You have class B network with a 12 bit subnet. How many subnets and how many hosts per subnet are available ?
a. 14, 14
b. 14, 4094
c. 4096, 14
d. 4094, 16
e. 4094, 14
Answer / indu
E
Explanation:
This is a tricky one. Even though your parent subnet is of Class B,
your network nodes extend beyond the Class B/Class C border (24th bit)
because you are using 12 bits subnets. Basically, you taking this
big network and splitting to many many little subnetworks.
Number of subnets = 2^12-2 = 4096 -2 = 4094 subnets
Number of hosts per subnet = 2^4 -2 = 14 hosts
