JN0-460 Exam Questions & Answers

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.

===========

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

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

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

Dynamic Port Configuration (DPC) in Juniper Mist enables automatic switch port configuration based on connected device type (e.g., phones, access points, printers). When setting up DPC, administrators define the matching criteria (such as MAC OUI or LLDP system name) and associate a Configuration Profile that determines which settings are applied.

''To configure Dynamic Port Configuration, you must assign the ports where DPC will run and select the configuration profile that defines how the port will be automatically configured when a matching device is detected.''

Option A: Correct --- you must select the configuration profile to apply once the device type matches.

Option B: Incorrect --- DPC does not use polling; it reacts to real-time LLDP/device discovery.

Option C: Correct --- you must assign the ports on which DPC operates.

Option D: Incorrect --- DPC is supported across EX models running compatible firmware but does not require manually setting a Junos version in configuration.

Wired Assurance defines SLEs (Service Level Expectations) to provide measurable performance indicators for wired networks. These metrics identify root causes of network degradation by monitoring switch health, connection success, and throughput performance.

''Juniper Mist Wired Assurance delivers AI-driven insights across key wired SLEs including Successful Connects, Throughput, and Switch Health, giving visibility into user experience and switch performance.''

Option A (Capacity): Incorrect --- capacity is used in wireless SLEs, not wired.

Option B (Successful Connects): Correct --- tracks connection success rate and anomalies.

Option C (Switch Health): Correct --- monitors hardware, software, and PoE status.

Option D (Coverage): Incorrect --- pertains to wireless SLEs.

Option E (Throughput): Correct --- measures data transfer rate, latency, jitter, and loss.

In Juniper Mist Wired Assurance, SLEs (Service Level Expectations) measure key performance indicators for wired network quality. Throughput SLE monitors data transfer quality, including latency, jitter, and packet loss, which directly impact real-time applications such as voice or video.

''The Throughput SLE provides visibility into end-to-end network performance by tracking latency, jitter, and packet loss, helping identify congestion or quality issues across wired connections.''

Option A (Throughput): Correct --- this SLE includes jitter measurement.

Option B (Successful Connect): Tracks client connection success rate, not jitter.

Option C (Capacity): Monitors link utilization and load, not jitter.

Option D (Switch Health): Monitors device hardware and software health, not traffic performance.
