Networking Concepts第 16 / 100 题
A /24 network needs to be divided into four equal subnets. Which new prefix length should be used?
a./25
b./26
c./27
d./28
解析
Borrowing two host bits from a /24 creates four subnets, resulting in a /26 prefix. Each /26 subnet provides 62 usable hosts. The formula 2^n subnets requires n borrowed bits, so 2^2 equals four subnets.
