A museum wants to provide an audio guide on visitors' phones when they approach a specific exhibit. They have deployed Mist APs and want to use proximity zones. The audio guide should start when a visitor is within 2 meters of the exhibit. Which configuration in the Mist portal is required to achieve this?

Set the AP's BLE transmit power to maximum to ensure the signal covers the exhibit.

Define a proximity zone with an RSSI threshold and associate it with the exhibit's AP.

Create a geofence around the exhibit using GPS coordinates.

Enable BLE on the visitor's phone and configure the Mist mobile SDK to listen for iBeacon UUIDs.

A library wants to send a notification to patrons when they are near the return desk. They have Mist APs and want to use the Mist mobile SDK. Which configuration is required in the Mist portal to enable this?

Set the AP's BLE transmit power to maximum and enable location services.

Enable BLE on the AP and set the beacon interval to 100 ms.

Create a proximity zone, assign it to the AP, and set an RSSI threshold.

Configure a geofence using the library's GPS coordinates.

A factory uses Mist proximity tracing to alert workers when they enter a hazardous zone. The system is unreliable: sometimes it triggers too early, sometimes too late. The factory floor has heavy machinery and metal structures. Which combination of actions is most likely to improve reliability?

Increase the RSSI threshold and add more APs.

Decrease the RSSI threshold and reduce BLE transmit power.

Add more APs and use a higher RSSI threshold to compensate for signal attenuation.

Use GPS instead of BLE for the hazardous zone.

A stadium uses Mist proximity tracing to send a welcome message to fans when they enter a specific section. The system is inaccurate: some fans receive the message too early, others too late. The stadium has concrete walls and many people moving around. Which factor is most likely causing the inconsistency?

The RSSI threshold is set too low (more negative).

Human bodies absorb BLE signals, causing variable RSSI readings.

The BLE beacon interval is set too high.

The AP's BLE transmit power is set too low.

A warehouse uses Mist proximity tracing to track forklifts equipped with BLE tags. The system reports that forklifts are sometimes detected as being in the wrong zone, especially near metal racks. Which approach is most effective to improve accuracy?

Deploy additional Mist APs to provide more BLE signal coverage.

Increase the BLE transmit power on the tags to overcome interference.

Reduce the beacon interval on the tags to 50 ms.

Switch to GPS-based geofencing for the warehouse.

Proximity Tracing JN0-452 Practice Questions (Page 4)

Part of the Juniper Mist Location-based Services (LBS) domain, which makes up ~15% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–9 in this domain), expect 1–2 from this objective — we provide 25 practice questions to prepare you well beyond it.
