subnet phrasing question

Aquabat [banned]

i've come across a question in the ccna prep center icnd practice test. It asked for how many usable hosts and subnets in the subnet mask 255.255.255.240
How do i answer that, it doesn't give an ip address along with it, should i just assume they mean class c based on the multi-choice options?

I would say unless the question specifies i.e. 172.16.0.0 & 255.255.255.240 then go on the basis of the multiple choice answers and that it is a C Class address

****EDITED TYPO*****

In this case 16 usable networks and 14 usable hosts on each network

14 and 14 if subnet zero is disabled, but again this should be specified in the question

It's a pretty poor question and I doubt you would get a question like that on the actual test simply because there could be several correct answers depending on whatever class you chose to subnet.

Isn't it 16 subnets and 14 hosts per subnet with subnet-zero enabled?

Yeah sorry, 16 subnets - got a case of fat fingers

At least something i've been studying today has sunk in.
