• The service must be accessible from a single URL

• The HTTP session must remain on the server from which the original request was sent

• 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
D . Scale the Docker swarm service to 2 and set endpoint-mode to DNSRR instead of the default value of VIP
