CCNA 2: Fundamentals of routing, switching and wireless networks

This module covers the architecture, components and operation of routers and switches in networks. Participants learn how to virtually segment VLANs, how to route between them and basic switch security settings. They learn about WLAN concepts and how to set them up. Learn the basic principles of routing and how to set up static and default routes in IP networks. They know how to protect a company’s LAN.
