An operator just completed a repair to a disk subsystem that contains a disk heartbeat. Before returning the system back into production mode， there is a requirement to verify the disk heartbeat is functioning. 
How should the operator determine if the disk heartbeat network functioning？（）

单项选择题A three-node cluster experienced a node failure. The resource groups were acquired as cexpected. The node has been repaired，and HACMP has been restarted.  How does the operator determine that the node has successfully re-integrated into the cluster？（）

A. Use the clstat command.
B. Use the cIRGinfor command.
C. Tail the /etc/hacmp.out file and wait for "node_up_complete" to finish successfully.
D. Tail the /usr/es/adm/cluster.log file and wait for "node_up_complete" to finish successfully.

单项选择题A cluster administrator has been asked to install HACMP on two nodes with the following  hardware：   -two CPUs， - 1GB RAM， - one 1 36GB drive， -two 10 100 1000 Ethernet adapters， and -GB Fibre Channel adapters dual attached to SAN storage.  In order to eliminate single points of failure，the administrator should first add which of the following：（）

A. an additional 1GB RAM to each node.
B. Another bootable mirrored disk drive.
C. A 10/100/1000 GB Ethernet adapter to be attached to a redundant switch.
D. Nothing，because this is a viable cluster solution with no single points of failure.
