joining dissimilar networks

I was given the following question, and am rather stumped:

bb.A graphics design firm is currently using computers running several different operating systems on separate local area networks (LANs) and wants to combine them into a single internetwork. They also want all users to be able to access the Internet through the network. The graphic artists in the firm use Macintosh computers that are connected to a TokenTalk LAN running the AppleTalk protocols. The bookkeepers, administrative assistants, and executives all use Microsoft Windows 2000 and are connected to a separate Ethernet LAN running NetBEUI. You are designing the new internetwork, and you have decided to use IP as the network layer protocol for all of the computers. Which of the following procedures must you perform in order to join the LANs into a single internetwork? (Choose all answers that are correct.)

1)Convert all of the computers on one of the LANs so that everyone is using the same data-link layer protocol.
2)Install a router connecting the two LANs together.
3)Assign IP addresses to all of the computers on both networks.
4)Install a Dynamic Host Configuration Protocol (DHCP) server to configure the computers with TCP/IP configuration parameters.
5)Install a router connecting the internetwork to an Internet service provider (ISP).


My own guess would be numbers 1 & 5, but then again, I am feeling very dumb today.

sounds like 2 & 3 to me.

If you wanna use IP then each and every machine needs an IP address.
Since it is stated that there are two separate LANs then you need a router.

1) is not correct because there isn't any datalink protocol you can use that would allow all of them to communicate, because they are separate networks. They are even separate types of networks. For all intents and purposes you need a router to let them communicate. You could bridge them but man that would be messy. (wanna stump your teacher? Tell them you could use a source route translational bridge (SRTB) to combine the ethernet and token ring into a single IP network/broadcast domain)

2) two networks (lans) need a router to communicate using IP or any other routable protocol

3) you want IP, need IP addresses

4) while good practice and really what you should do...it is NOT necessary. splitting hairs on this one

5) nowhere in the description does it say internet access. not needed.

hope that helps. Answers are 2&3 but one could twist some of the others to suite the problem.

ps - do mention using a SRTB and single IP network/broadcast domain instead of a router and see if you teacher starts uttering the words "bah, bah, huh?"

The ppl using netbeui on Win 2K would have problems with a router; their machines would need to be changed to use TCP/IP as the default protocol. NetBEUI isn't routable.

What's the question from? MSCE 70-210 or Network+, maybe?

That was stated in the problem, that they were moving to an IP network.

Router. Of course you'll need the correct interfaces on it for both types of network. And don't forget that each network segment must be on a different IP subnet.

3) you want IP, need IP addresses
can't you just let the router assign I.P.'s . you wouldn't want to search for a comp on the network by I.P. but you could use names.

3 and 5.
2 is a possibility if you want to maintain separate LANs

You need ip addresses.
The question says CONNECT TO THE INTERNET.
NetBUEI has to go.

It does say they need internet access though:
