Referring to the exhibit, which percentage of connection attempts failed on the access point named LD_RS_Support?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
The 37% of Successful Connects suggest that 63% failed - however, these are spread between both LD_Testbed_MD and LD_RS_Support. If the only AP with connection issues was LD_RS_Support then the reverse math may have worked.
NEW QUESTION # 33
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?
- A. There is BLE and Wi-Fi co-channel interference.
- B. The clients are connected to the wrong WLAN.
- C. The client devices are not connected to Wi-Fi or to a cellular data plan.
- D. The AP BLE radios do not hear the SDK-enabled client's BLE beacons.
Answer: D
Explanation:
Explanation
If Bluetooth-only mobile client devices with an SDK-enabled app do not appear in the Mist GUI under Clients/App Clients even though they have Bluetooth enabled, it could be because the AP BLE radios do not hear the SDK-enabled client's BLE beacons.
According to the Mist documentation1, Mist SDK is a software development kit that enables indoor location and proximity services using Mist's virtual Bluetooth LE (vBLE) technology. The SDK allows mobile applications to communicate with Mist APs using BLE beacons that are transmitted by the client devices.
The devices with the SDK-enabled app have Bluetooth enabled, but they do not appear in the Mist GUI under Clients/App Clients because the AP BLE radios do not hear the SDK-enabled client's BLE beacons. This could be due to various factors such as interference, distance, obstacles, or configuration issues that affect the BLE signal strength and quality.

NEW QUESTION # 38
You are the only tenant in a building that has Wi-Fi. At times, the Wi-Fi network appears to be slow and you want to determine if the microwave oven is causing an issue because it is used throughput the day. Which SLE metric and classifier should you look at to determine the issue?
- A. throughput/network issues
- B. throughput/coverage
- C. capacity/non-wifi interference
- D. capacity/wifi interference
Answer: C
Explanation:
Reference:
If you are the only tenant in a building that has Wi-Fi and you want to determine if a microwave oven is causing an issue with the Wi-Fi network appearing slow at times, you should look at the capacity/non-wifi interference SLE metric and classifier.
According to the Virtual Network Assistant | Juniper Networks US document, Non-Wi-Fi Interference is a classifier under the Capacity SLE that tracks devices that experience interference from non-Wi-Fi sources such as microwave ovens, cordless phones, or Bluetooth devices. This classifier can help determine if a microwave oven is causing an issue with Wi-Fi performance.
