Answer: Configure liveness and readiness probes in the Pod specification.
The correct answer is A: Configure liveness and readiness probes in the Pod specification. Configuring liveness and readiness probes ensures that only healthy Pods are serving traffic. Liveness probes help determine if a Pod is running and responsive, whereas readiness probes determine if a Pod is ready to handle requests. These probes help prevent outages during rolling deployments because they ensure that traffic is only routed to fully functional Pods, thereby preventing misconfiguration-related issues in production. Other options either do not apply to GKE or focus on detection rather than prevention.
