Refer to the exhibit. Company A wants to use a RADIUS server to service all user and device authentication attempts with a more secure and granular authentication approach. Not all client devices supp

AutoConfig IPSK is a feature for managing pre-shared keys for devices without 802.1X, but it is not the primary configuration for a comprehensive RADIUS-based enterprise authentication solution for all users and devices.

To use a RADIUS server for authentication, it must be explicitly configured and selected under the AAA servers tab, linking the wireless network to the external authentication service for centralized user and device validation.

Configuring 'Enterprise Security type' (e.g., WPA2/WPA3 Enterprise) under the Layer 2 tab is necessary to enable 802.1X authentication, which leverages a RADIUS server for centralized, secure, and granular user and device authentication, while also allowing for other RADIUS-backed methods like MAC Authentication Bypass for non-dot1x clients.

Setting authentication under the Layer 3 tab typically refers to post-association web authentication or guest access, not the fundamental Layer 2 authentication for connecting to the wireless network using a RADIUS server.

Enabling a generic WPA2 policy is insufficient as it does not specify the WPA2-Enterprise mode necessary for integration with a RADIUS server for centralized authentication.
