单项选择题

An administrator is configuring a PowerHA cluster consisting of two nodes across two physical Power systems，570-1 and 570-2.
Node1 is an LPAR on 570-1Node2 is an LPAR on 570-2.
Dev1 is an LPAR on 570-2 （this LPAR is not part of the cluster）.
The cluster will manage a single resource group， RG1， with a single application server， APP1. The resourcegroup will have a home node of Node1.
Node1 is configured with 4.0 CPU desired， 0.4 minimum， 4.0 maximum， and 4 virtual processorsNode2 isconfigured with 0.4 CPU desired， 0.4 minimum， 4.0 maximum， and 4 virtual processors Dev1 is configuredwith 4.0 CPU desired， 0.4 minimum， 4.0 maximum， and 4 virtual processors
When the resource group RG1 is acquired by Node2 the administrator would like to dynamically move 3.6processor entitlement units from Dev1 to Node2. How could the administrator achieve this in the PowerHAcluster？（）

A.Create a custom event script to perform the change to CPU entitlement
B.Modify the extended performance tuning parameters for the cluster to modify CPU entitlement uponresource group acquisition
C.Customize the resource group attributes of RG1 so that the CPU entitlement is modified for Node2 uponresource group acquisition
D.Customize the application server attributes of APP1 so that the CPU entitlement is modified for Node2upon resource group acquisition

A.Emulate the errpt entry from the HACMP Error Notification menu
B.Execute a custom test procedure from the HACMP Cluster Test Tool menu
C.Emulate the LVM_SA_QUORCLOSE event from the HACMP Event Emulation menu
