Free Practice Questions for Juniper JN0-460 Exam

According toJuniper Mist Wired Assurance documentation, three built-in diagnostic tools available for testing switch functionality areBounce Port,Ping, andCable Test.

Bounce Portallows you to disable and re-enable a port to reset connectivity.

Pingverifies Layer 3 reachability between the switch and target IPs.

Cable Testperforms diagnostics to detect wiring faults, impedance mismatches, or cable lengths.

These tools are accessed directly from theSwitch Testing Toolssection in the Mist dashboard and are available for EX Series and QFX Series switches onboarded to the Mist cloud.

InEVPN-VXLAN,BUM (Broadcast, Unknown unicast, and Multicast)traffic is handled differently than unicast traffic. EVPN provides two main forwarding mechanisms to distribute BUM traffic betweenVTEPs(VXLAN Tunnel Endpoints):

“BUM traffic in EVPN-VXLAN fabrics is replicated using eitheringress replicationorunderlay multicast(PIM-based). Both methods ensure that broadcast and unknown unicast frames reach all remote VTEPs within the same VXLAN segment.”

Option A:Incorrect — static routes are unrelated to BUM forwarding.

Option B:Incorrect — BGP is thecontrol plane, not a data-plane forwarding method.

Option C:Correct—Ingress replicationreplicates BUM packets to all remote VTEPs in the same VNI using unicast tunnels.

Option D:Correct—Underlay replication (multicast)uses multicast groups in the IP underlay to distribute BUM frames efficiently.

Juniper Mist supports ahierarchical configuration model:

Organization level:global configuration templates applied across sites.

Site level:shared configuration for all devices in a site.

Individual device level:unique overrides.

To applycommon system-level settings(e.g., NTP, SNMP, DNS, syslog) across multiple sites, the correct method is to use anorganization-level template.

“Organization-level templates provide a consistent configuration framework that can be applied across multiple sites, ensuring uniform system settings for all switches.”

Option A:Incorrect — manual CLI configuration defeats automation.

Option B:Incorrect — applies only to one site, not multiple.

Option C:Correct— organization-level templates provide centralized configuration for all sites.

Option D:Incorrect — individual configuration is for unique settings only.

In Juniper Mist, thesyslogfeature allows administrators to forward event messages and alerts from the Mist cloud to an external syslog server.

This is often used for centralized event monitoring, compliance, and correlation with tools like Splunk or SIEM systems.

Syslog operates over UDP or TCP and can capture switch events, system logs, and Marvis actions for both Wired and Wireless networks.

Route targets (RTs)are extended BGP communities used inMultiprotocol BGP (MP-BGP)forEVPN-VXLANto control route import/export between VRFs.

“A route target identifies the VRF instances that should import or export specific MP-BGP routes. It enables the association of EVPN routes with particular VRFs in multi-tenant environments.”

Option A:Incorrect — EVPN family support is identified through BGP capabilities, not RTs.

Option B:Incorrect — that’s handled by BGP EVPN negotiation, not route targets.

Option C:Correct— route targets definewhich VRFs import/export BGP routes.

Option D:Incorrect — RTs can be manually configured and reused where necessary.
