You are asked to apply the samesystem-level configurationacross all the devices in multiple sites usingMist 
AI.
According to Juniper Networks, which solution should you use in this scenario?
Use the CLI on each device.
Use the site-level switch configuration option in Mist AI.
Use an organization-level template in Mist AI.
Use the individual switch configuration option in Mist AI.
Answer: C
Explanation
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.

Question #:5 - [Monitoring and Troubleshooting]
Which campus fabric architecture supportsLayer 3 gateways at the distribution layer?
campus fabric core/distribution – centrally-routed bridging (CRB)
campus fabric IP Clos
campus fabric core/distribution – edge-routed bridging (ERB)
EVPN multihoming
Answer: C
Explanation
In Juniper’scampus fabric architectures, the location of theLayer 3 gateway(IRB) differentiates between CRB 
and ERB models:
Centrally-Routed Bridging (CRB):L3 gateways are placed at thecore layer.
Edge-Routed Bridging (ERB):L3 gateways are placed at thedistribution layer, closer to the edge.
“In the ERB model, Layer 2 gateways are deployed at the access layer, andLayer 3 gateways are deployed at 
the distribution layer.”
Option A (CRB):Incorrect — L3 is at the core, not distribution.
Option B (IP Clos):Incorrect — in 3-stage Clos, L3 is pushed to the access layer.
Option D (EVPN multihoming):Incorrect — this is about redundancy, not gateway placement.
Option C (ERB):Correct — L3 gateways sit at thedistribution layerin the ERB architecture.

Question #:6 - [Monitoring and Troubleshooting]
Which component performsVXLAN encapsulation and de-encapsulation?
VLAN
VTEP
root bridge
WXLAN policy
Answer: B
Explanation
In anEVPN-VXLANarchitecture, theVXLAN Tunnel Endpoint (VTEP)is responsible for encapsulating and 
de-encapsulating Layer 2 Ethernet frames into VXLAN packets that traverse the IP underlay.
“Each device participating in a VXLAN overlay operates as a VXLAN Tunnel Endpoint (VTEP). The VTEP 
encapsulates Ethernet frames into VXLAN headers for transmission and de-encapsulates VXLAN packets 
back into Ethernet frames upon receipt.”
Option A:Incorrect — VLAN is a Layer 2 construct, not responsible for encapsulation.
Option B:Correct— VTEP handles VXLAN encapsulationand de-encapsulation.
Option C:Incorrect — root bridge pertains to STP, not VXLAN.
Option D:Incorrect — WXLAN policy is not a valid networking term in Juniper documentation.

You must move from acampus fabric core-distribution centrally-routed bridging (CRB)network to anedge-
routed bridging (ERB)network.
In this scenario, where does thegateway for the networkmove?
from access to distribution
from distribution to core
from distribution to access
from core to distribution
Answer: C
Explanation
In Juniper Mist campus fabric architectures, thelocation of the Layer 3 gateway (IRB interface)
differentiatescentrally-routed bridging (CRB)fromedge-routed bridging (ERB):
InCRB, thegateway resides at the core layer— routing occurs centrally, and access/distribution layers perform 
Layer 2 bridging.
InERB, thegateway moves to the edge (distribution layer), enabling routing to occur closer to endpoints, 
improving performance and scalability.
“In a centrally-routed bridging (CRB) topology, Layer 3 gateways reside at the core. When transitioning to an 
edge-routed bridging (ERB) design, the Layer 3 gateways are moved to the distribution layer, closer to the 
access switches and clients.”
Therefore, when moving from acore-distribution CRBto anERBmodel, thegateway moves from the 
distribution to the access layerin campus terms (edge = access).
Option A:Incorrect — ERB gateways are not at the distribution layer only.
Option B:Incorrect — opposite direction.
Option C:Correct— the gateway movesfrom distribution to access (edge).
Option D:Incorrect — this describes CRB, not ERB.

Question #:8 - [Monitoring and Troubleshooting]
What are thetwo ways to forward BUM trafficwhen usingEVPN?(Choose two.)
Use static routes.
Use BGP neighborship.
Use ingress replication.
Use underlay replication.
Answer: C D
Explanation
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.

The control plane learns the MAC addresses of end-user devices.
The control plane learns the IP addresses of end-user devices.
The control plane rewrites the destination MAC address of the packet.
Answer: B C
Explanation
In anEVPN-VXLAN fabric, thecontrol planeoperates overBGP EVPNand is responsible for distributing 
endpoint reachability information (MAC and IP) among VTEPs. Thedata plane, by contrast, performs 
encapsulation and forwarding.
“The EVPN control plane uses BGP to exchange MAC and IP address reachability information between 
VTEPs, enabling efficient forwarding and loop prevention without relying on flood-and-learn behavior.”
Option A:Incorrect — encapsulation occurs in thedata plane, not the control plane.
Option B:Correct — the control plane distributesMAC-to-VTEP mappings.
Option C:Correct — the control plane also distributesIP-to-MAC associations(Type 2 and Type 5 EVPN 
routes).
Option D:Incorrect — the control plane does not alter packet headers.

Answer: A
Juniper - JN0-460Pass Exam
9 of 9Verified Solution - 100% Result
Explanation
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.
