person one :
How I did it and what percentage each played in the success of the exam:
Transcender: 50%
Exam Cram: 15%
NT Resource: 5%
Brain Dumps: 25%
Hands on: 5%
I charted out the subnet matrix (only class C hosts) and then when I got a question concerning a Class B address I calculated the B hosts real quick with the calculator (took 30 seconds and I was way ahead on time)
Lots of folks make this step a lot more complicated than it is. If you can remember 192 - 2 - 62 everything else is a mathematical progression from there. To get the amount of B Hosts just take the number of C Hosts (not VALID C hosts, all C Hosts, ie. 64 not 62) and multiple by 256 and subtract 2. To get number of A hosts take C hosts and multiply it by 256 and 256 again and subtract 2. Simple huh?
