Been following the forums, but have never posted. You had better be prepared for the 291 or it will beat you down. I have failed miserably twice, and I thought I was pretty well prepared. The questions are very lengthy and I would recommend having plenty of time to devote to it along with a clear and fresh mind. I have gotten down subnetting along with a lot of the other objectives, and have the MS press book now and it seems pretty good. I plan on doing the labs(I do want to pass this test right)? I also bought the exam cram book for 291 because it looks readable and it seems pretty good after skimming through a copy of the book in our IT lab at work. Anyway, good luck to everyone, this exam is no gimme. I do however plan on taking it and passing by the end of this year, and probably before then. Much studying to do, good luck to everyone.
