[单选]
An HACMP cluster is planned for two logical partitions on IBM p690 servers. Both partitions have three network interface adapters： two service adapters on a production network connected to an IP switch， and an administration adapter on a stand-alone hub that is connected to the p690 server’s HMC. Non-IP hearbeat paths cannot be configured due to the available hardware in the p690 servers.
Given the resources available，what is the best configuration for this cluster？（）

A . Add hardware to provide either serial heartbeats or shared disk heartbeats.
B . Define the administration network so HACMP will send heartb4eats over the non-routed network.
C . Add the administration network adapters to the production resource groups with IPAT via IP replacement selections.
D . Configure the IP Network Interface Module in HACMP with an increased heartbeat detection rate to prevent node isolation confutations.
