A switch port is configured with 802.1X and a user's device is connected. The port is in the authorized state. The user's session is active, but the administrator wants to manually terminate the session. What action should the administrator take?

Send a RADIUS Disconnect-Request to the switch.

Disable the port and re-enable it.

Clear the 802.1X configuration on the port.

Wait for the reauthentication timer to expire.

A network administrator is configuring 802.1X on a Juniper switch and wants to understand the flow of authentication messages. A user's device connects to a port, and the switch sends an EAPOL-Request/Identity. The supplicant responds with an EAPOL-Response/Identity. What is the next message that the switch sends?

A RADIUS Access-Request containing the EAP-Response/Identity to the authentication server.

An EAPOL-Success frame to the supplicant to indicate successful identity validation.

An EAPOL-Request/Challenge to the supplicant to verify the password.

A RADIUS Access-Challenge to the supplicant to request additional credentials.

A network administrator is configuring reauthentication on a Juniper switch for 802.1X. The requirement is that users must reauthenticate every 30 minutes. The administrator sets the reauthentication timer to 1800 seconds. What happens when the timer expires?

The port remains authorized and the timer resets without any action.

The port immediately transitions to the unauthorized state and the user must reauthenticate from scratch.

The switch sends a RADIUS Access-Request directly to the server without involving the supplicant.

The switch sends an EAPOL-Request/Identity to the supplicant to begin a new authentication exchange.

A network administrator is configuring 802.1X on a Juniper switch and wants to ensure that when a user logs off, the port transitions to the unauthorized state immediately. What must be configured to achieve this?

The reauthentication timer must be set to a low value.

The RADIUS server must send a Disconnect-Request to the switch.

The supplicant must send an EAPOL-Logoff frame to the switch.

The switch must be configured to detect link loss and transition the port to unauthorized.
