An administrator has a 4-node PowerHA cluster which was successfully verified and synchronized
on Sunday.
On Wednesday the cluster was changed by a different administrator.

The cluster must be returned to the Sunday configuration and resynchronized.
How would an administrator restore the cluster to the original configuration when the changes
made on Wednesday are not known?

A PowerHA 7 cluster is running on two fully virtualized LPARs. An administrator simulates a
network failure on the cluster by running the “ifconfig enX down” command on all network
interfaces on one node. The resource group moved, and clstat shows the cluster as stable on both
nodes.
What prevented the resource group from being active on both nodes?

In which default file can an administrator specify special options for nfs exported filesystems in
PowerHA?

What step can be taken after installing PowerHA, and before creating a cluster, to ensure that
unauthorized communication between systems using clcomd is prevented?

The addition of a service IP address to a resource group fails to pass verification and
synchronization.
What is the most likely reason?

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?

In PowerHA 7 cluster, how many multicast IP addresses are required?

The service IPs VLAN is the only routable network in a 2-node HA cluster with multiple network
interfaces.
What must done to enable administrative tasks to be performed remotely on the cluster nodes?

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?

In multi-node disk heartbeat configurations running PowerHA 6, what is the recommended
minimum number of LUNS to be shared between the nodes?
