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.
