Frequently Asked Questions

Which topics carry the most weight on the JN0-460 exam?

Campus Fabric Architecture and Campus EVPN-VXLAN typically represent a larger portion of the exam because they require both conceptual understanding and design judgment. Wired Assurance Management or Operations also carries significant weight because operational troubleshooting is central to the Specialist role. Balance your study time accordingly, but ensure all five domains are covered.

How do Wired Assurance Provisioning and Management connect in real workflows?

Provisioning is the initial setup phase where devices are onboarded and cloud connectivity is established. Management and Operations begin once devices are live and reporting health data. Understanding this progression helps you see why provisioning mistakes often surface as operational issues later. Study both together to grasp the complete device lifecycle.

How much hands-on experience is needed to pass JN0-460?

Practical experience with Mist AI dashboards, device onboarding, and basic fabric configuration is valuable but not always required if you study thoroughly. Prioritize labs that cover agent deployment, dashboard navigation, and EVPN-VXLAN configuration if available. If hands-on access is limited, focus on understanding workflows and common troubleshooting patterns through scenario questions.

What are common mistakes that cost points on this exam?

Many candidates confuse EVPN-VXLAN overlay concepts with underlay design, or misunderstand the role of Mist AI in assurance versus traditional monitoring. Others rush through scenario questions without fully reading the symptoms or requirements. Avoid these by carefully studying the distinctions between topics, reading each question completely, and practicing scenario-based items under timed conditions.

What should I review in the final week before the exam?

Focus on high-weight topics (fabric architecture and EVPN-VXLAN) and revisit any questions you marked as uncertain. Create a one-page summary of key concepts: fabric design principles, EVPN-VXLAN configuration steps, and common assurance metrics. Do a final timed practice test to confirm your pacing and identify any last-minute gaps.

Question No. 1

Which statement is correct about a 3-stage campus fabric IP Clos?

Show Answer Hide Answer
Correct Answer: C

Juniper's official Campus Fabric IP Clos design for Mist Wired Assurance defines that the 3-stage IP Clos topology eliminates the traditional distribution layer entirely. This architecture is intended for smaller campus environments that do not need an intermediate distribution layer between the access and core.

''Juniper's Wired Assurance supports 3-Stage and 5-Stage IP Clos deployments. The 3-Stage IP Clos is targeted towards deployments that do not require a Distribution Layer and have smaller scale requirements.''

Because the distribution layer is not present, the only hierarchical connection in a 3-stage campus fabric is between the core and access layers. Traffic is routed directly at the access layer, and each access switch acts as a Layer-3 gateway (IRB) for its VLANs.

''In a campus fabric IP Clos architecture, Mist provisions Layer-3 (L3) integrated routing and bridging (IRB) interfaces on the access layer. All the access switches are configured with the same IP address for each L3 subnet.''

Additionally, the Juniper documentation explains that point-to-point links are configured between layers, and in the case of the 3-stage design (with no distribution), this means between the core and access devices:

''The point-to-point links between each layer utilize /31 addressing to conserve addresses.''

Therefore, the correct statement is C: The core layer is connected to the access layer.

Options A and B incorrectly mention a distribution layer that does not exist in this topology.

Option D is incorrect because core (spine) devices in a Clos fabric are not interconnected with each other.

Question No. 2

A company is planning to deploy a Juniper Mist campus fabric and wants to implement group-based policy (GBP) for microsegmentation.

Which statement is correct in this scenario?

Show Answer Hide Answer
Correct Answer: A

Group-Based Policy (GBP) is a Juniper EVPN-VXLAN feature that enables microsegmentation without requiring multiple VRFs or VLANs. It is implemented within Juniper Mist's Wired Assurance and Campus Fabric frameworks.

''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 for EVPN-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 on all EVPN-capable switches; only on defined platforms (EX4100/EX4400).

Question No. 3

Which campus fabric architecture supports Layer 3 gateways at the distribution layer?

Show Answer Hide Answer
Correct Answer: C

In Juniper's campus fabric architectures, the location of the Layer 3 gateway (IRB) differentiates between CRB and ERB models:

Centrally-Routed Bridging (CRB): L3 gateways are placed at the core layer.

Edge-Routed Bridging (ERB): L3 gateways are placed at the distribution layer, closer to the edge.

''In the ERB model, Layer 2 gateways are deployed at the access layer, and Layer 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 the distribution layer in the ERB architecture.

Question No. 5

Referring to the exhibit, what is the purpose of the Save button in the upper-right corner of the Mist dashboard?

Show Answer Hide Answer
Correct Answer: D

In the Juniper Mist AI for Wired dashboard, administrators can select one or more switch ports (as shown in the exhibit, e.g., port ge-0/0/25 on an EX4100-48MP). Once configuration changes are made --- such as VLAN assignment, port profiles, PoE settings, or administrative state --- the Save button must be clicked to confirm and apply those changes to the device.

''When making configuration changes in the Mist switch interface, the Save button must be used to confirm the modifications. Clicking Save applies the selected port settings to the switch through Mist Cloud.''

Option A is incorrect: saving does not create a backup. Backups and snapshots are handled through Mist's configuration archive, not via the Save button.

Option B is incorrect: Save does not reset configuration; instead, it commits changes.

Option C is incorrect: there is no preview function tied to Save.

Option D is correct: the Save button is explicitly for applying configuration changes to the selected switch or port(s).
