Don't waste your time or money on this one. I went through the MS MOC classes, read Inside SQL (a must have for anyone studing for the MCDBA cert.) and then bought this book. I also read the Troy Techs. This book was way off of both tests, 70-28 and 70-29. To get it done, study the MOC materials, read Inside SQL, and work with the product as much as possible. But don't buy this book.
