IBM High Availability for AIX - Technical Support and Administration -v2 Sample Questions:

1. An architect is designing a PowerHA cluster and plans to use a virtualized environment to maximize hardware utilization. Each cluster node is to be configured as a partition on a separate Power 770.
Which of the following options provides a supported configuration with the minimum single points of failure?

A) Implement a single IVM partition on each Power system. Configure paths to physical storage active / passive mode on each cluster node with one path using a physical adapter and one path using a virtual adapter.
B) Implement dual IVM partitions on each Power system. Each IVM partition will have multiple paths to the physical storage.
C) Implement dual VIO Servers on each Power system. Each VIO Server will have multiple paths to the physical storage.
D) Implement a single VIO server on each Power system. Configure paths to physical storage in active / passive mode on each cluster node with one path using a physical adapter and one path using a virtual adapter.

2. A PowerHA 6 cluster uses IPAT with aliasing and disk heartbeat. The administrator noticed the standby node crashes during a failover test. There are entries related to the Dead Man Switch (DMS) timeout in the AIX error log.
Which action is recommended to reduce the risk of DMS timeouts?

A) Set Failure detection rate of Ethernet to normal.
B) Create a RS232 heartbeat and set failure detection rate to delay.
C) Dedicate a set of disks for disk heartbeat and set failure detection rate to delay.
D) Set Failure detection rate of diskhb network module to slow.

3. An administrator created a new volume group on one local node using the mkvg command. The volume group is not known on the other nodes in the cluster, however the disks are available and have PVIDs defined.
How can this volume group be added into an online resource group, and the volume group information get updated on the remote node(s), with the least amount of effort?

A) Set: Use forced varyon for volume groups, if necessary, to "true."
B) Allow the daily automatic cluster verification to auto-correct the volume group definition
C) Synchronize the cluster using the auto-correct verification errors set to "yes."
D) Change the resource group option: Automatically Import Volume to "true."

4. When verifying a cluster, where will the clverify.log file be stored?

A) On all cluster nodes
B) On the cluster node where the operation was initiated
C) On each cluster node with an active resource group
D) On the cluster topology manager node

5. An administrator wants to change the nodename of one node while a PowerHA 6 cluster is running. Which actions will achieve this?

A) Change name of node.
Verify and synchronize cluster.
B) Change the hostname in AIX
Update /etc/hosts with the new name of the node
Use C-SPOC "Update HACMP Communication Interface with AIX Settings".
C) Stop cluster services on the node.
Change the name of the node.
Verify and synchronize cluster.
Start cluster services.
D) Move all resource groups from the node to be changed.
Change the name of node.
Move resource groups to the hosts with the new name.
