Cisco CCNA Wireless 200-355 WIFUND
Implementing Cisco Wireless Network Fundamentals
This Cisco video training course with Keith Barker covers the fundamentals of Wireless LANs (WLANs), including topics such as the integration of Access Points (APs), WLAN Controllers (WLCs), the implementation of WLAN security, and more.
This course will assist you in obtaining the knowledge and skills to understand and support Cisco WLANs. The skills learned also can be applied to other vendors’ WLANs as well, because there are basic concepts, techniques and standards involved, which apply to Wireless Networks, regardless of vendor.
This course includes recommendations to view Nuggets from other CBT Nuggets courses. While the course duration is listed as 7 hours, you should expect to spend approximately 28 hours training.
