IEEE 802.1x is a standard that provides port-based authentication, which blocks all traffic on a port-by-port basis until the client is authenticated using credentials stored on an authentication server. This standard provides a greater degree of security compared to other options listed. LDAPS and TACACS are authentication protocols, but do not implement port-based authentication. IEEE 802.1a is a wireless networking standard and is not related to authentication or security.
