WARNING: - slight rant

I received a call today from a colleague who was freaked out as he didn't know how to hook up a CD and HDD as the MOBO I had spec'd only had one IDE Controller.
This guy is A+ 'certified'!!!
I'm sorry, but this (IMO) is basic stuff! I'm not opposed to helping someone out
(and I did btw in a professional manner), but it just fries me that someone who read a frigging book, can sit for a test, and then they freak out when they are assigned a project because they really DO NOT UNDERSTAND hardware!!
and they proudly display the frigging piece of paper that says they do
Some of you may have felt I've been 'short' with you in the past regarding your questions on A+ stuff. A+ is more than a mere test for beginners to get through!! There are a lot of things that an experienced technician KNOWS from Time in the industry (real experience) that cannot be learned in 6 weeks from books.
Even more, there are things that one learns by surving the next generation upgrades that turn out. Some things just take time!!

So my question to those of you preparing as well as anyone who has recently passed the A+ Core exam......
Do you understand how to set up a system with a CD and HDD when you only have a single IDE controller?
And for a second level question?
Why are you likely to only see 1 IDE controller today as opposed 2 IDE controllers from a board 3 years ago?
