A Cluster Administrator is implementing a custom resource group for a new web application. The  goal is to ensure the resource group is always active. Preference should be given to the priority node at startup time，but fallback to the priority node should be scheduled during a nonbusy time. 
Using custom resource group options， what combination best achieve the desired resource group behavior？（）

单项选择题An administrator is reviewing the  tmp hacmp.out after an unsuccessful fallover and notice that  the event stop_server PROD_DB failed.  Besides manually intervening，what step must be performed to return the cluster to a stable state？（）

A. Recover From HACMP Script Failure.
B. Release Locks Set By Dynamic Reconfiguration.

D. Restore HACMP configuration Database From Active Configuration.

单项选择题Company.com has non-IBM fibre attached storage. The storage is connected to a node in the  cluster that has multiple adapters and virtual paths. There is a concern about detecting the loss of one of the fibre adapters since there is no indication to the administrator that one has failed.  What feature of HACMP can be sued to assist with this issue？（）

A. Disk heartbeat
B. Error notification
C. Event notification
D. Application monitor

单项选择题Company.com has a non-IBM disk storage unit connected by two Fibre channel connections. The  Nodes have multiple connections to the storage device that allow load balancing. A failure with one Fibre adapter or connection will not be noticed by the application， but it needs to be addressed.  How can HACMP help make this environment more robust？（）

A. Customize disk heartbeat methods to detect disk adapter failures.
B. Customize an error notification method that monitors for volume group quorum loss.
C. Customize an error notification facility to act on the event when reported to the error log.
D. Customize a HACMP event script to monitor the disk connections and cause a fallover if there is a failure.

单项选择题The customer has implemented an SNMPP based network monitoring tool and wishes to monitor chang3es in the cluster. The general status of the cluster is gathered via SNMP but the poling time to retrieve the status is too slow for immediate reaction to serious issues. There is a technical reason why the polling time cannot be changed.  How can HACMP report changes in its status on a more timely basis？（）

A. Create a pre/post event script to report errors more rapidly.
B. Edit SNMP configuration file to send traps for cluster state changes.
C. Change the option in "SRC" to enable trap mode for the "clinfo" process.
D. Use the "monitor" pre-event facility in HACMP to send information to the monitoring device.
