JNCIS-DC: Juniper Networks Certified Specialist – Data Center — Question 34

You have deployed location services at a site and have installed an application which includes the Mist SDK on Bluetooth-only mobile client devices. The devices with the SDK-enabled app have Bluetooth enabled, but the devices do not appear in the Mist GUI under Clients/App Clients.
What is causing this problem?

Answer options

• A. There is BLE and Wi-Fi co-channel interference.
• B. The clients are connected to the wrong WLAN.
• C. The AP BLE radios do not hear the SDK-enabled client’s BLE beacons.
• D. The client devices are not connected to Wi-Fi or to a cellular data plan.

Correct answer: C

Explanation

The correct answer is C because if the AP BLE radios cannot detect the client's BLE beacons, the devices will not show up in the Mist GUI. Option A is incorrect because while interference can cause issues, it doesn't specifically explain the absence in the GUI. Option B is also wrong as being on the wrong WLAN would not prevent BLE communication. Option D is not applicable since the question specifies Bluetooth-only devices, which do not require Wi-Fi or cellular data to communicate via BLE.
