NO.10 Asset tracking using Mist-supported third-party BLE beacons has been installed in a warehouse. The BLE beacons were configured using their manufacturer-supplied configuration utility and BLE was properly configured for the site settings. When the warehouse floor plan is opened in Live View, the third-party beacons are not shown.
Which two statements describe causes for this issue? (Choose two.)

The Show assets check box has not been selected in Live View.

Marvis was not enabled for the site.

The Locate this Client as an Asset check box has not been selected at the BLE client level.

The APs are installed at 19 feet from the floor, above the recommended 15 feet.

Explanation
According to the Mist documentation1, asset tracking is a service that allows you to find key assets and people with detailed analytics based on their location using Mist-supported third-party BLE beacons. To enable asset tracking, you need to configure both the BLE beacons and the Mist cloud settings.
The Show assets check box is a setting in Live View that allows you to display or hide the assets on the floor plan2. If this check box is not selected, you will not be able to see the third-party beacons on Live View.
The Locate this Client as an Asset check box is a setting at the BLE client level that allows you to treat a BLE client as an asset for location purposes3. If this check box is not selected, you will not be able to track the BLE client as an asset.

Use the conversational assistant.

Use Actions.

Use Insights.

Use config templates.

Explanation
Two ways to access Marvis are by using the conversational assistant and by using Insights. So the correct answers are A. Use the conversational assistant and C. Use Insights.

NO.13 Which two Mist Aps would be used for BLE location? (Choose two.)

AP12

AP33

AP32

AP43

Explanation
P33 and AP43 are Mist APs that can be used for BLE location.

NO.14 What are two functions of Mist Radio Resource Management (RRM)? (Choose two.)

transmit power control

WLAN scheduling

channel assignment

Ethernet configurations

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.

NO.15 Some users cannot connect to the network. You want to identify these users. In Marvis, which query accomplishes this task?

troubleshoot access points

unhappy clients

troubleshoot clients

list clients

NO.16 Some users cannot connect to the network. You want to identify these users. In Marvis, which query accomplishes this task?

troubleshoot access points

unhappy clients

troubleshoot clients

list clients

According to the Marvis – Mist document, unhappy clients is a query that can be used in Marvis to identify users who cannot connect to the network. Unhappy clients shows a list of clients who have experienced poor service level expectations (SLEs) such as connection failures, coverage issues, or low throughput.

NO.17 A user with a PSK calls you and says, “The Wi-Fi worked for a week and now it does not work.” There have not been any recent configuration changes to the network. You suspect that a time-based setting has reset the key.
In this scenario, where would you begin troubleshooting?

Site-level Pre-Shared Keys

Organization-level Pre-Shared Keys

WLAN-level Pre-Shared Keys

RADIUS Pre-Shared Keys

Explanation
In this scenario, you would begin troubleshooting by checking the WLAN-level Pre-Shared Keys.

NO.18 What information would be streamed through webhooks? (Choose two.)

location coordinates of RFID tags

alerts

SLE metrics of clients

audit logs

NO.19 What do 802.11 stations perform to help avoid collisions on the WLAN medium?

Listen to verify that the medium is free before transmitting.

802.11 stations detect collisions and set a back-off timer.

Transmit on a fixed schedule.

Stations only transmit when polled by the access point.

Reference:
According to the IEEE 802.11 – Wikipedia document, one thing that 802.11 stations perform to help avoid collisions on the WLAN medium is to listen to verify that the medium is free before transmitting. This is part of the carrier-sense multiple access with collision avoidance (CSMA/CA) mechanism that 802.11 stations use to coordinate access to the shared medium.

NO.20 Which two statements are correct about the radio frequency rule of 10s and 3s? (Choose two.)

If the signal strength increases by 3 dB, the power is doubled.

If the signal strength decreases by 10 dB, the power decreases tenfold.

If the signal strength increases by 3 dB, the power is tripled.

If the signal strength decreases by 10 dB, the power is halved.

NO.21 Click the Exhibit button.

Referring to the exhibit, which statement is correct about the Post-Install user’s role?

It is used for help desk monitoring and workflow for all sites.

It has access limited to installing APs and switches at all sites.

It has read-only access to all sites.

It has full access to all sites.

NO.22 Which two events are displayed under the Client Events area found on the Insights page? (Choose two.)

Reassociation

Restart by User

Reflection (Loop Detection)

DHCP Denied

Explanation
Two events that are displayed under Client Events area found on Insights page are Reassociation and DHCP Denied. So the correct answers are A. Reassociation and D. DHCP Denied.

NO.23 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?

There is BLE and Wi-Fi co-channel interference.

The clients are connected to the wrong WLAN.

The AP BLE radios do not hear the SDK-enabled client’s BLE beacons.

The client devices are not connected to Wi-Fi or to a cellular data plan.

NO.24 Once a client discovers an access point, what is the correct order of steps for successful 802.1X authentication?

Open System Authentication -> 802.1X Authentication -> Association

Association -> 802.1X Authentication -> Open System Authentication

Association -> Open System Authentication -> 802.1X Authentication

Open System Authentication -> Association -> 802.1X Authentication

Explanation
Once a client discovers an access point, the correct order of steps for successful 802.1X authentication is Open System Authentication -> Association -> 802.1X Authentication. So the correct answer is D.Open System Authentication -> Association -> 802.1X Authentication.

NO.25 Mist WLAN objects are configurable at which two levels? (Choose two.)

site group

organization

site

access point

According to the Mist documentation1, WLANs are wireless networks that can be configured with different settings such as SSID, security, encryption, authentication, etc. WLANs can be created and managed at different levels of hierarchy in the Mist cloud.
The site group level allows you to create and apply WLANs to a group of sites that share common characteristics or requirements2. This helps you to simplify and standardize your WLAN configuration across multiple sites.
The site level allows you to create and manage WLANs for a specific site that may have unique needs or preferences1. This gives you more flexibility and granularity for your WLAN configuration at each site.
