Question:
(a) What is Network Address Translation (NAT)? Why is it used?
(b) Given a following information by your ISP about your newly acquired Frame Relay connection:
Global IP address: 202.123.21.120 /30
You are required to design a network which constitutes of a LAN having 3 subnets (with Internet connectivity) for each department in your company.
Each subnet is assumed to have each a maximum of 28 hosts including a file server and an internal web server.
Note: You must use an internal Class C addressing scheme.
Draw the network layout and giving maximum information about:
• IP, Subnet Mask & Gateway addresses of all devices and servers and 1 host from each subnet.
• Type and hierarchy of hardware devices, transmission media and network topology you might adopt, with justifications, where necessary.
