Oh dang, you had to go and bring up the one thing I haven't figured a way around (so far) in a pbt scenario...

Good points, Alan.

Expanding Level 2 sounds like it could develop into something 
worthwhile, if the market needs, wants and supports it.

Practicum exams are very problematic though. I've always maintained 
that the Linux industry needs both CBT and PBT, but they do fall into 
two distinct areas, with some grey spots in the middle.

CBT is great for testing generic stuff, or vendor-neutral stuff like 
LPI does. It can work independent on any specific Linux 
implementation, so it's good for LPI's programs.

PBT can't work independant of an implementation - you have to have a 
real Linux system running to do the test. Therefore PBT is best for 
vendor taining, and excellent for testing candidates on a specific 
vendor AND version.

I don't see LPI managing to come up with a PBT exam that suits it's 
mandate - vendor neutral testing. There is no reference standard to 
measure against and a large part of a PBT test would be to ensure the 
candidate understands the quirks and customizations of one vendor. To 
illustrate, not many LPIC-1s will be able to pass this very easy PBT 
question using my current box:

Configure Apache to start and X to not start at boot up.

Why? Well, I run gentoo. That one little fact invalidates the entire 
test.
