"it legal or illegal that's a bit black and white. Why would a braindump be illegal and troytech and even transcender be legal?"
Because braindumps rely on people memorizing questions from the exam, and then posting them. That means, actually test questions are on braindumps. This is explicitly against the agreement people accept when taking an exam.
Transcender has a team of people developing questions based on the material and objectives Microsoft says is going to be covered. These are not actually test questions. Yes, sometimes they are close, but that is because there are only so many ways to ask a question on material.
"And about Microsoft policy? Are they goin to pay my salary? Guess not!"
Just becuase they are not going to pay your salary, I don't beleive that give you the right to cheat on their tests. The SAT board didn't pay my salary, but I didn't cheat. But hey, to each his own.
The more people that pass them, the less the test means to potential employers. So by promoting braindumps, you are in fact hurting yourself. But another way to look at is, MCSE or not, most of the tasks today can be performed by some fresh kid, at a salary way lower than yours.
