Question No. 1

What are two functions of Mist Radio Resource Management (RRM)? (Choose two.)

Show Answer Hide Answer
Correct Answer: A, C

Mist Radio Resource Management (RRM) performs several functions including transmit power control and channel assignment which help optimize wireless network performance by dynamically adjusting radio settings based on changing environmental conditions.So,the correct answers are A.transmit power control and C.channel assignment

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, two functions of Mist Radio Resource Management (RRM) are:

Transmit power control, which adjusts the transmit power of APs based on their coverage area and interference level.

Channel assignment, which assigns channels to APs based on their location and interference level.


Question No. 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?

Show Answer Hide Answer
Correct 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 No. 3

Regarding the seven layer OSI networking model, which two layers are different between Ethernet and Wi-Fi? (Choose two.)

Show Answer Hide Answer
Correct Answer: A, D

According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document3, two layers that are different between Ethernet and Wi-Fi in the OSI networking model are:

Media access control (MAC) sub-layer, which is part of the data link layer and defines how devices access and share the wireless medium.

Physical layer, which defines how data is encoded and transmitted over the wireless medium.


Question No. 4

What are two ways to access Marvis? (Choose two.)

Show Answer Hide Answer
Correct Answer: A, B

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, there are two ways to access Marvis, which is a virtual network assistant that provides insights and troubleshooting for wireless networks:

Use the conversational assistant, which allows you to ask natural language questions and get answers from Marvis.

Use Actions, which are predefined queries that you can select from a list and get results from Marvis.
