You need to subnet a network that has 5 subnets, each with at least 16 hosts. Which subnet mask would you use?

A) 255.255.255.192
B) 255.255.255.224
C) 255.255.255.240
D) 255.255.255.248


B
Explanation: B) The correct answer is 255.255.255.224 because the only mask that would fit the requirements of 5 subnets and 16 hosts is /27, or 225.255.255.224, which provides 8 subnets and 30 hosts per subnet.
