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. Which one of the following statements is true?

Show answer & explanation
Correct answer: C. A assumes B is on the same network, but B assumes A is on a different network
Explanation
With A's mask (/17): A → 203.197.0.0 and B (75 < 128) → 203.197.0.0, so A sees B as local. With B's mask (/18): B → 203.197.64.0 (75 AND 192 = 64), while A → 203.197.0.0 (2 AND 192 = 0), so B sees A as remote.More Data Communication and Computer Networks questions
