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？ （）
单项选择题 You are a network administrator for your company. The network contains a Windows Server 2003 computer named Server1. Server1 has a single CPU， 512 MB of RAM， and a single 100-Mb network adapter. All network users’ home folders are stored on Server1. Users access their home folders by using a mapped network drive that connects to a shared folder on Server1. After several weeks， users report that accessing home folders on Server1 is extremely slow at certain times during the day. You need to identify the resource bottleneck that is causing the poor performance. What should you do？ （）
