Two computers A and B are configured as follows : A has IP address 203.197.2.53 and subnet mask 255.255.128.0, B has IP address 203.197.75.201 and subnet mask 255.255.192.0. What one of the following statement is true?

1. AA and B both assume they are on the same network
2. BB assumes, A is on same network, A assumes B is on different network
3. CA assumes, B is on same network, but B assumes, A is on a different network
4. DA and B both assume they are on different network

Show answer & explanation

Correct answer: C. A assumes, B is on same network, but B assumes, A is on a different network

Explanation

A uses /17: 203.197.2.53 and 203.197.75.201 both give 203.197.0.0 (third octets 2 and 75 are below 128), so A thinks B is local. B uses /18: B's network is 203.197.64.0 but A gives 203.197.0.0, so B thinks A is on a different network.
