First of all, sorry to hear of your disapointment. There are MANY pitfalls
in the CCIE Lab. The questions kind of force you into a corner but you will
never see them (the gotchas, or "issues" as Caslow puts it) if all you are
looking for is a working result, not the right answer.
Also, you have to think about the way points are lost. You miss one small
bullet, there goes 5 points. Very easy to bleed 20 points man... you only have
to get four 5 point questions wrong or five 4 point questions wrong... very eas
y
to bleed points.
I can think of one EXCELLENT example of something that works that is incorrect.
In BGP, you may be asked to allow only routes passing through AS 200. If they
are sending you stuff passing AS 200, 300, 45, 89 and 76, you will be set with
something like:
_200_
but, this will also get the desired result
200_
Which one is WRONG? The bottom one. Why? Because bottom one will also match 120
0
and 2200 and 19200 etc. etc. You DID get the thing to work, but, it clearly
indicates amateur thinking. This is the sort of attention to detail you have to
pay in the lab to make it. Little tiny mistakes hurt you bad. And it is better
in the one day format. Think about this... in the one day format you had to com
e
up with your own IP scheme. Imagine misplacing an IP address? You are screwed.
It does not matter if you KNOW IT... come on, EVERYONE gets an IP address
wrong... I do it regularly :-)) But in the lab, they will they will cut you
deep! ;-)
Another example is you are asked to allow a /24 network for example, some peopl
e
will use a reverse mask of 0.0.0.255 and some will use 0.0.0.0 (just an example
,
not to scale :-)) The latter will lock in the NETWORK... whereas the former wil
l
allow also /25 .. /26 .. /27 etc. You get the idea; both work, one is correct
(or better).
Hang in there. Some of these things will play a more important role your next g
o
round. So learn from [your] mistakes, lick your wounds and go for it again soon
.
Don't let it get you down.
Disclaimer: I am only trying to make a point. The examples given above have not
been tested in a lab scenario and may be wrong... hahahahaha
P.S. If you really KNOW FOR SURE you got all questions right as you mention
(don't know anyone who can claim that with any certainty) by all means fight it
with Cisco. This is the reason for them to allow you to re-grade.
Sincerely,
