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 three-node Network Load Balancing cluster. Each cluster node runs Windows Server 2003 and has a single network adapter. The cluster has converged successfully. You notice that the nodes in the cluster run at almost full capacity most of the time. You want to add a fourth node to the cluster. You enable and configure Network Load Balancing on the fourth node. However, the cluster does not converge to a four-node cluster. In the System log on the existing three nodes, you find the exact same TCP/IP error event. The event has the following description: "The system detected an address conflict for IP address 10.50.8.70 with the system having network hardware address 02:BF://0A:32:08:46." In the System log on the new fourth node, you find a similar TCP/error event with the following description: "The system detected an address conflict for IP address 10.50.8.70 with the system having network hardware address 03:BF://0A:32:08:46." Only the hardware address is different in the two descriptions. You verify that IP address 10.50.8.70 is configured as the cluster IP address on all four nodes.

单选题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.
