Due to recent changes in infrastructure， a four-node cluster has been split into two locations， but is still listed as a single site in HACMP. The location split has proceeded smoothly， the only exception being the serial heartbeats. There are constant errors causing the serial network to go up and down. What is the best solution to resolve this issue？（）
A
Install the dialback failsafe optional filesets.
B
Change the speed parameter in smitty tty to be 38400，8，N，1.
C
Install additional rsct filesets required for non null modem connections.
D

During Company.com planning session， the LVM requirements for HACMP are provided. The administrator explains that there are five volume groups in the current production environment because filesystems constantly change due to the nature of the business. Maintenance outages are limited to one Saturday per month. There is some concern about the amount of time that will be required for outages once HACMP is installed. With HACMP，what will be the simplest methods of managing LVM changes while minimizing required downtime.（） A、 Make changes and allows Lazy Update to sync the changes later.B、 Use the Cluster Single Point Of Control to manage LVM changes.C、 Use exportvg on the primary node and improtvg on the second node.D、 Set up a local NFS cross-mount， and use the local filesystem until the outage.

Which of the following actions will roll back the changes with the least disruption？（）A、Perform a synchronization from a node without the changes.B、Apply the cluster snapshot on both nodes while the cluster is running.C、"Restore HACMP Configuration Database from Active Configuration" on the node where the changes weremadeD、Stop the cluster using the option "Unmanage Resource Groups" and apply the cluster snapshot on thenode where the changes were made

考题
You are the network administrator for your company. The network consists of a single Active Directory domain. All computers on the network are members of the domain. You administer a three-node Network Load Balancing cluster. Each cluster node runs Windows Server 2003 and has a single network adapter. The cluster has converged successfully. You notice that the nodes in the cluster run at almost full capacity most of the time. You want to add a fourth node to the cluster. You enable and configure Network Load Balancing on the fourth node. However， the cluster does not converge to a four-node cluster. In the System log on the existing three nodes， you find the exact same TCP/IP error event. The event has the following description： "The system detected an address conflict for IP address 10.50.8.70 with the system having network hardware address 02：BF://0A：32：08：46." In the System log on the new fourth node， you find a similar TCP/error event with the following description： "The system detected an address conflict for IP address 10.50.8.70 with the system having network hardware address 03：BF://0A：32：08：46." Only the hardware address is different in the two descriptions. You verify that IP address 10.50.8.70 is configured as the cluster IP address on all four nodes. You want to configure a four-node Network Load Balancing cluster. What should you do？ （）A、 Configure the fourth node to use multicast mode.B、 Remove 10.50.8.70 from the Network Connections Properties of the fourth node.C、 On the fourth node， run the nlb.exe resume command.D、 On the fourth node， run the wlbs.exe reload command.
