Hello,
From all those who have taken the current CCNA exam, which type of subnetting questions did you have? Does the exam focus on a particular class (Class C hopefully). Were you required to hammer out all the subnets available in a class A range? Any tips on increasing subnetting speed (memorizing powers of 2)?
Thanks in advance.

I use the 256- (number you want to increase by).
hmm, let me explain....
you want to go up in 8's? then it's 256-8 = 248
so 255.255.255.248 will be
..0 ..8 ..16 ..32 etc
if you're doing it to a class b it's the same. lets try going up in 4's instead... so, 256-4 = 252
255.255.252.0if was start at 172.16.0.0 then you would get
172.16.0.0 172.16.4.0 172.16.8.0 172.16.12.0make any sense?
I use this method pretty much entirely.
when i did it was just class C
with a 255.255.255.240 mask
