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？  （）

单项选择题 You are a network adminstrator for your company. You install an intranet application on three Windows Server 2003 computers. You configure the servers as a Network Load Balancing cluster. You configure each server with two network adapters. One network adapter provides client computers access to the servers. The second network adapter is for cluster communications. Cluster communications is on a separate network segment.   The network team wants to reduce the cluster’s vulnerability to attack. These servers need to be highly available. The network team decides that the Network Load Balancing cluster needs to filter IP ports. The team wants the cluster to allow only the ports that are required for the intranet application.   You need to implement filtering so that only the intranet application ports are available on the cluster. You need to achieve this goal by using the minimum amount of administrative effort.   What should you do？  （）
