A. Mirror the LVs and set each logical partition copy on separate physical volume to superstrict.
B. Mirror the VG and set inter-physical volume allocation policy to yes.
C. Mirror hdisk3 and set logical partition on separate physical volume policy to maximum.
D. Mirror the/db2 and set each logical partition copy on separate physical volume to strict.
正解：A

質問 3：
An administrator tries to replace a hot-plug Ethernet adapter using the C-CPOC > Communication Interfaces SMIT menu. When prompted, the administrator selects the incorrect adapter and does not wish to continue. When prompted to confirm adapter replacement, he selects "no".
What is the first action that the administrator must take to restore cluster to the pre-maintenance condition?
A. Run the drslot command to take the PCI slot out of the "removed" state.
B. Migrate the resource groups using the adapter back to the node.
C. Run Cluster Verification and Synchronization to reset the adapter state.
D. Run the cfgmgr command to re-detect the adapter and create the device special files
正解：A

質問 4：
A PowerHA 6 cluster has missed too many heartbeats during a large disk write operation, and has triggered the deadman switch. Which tunable can help ensure that HA Cluster Manager continues to run?
A. Asynchronous I/O and disk queue_depth
B. Syncd frequency and asynchronous I/O
C. I/O Pacing and asynchronous I/O
D. I/O Pacing and syncd frequency
正解：D

質問 5：
An administrator is planning a PowerHA implementation for a database and application. The application is dependent on the database being available before the application is started.
If the database is moved from one node to another, the application will need to be re-started. The database and application will be in different resource groups.
How can this be achieved within PowerHA?
A. The application resource group can be configured as the parent of the database resource group.
B. The application resource group can be configured as a child of the database resource group.
C. A sequential processing order for the resource groups can be set, specifying the database and then the application
D. The application can be controlled from a post event to the rg_move_finish event.
正解：B

質問 6：
Consider the following Cluster Service Settings:

An administrator changes cluster configurations and starts one node in the cluster. The node being started fails. What is the root cause of the failure?
A. The administrator did not synchronize the cluster.
B. Cluster synchronization failed during startup cluster verification.
C. PowerHA detected errors during startup cluster verification.
D. PowerHA failed to correct errors during startup cluster synchronization.
正解：A

質問 7：
An administrator wants to assign a tape drive to a resource group for ease of management and control.
The tape drive is already attached to two cluster nodes. Node1 and Node2.
On Node1, the tape drive has a logical device name of rmt1. Node1 also has a tape drive, rmt0, that is not controlled by the cluster.
On Node2 the tape drive has a logical device name of rmt0.
Which of the following must the administrator do before adding the tape drives to the cluster resource group?
A. Redefine the logical device name rmt0 as rmt1 on Node2.
B. Assign a device alias of rmt1 to the device on Node2.
C. Add tape rmt0 on Node1 and assign control to the cluster.
D. Remove the device files for rmt1 on Node1.
正解：A
