题目
单选题
An HACMP cluster has three nodes of unequal size. The largest node is Node ’A’. The primary application on Node ’A’ has two components. One component is memory intensive, the other is IO intensive. Nodes ’B’ and ’C’ are running web servers and databases that access information produced by applications on Node ’A’. The customer requires the most performance from the primary application and wants all nodes available for fallover processing.  Which of the following is the best solution for meeting the customer requirements?()
A

 Use nodes of equal size.

B

 Create multiple resource groups and use loadlever.

C

 Use dynamic node priority to manage resource groups.

D

 Use an ordered list to manage resource group fallover.
