Re: Little Johnny has some ospf questions for ccie students.

Johnny,

"The people who have been to the new lab said we need to be
able to respond quickly and will not have time to think about things.
I hope my questions are not too hard."

Personally I consider it bad form to post 30 questions, without any
reference to where they originated, or any hint of effort at solving them
yourself. Have you had time to think about these, or are you just too
busy? How hard do you think they are, based on your previous work to solve
them? It is always best to specify where questions are from, as it allows
readers to verify that they originate from a legitimate source.

List members answer question on a voluntary basis, and that is entirely
dependent on their goodwill. Generally speaking, the quality of the
responses correspond to the quality of the questions, and effort
demonstrated by the questioner to solve and think through the problems
involved.

Paul.
