Q
You need to subnet a network into 5 subnets, each with at least 16 hosts. Which classful subnet mask would you use?
AA. 255.255.255.192
BB. 255.255.255.224
CC. 255.255.255.240
DD. 255.255.255.248
Correct Answer:
B. B. 255.255.255.224
Explanation:
You need 5 subnets, each with at least 16 hosts. The mask 255.255.255.240 provides 16 subnets with 14 hosts which is less than 15, so this will not work. The mask 255.255.255.224 provides 8 subnets, each with 30 hosts so this may work. The mask 255.255.255.192 provides 4 subnets, each with 60 hosts so this may work. Comparing both the possible masks, 255.255.255.224 provides the best answer.
