A network administrator is configuring a WLAN. Why would the administrator use a WLAN controller?
- to centralize management of multiple WLANs
- to provide privacy and integrity to wireless traffic by using encryption
- to facilitate group configuration and management of multiple WLANs through a WLC
- to provide prioritized service for time-sensitive applications
Explanation: A WLAN Controller (WLC) is used to centrally manage and automatically configure multiple Lightweight Access Points (LAPs) and WLANs using the CAPWAP protocol. While autonomous APs require time-consuming manual configuration for each device, a WLC facilitates group configuration, allowing an administrator to manage many APs simultaneously as a single system, which is essential for scalability in large network environments.
