A cluster consists of 2 base boot addresses per node. Each boot address can contact the other node in the cluster but is not externally routable. There is one service IP address in cluster which is externally routable.
The external network experienced a problem where the service IP could not be contacted by the users, but the base boot addresses were still able to send heartbeat packets between the cluster nodes. The resource groups did not failover to the other node where there was no network problem.
How can the administrator ensure that the resource groups failover when the service address is not contactable on a node?
A. Create a custom application monitor.
B. Create a process application monitor.
C. Configure a persistent IP address on each node.
D. Configure a post-event script to the fail_interface event.
