Question 9

How many Class C networks does the summarized route 192.168.134.0/22 cover?

    Correct Answer: B

    The summarized route 192.168.134.0/22 covers 4 Class C networks. The /22 subnet mask means we are using 22 bits for the network portion, which leaves 10 bits for the host portion across the third and fourth octets. Converting this to the affected range of Class C networks, we start at 192.168.134.0 and the range extends to 192.168.135.255. Therefore, the networks covered are 192.168.134.0, 192.168.135.0, 192.168.136.0, and 192.168.137.0, making it 4 Class C networks.

write the network ip and subnet mask in binary: 192.168.100001(10).00000000 255.255.111111(00).00000000 so what are the propabale bits for the last 2 bits in octet 3? it is 00,01,10,and 11 Those are the 4 networks which will be 192.168.(132,133,134,135).0 answer is 4 for sure.
