Query: Excellent book. Recommended!!!

This book is far better than the Exam Cram or Test Success books. First, it provides the infamous scenario-type questions that the other two books do not contain. Second, the explanations for the answers are concise, yet complete, even for the incorrect choices, and citations for further reading are also given. Third, the book provides the reader with extensive suggestions for how to practice on the real system, in order to prepare for the exam, at the beginning of each section. I plan to purchase this book, if available, for my remaining certification exams!
