My review of the 2nd edition to Amazon.com follows: (2 stars) Not what I would expect out of a study guide The first edition was heavily knocked for mistakes, so I bought this hoping for improvement. There were still quite a few mistakes I saw, especially in chapters 2 & 3; but I've bought other Cisco books with mistakes - this one has more than I owuld want, but that's not one of my main 2 reasons for the bad review. Reason #1: in some of the chapters, the material is disorganized. Points are repeated, but without learning impact, because it looks like several contributors writing about the same topic, with those chunks piled one after the other instead of organized and edited into something that flows. I especially found this disappointing in chapters 2 & 3, although there were other chapters (like the DLSw) that were written better. Reason # 2: the questions have answers, many of which are wrong in my opinion, but NO EXPLANATIONS!, which I cannot forgive in a study guide. I didn't rate this a "1" although it was borderline, because you can get some good info in some areas IF you are prepared to spot & weed out the incorrect info. Personally, I am now planning on spending more time reading Halabi (Internet Routing Architectures), Doyle (TCP/IP routing), and Caslow (Bridges, switches & routers). ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
