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 192.69.24.128/25 network. The addresses must be split up so that they can be organized into at least 8 subnets of at least 6 addresses. Which mask would best fit this requirement?
A) 255.255.255.192
B) 255.255.255.248
C) 255.255.255.240
D) 255.255.255.224
B, C
Explanation: B) The 192.69.24.128/25 network provides up to 126 total host addresses. To split this into at least 8 different subnets of at least 6 addresses, the engineer can use the 255.255.255.240 (/28 ) or 255.255.255.248 (/29 ) mask. The options are to use 8 subnets of 14 or 16 subnets of 6.
