CCNA INTRO Exam Certification Guide (CCNA Self-Study, 640-821, 640-801) Review by Always Reading
Good Overview of Cisco Basics
I read two Cisco preparation books prior to getting my hands on this one. Wendell Odom did a fantastic job of covering the basics of Cisco networking. If you plan on buying this book for the 640-801 exam, you should also consider his other book CCNA ICND (ISBN: 158720-083-X). Utilizing these two books really clarified any questions I had about Cisco switching and routing. This particular book is very basic and it describes much of the regular networking concepts in first few chapters. It then jumps into subnetting, VLANS and routing protocols. If you purchase the ICND book, these topics will be covered in much greater detail. Overall, the book is an excellent source in preparing for the CCNA exam.
