#31. You are the administrator of your company's network. You configure a Windows 2000 Server computer as the DNS server for your network. You create both standard primary forward lookup and reverse lookup zones. You discover that when you use the nslookup utility, you cannot resolve host names from IP addresses on your network. You also discover that when you run the Tracert.exe utility, you receive the following error message. "Unable to resolve target system name"
What should you do?

#32. You are the administrator of a Windows 2000 network. The network consists of 30 Windows 2000 Professional computers and two Windows 2000 Server computers named Athens and Boston. Athens has a permanent cable modem connection to the Internet. All Windows 2000 Professional computers on the network are configured to use Automatic Private IP Addressing (APIPA). The network does not contain a DHCP server. To allow all Windows 2000 Professional computers on the network to access the Internet through the cable modem connection of Athens, you install and configure the Network Address Translation (NAT) routing protocol on Athens. You decide to use IP addresses in the range of 192.168.40.1 through 192.168.40.50 for the network. Athens is configured to use an IP address of 192.168.40.1. Boston is a Web server configured with an IP address of 192.168.40.2 and a default gateway of 192.168.40 1. Your Internet service provider (ISP) has allocated two IP addresses, 207.46.179.16 and 207.46.179.17 to your network. The network is shown in the exhibit (Click the Exhibit button). You want to allow Internet users from outside your internal network to use an IP address of 207.46.179.17 to access the resources on Boston through the NAT service on Athens.
How should you configure the network to accomplish this goal?

#33. You are the administrator of a Windows 2000 network. The network consists of two Windows 2000 Server computers named ServerA and ServerB and 180 Windows 2000 Professional computers on one segment. ServerA has an IP address of 192.168.2.1. ServerA is a DHCP server. The TCP/IP configuration of all the Windows 2000 Professional computers is provided by the DHCP server. The range of IP addresses used at ServerA is 192.168.20/24. The lease time used is 15 days. You want to change the IP addresses on the network from 192.168.20/24 to 10.178.0/24. ServerB has an IP address of 10.178.1. You install another DHCP server on ServerB. The range of IP addresses used at ServerB is 10.178.0/24 The lease time used is 15 days. The network is shown in the exhibit (Click the Exhibit button). To ensure compatibility, the two address ranges will be used concurrently on the same segment for three months. Routing between the two address ranges is provided by a router on the network After you activate the DHCP scope on ServerB, users report that they are unable to obtain a valid IP address. When you investigate the problem, you discover that each of the two DHCP servers responds with DHCP negative acknowledge (DHCPNAK) messages to leases requested by the client computers.
What should you do?

#34. You are the administrator of your company's network. The network consists of five subnets that are connected by a BOOTP relay-enabled router. There are 50 Windows 2000 Server computers and 1,000 Windows 2000 Professional client computers distributed approximately evenly across the five subnets. There are also 25 UNIX servers and 100 DHCP-enabled network printers on the network.
You want to accomplish the following goals: The correct assignment of IP addresses to each client computer on each subnet will be automated. Address conflicts between client computers and servers will be prevented. Correct scope options will be applied to each client computer on each subnet. Client computers that are not in use will be prevented from keeping an IP address for more than three days. Each network printer will always receive the same IP address.
You take the following actions: Install the DHCP Server service on a Windows 2000 Server computer. Create five scopes, each containing the address range for a specific subnet. In the DHCP console, set optional client configurations for each scope in the Scope Options container. Exclude the range of addresses in use by the servers. Exclude the range of addresses in use by the network printers.
Which result or results do these actions produce? (choose all that apply)

#35. You are the administrator of your company's network. The network consists of 10 Windows 2000 Server computers, 100 Windows 2000 Professional computers, and 150 Windows NT Workstation computers. For workgroup collaboration and document sharing, all client computers have file and print sharing services enabled. You are using DHCP to automate the TCP/IP configuration of all client computers.
You want to accomplish the following goals: All client computers will be able to be located on the network by the network's fully qualified domain name. A (host) records for all client computers will be automatically added to the DNS zone files. PTR (pointer) records for reverse name lookup for all client computers will be automatically added to the DNS zone files A records and PTR records will be automatically removed from the DNS zone files when the DHCP lease expires.
You take the following actions: Configure the DHCP server to never update client information in DNS. Configure the DHCP server to discard forward lookups when the lease expires. Configure the DHCP scope to configure the domain name for all DHCP client computers.

#36. You are the administrator of your company's network. The network consists of one Windows 2000 domain that has 10 Windows 2000 Server computers and 500 Windows 2000 Professional client computers. You want all client computers to receive their TCP/IP configuration from DHCP. You install the DHCP Server service on one of your Windows 2000 Server computers and create and activate a scope of addresses. Users report that they cannot connect to the network. You discover that none of the client computers are receiving TCP/IP configurations from DHCP.
What should you do to resolve this problem?

#37. You are the administrator of a Windows 2000 domain named contoso.com. The domain has a Windows 2000 member server computer named Ras1 and a Windows 2000-based DHCP Server computer named Dora. Routing and Remote Access is enabled for remote access on Ras1. The network has two DNS servers that use IP addresses of 10.152 and 10.153. Ras1 is configured to use DHCP to assign IP addresses to the remote access client computers. The configuration of the scope options on the DHCP server is shown in the following window. DHCP ~1~ dora,contoso.com[10.1.5,1] 8J1t1 Scope [10.1.5.0] Net5 ji1i) Address Pool f;o Address Leases ff]1J8 Reservations -11..1 !~ Server Options r~;";::)\"!f""""'!"'W;: "W e006 DNS Servers Standard 10.1.5.3 None
The DHCP scope does not have any client computer reservations When remote access client computers dial in to Ras1, they receive an IP address from the DHCP scope range, but they do not receive the DNS address configured in the DHCP scope. Instead, the remote access client computers receive a DNS server address of 10.1. 52 You want the remote access client computers to receive the DNS option from the DHCP server
How should you configure the network to accomplish this goal?

#38. Your company has four branch offices Atlanta, Boston, New York and Dallas. There is a multicast address used for videoconferences and the like to deliver content to all four sites. Atlanta and Boston are right beside each other connected by a router. There is a Sales videoconference held every Monday between Atlanta and Boston.
How should you configure the router so that the Sales multicast videoconferencing does not get broadcasted to all four branches?
