Juniper JN0-460 Exam Dumps

In Mist,sitesrepresent the physical or logical grouping of devices within an organization.

You create and manage a site configuration under theLocationhierarchy in the Mist UI.

Each site inherits organization-level settings but can override or customize specific configurations such as VLANs, templates, or switch settings.

Group-Based Policy (GBP)is a Juniper EVPN-VXLAN feature that enablesmicrosegmentationwithout requiring multiple VRFs or VLANs. It is implemented within Juniper Mist'sWired Assurance and Campus Fabricframeworks.

''GBP provides scalable, identity-based segmentation for campus fabrics and is supported on EX4100 and EX4400 Series switches operating in EVPN-VXLAN mode under Mist management.''

The feature requires hardware and software support forEVPN-VXLAN and GBP tagging, which is currently available on specific EX models managed by Mist Cloud.

Option A:Correct--- GBP requires compatible access switches, specifically EX4100 and EX4400 models.

Option B:Incorrect --- GBP is centrally managed through Mist Cloud, not configured per switch.

Option C:Incorrect --- GBP is provisioned via Mist Cloud, not the CLI.

Option D:Incorrect --- GBP is not supported onallEVPN-capable switches; only on defined platforms (EX4100/EX4400).

InMist Cloud,site variablesare used to store and reference common configuration values (such as VLAN IDs, subnet addresses, or gateway IPs) that are reused across multiple devices and templates within a site.

''Site variables allow administrators to define reusable configuration parameters that can be referenced in multiple templates or device configurations, ensuring consistency and reducing manual errors.''

Option A:Incorrect --- applies configuration directly, not reusable references.

Option B:Correct--- site variables enable you to reference the same VLAN or value in multiple configurations (switches, WLANs, etc.).

Option C:Incorrect --- WLAN templates are for wireless SSID configuration.

Option D:Incorrect --- switch templates define static configuration but don't store shared variables.

Anorganization-level configuration templatecan only be applied tosite groups, not to individual sites.

Therefore, a single site such as Site A cannot be directly specified inside an org-level template.

Mist Cloud Configuration Hierarchy Overview

===========

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.
