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.

Supported Junos Version: For Juniper Mist Wired Assurance to function correctly, the switch must be running a supported Junos version. This ensures compatibility with Mist's cloud management and AI capabilities.

Factory-Default State or Zeroize Command: The switch must boot from a factory-default state, or you can use the request system zeroize command to reset its configuration. This is essential for seamless onboarding and auto-provisioning.

Wired Assurance Guide

An HTTP POST operation performs the 'create' function in web communications. This method sends data to a server to create a new resource. For example, when you submit a form on a website, the data is sent to the server using a POST request, which then creates a new entry in the database.

Web Development Basics

Mist Administrative Logins: Mist administrative logins can utilize Single Sign-On (SSO), allowing administrators to log in using their corporate credentials, enhancing security and ease of access.

Guest User Access: Guest user access cannot use SSO, as SSO is intended for internal users and administrators rather than external guest users who access the network.

Mist SSO Configuration Guide

SSO Integration Overview

To deploy location-based services in Mist, the following components are used:

Location Sensors: These devices capture the location data from BLE tags and other devices.

BLE Tags: These are small devices that emit Bluetooth signals to be picked up by location sensors.

Location Engine: This software processes the data from the sensors and tags to determine precise locations and provide analytics.

Packet Capture: This feature allows for detailed inspection of traffic at the packet level. Capturing packets can help identify issues with authentication protocols, such as misconfigured settings or failures in the authentication exchange process.

Client Events: Monitoring client events provides insights into the client's authentication attempts, including successes and failures. This data helps in pinpointing where in the process the failure occurs, whether at the client, access point, or authentication server.

Juniper Networks Documentation

Google Account Integration: Mist administrators can link their Mist login to a Google account. This facilitates easier access and management of Mist services using a single sign-on (SSO) mechanism provided by Google.

Benefits of SSO: Using Google SSO simplifies user management, reduces password fatigue, and enhances security through Google's robust authentication mechanisms.

Juniper Networks Documentation

Service Level Expectations (SLEs): In Mist AI, SLEs are metrics that define the performance standards for wireless networks in terms of capacity, coverage, and throughput.

Percentage of User Minutes: This metric represents the proportion of time users experience acceptable service levels. It provides a user-centric view of network performance, focusing on the quality of experience over time.
