CCNA Routing and Switching ICND2 200-105 Official Cert Guide
All these previously mentioned options cost some money, but the next two are generally
free to the user, but with a different catch for each. First, GNS3 works somewhat like VIRL,
creating a virtual environment running real Cisco IOS. However, GNS3 is not a Cisco product,
and cannot provide you with the IOS images for legal reasons.
Cisco also makes a simulator that works very well as a learning tool: Cisco Packet Tracer.
However, Cisco intends Packet Tracer for use by people currently enrolled in Cisco
Networking Academy courses, and not for the general public. So, if you are part of a Cisco
Academy, definitely use Packet Tracer.
This book does not tell you what option to use, but you should plan on getting some handson
practice somehow. The important thing to know is that most people need to practice
using the Cisco CLI to be ready to pass these exams.
