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.
