Sun Certified Solaris(tm) 9 System and Network Administrator All-in-One Exam Guide
Paul A. Watters
This book will definitely help you pass the exams (three total). Very informative and easy to read and understand. There are a lot of practice questions that are helpful when it comes to comparing them to the test. I passed all three tests on the first try in the 90 percentile on each. Highly recommend this book.
