   A company is deploying a microservices application across a cluster of five Linux servers.

Which approach satisfies these requirements?

   • AUse a container orchestration platform such as Kubernetes to define deployments and services that handle placement, self-healing, and service discovery.
   • BInstall Docker Compose on each server and run the same compose file locally to start all 12 services on every node.
   • CConfigure each container with a static IP address and use an external load balancer to route traffic between the five servers.
   • DWrite a shell script that uses the docker run command on each server to start the containers and update /etc/hosts files with service names.
