Network address Translation key points

1. 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 config.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 192168.40.1 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?

A. Configure Athens with a static route on the private interface of the NAT routing protocol.
Use a destination address of 207.46.179.17, a network mask of 255.255.255.255, and a gateway of 192.168.40.2
B. Configure Boston with a static route on the U\.N interface. Use a destination address of 192.168.40.1, a network mask of 255.255.255.255, and a gateway of 207.46.179.17
C. Configure the U\.N interface of Boston to use multiple IP addresses Assign the additional lP address of 207.46.179.17 to the interface.
D. Configure the public interface of the NAT routing protocol to use an address pool with a starting address of 207.46.179.16 and a mask of 255.255.255.254. Reserve a public IP address of 207.46.179.17 for the private IP address of 192.168.40.2

Answer:D

2. To allow Internet access through a dial-up connection to Server A, you install NAT routing protocol. All computers in your network use Automatic Private IP addressing. There is no DHCP server in the network. Server A is configured as below:

LAN interface has an IP address of 10.65.3.1 and a subnet mask of 255.255.255.0.
NAT automatically assigns IP addresses of 10.65.3.2 through 10.65.3.60 to computers on the private interface.
NAT uses a demand-dial interface named Dial ISP to connect to the ISP.
The demand-dial interface uses an address pool of 207.46.179.33 through 207.46.179.36.
The routing table has a default static route for the public interface.

What configuration should you use for the static route for the public interface?

A. Interface: Local Network Connection
Destination: 207.46.179.44
Network Mask: 255.255.255.255
Gateway: 0.0.0.0

B. Interface: Local Network Connection
Destination: 10.65.3.0
Network Mask: 255.255.255.0
Gateway: 10.65.3.1

C. Interface: Dial ISP
Destination: 0.0.0.0
Network Mask: 0.0.0.0
Gateway: None

D. Interface: Local Network Connection
Destination: 207.46.174.32
Network Mask: 255.255.255.240
Gateway: 207.46.179.32

Answer:C

3. You are the administrator of a Windows 2000 network. The network consists of 85 Windows 2000 Professional computers and two Windows 2000 Server computers named Vancouver and Kelowna. Vancouver 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 Vancouver, you install and configure the Network Address Translation (NAT) routing protocol on the Vancouver server.

You decide to use IP addresses in the range of 172.20.20.1 through 172.20.20.150 for the network. Vancouver is config.to use an IP address of 172.20.20.1

Kelowna is a Web server configured with an IP address of 172.20.20.2 and a default gateway of 172.20.20.1. You want to allow Internet users from outside your internal network to access the resources on Kelowna through the NAT service on Vancouver.

How should you configure the network to accomplish this goal?

A. Configure the NAT routing protocol to enable the use of the network applications, specify the web server as the name of the application use web port numbers as the remote port number.
B. Configure the public interface of the NAT routing protocol to use an address pool with an address of 172.20.20.2
C. Configure the public interface NAT routing protocol to use a special port that maps the web server port to IP address 172.20.20.1
D. Configure Vahcouver so that it has a static route on the private network of the private interface use a destination address of the 172.20.20.2 a network mask of 255.255.255.255 and a gateway 172.20.20.1
