It does not directly address this incident, which instead calls for: Enable the supported vBLE arrays on the required corridor APs and validate application map integration.

D:

This is relevant to a separate virtual bluetooth low energy problem: A site expects BLE positioning to remain stable after moving access points but never adjusts beam geometry or floorplan references. It does not directly address this incident, which instead calls for: Enable the supported vBLE arrays on the required corridor APs and validate application map integration.

Question 11

A museum wants to analyze which exhibit zones visitors approached but defines no proximity zones or RSSI thresholds on its location map. What should the engineer investigate or configure next?

  1. Create approved proximity zones and appropriate entry and exit thresholds for the intended areas
  2. Choose a supported minimum encounter duration appropriate to the occupancy analysis
  3. Normalize zone definitions and measurement settings before drawing utilization comparisons
  4. Use supported zone, source and passive-device filters and validate them with controlled walkthroughs

Explanation
