In Mist Cloud, site variables are used to store and reference common configuration values (such as VLAN IDs, subnet addresses, or gateway IPs) that are reused across multiple devices and templates within a site.

''Site variables allow administrators to define reusable configuration parameters that can be referenced in multiple templates or device configurations, ensuring consistency and reducing manual errors.''

Option A: Incorrect --- applies configuration directly, not reusable references.

Option B: Correct --- site variables enable you to reference the same VLAN or value in multiple configurations (switches, WLANs, etc.).

Option C: Incorrect --- WLAN templates are for wireless SSID configuration.

Option D: Incorrect --- switch templates define static configuration but don't store shared variables.

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.

Dynamic Packet Capture (DPC) requires no manual setup.

It is automatically linked to relevant client events on the Insights page, enabling fast root-cause analysis without extra configuration.

Mist Insights and Troubleshooting Guide

Marvis, the AI-driven virtual network assistant in Mist, provides real-time troubleshooting insights for both wired and wireless devices.

When used with Wired Assurance, certain actions require Juniper EX or QFX switches for telemetry collection.

Two of these wired-specific actions are:

Bad Cable Detection -- triggered when electrical faults or poor cable quality are observed through LLDP or physical diagnostics.

Negotiation Mismatch -- triggered when duplex, speed, or link-mode settings are mismatched between peers.

These insights help reduce manual troubleshooting by automating root-cause analysis.

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.
