Description

This is a Free CCNA 200-301 Course that covers the OSI and TCP/IP models. This course covers knowledge that you need for the CCNA exam, but also for the CompTIA Network+ exam. Learn the fundamentals and basics of networking.

Why do you need to learn the TCP/IP and OSI models? Are they important to know? Yes - you need to know these models for both the CCNA exam, but also for the real world.

People in the real world argue about this, but models like the OSI and TCP/IP help with both understanding and network troubleshooting. Make sure you learn especially the TCP/IP model for the CCNA exam.

The Cisco Certified Network Associate (CCNA) is highly recommended as your first certification if you want to become a network engineer. To become a CCNA, you need to pass the CCNA 200-301 exam.

Start with your CCNA exam and then look at furthering your career by becoming a CCNP (Cisco Certified Network Professional) or DevNet Associate.

If you continue with your studies, you could one day become a Cisco Certified Network Expert (CCIE) - one of most highly regarded certifications in the networking industry.
