Sub-net means 1.
Host means 0.
Representation of 192 in binary is 11000000.
Here class C has no use.
So as said before sub-net means 1 so as we can see above we got 2 ones.
So answer is 2.

I can't understand this question that how the answer is 2.

Hello Rakesh, I am very sure the answer is 4. Unfortunately, 4 is not one of the options here.
Since there are 2 ones, the number of subnet would have been 2^2. I mean the square of 2. But if you say host address per subnet then it would have been 2, i.e. 2^2-2=2. Thanks.

Class C -> N.N.N.H.
192 -> 1100 0000 -> 2 H bits are borrowed to N bits.
So, N.N.N.NNHH HHHH.
1100 0000.
No of subnets should be 2^n -> 2^2 = 4 subnets - not there in option.

255.255.255.192.
-> 255.255.255.11\000000.
2 bits are borrowed for sub net this means when the two bis are:
00, 01, 10, 11 we have 4 sub nets.
With the formula 2^x = no of sub net =-=> 2^2=4.
The right answer is four sub nets.

Yes @Mearg.
The correct & final answer is 4 subnets.

Yes @Shewangizaw.
The answer should be 4.
The answer should be 4.

Simply 2^2-2 = 2.

2^2=4 that is the answer.

Given: subnet mask 255.255.255.192.
Block size 256-192 = 64.
Possible subnets are x.x.x.0, x.x.x.64, x.x.x.128, and x.x.x.192.
Hence the answer should be 4 subets.
