CCNA: Switching, Routing, and Wireless Essentials

The middle course of the series

This is the second course in the CCNA series, focused on switching, routing and wireless. It builds on the networking fundamentals of the first course and moves toward the practical skills that associate-level roles call for.

Wireless and the local network

The listing highlights WLANs, which are explored alongside switching and routing rather than as a separate topic. Learning how the local network and wireless layer fit together is the main step forward here.

Approach

• Take the course after the introduction so the switching concepts have context.
• Practise configuring switches and access points on a simulator where you can.
• Note how wireless troubleshooting connects back to the routing and switching basics.

The named job roles, including network administrator and network engineer, give a clear picture of where these skills lead.
