質問 1:An administrator is concerned about disk I/O and the impact this may have on a PowerHA cluster. The cluster nodes have virtual disks presented from dual VIO Servers.
What action will improve PowerHA behavior during large disk writes?
A. Tune hcheck_interval to 60 on all cluster node shared volumes
B. Tune syncd to 60 seconds
C. Tune cluster node disks qdepth to 16
D. Tune I/O pacing with an initial high water mark of 33 and low of 24
正解:D
質問 2:An administrator needs to deploy a newPowerHA 6 cluster with characteristics similar to an existing cluster. A cluster snapshot of the existing cluster is taken and converted using the cl_exportdefinition facility. The On-Line Planning Worksheet (OLPW) tool is used to make changes to the configuration and the resulting OLPWfile is transferred to one of the new cluster nodes.
Which command will restore the new configuration?
A. cljmportdefinition-f[OLPWfile]
B. cl_opsconfig-f[OLPWfile]
C. clconvert_shapshot-f[OLPWfile]
D. clsnapshot-a-n[OLPWfile]
正解:B
質問 3:Given the following output, why is node Jessica down?
A. Failover happened because disk heartbeat network was down on node Jessica.
B. Node Jessica lost access to shared volume groups and releasing resource group has failed.
C. An rj_move event happened and node Peyton has failed to acquire resource group.
D. Selective failover on network loss has happened and resource group was moved to node Peyton.
正解:B

Mar 29 06:09:22 EVENT COMPLETED: network_down -1 net_ether_01 0
Mar 29 06:09:29 EVENT START: network_down_complete -1 net_ether_01
Mar 29 06:09:29 EVENT COMPLETED: network_down_complete -1 net_ether_01 0
A. Non-redundant network switch has failed
B. One interface in net_ether_01 has failed
C. Some heartbeat packets have been lost on one node in a cluster
D. The service IP address was moved to another adapter
正解:A
質問 5:An administrator added a filesystem on a shared volume group using C-SPOC. The cluster is active and the resource group is on line. What is the effect of the administrator action?
A. The filesystem must be mounted on a node with an online resource group.
B. The filesystem is available immediately.
C. Cluster services must be restarted on all nodes.
D. The cluster must be verified and synchronized.
正解:B
質問 6:An administrator is using PowerHA 7 to define a new cluster using SMIT option "Setup a Cluster, Nodes and Networks" and encountered the following error message:
What is the root cause of the problem?
A. The nodes were not defined in the DNS
B. The CAA repository disk is not accessible on all nodes
C. The CAA cluster was not defined before defining the PowerHA Cluster
D. The /etc/cluster/rhosts are not populated correctly
正解:D
質問 7:An administrator has installed and configured AIX and PowerHA 7 on multipath vSCSI disks. There are two VIO Servers, and both are accessing the same SAN storage system. The administrator has modified setting for the rootvg system event in the cluster. The cluster is synchronized and stable.
How can the administrator test the rootvg system event to ensure the change behaves as expected?
A. Delete the rootvg disk devices using the rmdev command.
B. On both VIO Servers .remove all rootvg disk mappings for one node.
C. Use the HMC to halt one of the VIO Servers which supports the primary MPIO path
D. Perform a quick system shutdown using the halt -q command on one node.
正解:B
