You are required to design a network layout which constitutes of a LAN having 3 subnets (with Internet connectivity) for each department in your company.

  • Two of the 3 subnets are assumed to have each around 50 hosts, inclusive of a file server, an internal web server and a network printer.
  • The 3rd subnet is to be connected using a wireless Access Point and all the hosts (around 20) on that subnet are assumed to be Wi-Fi ready.
  • Finally, all 3 subnets should make use of dynamic addressing.
  • Draw the network layout and giving maximum information about:
  • IP, Subnet Mask & Gateway addresses of all devices, servers, printers, and 1 host from each subnet.
  • Type and hierarchy of hardware devices, transmission media and network topology you might adopt, with justifications, where necessary.
