Question 851

A campus insists that Bluetooth Low Energy beacons are a Wi-Fi PHY feature using the same 802.11 association process. What is the most defensible next troubleshooting action?

  1. Distinguish BLE location transmissions from 802.11 Wi-Fi client association and data access
  2. Check EHT client capabilities, configured links and negotiated multi-link behavior before promising aggregate performance
  3. Inspect link errors and airtime utilization instead of assuming newer PHY features remove RF loss
  4. Retire unnecessarily slow basic rates after checking legacy device requirements and compatibility

Explanation

Correct Answer

A:

802.11 PHY capability is negotiated per client and is not conferred automatically by an AP marketing label. In the described case, distinguish BLE location transmissions from 802.11 Wi-Fi client association and data access resolves the identified control gap. Confirm with: Separate protocol captures identify BLE advertisements and Wi-Fi management exchanges on their respective radios.
