A network administrator is configuring 802.1X on a switch port that connects to a device that does not support 802.1X. The administrator wants to allow the device to access the network but also wants to ensure that if the device is replaced with a different device, the port will not automatically grant access. Which configuration should be used?

Enable MAB and configure the RADIUS server to authenticate the MAC address.

Configure the port as an access port in the default VLAN.

Use a static MAC address entry in the switch's forwarding table.

What is the primary purpose of 802.1X in a network?

To provide a secure tunnel for remote access

To encrypt all data traffic between the client and the switch

To filter traffic based on MAC addresses

To prevent unauthorized devices from gaining access to the network at the port level

What is RADIUS-initiated disconnect (CoA) used for in 802.1X?

To terminate an authenticated session from the RADIUS server

To update the switch's firmware

To initiate a new authentication session

To change the client's IP address

What is the first step in the 802.1X authentication process when a client connects to a switch port?

The switch sends a RADIUS Access-Request to the authentication server

The client sends an EAPOL-Start message to the switch

The client sends an EAP-Response/Identity message to the switch

The switch sends an EAP-Request/Identity message to the client
