What is the default behavior of a Mist AP if it loses internet access?

Mist APs are engineered for operational continuity even without a connection to the Mist cloud. Each AP downloads and caches its configuration locally. If the Internet connection is lost, the AP continues to function based on this last known good configuration. It will serve existing clients, allow new clients to connect to configured SSIDs, and enforce existing policies. The AP periodically attempts to reconnect to the cloud to sync its state and retrieve any configuration updates.

A. Shutting down radios would cause a complete service interruption, which is contrary to the AP's resilient design.

C. The AP will attempt to reconnect to the cloud but will not enter a disruptive reboot loop.

D. The AP operates as a standalone device with a cached configuration; it does not possess the functionality to become a network controller.

1. Juniper Mist Documentation, "Cloud Connectivity". This page states, "If your APs lose connection to the Mist cloud, they will continue to operate and serve wireless clients based on the last known configuration."

2. Juniper Networks, "Mist AI and Cloud" Datasheet. It highlights "uninterrupted network services during WAN outages" as a key feature, confirming that APs continue to enforce policies with a cached configuration.
