The second course in the 3-part CCNA series — dive into switching technologies, VLANs, wireless networks, routing concepts, and LAN security for small-to-medium business environments.
CCNA: Switching, Routing, and Wireless Essentials focuses on switching technologies and router operations that support small-to-medium business networks, including wireless local area networks (WLANs) and security concepts. Students learn key switching and routing concepts, perform basic network configuration and troubleshooting, identify and mitigate LAN security threats, and configure and secure a basic WLAN. The course builds directly on the knowledge gained in CCNA: Introduction to Networks and prepares learners for the final course in the CCNA series.
