Refer to the exhibit.
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. A new 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?
- Use placement constraints to control nodes to which the service can be assigned.
- Create the service manually in the central region and set replicas to 0.
- Enable the control flag in the containers of the west and east regions to prevent the service from starting.
- Create a second swarm cluster that is hosted only in the central region.
