The Cisco CCNA certification requires that you learn and master a number of skills. As you study this book, incorporating Boson NetSim^® into your learning process will help you successfully complete the CCNA certification by passing the ICND2 exam. The Boson NetSim Limited Edition (LE) included with this book will get you started on your way, and additional capability from the full edition is available after purchasing an upgrade.

The Boson NetSim Network Simulator^® is an application that will help you with the practical, hands-on portion of your education. NetSim will ensure that you understand the concepts of routing and switching by challenging you to apply those concepts on Cisco devices. Once you feel that you have mastered both the theory and the practical labs, you can test your knowledge using the exams included with this book and the accompanying digital resources. You may also purchase ExSim-Max^™ practice exams from Boson, available at www.boson.com. ExSim-Max practice exams are designed to simulate the complete exam experience, including topics covered, question types, question difficulty, and time allowed. With ExSim-Max, you can be sure you are ready to pass the real exam—guaranteed (www.boson.com/guarantee).

Boson NetSim provides more versatility and support than any other network simulation software on the market. Boson NetSim will not only help you become CCNA certified, it will actually help you learn and understand how to configure routers, switches, and networks.
