質問 1：
An administrator is concerned about disk I/O and the impact this may have on a PowerHA cluster. The cluster nodes have virtual disks presented from dual VIO Servers.
What action will improve PowerHA behavior during large disk writes?
A. Tune syncd to 60 seconds
B. Tune I/O pacing with an initial high water mark of 33 and low of 24
C. Tune hcheck_interval to 60 on all cluster node shared volumes
D. Tune cluster node disks qdepth to 16
正解：B
質問 2：

質問 4：
Failure to plan for which element will have a negative impact on PowerHA cluster availability, when using virtual I/O resources on the cluster nodes?
A. Planning for Etherchannel capable switches
B. Planning for at least 2 virtual Ethernet adapters for each cluster network and each node
