The correct statements about creating Mist sites are:

A Mist site can only belong to a single organization. An organization is a logical grouping of sites and devices that share common settings and policies. A site is a physical location that contains one or more Mist devices.A site can only be associated with one organization and cannot be shared or moved to another organization1.

You can create and manage multiple sites with a Mist account. A Mist account is a user account that allows you to access the Mist portal and the Mist API.You can create and manage multiple sites within an organization or across different organizations with a Mist account, depending on your administrator role and permissions2.

The area that you would use to obtain detailed information on a wireless client is theInsightsarea. The Insights area provides a comprehensive view of the wireless network performance and user experience, including the client dashboard, the live view, the service-level expectations (SLEs), and the Marvis virtual network assistant.

The client dashboard allows you to view and search for individual wireless clients and see their connection details, such as device type, MAC address, IP address, SSID, AP name, signal strength, throughput, data usage, location, and more. You can also perform actions on the clients, such as block, unblock, or capture packets.

The live view allows you to monitor the real-time status and activity of the wireless network and clients. You can see the number of connected clients, the traffic volume, the SLE scores, the top APs and SSIDs, and more. You can also filter and drill down into specific clients, APs, SSIDs, or sites.

The SLEs allow you to define and measure the quality of service and user experience for the wireless network. You can set thresholds and goals for key metrics, such as throughput, coverage, capacity, roaming, uptime, and WAN. You can also receive alerts and recommendations when the SLEs are violated.

The Marvis virtual network assistant allows you to interact with the wireless network using natural language commands. You can ask questions, troubleshoot issues, perform actions, and get insights from Marvis. For example, you can ask Marvis to show you the details of a wireless client or to explain why a client had a poor connection.

The protocol that is used by Mist access points to discover third-party switches isLLDP. LLDP stands for Link Layer Discovery Protocol and is a vendor-neutral protocol that allows devices to advertise and discover information about their identity, capabilities, and neighbors on a local area network. LLDP operates on the data link layer (Layer 2) of the OSI model and uses multicast frames to exchange information.

Mist access points use LLDP to discover the switch name, model, firmware version, port number, VLAN ID, and PoE status of the connected third-party switches. This information is then sent to the Mist cloud, where it is processed and displayed in the Mist portal.You can view the switch details and topology in the Switches tab of the Mist portal1. You can also use the Marvis virtual network assistant to query the switch information using natural language commands.

According to theAdministrator Rolespage, the Installer role is based on a timed grace period for Mist site and AP configuration access1.The Installer role has minimum access to the organization and can do the initial installation tasks such as claim AP to Org, assign AP to site, or place on map, etc1.However, the Installer role cannot unclaim or remove the AP from the Org1.The site and AP access for the Installer role is based on a timed grace period after the last modified time, which is by default 7 days1.This means that the Installer role can only access the site and AP for 7 days after the last configuration change1.The Installer role uses the API and Mist AI App, and has no access to the native Admin UI1.

Dynamic packet capture is a Mist AI feature that allows you to capture packets from a specific client or AP without having to log in to the device or use a separate tool1.This feature can help you troubleshoot a client's failed authentication by providing detailed information about the authentication process, such as the EAP type, the RADIUS server, the certificate validation, and the error codes2.You can access the dynamic packet capture feature from the client dashboard or the live view in the Mist cloud portal1.You can also use the Marvis virtual network assistant to initiate a packet capture by using the command 'troubleshoot client <mac-address>'3.
