Introduction

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, switching, voice and security, and now data center technology! The Cisco certifications reach beyond the popular certifications, such as those from CompTIA and Microsoft, to provide you with an indispensable factor in understanding today’s network—insight into the Cisco world of internetworking and beyond. 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, and now the best at configuring and administering Nexus and data center technologies. This book will lead you in that direction.
