70-218 Q of the Day Wed 7/23

| Okay, hope this one is a little more challenging. (Worked on it for a while!)
Tarzanboy works as a Network Administrator of a Windows 2000 network. The network consists of thirty Windows 2000 Professional computers, and two Windows 2000 Server computers named Server 1 and Server 2. Server 1 has a permanent cable modem connection to the Internet.
All Windows 2000 Professional computers on the network are configured to use Automatic IP Addressing (APIPA). The network does not have any DHCP server.
To allow all the Windows 2000 Professional computers on the network to access the Internet through the cable modem connection on Server 1, Tarzanboy installs and configures the Network Address Translation (NAT) routing protocol on Server 1.
He decides to use IP addresses in the range of 192.168.40.1 to 192.168.40.50 for the network. Server 1 is configured to use an IP address of 192.168.40.1.
Server 2 is a Web server, configured with an IP address of 192.168.40.2, and a default gateway of 192.168.40.1. His ISP has allocated two IP addresses, 207.46.179.16 and 207.46.179.17 to the network. He wants to allow Internet users from outside the internal network to use an IP address of 207.46.179.17 to access the resources on Server 2 through the NAT service on Server 1.
How should Tarzanboy configure the network to accomplish this task?
A) Configure Server 1 with a static route on the private interface of the NAT routing protocol. Use a destination address of 207.46.179.17, a subnet mask of 255.255.255.255, and a default gateway of 192.168.40.2.
B) Configure Server 2 with a static route. Use a destination address of 192.168.40.1, a subnet mask of 255.255.255.255, and a default gateway of 207.46.179.17.
C) Configure Server 2 to use multiple IP addresses. Assign the additional IP 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 subnet mask of 255.255.255.254. Reserve the public IP address 207.46.179.17 for the private IP address 192.168.40.2.
Good luck! See you tomorrow with the answer!  | |

| Had a lot of looks, but a real low response. Too hard?

As the question states that you want to allow external Internet users to access the resources on Server 2 on the LAN through the NAT service, so you have to configure Server 2 as follows:
Address of the NAT server should be configured as the destination address on Server 2. So that during the packet transfer, packets must reach the NAT server, which changes the private IP address of that packet to the public IP address.
You have to configure the two network adapters on the NAT server. The first, as the internal adapter for the LAN, and the second should be attached to the router connected to the Internet. The second adapter has to be configured with the public IP address that is provided by the ISP.
The default gateway should be configured on the second network adapter with the IP address 207.46.179.17, rather than 207.46.179.16, as it is mentioned in the question that you want to allow the Internet users to use IP address 207.46.179.17 to access resources on Server 2.

Sorry, no new QoD today, my Server room has an A/C problem and it is 87 degrees in here! (Was over 90 when I came in this morning!) Hope to have the A/C back up and running tomorrow. | |
