第4题：

Your company named Contoso， Ltd. has a two-node Network Load Balancing cluster. The cluster is intended to provide high availability and load balancing for only the intranet Web site. The name of the cluster is web.contoso.com.  You discover that Contoso users can see the Network Load Balancing cluster in the network neighborhood and can connect to various services by using the web.contoso.com name. The web.contoso.com Network Load Balancing cluster is configured with only one port rule.  You need to configure the web.contoso.com Network Load Balancing cluster to accept only HTTP traffic. Which two actions should you perform？（）

• A、Log on to one of the cluster nodes and run the wlbs disable all command.
• B、Open the Network Load Balancing Clusters console and delete the default port rules.
• C、Open the Network Load Balancing Clusters console and create a new Allow rule for TCP port 80.
• D、Open the Network Load Balancing Clusters console and change the default port rule to a disabled port range rule.

Your network contains a Web-based application that runs on Windows Server 2003. You plan to  migrate the Web-based application to Windows Server 2008 R2. You need to recommend a server  configuration to support the Web-based application. The server configuration must meet the following  requirements：   èEnsure that the application is available to all users if a single server？fails èSupport the installation of .NET applications èMinimize software costs  What should you recommend？（） 

• A、Install the Server Core installation of Windows Server 2008 R2 Standard on two servers. Configure the servers in a Network Load Balancing cluster.
• B、Install the full installation of Windows Server 2008 R2 Web on two servers. Configure the servers in a Network Load Balancing cluster.
• C、Install the full installation of Windows Server 2008 R2 Enterprise on two servers. Configure the servers in a failover cluster.
• D、Install the full installation of Windows Server 2008 R2 Datacenter on two servers. Configure the servers in a failover cluster.

第9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 plan to deploy two virtual machines （VMs） that will be configured as nodes in a failover cluster. The VMs will run file and print services. You need to recommend a storage solution for the planned deployment. What should you include in the recommendation？（）

• A、pass-through disks
• B、Network Load Balancing （NLB） for the Hyper-V hosts
• C、virtual machine queue （VMQ）
• D、Cluster Shared Volumes （CSV）
• E、an iSCSI Storage Area Network （SAN）
• F、a failover cluster for the Hyper-V hosts
• G、Network Load Balancing （NLB） for the VMs
• H、Network Attached Storage （NAS）
• I、Microsoft System Center Operations Manager with Performance and Resource Optimization （PRO）
• J、Windows System Resource Manager （WSRM）
• K、a failover cluster between the VMs
