On a WLC, which selections are required when configuring a RADIUS server for wireless authentication?

The correct answer is AAA Override and the IP address of the server. When configuring a RADIUS server on a Wireless LAN Controller (WLC) for wireless authentication, the WLC needs to know the IP address of the RADIUS server to send authentication requests to. AAA Override is also a crucial setting. It allows the WLC to apply specific authentication, authorization, and accounting (AAA) parameters received from the RADIUS server, such as dynamic VLAN assignments or access control lists (ACLs), on a per-user basis. Client Exclusion and SSH are incorrect. Client Exclusion is a security feature that temporarily blocks clients after failed authentication attempts, not a core RADIUS configuration. SSH is a secure management protocol for accessing the WLC, not directly related to RADIUS server setup. Network Access Control State and SSH are incorrect. Network Access Control State refers to the overall NAC policy, not a specific RADIUS server configuration parameter. 802.1x and the MAC address of the server are incorrect. 802.1x is the authentication standard used with RADIUS, but it's an overarching protocol, not a specific WLC configuration field for the RADIUS server itself. The WLC uses the IP address, not the MAC address, to communicate with the RADIUS server.
