A Docker swarm cluster is configured to load balance services across data centers in three different geographical regions west central and east. The cluster has three manager nodes and three worker nodes Anew service named cisco.devnet is being deployed. The service has these design requirements
• All containers must be hosted only on nodes in the central region
• The service must run only on nodes that are ineligible for the manager role Which approach fulfills the requirements?
Create a second swarm cluster that is hosted only in the central region.
Create the service manually in the central region and set replicas to 0.
Use placement constraints to control nodes to which the service can be assigned.
Enable the control flag in the containers of the west and east regions to prevent the service from starting
Refer to the exhibit.
Refer to the exhibit A Docker swarm service is currently running m a local data center The service is hosting an HTML website it the container fads then the service becomes unavailable The design must meet these requirements
• The service must be highly available and resilient against a data center outage.
• 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.)
Create another swarm cluster within a data center and deploy a secondary instance of the service.
Create another node in the swarm duster to scale the service across the nodes over two replicas.
Configure an external load balancer to route requests to the swarm service by using session persistence
Scale the Docker swarm service to 2 and set endpoint-mode to DNSRR instead of the default value of VIP
Configure a routing mesh to route requests to the swarm service by using NAT on the network side
