What type of server is required for WPA/WPA2 Enterprise mode?

WPA/WPA2 Enterprise mode relies on a RADIUS server for authentication purposes. This server is essential as it manages user credentials and handles the authentication requests from the wireless access points. When a client attempts to connect to a Wi-Fi network utilizing WPA/WPA2 Enterprise, the access point forwards the request to the RADIUS server, which then verifies the user's credentials against a centralized database. This process allows for enhanced security through features such as 802.1X, which provides per-user authentication and supports various authentication methods.

While other types of servers like DHCP and TACACS can play roles in networking and authentication respectively, only the RADIUS server is specifically designed to work with WPA/WPA2 Enterprise for providing authentication services in this context. The DASH server is unrelated to this particular authentication process, focusing instead on device management. Thus, the RADIUS server is the correct type of server required for supporting WPA/WPA2 Enterprise mode in a secure Wi-Fi environment.
