CCENT Practice and Study Guide is designed with dozens of exercises to help you learn the concepts and configurations crucial to your success with the Interconnecting Cisco Networking Devices Part 1 (ICND1 100-101) exam. 

The author has mapped the chapters of this book to the first two Cisco Networking Academy courses in the CCNA Routing and Switching curricula, Introduction to Networks and Routing and Switching Essentials. These courses cover the objectives of the Cisco Certified Networking Entry Technician (CCENT) certification. Getting your CCENT certification means that you have the knowledge and skills required to successfully install, operate, and troubleshoot a small branch office network. 

As a Cisco Networking Academy student or someone taking CCENT-related classes from professional training organizations, or college- and university-level networking courses, you will gain a detailed understanding of routing by successfully completing all the exercises in this book.

Each chapter is designed with a variety of exercises, activities, and scenarios to help you: 

·  Review vocabulary

·  Strengthen troubleshooting skills 

·  Boost configuration skills

·  Reinforce concepts

·  Research and analyze topics
