Summary: You'll need the exam prep book to fill in the gaps.
Review: I always thought I had excellent technical skills with over 12 years of hardware troubleshooting experience. I also though hardware and software support was fairly straightforward and easy to understand, that was until I started reading Cisco books.Coriolis has put together a book that begins to breakdown Cisco support and clear up my confusion. The Cram Sheet, tables, figures, screenshots, practice questions and sample test in this book are great ways to make the learning easier. Covering topics like resources, methodology, the technician's tools, protocols, frame relay, ISDN, IP, IPX, AppleTalk, and the Catalyst 5000 switch I have the beginning of a very goof foundation. I am anxious to read the Support Exam Prep book once published to fill in the details of the areas covered in this book. Visit Coriolis's website to find this and other certification books on several subjects.

Summary: Not enough for exam
Review: Purchased the book to help study for the CIT exam. Found it to be a very good book for studing the exam. There are a few mistakes and weak points in this book but over all it is a good review for the test. I do not think that there will be any 1 book out there that will prepare you for the CIT exam. You need a lot of practice and experience before attempting this exam. This book will help get your there but you have to do some additional reading also.

Summary: It's OK.
Review: Remember that this is an "exam cram". It is a refresher for those that already know the material. As such, it is a good enough book. If you don't already know the material or don't have at least a year of hands on experience, this book won't do the job. If the book alone is applied to the test, the best that you can hope for would be 70%. The book is mostly accurate, with few typos, but it does not cover everything.

Summary: Useful
Review: This book is not perfect - but among all the available SUPPORT references - this one appears to be more useful. The support exam is littered with dump questions, stupid answers - which literally cannot enter any self-respecting reference - so do not expect this book to cover every thing - but I suspect what this book covers would allow you to get a pass - since the passing mark is at a low 692/1000. Some of the things I find relevant are: 1.This is the only book that list the LED status of Catalyst module in a very compact, easy to study format - and being compact give you a chance to compare the differences to clarify the confusion. 2.Everyone talk about SAGE/SAINT/EARL - but only this book talk about MCP/LCP/Pheonix. 3.This is the only book that mentioned there is a command "show apple ADJACENT-route" - not many guru would have know this command out there. 4.I have came across many books that talk about the 4 loopback tests - this is the only one that gives the 4 IOS commands that did the loopback test - whatever happen to all the other authors - including the legendary Cormac Long? 5.He managed to trick me with one tricky question on SAP updates calculation - twice! 6.This is the only book that gave me ISDN bri port RJ45 pin out - not sure if this is exam question. 7.This is the only book that mentioned debug and show command that you can run on the Cisco router to troublehshoot VLAN/ISL problems - all other authors tunnel vision on the Catalyst IOS commands when they discuss Catalyst switch. 8.Most people provide OK explanation on Ethernet frame type - this author use precise diagram that left no doubt. 9. The end of chapters questions are OK - but I think it would have been better if it adds some packet/frame analysis type question. 10. There is some thoughtfulness when it come to organise those show and debug commands - I find that I can easily compare IP, IPX, Apple commands in 3 different chapters since simiar command occurs in similar place in each chapters. Wise remarks here and there appears to be exam relevant. But given the dumbness of the exam, I afraid this is as good a book on support as it can ever be when it comes to exam preparation. There is not much use for a book like this after the exam.

Summary: Good reference, but bad test prep
Review: While this guide provided quite a bit of useful information that I have been able to use frequently in my work environment, I do not think that it did an adequate job of reviewing the materials that I encountered on my exam. I passed the exam, but only by a slim margin, and only because of some material from other tests that I was able to remember. I cannot divulge the exact areas that I felt the book came in lacking due to the Cisco Confidentiality Agreement, so I can only say that this book alone will likely be inadequate as a sole test preparation resource. However, I would definately recommend this as a supplementary resource due to its potential real-world benefits.
