A two-node cluster provides NFS exports to a variety of UNIX clients. During fallover testing，it is determined that some clients are unable to mount the exported filesystems after fallover，and before node reintegration. It is verified that the filesystems belong to a resource group and are correct in /usr/es/sbin/cluster/etc/exports. Which of the following may provide a possible solution to this problem？（） A、 Use HWAT for IPAT to provide more reliable NFS serving.B、 Use AIX Fast Connect to provide more robust NFS serving.C、 Use NFS Cross Mounting to allow both nodes to export NFS properly.D、 Use the "Filesystem Mounted before IP Configured" flag to provide more predictable NFS serving.

What condition of IPAT via IP aliasing must be taken into consideration？（）A、 The clients must support gratuitous ARP.B、 The network type must support gratuitous ARP.C、 Additional TCP/IP interfaces must be allocated for backup in case of failure.D、 Using IPAT via IP aliasing will reduce the number of rotating resource groups that can be used.
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 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 nodeB、 A single adapter network using persistent addresses on the Network Interface Card in each nodeC、 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
