Hosts

I'm studying for the CCENT 100-105 exam.
My question is on hosts.

255.255.255.252 /30 mask = 252
There are 64 subnets and 4 hosts, with 2 usable hosts.
When I take the exam and get a question of the number of hosts per subnet will it ask for total hosts in a given subnet or just the usable hosts?

Hosts usually refers to usable. The other two are network and broadcast addresses.

I believe the keyword will be "useable" hosts vs "total" hosts. I think 99% of the time they will want useable hosts for subnet questions, like you need to create a subnet with X amount of "useable" hosts.

useable and total hosts would be the same though. Can't have a "usable" host PC on the network or bcast IP of a given subnet
