What is a common cause of inaccurate proximity tracing?

Incorrect placement of BLE beacons or access points, leading to poor signal coverage

Using too many beacons in a small area

The access point firmware being outdated

A logistics company uses Mist proximity tracing to track packages with BLE tags. The system is reporting that packages are sometimes detected in the wrong zone, especially in areas with high shelving. Which approach is most effective to improve zone accuracy?

Increase the BLE transmit power on the tags.

Use GPS-based tracking for the packages.

Reduce the beacon interval on the tags to 50 ms.

Deploy additional Mist APs to provide more RSSI samples.

A shopping mall wants to send a push notification to shoppers when they are near a specific store. They have Mist APs and want to use proximity tracing. Which approach is most appropriate?

Use Wi-Fi triangulation to determine the shopper's exact location.

Enable BLE on the AP and set the beacon interval to 50 ms.

Use GPS geofencing to define the store's location.

Define a proximity zone using BLE RSSI and associate it with the store's AP.

A university uses Mist proximity tracing to alert students when they enter a specific lab. The system is triggering alerts for students in the hallway outside the lab. The lab has glass walls, and the AP is mounted inside the lab. Which adjustment is most effective to reduce hallway triggers?

Raise the RSSI threshold to a less negative value.

Move the AP deeper into the lab, away from the glass wall.

Lower the RSSI threshold to a more negative value.

Increase the BLE transmit power on the AP.

What information does a BLE beacon transmit that is essential for proximity tracing?

A unique identifier (UUID, major, minor) that allows the client to recognize the beacon

The current battery level of the beacon

Proximity Tracing JN0-452 Practice Questions (Page 5)

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.
