Get Juniper JN0-460 Exam Practice Questions - Real and Updated

Answer : B, C, D

For greenfield onboarding, switches are newly deployed and must be claimed into Mist Cloud. Juniper Mist offers multiple claim options to simplify large-scale onboarding.

''You can claim switches using the device's QR claim code, by bulk importing from a sales order, or through API-based automation for large deployments. Each of these methods securely associates the devices to your organization in Mist Cloud.''

Option A: Incorrect --- serial number alone is not sufficient for claiming.

Option B: Correct --- claim codes (QR) uniquely identify switches.

Option C: Correct --- bulk claim from a sale order streamlines large deployments.

Option D: Correct --- APIs support automated claiming and provisioning workflows.

Option E: Incorrect --- MAC address alone cannot be used to claim devices.

Juniper Mist Wired Assurance -- API-Based Device Provisioning

Answer : A

Juniper Mist is built on a fully open and RESTful API architecture, allowing programmatic access to all functions.

Administrators and developers can automate switch provisioning, monitoring, and troubleshooting directly via the REST API.

This open design supports JSON data formatting and HTTPS authentication, ensuring secure integration with external systems.

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.

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.

Answer : A, B, C

In Juniper Mist Cloud, administrative roles define what actions a user can perform within an organization. The ability to claim and onboard switches is granted to roles that have configuration or deployment privileges.

''Only users with Super User, Network Admin, or Installer roles can claim, onboard, or delete devices such as access points, switches, or gateways within a Mist organization.''

Option A (Network Admin): Correct --- can claim and manage network devices.

Option B (Installer): Correct --- role specifically intended for device onboarding and site setup.

Option C (Super User): Correct --- full administrative privileges including device claiming.

Option D (Observer): Incorrect --- view-only access.

Option E (Helpdesk): Incorrect --- limited to troubleshooting functions, not device management.
