Guys I need your help, the manager at a company said in my interview that I have to design a network of 500 staff (note: every single one wont exactly have a PC) which he will compare with 6 other guys and who has the best overall design lands the job.

Help, I'm a CCNA not a CCDP or CCIE or even CCDA

The 5 main areas of the building are 1.Fire Department-2.Security(this has 20 stations)-3.Stores(where everything is tore)-4.Executive Management (HR,General Manager, Chairman, Secretary's,Chief Financial Officer,Accounts, etc...)-5.Energy Management (IT Manager,Network Manager,Electronics repair guys, two secretary's) and they will be communicating the other buildings of its similar structure in other locations but with 1/4 to 1/2 it's amount of people and size.

One Guess
I use one router for the whole network and 5 smart swithes, then use mac address to set access lists and restrictions and dhcp to supply IP address to eg: one batch of ip's for security


Thanks,
Awaiting your responses.
