Good certification source.

A useful certification to have if you want to get a foot in the door in the I.T industry, also good to have if you are just learning as part of a hobby and feel the need to prove your self worth? (maybe bit too in-depth, deep in thought)

One of the better, if not best, places to go for questions, testing and so many other resources for professionals and those seeking.
