Your team has created an application that is hosted on a GKE cluster. You need to connect the application to a REST service that is deployed in two GKE clusters in two different regions. How should you set up the connection and health checks? (Choose two.)

A. Use Cloud Service Mesh with sidecar proxies to connect the application to the REST service. B. Use Cloud Service Mesh with proxyless gRPC to connect the application to the REST service. C. Configure the REST service's firewall to allow health checks originating from the GKE service’s IP ranges. D. Configure the REST service's firewall to allow health checks originating from the GKE control plane’s IP ranges. E. Configure the REST service's firewall to allow health checks originating from the GKE check probe’s IP ranges.
