### Discussion :: Networking - Section 8 (Q.No.27)

27.

You have a network ID of 134.57.0.0 with 8 subnets. You need to allow the largest possible number of host IDs per subnet. Which subnet mask should you assign?

 [A]. 255.255.224.0 [B]. 255.255.240.0 [C]. 255.255.248.0 [D]. 255.255.252.0 [E]. 255.255.255.255

Explanation:

No answer description available for this question.

 Raj Gopal said: (Aug 24, 2015) A is right answer since three bits are borrowed (128+64+32) = 224.

 Shewangizaw Bogale said: (Jan 5, 2017) Yes, A is the Only correct Answer.

 Shewangizaw Bogale said: (Feb 18, 2017) 8 subnets, 8 = 2 ^3, so the network bits(N) is = 3, so the subnet mask is = 11100000 in binary and 224 in decimal notation. So, the correct Answer is A . 255.255.224.0.

 Iglooroy said: (Apr 20, 2017) The correct Answer is A.

 Sandeep Singh said: (Apr 22, 2017) 2^n-2= subnet for eight we need 4 bits i think but 255.255. 255.255.240 is the answer.

 Obaid said: (Sep 13, 2018) @Sandeep. 2^n-2 is the formula of valid hosts not for the subnet, so n=3 is correct and A is a valid answer.
