Answer-first summary for fast verification
Answer: Implement Health Checks to continuously verify the instance's availability.
The correct answer is **Health Checks**, as they are utilized by the load balancer to assess whether the backend is accessible and can handle traffic. **Why Other Options are Incorrect:** - **Readiness Probe**: Used by Kubernetes to determine if pods are prepared to accept traffic. - **Liveness Probe**: Employed by Kubernetes to check if a pod is operational; if not, it restarts the pod. - **Uptime Check**: Designed to verify if an application is responsive or reachable. For further reference, consult the documentation on [Create public uptime checks](https://cloud.google.com/monitoring/uptime-checks) and [Health checks](https://cloud.google.com/load-balancing/docs/health-checks).
