What is the purpose of configuring fallback to captive portal when RADIUS servers fail?

To block all access until the RADIUS server is restored

To automatically assign users to a guest VLAN

To bypass authentication entirely

To allow users to authenticate using a web-based login page

A network administrator notices that the fallback to local authentication is triggering too frequently on a Junos OS switch. The RADIUS server is occasionally slow to respond, but it is not down. Which parameter should be adjusted to reduce the frequency of fallback triggers?

Change the fallback action to 'allow'

Increase the RADIUS timeout value

Decrease the RADIUS retry count

A company has a mixed network with 802.1X for employee laptops, MAC authentication for printers, and captive portal for guest Wi-Fi. The RADIUS server fails. Which statement correctly describes how server fail fallback applies to these different access types?

Captive portal fallback is only triggered if 802.1X fallback is also triggered.

The fallback action for 802.1X is always applied to all access types.

The fallback action is applied independently to each access type based on its configured profile.

MAC authentication bypasses fallback and always uses local authentication.

Which statement is true about server fail fallback for MAC authentication?

MAC authentication bypasses fallback because it does not use RADIUS

MAC authentication uses the same fallback actions as 802.1X

Fallback for MAC authentication is configured separately from other access types

MAC authentication does not support fallback to local authentication

Server Fail Fallback JN0-650 Practice Questions (Page 2)

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.
