第4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.   What should you do？  （）

• A、 Use Network Load Balancing Manager on the Network Load Balancing default host to add the port rule.
• B、 Change the host priority of the second node to be the highest in the cluster， and then use Network Load Balancing Manager to add the port rule.
• C、 Run the nlb.exe drain command on each node， and then use Network Load Balancing Manager to add the port rule.
• D、 Add the port rule through Network Connections Properties on each node.

You work as the IT professional in an international company which is named Wiikigo. You are experiencedin implementing and administering a network operating system. You are specialized in deploying servers，configuring Windows Server 2008 Terminal services and network application services， and configuring aweb services infrastructure. You work in a company named Wiikigo， Ltd. and there is a two-node Network Load Balancing cluster. Onlythe intranet Web site will be provided with the high availability and load balancing by the cluster. Thecompany names the cluster as web.wiikigo.com. You find a problem that the Network Load Balancingcluster can be seen in the network neighborhood by the Wiikigo users. And the users can utilize the web.wiikigo.com name to get access to various services. The web.wiikigo.com Network Load Balancing clusteris set with only one port rule. Since you are the technical support， you are required have the web.wiikigo.com Network Load Balancing cluster configured to receive only HTTP traffic. Which two actions should be performed to achieve the goal？（）

• A、To achieve the goal， the Network Load Balancing Clusters console should be opened and a new Allow rule should be created for TCP port 80.
• B、To achieve the goal， the Network Load Balancing Clusters console should be opened and the default port rule should be modified to a disabled port range rule.
• C、To achieve the goal， one of the cluster nodes should be logged on to and the wlbs disable all command should be run.
• D、To achieve the goal， the Network Load Balancing Clusters console should be opened and the default port rules should be deleted.
