Okay so you passed the CCNA exam and you're very excited, now what? You want to pursue the CCNP certification but are unsure of what to study. You want to make sure you get the best possible book for the greatest chance of passing first time around. Well CIT published by McGraw-Hill may be the choice.
The book is detailed in every topic. The authors have taken their expertise and put in a book that will have you troubleshooting Cisco networks in no time flat. Over 650 pages of examples to learn from along with questions, case studies and helpful hints are roiled neatly into one book.
The topics of methodology, tools and commands, diagnostic commands, LAN troubleshooting, Cisco Switches, WAN and WAN protocols, extensive coverage of TCP/IP, IPX, SPX and routing protocols along with ISDN and advanced trouble techniques makes this a great exam companion as well as a great desk reference.
Also there is a 30-page appendix covering the OSI model, which is great for other exams as well. The book has a cd-rom with over 200 practice questions as a companion for test taking. Overall the book exceeded my every expectation and is surely one for the technical library.
