A Junos switch is configured with 802.1X as the primary method and MAC RADIUS as a fallback. A user reports that their device is not getting network access. The administrator checks the logs and sees that the device is sending 802.1X EAPOL frames, but the authentication is not completing. Which log or debug command would help the administrator determine why the 802.1X authentication is failing?

show log messages | match dot1x

show dot1x interface ge-0/0/1 detail

When does Junos OS consider a primary authentication method to be 'not applicable' and trigger fallback?

When the RADIUS server returns an Access-Reject

When the client does not respond to the method's initiation (e.g., no 802.1X EAPOL frames)

When the client's MAC address is not in the local database

When the interface is administratively down

Which scenario is the primary reason for configuring multiple authentication methods on a Layer 2 access interface?

To provide redundancy in case the primary authentication server fails

To increase the security of the authentication process by requiring two-factor authentication

To allow different client types to authenticate using the method they support

To reduce the load on the RADIUS server by distributing authentication requests across multiple servers
