单选题 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?()   

A

 Use the clinfo command to monitor the disk heartbeat

B

 Use the mail command to check for messages form HACMP

C

 Use the dhbread command to verify the disk heartbeat link

D

 Use the clstat command to verify the appropriate network connections are available

单选题 To perform SNMP Monitoring of cluster, what daemon must be running?()  

A

 /usr/sbin/rsct/bin/hagsd

B

 /usr/sbin/rsct/bin/clinfo

C

 /usr/sbin/rsct/bin/clsmuxpd

D

 /usr/sbin/rsct/bin/clssnmpstatd

单选题 Company.com wishes to use HACMP on two IBM eServer pSeries servers. During the planning  session, it was decided to use the native serial ports s1 or s2 for a non-IP heartbeat network.  What should be done to ensure the serial network will function with HACMP heartbeats?()  

A

 Use either s1 or s2 port configured as a TTY interface with a NULL Modem cable.

B

 Use the s2 serial port on each system configured as a TTY interface with a NULL modem cable.

C

 Use the s1 port on each system configured as a TTY interface with a standard serial modemcable.

D

 Verify with IBM support which native serial ports for the server model can be used for HACM  pheartbeats.

单选题 During a planning session, Company.com expresses concern about the behavior of the nodes  When HACMP is installed. Once department is reliant on an older piece of equipment that is critical to operations and must communicate to the database server. Previous network changes indicated that this piece of equipment does not support gratuitous ARP.  How can HACMP best incorporate this restriction into the cluster design?()  

A

 The administrator must use Hardware Address Take over with HACMP.

B

 The clsmuxpd process and the contents of the /etc/cluster/ping_client_list can address the issue.

C

 HACMP does not have any facility to be compatible with older devices that have limited capabilities.

D

 HACMP can use either hardware address take over,or clinfo can update the arp cache of the clients when an adapter event occurs.

单选题 A cluster administrator is trying to configure tmssa for the non-IP network. Having installed the devices.ssa.tm.rte fileset, what is the next step that must be performed to create the target mode devices?()  

A

 Reboot each cluster node.

B

 Change the ssa node number to a non-zero value.

C

 Change the SSAR device state from defined to available.

D

 Run the cfgmgr process on each node to create the target mode devices.

单选题 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.

单选题 A cluster script failed because it was unable to set the hostname, and the Cluster Manager reported the event failure. What must be done prior to sue the "HACMP Problem Determination Tools" -> "Recover From Script Failure" to have the Cluster Manager resume cluster processing?()  

A

 Nothing, the Recover From Script Failure will correct the issue.

B

 Disable and re-enable the effected Ethernet adapter by using ifconfig.

C

 Correct the error by setting the hostname on the effected node from the command line.

D

 Verify that the clinfo daemon is running prior to executing the recover from scriptfailure.
