第9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 Network Load Balancing cluster that consists of three nodes. Each node runs Windows Server 2003 and contains a single network adapter. The Network Load Balancing cluster can run only in unicast mode. The Network Load Balancing cluster has converged successfully.   To increase the utilization of the cluster， you decide to move a particular application to each node of the cluster. For this application to run， you must add a Network Load Balancing port rule to the nodes of the cluster.   You start Network Load Balancing Manager on the second node of the cluster. However， Network Load Balancing Manager displays a message that it cannot communicate with the other two nodes of the cluster.  You want to add the port rule to the nodes of the cluster.   What should you do？  （）

• A、 Use Network Load Balancing Manager on the Network Load Balancing default host to add the port rule.
• B、 Change the host priority of the second node to be the highest in the cluster， and then use Network Load Balancing Manager to add the port rule.
