You are the network administrator for your company. You need to provide Internet name resolution services for the company. You set up a Windows Server 2003 computer running the DNS Server service to provide this network service.
During testing， you notice the following intermittent problems：
Name resolution queries sometimes take longer than one minute to resolve.
Some valid name resolution queries receive the following error message in the Nslookup command-line tool： "Non-existent domain."
You suspect that there is a problem with name resolution.
You need to review the individual queries that the server handles. You want to configure monitoring on the DNS server to troubleshoot the problem.
What should you do？ （）
A. In the DNS server properties， on the Debug Logging tab， select the Log packets for debugging option.
B. In the DNS server properties， on the Event Logging tab， select the Errors and warnings option.
C. In System Monitor， monitor the Recursive Query Failure counter in the DNS object.
D. In the DNS server properties， on the Monitoring tab， select the monitoring options.

单项选择题
You are the network administrator for your company. The network consists of a single Active Directory domain. The network contains Windows Server 2003 file servers. The network also contains a Windows Server 2003 computer named Server1 that runs Routing and Remote Access and Internet Authentication Service （IAS）. Server1 provides VPN access to the network for users’ home computers. You suspect that an external unauthorized user is attempting to access the network through Server1. You want to log the details of access attempts by VPN users when they attempt to access the network. You want to compare the IP addresses of users’ home computers with the IP addresses used in the access attempts to verify that the users are authorized. You need to configure Server1 to log the details of access attempts by VPN users. What should you do？ （）
A. Configure the system event log to Do not overwrite.
B. In IAS， in Remote Access Logging， enable the Authentication requests setting.
C. Configure the Remote Access server to Log all events.
D. Create a custom remote access policy and configure it for Authentication-Type. -
单项选择题
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 four-node Network Load Balancing cluster. All nodes run Windows Server 2003. The cluster has converged successfully. You use Network Load Balancing Manager on the default host to configure all nodes of the cluster. The nodes have a single network adapter and are connected to the same switching hub device. Administrators of non-cluster servers that are connected to the same switching hub device report that their servers receive traffic that is destined for the cluster nodes. Receiving this additional network traffic impairs the network performance of the non-cluster servers. You need to ensure that traffic destined for only the cluster nodes is not sent to all ports of the switching hub device. You do not want to move the cluster to another switching hub device. What should you do？ （）
A. On one node， run the nlb.exe reload command.
B. On each node， run the wlbs.exe drainstop command.
C. Use Network Load Balancing Manager to enable Internet Group Management Protocol （IGMP） support on the cluster.
D. Use Network Load Balancing Manager to add a second cluster IP address. -

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. You want to configure a four-node Network Load Balancing cluster. What should you do？ （）
A. Configure the fourth node to use multicast mode.
B. Remove 10.50.8.70 from the Network Connections Properties of the fourth node.
C. On the fourth node， run the nlb.exe resume command.
D. On the fourth node， run the wlbs.exe reload command.
