单项选择题 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.

单项选择题 You are a network administrator for your company. The network contains four Windows Server 2003 computers configured as a four-node server cluster. Each cluster node is the preferred owner of a clustered instance of Microsoft SQL Server 2000， and each cluster node is configured as a possible owner of all other instances of SQL Server. All nodes have identically configured hardware. All four nodes operate at a sustained 70 percent CPU average. You add a server that has identically configured hardware to the cluster as a fifth node. You want each SQL Server instance to continue operating at the same level of performance in the event of a single node failure. What should you do？ （）
单项选择题 You are a network administrator for your company. You install Windows Server 2003 on two servers named Server1 and Server2. You configure Server1 and Server2 as a two-node cluster. You configure a custom application on the cluster by using the Generic Application resource， and you put all resources in the Application group. You test the cluster and verify that it fails over properly and that you can move the Applications group from one node to the other and back again. The application and the cluster run successfully for several weeks. Users then report that they cannot access the application. You investigate and discover that Server1 and Server2 are running but the Application group is in a failed state. You restart the Cluster service and attempt to bring the Application group online on Server1. The Application group fails. You discover that Server1 fails， restarts automatically， and fails again soon after restarting. Server1 continues to fail and restart until the Application group reports that it is in a failed state and stops attempting to bring itself back online. You need to configure the Application group to remain on Server2 while you research the problem on Server1. What should you do？ （）
