A server administrator needs to configure a server on a network that will have no more than 30 available IP addresses. Which of the following subnet addresses will be the MOST efficient for this network?
Option C: 255.255.255.224 uses 27 bits for the subnet mask, which provides 2^(32-27) - 2 = 30 available IP addresses. This subnet mask is the most efficient choice for this scenario because it uses the exact number of bits needed to provide enough IP addresses for the network, without wasting any addresses.
