IBM High Availability for AIX - Technical Support and Administration -v2 Sample Questions:
Question #1
With encrypted filesystem configuration in a cluster, where can the keystore be located?
A. NFS server
B. LDAP server
C. Each cluster node
D. Repository disk
Question #2
A cluster consists of 2 base boot addresses per node. Each boot address can contact the other node in the cluster but is not externally routable. There is one service IP address in cluster which is externally routable.
The external network experienced a problem where the service IP could not be contacted by the users, but the base boot addresses were still able to send heartbeat packets between the cluster nodes. The resource groups did not failover to the other node where there was no network problem.
How can the administrator ensure that the resource groups failover when the service address is not contactable on a node?
A. Configure a persistent IP address on each node.
B. Create a custom application monitor.
C. Create a process application monitor.
D. Configure a post-event script to the fail_interface event.
Question #3
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. Use the HMC to halt one of the VIO Servers which supports the primary MPIO path
B. On both VIO Servers .remove all rootvg disk mappings for one node.
C. Perform a quick system shutdown using the halt -q command on one node.
D. Delete the rootvg disk devices using the rmdev command.
Question #4
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. Remove the device files for rmt1 on Node1.
B. Redefine the logical device name rmt0 as rmt1 on Node2.
C. Add tape rmt0 on Node1 and assign control to the cluster.
D. Assign a device alias of rmt1 to the device on Node2.
Question #5
What must be done before defining a pre-event command for a predefined cluster event?
A. Specify the absolute path to the command on the "Change/Show Pre-defined PowerHA Event" SMIT dialog
B. Populate the cluster events directory on each node with the script/executable
C. Define a custom event command using the SMIT "Add a Custom Event" dialog
D. Populate the PRE_EVENT_CMD variable in the predefined event script
