This revised and expanded edition, which has 1:1 chapter-to-online module alignment, contains many learning aids that have been redesigned to help you reinforce the material in the course, focus on important concepts, and organize your study time for exams.

Chapter Objectives are stated as questions at the beginning of each chapter. The objectives cover only the topics that are critical to passing the certification exam. The question format encourages you to think about finding the answers as you read through the chapter's content.
Additional Topics of Interest is a new feature that indicates related information provided in the chapter that is not pertinent to pass the certification exam but would certainly be worthy to know on the job.
Key Terms are now also listed at the beginning of each chapter in order of occurrence to alert you to the technical vocabulary that you need to understand as you work through that chapter. Key terms are then highlighted at first reference and defined at the end of the corresponding chapter. At the back of this book, an extensive Glossary collects all the key terms and their definitions.
Check Your Understanding questions with an answer key help you keep track of your progress and aid studying for the assessments.

Cisco Networking Academy Program CCNA 1 and 2 Companion Guide, Revised Third Edition, is the Cisco approved textbook to use alongside version 3.1 of the Cisco Networking Academy Program CCNA 1 and CCNA 2 web-based courses. The topics covered provide you with the necessary knowledge to begin your preparation for the CCNA certification exam (640-801, or 640-821 and 640-811) and to enter the field of network administration.

As in the courses, the CCNA 1 section covers networking basics, including the basics of Ethernet technologies, TCP/IP, network media, IP addressing, and routing. The CCNA 2 section covers routers and routing basics, including the basics of configuring routers, routing protocols, more TCP/IP concepts, access control lists, and networking troubleshooting skills.

Informaci�n sobre el derecho de desistimiento

Derecho legal de desistimiento

Tiene derecho a rescindir este contrato en un plazo de 14 d�as sin dar ning�n motivo.

El periodo de desistimiento vencer� a los 14 d�as desde que usted, o un tercero que no sea el transportista e indicado por usted, adquiera la posesi�n f�sica del �ltimo bien o del �ltimo lote o pieza.

Para ejercer el derecho de desistimiento, complete de forma electr�nica y env�e una declaraci�n clara en nuestro sitio web, desde "Mis compras" en "Mi cuenta". Le enviaremos sin demora un acuse de recibo de dicho desistimiento a trav�s de un soporte duradero (por ejemplo, por correo electr�nico).

Para cumplir con el plazo de desistimiento, basta con que env�e su comunicaci�n relativa al ejercicio del derecho de desistimiento antes de que venza el periodo de desistimiento.

Efectos del desistimiento

Si rescinde este contrato, le reembolsaremos todos los pagos que hayamos recibido de usted, incluidos los gastos de env�o (excepto los gastos adicionales que surjan si elige un tipo de env�o que no sea el tipo de env�o est�ndar m�s econ�mico que ofrecemos).

Podemos hacer una deducci�n del reembolso por la p�rdida de valor de cualquier bien suministrado, si la p�rdida es el resultado de una manipulaci�n innecesaria por su parte.

Efectuaremos el reembolso sin demoras indebidas y, a m�s tardar, 14 d�as despu�s de que se nos informe de su decisi�n de rescindir este contrato.

Efectuaremos el reembolso utilizando el mismo medio de pago que utiliz� para la transacci�n inicial, a menos que haya acordado expresamente lo contrario; en cualquier caso, no incurrir� en ning�n cargo como resultado de dicho reembolso.

Podremos retener el reembolso hasta que hayamos recibido los bienes o hasta que nos haya presentado una prueba de que los ha devuelto, lo que ocurra primero.
