CCNA: Cisco Certified Network Associate: Fast Pass by Todd Lammle

Book Preface

How Is This Book Organized?

This book is organized according to the official objectives list prepared by Cisco for the CCNA exam. The chapters correspond with the eight broad categories:

• Describe how a network works.
• Configure, verify and troubleshoot a switch with VLANs and interswitch communications.
• Implement an IP addressing scheme and IP Services to meet network requirements in a medium-size Enterprise branch office network.
• Configure, verify, and troubleshoot basic router operation and routing on Cisco devices.
• Explain and select the appropriate administrative tasks required for a WLAN.
• Identify security threats to a network and describe general methods to mitigate those threats.
• Implement, verify, and troubleshoot NAT and ACLs in a medium-size Enterprise branch office network.
• Implement and verify WAN links.

Within each chapter, the individual exam objectives are each addressed. Each section of a chapter covers one exam objective. For each objective, the critical information for that exam objective is first presented, and then there are several Exam Essentials for each exam objective.
Additionally, each chapter ends with a section of Review Questions. Here is a closer look at each of these components:

Exam Objective The individual exam objective sections present the greatest level of detail on information that is relevant to the CCNA exam. This is the place to start if you’re unfamiliar with or uncertain about the technical issues related to the objective.

Exam Essentials Here you are given a short list of topics that you should explore fully before taking the test. Included in the Exam Essentials areas are notations of the key information you should take out of the exam objective section.
