Explanation

WPA2-Enterprise (also called WPA2 with 802.1X) uses a RADIUS (Remote Authentication Dial-In User Service) server as its authentication backend. When a wireless client attempts to connect, the access point acts as an authenticator and forwards the client's credentials to the RADIUS server, which verifies them against a user directory and grants or denies access. This provides individualized authentication per user rather than a shared passphrase. TACACS+ (A) is a network device administration protocol used to control access to routers and switches, not typically used for wireless client authentication. LDAP (B) is a directory query protocol; while RADIUS may consult an LDAP directory internally, LDAP itself is not the 802.1X authentication protocol. MDM (D) is Mobile Device Management, used for managing and enforcing policies on devices, not for wireless authentication.
