Which three types of traffic are allowed by IEEE 802.1X access control prior to getting
authenticated? (Choose three.)
Until the client is authenticated, IEEE 802.1x access control allows only Extensible Authentication
Protocol over LAN (EAPOL), Cisco Discovery Protocol (CDP), and Spanning Tree Protocol (STP)
traffic through the port to which the client is connected. After authentication, normal traffic passes
through the port.
