Authorized Self-Study Guide: Building Cisco Multilayer Switched Networks (BCMSN), Fourth Edition, is a Cisco® authorized, self-paced learning tool for CCNP® switching foundation learning. You will learn how to create scalable multilayer switched networks by installing, configuring, monitoring, and troubleshooting network infrastructure equipment for a campus switched network and integrate advanced technologies such as VoIP and wireless.
This comprehensive book provides detailed information and easy-to-grasp tutorials on advanced skills in design, configuration, operation, and troubleshooting of enterprise level switched networks, including converged IP data, voice, and Airespace wireless LAN (WLAN) connectivity. The book assumes only a basic understanding of networking so it provides a great deal of detail on the topics covered.
This book is ideal for certification candidates who are seeking a self-paced tool to learn the material covered in the latest BCMSN exam.
Each chapter opens with the list of topics covered to clearly identify the focus of that chapter. At the end of each chapter, Study Tips list the main points related to the BCMSN exam. A summary of key concepts for quick study and review questions provide you with an opportunity to assess and reinforce your understanding of the material. Real-world case studies help illuminate theoretical concepts.
In addition, chapters that cover Catalyst configurations also include configuration exercises. Most of these are small-scale exercises that can be performed on a single switch. The goal of using small-scale exercises is to enable network professionals to practice the configuration exercises with only a single switch.
