Continuous availability is required for an application in a two-node cluster. There is one rotating resource group in the cluster, and the nodes are identical machines. Client telnet connections to the application cannot be broken because it takes 20 to 30 minutes to recycle the client workstations and transactions will be lost. 
What configuration best provides continuous connectivity to the application?()

B .  IPAT using IP Aliasing and hardware MAC address takeover.
C .  None because continuous telnet connectivity cannot be provided with HACMP.
D .  Shared service IP address assigned to multiple network interface cards on each node.
