CCNA INTRO: Introduction to Cisco Networking Technologies Study Guide: Exam 640-821, 9780470068502 (0470068507), Sybex, 2006

Welcome to the exciting world of Cisco certification! You have picked up this book because you want something better—namely, a better job with more satisfaction. Rest assured that you have made a good decision. Cisco certification can help you get your first networking job or more money and a promotion if you are already in the field.

Cisco certification can also improve your understanding of the internetworking of more than just Cisco products: You will develop a complete understanding of networking and how different network topologies work together to form a network. This is beneficial to every networking job and is the reason Cisco certification is in such high demand, even at companies with few Cisco devices.

Cisco is the king of routing and switching. The Cisco certifications reach beyond popular certifications such as the Microsoft Certified System Engineer (MCSE) and other operating system certifications to provide you with an indispensable factor in understanding today’s network insight into the Cisco world of internetworking. By deciding that you want to become Cisco certified, you are saying that you want to be the best—the best at routing and the best at switching. This book will lead you in that direction.

Initially, to secure the coveted Cisco certification, you took only one test and then you were faced with the (extremely difficult) Routing and Switching CCIE hands-on lab, an all-or-nothing approach that made it tough to succeed. In response to repeated failures from CCIE candidates, Cisco created a series of new certifications to help you get the coveted Cisco Certified Internetwork Expert (CCIE), as well as aid prospective employers in measuring skill levels even if you are not. With these new written certifications, which make for a better approach to preparing for that almighty lab, Cisco opened doors that few were allowed through before.
