Understanding Location Determination in Mist:

Mist uses advanced methods to determine the location of clients in an indoor setting.

Possible Methods:

Triangulation: Uses angles to determine position, but not typically used by Mist.

GPS: Not feasible indoors due to signal limitations.

Probability Surface: Involves calculating the probability of a client's location, but not the primary method used.

Trilateration: Uses the distance from multiple known points to determine the exact location.

Mist's Method:

Mist primarily uses trilateration to determine the location of clients by measuring the distance from at least three access points.

In the context of Mist management, "brownfield" switches refer to those that are already configured and deployed in a network, while "greenfield" switches are new and have no pre-existing configuration.

Mist supports the integration and management of both brownfield and greenfield switches within the same site. The crucial requirement is that all switches, regardless of their initial state, must be running a version of Junos that is supported by Mist.

This compatibility ensures that Mist can apply policies, configurations, and monitoring uniformly across all devices, facilitating a seamless management experience.

Reference: Juniper Networks documentation on Mist AI and Junos compatibility requirements.

When several APs fail to update to the latest firmware during a scheduled downtime, Marvis categorizes this issue as a "non-compliant" action.

This categorization indicates that some APs are not adhering to the intended firmware version policy, which could potentially affect network performance or security.

The non-compliant Marvis Action provides administrators with the necessary information to identify and rectify the issue, ensuring all APs are updated as required.

Reference: Juniper Networks documentation on Marvis Actions and firmware compliance.

Cloud-ready Switch: To use the Wired Visibility option in Juniper Mist Wireless Assurance, a cloud-ready switch must be deployed in the network. This ensures that the switch can communicate effectively with the Mist cloud for management and monitoring.

SNMP Protocol Configuration: The Simple Network Management Protocol (SNMP) must be configured on the switch. SNMP enables the monitoring and management of network devices, allowing Mist AI to collect necessary data for visibility and assurance.

In Mist organizations, only users who have been granted the "invite Admin" permission have the rights to invite new administrators.

This permission is specifically assigned to control who can add new administrators, ensuring that only authorized personnel can extend administrative access.

Managing permissions effectively helps maintain the security and integrity of the organization's network management.

Reference: Juniper Networks documentation on user roles and permissions within Mist organizations.

Mist Cloud Communication Protocol: The Mist cloud platform uses HTTPS (Hypertext Transfer Protocol Secure) to communicate with connected access points. This ensures that the data sent and received is encrypted and secure, adhering to modern security standards​(Juniper Networks)​​(CertEnsure)​.

Security and Reliability: Using HTTPS provides a secure channel over which configuration changes, updates, and monitoring data can be safely transmitted between the Mist cloud and the access points. This protocol is widely accepted and trusted for secure communications over the internet.

Incorrect Options:

MQTT: While MQTT is a lightweight messaging protocol often used in IoT, it is not the protocol used by Mist cloud for AP communication.

SSH: Secure Shell (SSH) is primarily used for secure remote command-line access and not for the primary communication between Mist cloud and APs.

PPTP: Point-to-Point Tunneling Protocol (PPTP) is used for implementing VPNs and is not relevant to the communication between Mist cloud and access points.
