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 Wikipedia1, 802.1X is an IEEE Standard for port-based network access control (PNAC). It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN using Extensible Authentication Protocol (EAP) over wired IEEE 802 networks and over 802.11 wireless networks, which is known as “EAP over LAN” or EAPOL.

The authentication process involves three parties: a supplicant (the client device), an authenticator (the network device such as an access point), and an authentication server (typically a RADIUS server). The supplicant must provide valid credentials to the authenticator before it can access the network resources.

The credentials are exchanged with a RADIUS server prior to the 4-way Handshake because the 4-way Handshake is used to establish encryption keys between the supplicant and authenticator after successful authentication2. The credentials are exchanged with a RADIUS server after the 802.11 Association because the 802.11 Association is used to establish a logical link between the supplicant and authenticator before authentication can take place3.

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 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.

the Post-Install user role is also known as Installer role, which has a minimum level of access to the org, sites, and APs. It can do the initial installation such as claim AP to Org, assign/unassign AP, or place on map, etc., but cannot unclaim or remove the AP from the Org. Site and AP access is allowed based on timed grace period and/or explicit site access.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, a config template is a configuration object that can be used to apply consistent WxLAN and WLAN policies across all sites within the same organization. A config template can be applied to a site group, which is a collection of sites that share common attributes.

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.

When using location-based services (LBS) at a new warehouse and placing APs on the floor plan with correct scale while ensuring correct location accuracy in this scenario where APs are mounted on trusses 14 feet (4.3 meters) from floor, two actions that should be taken are installing Virtual Beacons in each aisle and configuring height of each AP. So the correct answers are A. Install Virtual Beacons in each aisle and B. Configure height of each AP.

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.
