My advice: Don't get caught up in the debates. Learn what is important for the CCNA exam which is the TCP/IP model. Know your protocols, but don't get too concerned about where everything fits. Nothing in life is simple.

This is video #8 of my FREE CCNA Course 200-301 - a complete CCNA course for the new Cisco CCNA exam. I am going to be covering all the topics in the exam blueprint in this course. 

I want to make this content practical and it will include a lots of labs and demonstrations to help you better understand topics on the exam.

The course will contain:
- Videos
- Labs using Cisco Packet Tracer
- Quiz Questions
- And more!
