A company requires the use of 802.1X security. What type of traffic can be sent if the authentication port-control auto command is configured, but the client has not yet been authenticated?

  • SNMP
  • EAPOL
  • broadcasts such as ARP
  • any data encrypted with 3DES or AES

Explanation: 802.1X prevents unauthorized devices from gaining access to the network. The authentication port-control auto command turns on 802.1X access control. Until the client is authenticated, 802.1X only allows Extensible Authentication Protocol over LAN (EAPOL), Cisco Discovery Protocol (CDP), and Spanning Tree Protocol (STP) traffic to pass through the port. EAPOL messages are sent between the client and the authenticator such as a switch. If authentication is successful, normal traffic can be sent and received through the port.
