Juniper JN0-460 Exam - Topic 3 Question 18 Discussion

Posted by Dorian on Jul 16, 2026 at 02:10 AM

What information does Mist use to determine if the port is classified as an uplink? (Choose two.)

Suggested Answer: A, C

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.

I agree with A, but D seems less relevant. Descriptions don’t define uplinks.

I feel like B is also important. MTU size can indicate uplink status.
BO

I think A and C are the right choices. TX and RX matter for uplinks.

Description configured? That can't be it.

Totally agree, TX and RX levels matter!
LE

Wait, MTU over 1500? That seems odd.

I thought it was just about STP root ports.
EV

A and B are the right answers!

I practiced a question similar to this, and I think having a description configured isn't a determining factor for uplinks.
CH

I feel like the STP root port option could be relevant, but I need to double-check how that ties into uplink definitions.
LE

I remember something about MTU sizes, but I can't recall if it specifically has to be over 1500 for uplink classification.
BO

I think it might be related to the TX and RX rates, but I'm not completely sure if that's the only factor.
