Q) Consider the following network; some of the interfaces are marked with their respective IP and MAC addresses.

Answer the following in detail

(1) Computer B requests some web contents from web server E

What would be the destination MAC address in frame header between computer B and switch A?

What would be the destination MAC address in frame header between switch A and router A?

What would be the source MAC address in frame header between switch A and router A?

What would be the destination IP address in IP header between computer B and switch A?

What would be the destination IP address in IP header between switch A and router A?

What would be the source IP address in IP header between switch A and router A?

What would be the source and destination IP address in IP header between router B and router C?

What would be the source and destination MAC address between router B and router C?

What would be the destination MAC address between router C and switch B?

Are the interfaces between router A and router B belong to same network?

(2) Computers A, B and D request some multicast video traffic (requiring 2 Mbps for a single stream) of same group from server E, multicasting is enabled and all the devices are configured accordingly

a)What would be the data rate between switch B and router C?

b)What would be the data rate between router C and router B?

c)What would be the data rate between router A and switch A?

d)What would be the data rate between switch A and computer B?

e)What may be valid destination IP address/addresses on the links connecting computer B and computer E?

(3) Answer all the above questions of section (2) i.e., (a, b, c, d, e) in the case when multicasting is not enabled NOTE: Keeping in regard to concept of Computer Networks, thank You.
