Excellent CCNA book!
on June 20, 2008
This book covers the WAN concepts that you will encounter on the CCNA Exam. It has chapters covering Basic WAN Concepts, PPP, Frame Relay, Network Security, ACLs, IPv6, NAT, DHCP, and Network Troubleshooting. The beginning of each chapter lists the exam objectives in the format of questions, and it also lists the key terms that you can look up in the glossary. I found this helpful because I could easily look up whatever term I was unfamiliar with before I started reading each chapter. I could also get an idea of what I was expected to learn from this chapter by reading the exam objectives. The diagrams in each chapter were explained in an easy to understand format, and that really helped me understand the concepts. The activities with each chapter helped me reviewcthe concepts that I learned in each chapter. There is also a "Check Your Understanding" and a "Challenging Questions" part at the end. These really tested me and helped me make sure I understood the concepts in each chapter. I was easily able to figure out what areas I needed to improve in. After going through this book I'm very confident of all the material I learned in it. I now have a clear understanding of WAN concepts, access lists, and network security. I highly recommend purchasing the CCNA Exploration Accessing the WAN Labs also for hands on experience.
