In regards to your prediction your right, it will take some time, and people
will adapt. Without breaking NDA, the reality is, they did add switches as
they disclosed, but the approach people are taking needs to be changed as
well. I failed my 3rd attempt in SJ yesterday, my first shot since the
changes, last attempt was in May. I can tell you the way people are used to
preparing with the current vendors labs, will not get you through the new
lab if you base your preparation on the lab after lab approach, or do as
many as possible. The guys that sell these labs know that they are just a
way to demonstrate and refine what you already know about the technology
from research coupled with practice. So those who are basing your knowledge
on doing vendor lab after vendor lab, you will be shocked at your first shot
at the new lab.
With that being said, others are right, the technologies are the same and
you have to know them inside and out. There is no substitute.
As for my attempt, I feel I did really well, I think this was my strongest
performance. After I got past the reality of the differences from my
previous attempts, and vendor labs, I focused on what I knew. After I did
this pieces started to fall into place. I left one stone untouched, that
could have broke connectivity, and it wasn't worth if for me. I finished
with time to spare, and had I not had a problem with a misbehaving switch
(don't waste too much time if you know it's right, reboot), I would have had
at least 2 hours to verify. So whats next for me is to dig a little deeper,
focus on what I missed while keeping what I nailed fresh in my mind, I've
scheduled Jan 19 if I can come up with the cash by then.
Dave, if YOUR reading this, it was a fluke deal, give yourself a month and
take it again, you will get it.
HTH, and best regards,
Nick Griffin
