and SLOs, and how to select services and configurations that meet those targets. The exam frequently asks you to identify the minimum architecture change needed to eliminate a single point of failure.
