Overview

Introduction to Networks v6 Labs & Study Guide / Edition 1

The only authorized Labs & Study Guide for the Cisco Networking Academy Introduction to Networks course in the CCNA Routing and Switching curriculum

Each chapter of this book is divided into a Study Guide section followed by a Lab section.

The Study Guide section offers exercises that help you learn the concepts, configurations, and troubleshooting skills crucial to your success as a CCENT exam candidate. Each chapter is slightly different and includes some or all the following types of exercises:

• Vocabulary Matching Exercises

• Concept Questions Exercises

• Skill-Building Activities and Scenarios

• Configuration Scenarios

• Packet Tracer Exercises

• Troubleshooting Scenarios

The Labs & Activities include all the online course Labs and Packet Tracer activity instructions. If applicable, this section begins with a Command Reference that you will complete to highlight all the commands introduced in the chapter.
