What is the maximum number of bits that can be used for subnetting, when the network address is a Class C address?
What is the maximum number of bits that can be used for subnetting, when the network address is a Class C address?
A Class C address consists of 24 bits for the network address, leaving 8 bits for the host portion. These 8 bits can be entirely used for subnetting. Thus, the maximum number of bits that can be used for subnetting in a Class C address is 8.
SORRY - I ready the question wrongly Answer B is wrong. The correct answer is A. Answer B is right for the maximum number of host bits which is: 2^8-2 = 254
Correct answer is B
This is a tricky question because Huawei allows 7 bits for subnetting. Anyway, I guess the answer should be A. https://support.huawei.com/enterprise/br/doc/EDOC1100058917/5952bfa4/example-for-configuring-an-ip-address-with-a-31-bit-mask
