If a customer wants to broadcast a WLAN at a certain time and day of the week, SSID scheduling should be configured

According to the SSID Scheduling - Mist document1, SSID scheduling is a feature that allows you to customize your WLAN by choosing the exact days and times to broadcast the SSID. This feature can be useful for scenarios where you want to limit the availability of a WLAN to a certain time and day of the week.

The exhibit shows a graph of the client’s roaming history over time. The x-axis represents the time and the y-axis represents the access point ID. Each dot on the graph indicates a roam event where the client switched from one access point to another.

The graph shows that the client roamed between different access points multiple times within a short period of time. This indicates that the client was experiencing frequent roams between different access points, which could affect its network performance and user experience.

According to the Location - how it works - Mist document1, a Mist AP actually begins transmitting BLE when it is placed on a floor plan. This is because the Mist cloud uses the floor plan information to calculate the optimal BLE transmission pattern for each AP.

According to the Create a Mist Account and Organization - Mist document1, two fields that are required when creating a new site are:

• Site name, which is a unique identifier for the site within the organization.
• Time zone, which is used to display the correct time for events and reports related to the site.

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.

Referring to the exhibit and considering that it is in the USA, the WLAN with SSID Eero1234 is not configured to industry best practices while the WLAN with SSID NETGEAR24 is configured to industry best practices.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide2, Dynamic Packet Capture is a feature that enables capturing packets from a client device and downloading them as a pcap file. This file can be used for troubleshooting purposes or sent to a vendor for analysis.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide2, a non-compliant AP is an AP that has a different hardware model than what is expected by the cloud configuration. This can happen when an AP is replaced with an incorrect model or when an AP is moved to a different site group that has a different hardware model requirement. The solution is to replace the AP with the correct hardware model.

The impact of adding more SSIDs to a radio is beacon overhead.So,the correct answer is A.beacon overhead

The WLANs with SSIDs NETGEAR24 and Bob24WiFi will cause adjacent channel interference because they are using overlapping channels in the 2.4 GHz frequency band.

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.

According to the Juniper Mist Wireless Deployment Service Datasheet1, a configuration template at the organization level can be applied to a site group, not to an individual site. Therefore, there is no option to mention the site in the config template at the organization level.

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.

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.
