Your team has created an application that is hosted on a Google Kubernetes Engine (GKE) cluster. You need to connect the application to a legacy REST service that is deployed in two GKE clusters in two different regions. You want to connect your application to the target service in a way that is resilient. You also want to be able to run health checks on the legacy service on a separate port. How should you set up the connection? (Choose two.)

A. Use Traffic Director with a sidecar proxy to connect the application to the service. B. Use a proxyless Traffic Director configuration to connect the application to the service. C. Configure the legacy service's firewall to allow health checks originating from the proxy. D. Configure the legacy service's firewall to allow health checks originating from the application. E. Configure the legacy service's firewall to allow health checks originating from the Traffic Director control plane.
