What is a common limitation of using RSSI to estimate distance?

RSSI is only available for devices that support GPS

RSSI values are always the same for a given distance

RSSI is affected by environmental factors such as walls, people, and multipath interference

RSSI cannot be measured by access points

Where in the Juniper Mist portal would you configure proximity tracing settings?

Under the 'Location' or 'Subscriptions' section, depending on the feature

Under the 'Access Points' section, as it is a per-AP setting

Under the 'Security' section, as it is a security feature

Under the 'Admin' section, as it requires administrative privileges

A theme park uses Mist proximity tracing to trigger a fast-pass notification when visitors approach a ride entrance. The zone is currently triggering too early, while visitors are still in the queue. Which adjustment is most appropriate?

Change the beacon interval to 50 ms.

Lower the RSSI threshold to a more negative value.

Increase the BLE transmit power on the ride entrance AP.

Raise the RSSI threshold to a less negative value.

Which use case is a typical application of proximity tracing in a retail environment?

Determining the exact aisle where a customer is standing using GPS

Sending a push notification to a shopper's phone when they are near a specific product display

Providing a heatmap of foot traffic across the entire store

Calculating the average dwell time of customers in the store

A conference center uses Mist APs to provide proximity-based check-in for attendees. The system is not triggering check-in until attendees are very close to the AP, even though the zone is set to 5 meters. Which factor is most likely causing this?

The BLE beacon interval is set too high.

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

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

The client's phone has Bluetooth disabled.
