What is the role of a RADIUS server in a captive portal deployment?

To host the captive portal login page

To assign IP addresses to clients

To authenticate users and provide accounting information

To encrypt traffic between the client and the access point

A coffee shop wants to customize its captive portal page with a logo and a custom success message. After uploading the logo and editing the HTML, customers still see the default Juniper page. What is the most likely reason?

The customers' browsers are caching the old page.

The logo file is too large and the portal cannot display it.

The custom page was not saved and activated in the captive portal configuration.

The captive portal is using RADIUS authentication, which does not support custom pages.

In a Layer 2 access control scenario, which type of traffic is typically intercepted by a captive portal?

Only traffic destined to the internet

HTTP and HTTPS traffic from unauthenticated clients

All IP traffic from unauthenticated clients

Which configuration element is required on a Juniper device to enable a captive portal on a specific interface?

A DHCP server configuration on that interface

A RADIUS server configuration on that interface

A firewall filter that redirects HTTP traffic to the captive portal

A captive portal profile and a service interface

A university uses a captive portal on its campus Wi-Fi. Students complain that they cannot connect to network printers that use mDNS (Bonjour) for discovery. The printers are on the same VLAN as the students. The captive portal is intercepting all traffic except DHCP and DNS. What should you do to allow printer discovery while still requiring authentication?

Disable the captive portal on the printer VLAN.

Add an exemption for mDNS traffic (UDP 5353) in the captive portal redirect rules.

Move the printers to a different VLAN and configure inter-VLAN routing.

Configure the captive portal to redirect all UDP traffic to the login page.

Captive Portal JN0-650 Practice Questions (Page 3)

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.
