Understanding Cisco Wireless Foundations [WLFNDU]

OVERVIEW

The Understanding Cisco Wireless Foundations (WLFNDU) course provides the knowledge and skills needed to configure, manage, and troubleshoot a Cisco wireless LAN (WLAN) network. Topics include understanding critical aspects of RF technology, industry standards for Wi-Fi and security, how to design, install, and configure a WLAN network of any size, as well as using Cisco DNA Center.

Completing this course will enable you to implement a WLAN network for your organization and give you the foundational knowledge necessary to prepare for the Designing Cisco Enterprise Wireless Networks (ENWLSD) and Implementing Cisco Enterprise Wireless Networks (ENWLSI) courses.

This course is worth 30 Continuing Education (CE) credits towards recertification
