A network administrator is configuring a WLAN. Why would the administrator use RADIUS servers on the network?
- to centralize management of multiple WLANs
- to restrict access to the WLAN by authorized, authenticated users only
- to facilitate group configuration and management of multiple WLANs through a WLC
- to monitor the operation of the wireless network
Explanation: A RADIUS server is required for Enterprise security mode to provide Authentication, Authorization, and Accounting (AAA) services. Unlike the Personal mode which uses a single pre-shared key, RADIUS requires users to provide their own unique username and password. This allows the administrator to restrict access to authorized users only, centrally manage user accounts, and maintain a detailed audit trail of individual network activity.
