1. You are an instructor of Computer Networking and have given an assignment to the students to configure a network with the following requirements:

The IP address space is 173.3.22.0 with a netmask of /24

There is one router in this address space and two PCs (A & B).

The router and two PCs are on the same Ethernet broadcast and collision domain.

You may use any of the IP addresses in 173.3.22.0/24

A student has submitted the following solution:

To grade this assignment, check on the communications and decide if and how each computer can talk (or not and why) to the other. Consider the netmask, ARP, Ethernet and IP.

A) Can B send an IP packet to R? if Yes, how, if No why not.

B) Can B send an IP packet to A? if Yes, how, if No why not.

C) Can A send an IP packet to B? if Yes, how, if No why not.

D) What grade would you give this student who is studying to be a network engineer? What if the address of A was 173.3.22.127/24?

A: 173.3.22.129/24 Router: 173.3.22.1 B: 173.3.22.2/25 Router: 173.3.22.1 R: 173.3.22.1/24 Ethernet
