Problem Statement
You are running two Kubernetes clusters in different regions for high availability. One region faces a full outage. Which of the following strategies supports traffic fail-over to the healthy region with minimal manual intervention?
Explanation
In a multi-region Kubernetes setup you’d typically use a global load-balancer (for example a cloud provider’s global LB or DNS-based load-balancing) with health probes to detect regional cluster health and route traffic automatically to the healthy region. This minimises manual intervention and supports resilient fail-over. Scenario-based interviews expect you to understand cross-region availability and traffic routing. :contentReference[oaicite:2]{index=2}
