When configuring fallback to local authentication, what must be present on the switch for the fallback to work?

A captive portal configured on the interface

A configured RADIUS server with a valid secret

Local user accounts with passwords configured

An LDAP server reachable from the switch

What is the primary purpose of server fail fallback in Layer 2 authentication and access control?

To load-balance authentication requests across multiple RADIUS servers

To automatically update RADIUS server configurations without manual intervention

To provide an alternative authentication method when the primary RADIUS server is unavailable

To increase the security of the network by requiring multiple authentication methods

Which statement best describes the behavior of server fail fallback?

It is automatically disabled when the RADIUS server becomes reachable again

It is triggered only when the RADIUS server returns an Access-Reject message

It is used to switch between different RADIUS servers in a round-robin fashion

It is triggered when the RADIUS server is unreachable or times out, and it applies a predefined fallback action

How does server fail fallback apply to 802.1X authentication?

It requires a separate fallback configuration for 802.1X

It uses the same fallback actions as other access types, such as local authentication or deny access

It only applies to the initial authentication, not reauthentication

Which condition triggers server fail fallback?

The user enters incorrect credentials

The RADIUS server returns an Access-Reject message

The RADIUS server is unreachable or times out
