Summary: A good book, but you need the course material to score high
Review: A good resource book, I used this book with the course book to study and pass the CIT exam. You need the course material and experience to pass this exam.

Summary: This book has everything you need to pass the CIT
Review: Hear me know, believe me later: There was not one subject on the CIT exam that was not covered in this book! Be forewarned, it doesn't prepare you for the ridiculous phrasing and grammer used in the test to throw you off. I don't think any book can do that. Only real world experience can help you though those. If you used this book as your main study guide and failed the test, it is because you didn't study enough.

Summary: Easy to read, but not good enough
Review: I bought this book 5 days before I took the exam. I thought it was a good one as many readers rated it 5 stars. I passed the exam but I found it did not help me any. I passed the test because of my experience as well as using other books. I totally agreed to one of some other comments, this book lacked of explanations of many debug and show commands. After all, it is easy to read but not good enough to help you prepare the exam.

Summary: Too Much Filler; "Troubleshooting Lite"
Review: I bought this book as a companion to my Cisco Press troubleshooting book, but in the last few weeks, I found myself referring to this book less and less. There is some good information, but if you are taking CIT as your last or next-to-last exam, a good deal of material is copied directly from the earlier Sybex books in the series. Nothing wrong with going over the material -- after all, you're learning to troubleshoot the material you've learned previously -- but I felt like a lot of this book was simply regurgitating earlier books instead of giving me fresh insight. As I said, there were some good points. The chapter on troubleshooting methodology had some good examples, and having screen output for the commands helps those who don't have routers of their own to experiement with. Even that goes to extremes, though. At times there are pages and pages of redundant screen output when they need to be putting more solid information in. Also, there's not much information on the actual contents of frames in different protocols. For those of us working with CCIE in mind while working on our CCNP, that's detail that shouldn't be left out. Overall, the lack of detail in this book really surprised and disappointed me. You might very well be able to pass the exam with just this book if passing the exam is your sole goal. For those of us looking for more detail (and the exam has plenty of that!), I would recommend the Cisco Press book over this one.

Summary: Passed the exam with ease. Has al the info for the CIT exam.
Review: I passed the CIT using only the Sybex CIT Study Guide and Sybex CIT Notes book. I recieved a high passing score the first time I sat the exam. I recommend it highly.

Summary: Good book, but lacks explanations on show, debug commands
Review: I passed the exam with a 907, but I feel the actual course material gave a much better explanation of show and debug outputs. About one third of my test was ISDN related and I don't feel he covered this subject adequately. Other than that it was an easy book to read.

Summary: This book has great information, and I passed the CIT exam!
Review: If you want to know what is on the CIT exam, buy this book. Plus it has great Cisco troubleshooting information.

Summary: Needs less quantity and more quality
Review: Make sure you take a good look at this book before you purchase!At first sight it appears useful since it touches on most of the important topics. Unfortunately, "touch" is the operative word. Much of the book is filled with Router outputs that have little and in many case NO accompanying explanations. I consider this to be unacceptable. The treatment of the more complex topics, such as OSPF and EIGRP to name just two, is so scant as to be insulting to the reader. It appears as if the book was either thrown together very quickly or that the authors lack the necessary quality. In either case, it is just not good enough.
