A	62 subnets and 262142 hosts.
B	64 subnets and 262142 hosts.
C	62 subnets and 1022 hosts.
D	64 subnets and 1024 hosts.

Question 117 Explanation:

It is a class B address, so there 16-bits for NID and 16-bits for HID.
From HID, we took 6-bits for subnetting.
Then total subnets possible = ( 2⁶ ) – 2 = 64
Total hosts possible for each subnet = (2¹⁰) – 2 = 1022

Correct Answer: C
