I think Peter was making that in jest... As I'm sure anyone who has gone
through the lab can figure out that there's not really an emphasis on best
practices or even 'good ideas' sometimes. ;) It's a technology-based exam
and people either understand the details of technologies or they don't!
Real life is relatively straight-forward... But where's the fun in that?
:)
Just my thoughts!

I hate to say it, but typically you see posts like that from NON-CCIEs, i
have never seen a CCIE make such comment.
