a) Assign IP network address to each of the networks (N1, N2, and N3) where the size of both network N1 and N3 is the same but must be smaller than N2. Please justify your answer.

b) Using your answer in Q3 (a), label each of the network interface card (NIC, e.g. IFn) and assign an IP address to each of them. Please justify your answer.

c) Construct all the necessary routing tables if Host A is able to communicate with Host C (two-way communication).

(d) Using your answer in Q3(c), suggest the necessary network analysis steps when: (i) Host A is not able to reach Host C and when Host C is not able to reach Host B.
