• Failure of the server must force the client to reconnect

Which two design approaches must be used to meet the requirements? (Choose two.)
A . Create another swarm cluster within a data center and deploy a secondary instance of the service.
B. Create another node in the swarm duster to scale the service across the nodes over two replicas.
C. Configure an external load balancer to route requests to the swarm service by using session persistence
