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

Question

Options

• Aif TX and RX are higher than the rest of the ports
• Bif the port has an MTU greater than 1500 configured
• Cif the port is an STP root port
• Dif the port has a description configured

• A
  78% (21)
• B
  15% (4)
• D
  7% (2)

Explanation

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.
