Answer-first summary for fast verification
Answer: Configure Health Checks to continuously verify if the instance is available.
Option A is incorrect because Uptime Checks are used to verify if an application responds or is reachable, not specifically for load balancing purposes. Option B is correct as Health Checks are utilized by the load balancer to determine if the backend is reachable and responsive to traffic. Option C is incorrect since Readiness Probes are used by Kubernetes to check if pods are ready to receive traffic, not for load balancer health checks. Option D is incorrect because Liveness Probes are used by Kubernetes to check if a pod is in the running state and to restart it if it's not, which is unrelated to load balancer health checks.
