The client and server operating systems in use.

Scenarios
From the following real scenarios choose the appropriate protocol:
You want to install a NT network for a company that has its offices in Mumbai Pune and Nasik. It wants to host a web server and allow Internet access to all staff.
You are adding some NT server to a largely NetWare environment.
You have to install a small LAN with 8 workstations running on Windows 95 and a single NT server.
Your current network is mainly Novell but:
You plan to install some NT servers to run Exchange and SQL server.
Your WAN links are not as fast as you would like them to be.
Amongst your priorities getting the most out of performance is the top most.
Your staff also needs to access the Internet.
