Redes CISCO: Guía de estudio para la certificación CCNA 640-802
In an effort to ensure that network professionals possess the necessary knowledge to perform administration and support tasks, Cisco Systems has developed a series of courses and certifications that serve as a benchmark for network technologies. Certification examinations are designed to overcome the theoretical skills testing and configuration of devices in multiple hierarchies. Cisco certifications are highly valued by companies ranging from the associate level CCNA (Cisco Certified Network Associate), the professional level CCNP (Cisco Certified Network Professional) to the expert level CCIE (Cisco Certified Internetwork Expert).
This book represents a self-study tool for learning the issues related to the objectives of the certification exam CCNA 640-802. This book provides the concepts, commands and practices needed to configure Cisco routers and switches to work on corporate networks and to achieve this certification. Although this book was created for those pursuing the CCNA certification, it is also useful for administrators, support staff or those who simply wish to understand more clearly the operation of LAN, WAN, their protocols and access services
