Q. How many bits are borrowed from the host portion in a /24 subnet to create 4 subnets?
A.
1
B.
2
C.
3
D.
4
Solution
To create 4 subnets, 2 bits must be borrowed from the host portion (2^2 = 4).
Q. In a /16 subnet, what is the range of valid host addresses for the network 172.16.0.0?
A.
172.16.0.1 to 172.16.255.254
B.
172.16.0.0 to 172.16.255.255
C.
172.16.0.0 to 172.16.0.255
D.
172.16.1.0 to 172.16.1.255
Solution
In a /16 subnet, the valid host range is from 172.16.0.1 to 172.16.255.254, with 172.16.0.0 as the network address and 172.16.255.255 as the broadcast address.
Q. In a network with a subnet mask of 255.255.255.128, how many hosts can be accommodated?
A.
126
B.
128
C.
254
D.
256
Solution
A subnet mask of 255.255.255.128 corresponds to /25, which allows for 2^(32-25) = 2^7 = 128 total addresses. Subtracting 2 for the network and broadcast addresses leaves 126 usable hosts.
