You have been asked to come up with a subnet mask that will allow all three web servers to
be on the same network while providing the maximum number of subnets. Which network
address and subnet mask meet this requirement?

A.
192.168.252.0 255.255.255.252

B.
192.168.252.8 255.255.255.248

C.
192.168.252.8 255.255.255.252

D.
192.168.252.16 255.255.255.240

E.
192.168.252.16 255.255.255.252

Explanation:
A subnet mask of 255.255.255.248 will allow for up to 6 hosts to reside in this network. A
subnet mask of 255.255.255.252 will allow for only 2 usable IP addresses, since we can not
use the network or broadcast address.
