BSCN/Routing 2.0 Test QuestionI've only been doing the pure networking side
(not desktop or servers these days, just pure routers and firewalls) for the
last year. I'd say I've seen at least 3 sites that had problems due to
subnetting misconfigurations (or would have, if I hadn't spotted it). One
such problem was with PacBell and a block of IPs that went 2 above the
actual subnet range. It happens, but if you don't know it you'll never spot
it unless you're constantly plugging it into your subnet calculator. In the
PacBell case, I spotted it right away as a /27 only gives you 30 usable
addresses, and they listed 32 (and no, not just the network - broadcast
range, but the first usable host to that last usable host, plus 2).

Well, I believe you dont use subnetting enough then if you think a
calculator is needed. Once in the industry you will live by it and you
should be able to do it in your head for the most part. Even VLSM which is
just the subnetting of subnets. Forget calcs its not that difficult.

took it this morning and passed with a 759, not awful for doing it in 10
days. There was one subnetting question about # of host, no big deal, and
there was some on vlsm and summarization, but very easy questions on it.
now about that bottom line you wrote.....i can think of nothing worse than
live to subnet, : ), thats what calculators are for

I don't remember much straight-up subnetting, but if you read the exam
objectives, this exam does cover VLSM and route summarization. If you have
trouble doing 'normal' subnetting, these will kill you.
Learn to subnet, live to subnet, love to subnet!

Hey,
Just wondering if anyone knows how much subnetting there is on this test,
with questions such as determine the # of networks/host/broadcast address of
a given ip address
thanks!
