Juniper Mist AI Wired, Specialist JN0-460 JNCIS-MistAI-Wired Exam Questions

Answer : B, D

During campus fabric deployment in Mist AI, switches are onboarded using claim codes and must be assigned to the correct site and online so that Mist can push configurations and validate connectivity.

''All switches to be included in a campus fabric must be claimed, online, and assigned to the target site before launching the Campus Fabric wizard. Mist Cloud automatically discovers their roles and builds the topology.''

Option A: Incorrect --- switches must be site-assigned before fabric creation.

Option B: Correct --- switches must be online to receive configurations from Mist.

Option C: Incorrect --- offline devices cannot be configured or validated in the fabric wizard.

Option D: Correct --- switches must be assigned to the correct site for topology creation.

Answer : B, C

In an EVPN-VXLAN fabric, the control plane operates over BGP EVPN and is responsible for distributing endpoint reachability information (MAC and IP) among VTEPs. The data 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 the data plane, not the control plane.

Option B: Correct --- the control plane distributes MAC-to-VTEP mappings.

Option C: Correct --- the control plane also distributes IP-to-MAC associations (Type 2 and Type 5 EVPN routes).

Option D: Incorrect --- the control plane does not alter packet headers.

Answer : C

Juniper Mist supports a hierarchical 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 apply common system-level settings (e.g., NTP, SNMP, DNS, syslog) across multiple sites, the correct method is to use an organization-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.

Answer : D

When Marvis Actions display ''AI Validated,'' it indicates the issue was detected earlier but is now resolved.

Marvis automatically validates remediation and marks the action closed once the anomaly clears.

Answer : C

In Juniper Mist campus fabric architectures, the location of the Layer 3 gateway (IRB interface) differentiates centrally-routed bridging (CRB) from edge-routed bridging (ERB):

In CRB, the gateway resides at the core layer --- routing occurs centrally, and access/distribution layers perform Layer 2 bridging.

In ERB, the gateway 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 a core-distribution CRB to an ERB model, the gateway moves from the distribution to the access layer in 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 moves from distribution to access (edge).

Option D: Incorrect --- this describes CRB, not ERB.

Answer : D

When a switch is successfully onboarded into Mist Cloud but shows ''Unassigned,'' it means the device has been claimed into the organization but has not yet been assigned to a specific site.

''After claiming switches into an organization, you must assign each switch to a site for it to transition from Unassigned to Connected state and begin receiving configuration and telemetry updates.''

Option A: Incorrect --- rescanning is not needed once the device is claimed.

Option B: Incorrect --- reboots are unnecessary for assignment recognition.

Option C: Incorrect --- these commands are for connectivity troubleshooting, not site assignment.

Option D: Correct --- assigning each switch to its intended site enables full Mist management and connectivity state.

Answer : A

Syslog is the standard method for exporting Mist AI event and telemetry messages to third-party collectors.

It supports both UDP and TCP delivery for centralized log correlation.
