Query: Insufficient information to pass the exam.

This book or any other book for that matter is not enough to pass IIS4 exam till date. What's with the IIS3 CBT...? also the edge test is not having any simulations. Even by ignoring the above two, the content of the book is not coping with the exam. Chapter 13 need to be elaborated with error codes of SQL server so is SMTP with domains. Finally the whole book needs to be revised. Reading this book page to page along with several other books (including Transcender material and Microsoft online documentation) paved my way to pass the exam.
