单项选择题
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.

Company.com wishes to use HACMP on two IBM eServer pSeries servers. During the planning session， it was decided to use the native serial ports s1 or s2 for a non-IP heartbeat network. What should be done to ensure the serial network will function with HACMP heartbeats？（）
A. Use either s1 or s2 port configured as a TTY interface with a NULL Modem cable.
B. Use the s2 serial port on each system configured as a TTY interface with a NULL modem cable.
C. Use the s1 port on each system configured as a TTY interface with a standard serial modemcable.
D. Verify with IBM support which native serial ports for the server model can be used for HACM pheartbeats. -

The administration staff of a large computer complex is resisting the installation of HACMP. There Are concerns about the difficulty of managing and administering an HACMP cluster without an "administration only" network. Adding adapters to create an administration network is not possible due to limitations on the number of open IO slots in the servers. What can be done to address this issue？（）
A. Create HACMP persistent IP labels for administration purposes.
B. Use HWAT to ensure the correct MAC address is available at all times.
C. Nothing can be done because RPAT is a characteristic of HACMP that cannot be changed.
D. Use IP aliasing within HACMP to allow the administrators constant access to the nodes. -

Company.com has I/O slot constraints on two nodes that are going to be configured in an HACMP cluster. There is room for only one Network Interface Card in each node，in addition to the built-in Ethernet port on the system planer. The best HACMP configuration for these servers is to implement：（）
A. A single adapter network using the Network Interface Card in each node
B. A single adapter network using persistent addresses on the Network Interface Card in each node
C. A dual adapter network using the internal Ethernet adapters as an non-service interface with IPAT via IP Replacement.
D. EtherChannel high availability for the network connections with HACMP cascading resource groups for data and application fallover
