Quick subnetting question

What are the first two subnets for IP address 195.15.64.0/28

A 195.15.64.0

B 195.15.64.8

C 195.15.64.16

D 195.15.64.32

E 195.15.64.64

I would like to check this out with someone as there's no mention in the question whether subnet 0 is being used and it doesn't 'direct' you either as it gives you the choice of subnet 0 and the 2nd subnet.

The test engines answer is C+D
My answer was A+C

Well, if the answer was C & D then I guess it didn't want you to use subnet zero. If it did then you would have been right.

To put your mind at ease a bit, I've seen in these posts more than once that the Cisco exams won't be that vague...they will indicate whether to use subnet zero or not...

durant: I hope you are right, because I would picked A and C.

The CCNA exam will make it clear what they want to know as long as you read the questions carefully.

I would have done the same if I had come across that question, plus the cisco routers come with "ip subnet zero" on by default (I think)...have to verify that though...

Not the ones I used to setup.

Hey just relax, the test will not try to trick you! Experience and study is all you need, not ESP!
