Summary: Passed the Support exam, the hardest exam in the CCNP series
Review: This has got to be the hardest exam in the CCNP series. I was sweating bullets. I am thankful for this book, as it did prepare me, but you really have to study hard to pass this exam. If it wasn't for this book, I would have failed for sure, but I did get a 890, which is awesome for this exam. This exam hits hard on ISDN troublshooting. Read the ISDN chapter in this book at least twice before taking the exam. You'll pass, but you have to do some work too! Good luck

Summary: A fine book
Review: This is a good book with a lot of relevant information; I definitely recommend it to others. However, it does have a few errors and the sample questions are not as difficult at the actual exam. I found that the exam itself was poorly worded and confusing. It seems weird to fault the book for having better grammar and logic in their sample questions then the actual test...but, whoever said life was fair.

Summary: I just keep moving towards my CCNP with Sybex!
Review: This is a great written book and it really helped my understand the ISDN troublshooting technique that is so difficult on this exam. To pass the Cisco CCNP Support exam, you MUST know your troubleshooting techiques for ISDN and Frame Relay realy, really well. Everything on the exam was in this book. I recommend this book for the exam and for a desk reference as well. It is the largest Cisco book I have bought from Sybex, so be prepared to read and read some more. Also, having routers and switches is the key to sucess on this exam.

Summary: Not good enough, but not totally useless
Review: Two reasons why I buy this book 1. I need to have some guide on the Support exam objectives - kind of like finding out roughly what Cisco really expects me to know before I click the start button. On this aspect, this book did quite OK. I have indeed compare it side by side with Sean Odom's exam prep and thought they have more or less the same coverage of topics - this book win simply because it is cheaper - not better. 2. I hope the end of chapter tests, assessment tests, might prove to be of some use - it does point out things that I overlook or cannot remember. Quite useful.***Ten reasons why you should not buy this book*** 1. If you use this book alone, you will fail. If you can pass Support with this book alone, then I am starring in TopGun II. 2. Frame-relay troubleshooting is given a criminally incompetent treatment - other than about 11 pages of uninspiring explanation of SHOW and DEBUG commands - no example or scenario is use to illustrate how to use them to investigate a network failure. Also, do not hold any hope that these authors would point out particular issues to watch when using OSPF, and when using distance vector routing protocols, in a frame-relay network. 3. With the exception of a couple of better written chapters, the rest of the book are just pages after pages of lifeless, uninspiring explanation of a big bunch of SHOW and DEBUG commands. There is little attempt to TEACH the subject in a better way, possibly because the subject itself has not gain ground and mature in the authors mind. You simply cannot be convinced that there is a guru behind those words. 4. Some SHOW command is overly lengthy to be useful: SHOW CONFIG - 6.5 pages - but has little value. Obviously even the editor is too busy to find time going through this god forsaken book - or may be they are trying to beef up the book to respectable thickness - like surely the content should at least thicker than the hardcover? 5. Too many corners are cut. Example. To check backdoor bridge, check the bad hop count in SH IPX TRAFFIC - but never tell us why. Similar cutting corners is populated throughout the book 6. Chapter 5 was exciting! And display some real troubleshooting at work - wonder which of the 2 authors did it. But Chapter 6 deteriorate to mere tabulation of SHOW and DEBUG commands without much examples or or any attempt in explaining how or when to use it. Very cheap shoot. This trend continues right to the end of the book. 7. Cut corner example#2 - do you know that there are only 4 pages on X.25 - where 1.5 pages are taken by SHOW INTERFACE, another page taken up by a useless table - leaving not much to talk about x.25 troubleshooting. 8,9, 10. etc, etc, etc. I think you all show go get a better book - probably cisco press? But if you are stuck in some corner of the world where books takes 9 months before it arrives from USA, I think this book plus Cormac Long's CIT should get you thruogh the Support exam.
