What information does Mist use to determine if the port is classified as an uplink? (Choose two.)
Juniper Mist automatically classifies ports to simplify visibility and automation within Wired Assurance. The Mist cloud analyzes port telemetry and link behavior to determine port roles, including uplinks.
''Mist uses machine learning and switch telemetry to automatically detect uplinks by analyzing traffic behavior and topology information. Uplink ports typically exhibit higher TX/RX utilization and are identified as spanning-tree root or forwarding ports connecting upstream devices.''
Option A: Correct --- Mist examines traffic statistics. Ports with significantly higher TX/RX utilization relative to others are likely uplinks.
Option B: Incorrect --- MTU size is not a classification criterion.
Option C: Correct --- Mist uses STP information (root or designated port status) to identify uplinks.
Option D: Incorrect --- port description fields are for administrative purposes only and are not used by Mist analytics.

In Juniper Mist cloud services, service level expectation (SLE) telemetry is collected from every device and stored for up to how long?
Juniper Mist AI collects telemetry for Service Level Expectations (SLEs) across wired and wireless devices. This telemetry includes metrics such as time-to-connect, throughput, coverage, and switch performance.
''Service Level Expectation (SLE) data is collected from every device and stored for up to one month in the Mist Cloud. This allows administrators to analyze historical performance trends and troubleshoot issues based on real-time and historical data.''
Option B (2 months): Incorrect --- data is not retained this long.
Option C (7 days): Incorrect --- telemetry retention is longer.
Option D (24 hours): Incorrect --- too short for Mist SLE analytics.
Option A (1 month): Correct --- Mist Cloud retains SLE telemetry for 30 days (1 month).

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

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

Under which hierarchy level would you create a new site configuration?
In the Juniper Mist UI, a site is created under the location hierarchy.
Sites represent logical or physical locations grouping wired and wireless devices for unified management.
