JN0-460 Juniper JNCIS-MistAI-Wired Free Practice Exam Questions (2026 Updated)

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 encapsulation and 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.

InJuniper Mist Cloud, configuration hierarchy includesorganization-level templates,site-level configurations, andindividual switch configuration. Site and organization levels provide shared settings, while per-device details such as hostname or role are set individually.

“Device-specific attributes such as hostname, role, or management IP are configured under the individual switch configuration menu. Templates and site configurations apply globally, while individual configurations override device-level parameters.”

Option A:Incorrect — site configuration applies to all switches at a site, not unique details.

Option B:Incorrect — CLI configuration is not used when switches are managed by Mist Cloud.

Option C:Correct— each switch’s name and role are configured individually underSwitches → Switch Configuration.

Option D:Incorrect — organization templates define global settings, not per-switch names.

When a switch is claimed into a Mist organization, it appears in one of several states depending on connectivity and site assignment.

“After claiming, switches initially appear asUnassignedif they are not yet linked to a site. Once online and connected to Mist Cloud, they transition toConnectedstatus and begin receiving configurations and telemetry.”

Option A (Connected):Correct— indicates the switch is online and communicating with Mist Cloud.

Option B (Inactive):Incorrect — not a valid device state in Mist.

Option C (Active):Incorrect — “Active” is not a device state label in Mist.

Option D (Unassigned):Correct— indicates the switch has been claimed but not yet assigned to a site.

According to theJuniper Mist AI for Wired – Campus Fabric IP Clos Deployment Workflow, deploying a campus fabric involves a defined sequence of planning and configuration steps within the Mist Cloud interface. The key stages include:

“To deploy a campus fabric, you must first define the topology type, identify the physical connections between devices, and define the networks of interest that will be extended across the fabric.”

Breaking this down:

Choose the topology (D):Selecting the correct fabric type (3-Stage or 5-Stage IP Clos) determines how access, distribution, and core switches will interconnect.

Define the physical connections (A):This step involves specifying the uplink and downlink relationships between switches so that Mist can auto-generate EVPN-VXLAN and routing configurations.

Define the networks of interest (B):These are the VLANs and subnets that need to be extended across the fabric for user and device connectivity.

Steps such asconfiguring DNS serversordefining GBP tagsarenot part of the campus fabric deployment workflowin Mist Wired; they are optional or separate configurations outside the main deployment flow.
