An engineer is performing the IP subnet design for an organization and needs to find the best mask that should be used. The organization has been assigned the 172.16.44.0/22 network. The addresses must be split up so that they can be equally organized into 16 subnets of at least 50 addresses. Which mask would best fit this requirement?
A) 255.255.255.128
B) 255.255.255.192
C) 255.255.255.240
D) None
B
Explanation: C) The 172.16.44.0/22 network provides up to 1022 total host addresses. To split this equally into 16 different subnets of at least 50 addresses, the engineer can use the 255.255.255.192 (/26).
