While adding the forced varyon volume group option， it is decided to create a disk heartbeat Network over the disk paths. Which HACMP function is used to create disk heartbeat devices？（）

A. The Disk hearbeat facility is initialized when creating enhanced concurrent mode volume groups through HACMP.
B. HACMP does not create the disk heartbeat area directly； RSCT facility creates the area used for the disk heartbeat when the device is started by Group Services.
C. The ’Chdev -v-C " command creates an enhanced Volume Group from an ordinarilyVolume Group. This creates the heartbeat region on the vfirst disk in the chain.
D. The disk heartbeat area on the disk is created and initialized when the device is created inHACMP "Extended Configuration -> Extended Topology -> Disk heartbeat facility" smit path.

A. The clients must support gratuitous ARP.
B. The network type must support gratuitous ARP.
C. Additional TCP/IP interfaces must be allocated for backup in case of failure.
D. Using IPAT via IP aliasing will reduce the number of rotating resource groups that can be used.

单项选择题Company.com has a four-node cluster （nodes ’A’， ’B’， ’C’， and ’D’）. The nodes are set up in Resource group pairs. Node ’A’ falls over to Node ’B’， and Node ’C’ falls over to Node ’C’. During a maintenance windows， it was discovered that the six resource groups on Node ’A’ are too much to be adequately handled by Node ’B’. What could be done to better utilize the available resources during fallover？（）

A. Implement Work Load manager so that the application monitors for additional resource requirements.
B. Add a fifth node to function as a load leveler in order to control the dispatching of the resource jobs.
C. Implement Dynamic Node Priorities in the resource groups in order to find a node with suitable system resources.
D. Reduce the number of resource groups on Node ’A’ to 1 in order to ensure faster and more robust fallover to a single system.

单项选择题A two-node cluster has both a single TCP IP heartbeat and a single non-IP serial heartbeat. TheService Level Agreement regarding the speed of cluster fallover has been updated，and Fast Disk Takeover will be implemented to meet the new Service Level Agreement. Which of the following should be implemented to increase the reliability of Fast Disk Takeover？（）

A. Disk should be mirrored across separate storage enclosures.
B. Disk heartbeats should be added over multiple disk adapters.
C. Disk major and minor numbers should be set as unique across nodes.
D. Disk adapter queue_depth should be increased from the default values.
