IBM Assessment: High Availability for AIX - Technical Support and Administration -v2 Sample Questions:
Question #1
A shared volume group is added to a resource group and verification of the change produces an error. What is the most likely reason?
A. The volume group major number is different on some nodes in the cluster.
B. The auto vary on flag is set to "yes".
C. The volume group is varied off on all of the nodes.
D. The names of one or more disks in the volume group do not match on all the nodes in the resource group.
Question #2
What is the command used to check the status of all interfaces and hearbeats in a PowerHA 7 cluster?
A. Iscluster-i
B. cllsif-p
C. cltopinfo-m
D. Issrc-Is topsvcs
Question #3
An administrator wants to run the cluster test tool automated procedure. Part of this will perform a test to kill the clstrmgrES subsystem on a node, causing that node to halt.
How can the administrator avoid manual intervention to restart the node?
A. Run the cl_testtool_auto command with the option "-K n" to specify that the clstrmgrES subsystem should not be killed
B. Set the environment variable "CL_KILL_CLSTRMGR=FALSE" and make sure clexit.rc is executable before running the test
C. Edit the file /usr/es/sbin/cluster/cl_testtool_auto_cluster_kill" replace the action CLSTRMGR_KILL with CLSTRMGR_SOFT_KILL
D. Modify and make executable /etc/cluster/hacmp.term" to change the action taken by the system upon an abnormal termination of clstrmgrES
Question #4
An administrator plans to migrate a PowerHA 6 cluster with AIX 7 nodes to PowerHA 7. Which migration method should be used to minimize downtime?
A. Non-disruptive migration
B. Snapshot migration
C. Offline migration
D. Rolling migration
Question #5
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.
