Question 1

You are asked to set up occupancy analytics for an office that has an existing Mist AP.

Which three types of devices are counted by default? (Choose three.)



Answer : A, B, C

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide3, three types of devices that are counted by default for occupancy analytics are:

Mobile app clients, which are devices that have a mobile app installed with the Mist SDK or BLE beaconing enabled.

Cellular clients, which are devices that have cellular connectivity and can be detected by Mist APs using LTE sensing.

Wi-Fi clients, which are devices that have Wi-Fi connectivity and can be detected by Mist APs using Wi-Fi scanning.


Question 2

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 : C

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.


Question 3

Click the Exhibit button.

Referring to the exhibit, which statement is true?



Answer : C

According to the exhibit, the WLAN has a minimum basic rate of 24 Mbps for both 2.4 GHz and 5 GHz bands. This corresponds to the high-density data rate setting in Mist, which disables all data rates below 24 Mbps. This setting is recommended for high density designs, where clients have enough signal strength and quality to operate at higher rates.


Question 4

You want to identify APs that are not associated with your network. However, the APs broadcast your corporate login page and WLAN name.

What does Mist use to identify APs in this scenario?



Question 5

The customer wants to broadcast a WLAN at a certain time and day of the week.

Which statement is correct in this scenario?
