Which Junos OS configuration hierarchy is used to configure server fail fallback?

set interfaces unit 0 family ethernet-switching

Which authentication method is commonly used as a fallback when the primary RADIUS server is unreachable?

RADIUS authentication using a secondary server

Local authentication using credentials stored on the switch

A user reports that they are unable to authenticate via 802.1X. The network administrator checks the switch and sees that the RADIUS server is reachable, but the user's authentication is still failing. Which show command should the administrator use to diagnose the issue?

show interfaces ge-0/0/1 extensive

show configuration access profile employee

show dot1x interface ge-0/0/1 detail

A user's laptop was authenticated via local authentication fallback because the RADIUS server was unreachable. The RADIUS server has since recovered. When will the switch revert to using RADIUS for this user's session?

At the next reauthentication interval

Immediately when the RADIUS server becomes reachable

The switch never reverts to RADIUS for this session

Only when the user disconnects and reconnects

Which scenario would most likely use fallback to allow access?

A network that requires all users to authenticate via captive portal

A network that uses only local authentication

A network where maintaining connectivity is more important than strict authentication

A network where security is the highest priority

Server Fail Fallback JN0-650 Practice Questions (Page 1)

Part of the Layer 2 Authentication and Access Control domain, which makes up ~19% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–11 in this domain), expect 1–2 from this objective — we provide 29 practice questions to prepare you well beyond it.
