Q:

The network with ip address 192.168.100.0/27 is to be used on a router. If ip subnet-zero is configured, which statement describe the resulting number of available subnets and hosts?

A) 7 usable subnets, each with 32 host addresses B) 8 usable subnets, each with 30 host addresses
C) 8 usable subnets, each with 27 host addresses D) 7 usable subnets, each with 24 host addresses
 
Answer & Explanation Answer: B) 8 usable subnets, each with 30 host addresses

Explanation:

Because subnet zero is configured and we have a class C address (192.168.100.0) then the network portion will have 3 bits so 8 subnets will be available. The rest of the bits, 5, represent the available hosts, so 2^5=32, but only 30 are available, 0 ad 31 are network and broadcast respectively.
