Answer : What Network types,interconnection devices,Access methods, and Transmission Media should I Use?

First thing- Update to IE6 IE5 has many, many security holes.

Depending on the environment, and what sort of bandwidth you require:

You could use 2 routers, 1 on each network,with cat5 cable or fibre between, or 2 switches with fibre modules to provide a fibre backbone connection between the 2 networks.
The new building would then be able to share the leased line for building 1.

Or you could install a new leased line for building 2 and use VPN to connect them via the internet.

There are several other scenarios, including wireless, microwave, SDHSS modems, etc. but this smells like an old MSCE question paper to me :-).

I would RTFM.
