What subnet mask can be used to segment the 172.16.0.0 network to allow for a minimum of 6 subnets while maximizing the number of hosts per subnet?
A) 255.255.248.0
B) 255.255.224.0
C) 255.255.192.0
D) 255.255.128.0

Using a subnet mask of 255.255.224.0 will create 8 subnets with 8190 hosts per subnet. This will allow for a minimum of 6 subnets while maximizing the number of hosts per subnet. A subnet mask of 255.255.248.0 would create 32 subnets but with only 2046 hosts per subnet, which is less than the required number of hosts per subnet. A subnet mask of 255.255.192.0 would create 4 subnets but with 16,382 hosts per subnet, which is much more than required. A subnet mask of 255.255.128.0 would create 2 subnets but with 32,766 hosts per subnet, which is also much more than required.
