单选题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？ （）A On Server2， configure the failover threshold to 0.B On Server2， configure the failover period to 0.C Remove Server1 from the Possible owners list.D Remove Server1 from the Preferred owners list.
单选题You are the network administrator for your company. The network contains an application server running Windows Server 2003. Users report that the application server intermittently responds slowly. When the application server is responding slowly， requests that normally take 1 second to complete take more than 30 seconds to complete. You suspect that the slow server response is because of high broadcast traffic on the network. You need to plan how to monitor the application server and to have a message generated when broadcast traffic is high. You also want to minimize the creation of false alarms when nonbroadcast traffic is high. What should you do？ （）A Use the Alerts option in the Performance Logs and Alerts snap-in to configure an alert to trigger when the Datagrams/sec counter in the UDPv4 object is high.B Use System Monitor and configure it to monitor the Segments/sec counter in the TCPv4 object. C Use System Monitor and configure it to monitor the Datagrams/sec counter in the UDPv4 object.D Use the Alerts option in the Performance Logs and Alerts snap-in to configure an alert to trigger when the Datagrams/sec counter in the TCPv4 object is high.
