A user with a PSK calls you and says, “The Wi-Fi worked for a week and now it does not work.” There have not been any recent configuration changes to the network. You suspect that a time-based setting has reset the key.
In this scenario, where would you begin troubleshooting?
The issue described suggests that the Pre-Shared Key (PSK) has an expiration date, which can reset the key at a specified time or date. Troubleshooting should start at the Site-level Pre-Shared Keys, where such settings are typically managed. This level allows for the assignment and management of expiration dates for the PSK, which aligns with the symptoms described by the user.
PSK Life Cycle Management – PSK Expiration Each PSK can be assigned an expiration date, either during create or edit time. Expiration can be set either at a specified time/date or in certain amount of time (days/weeks/months): https://www.mist.com/documentation/mist-iot-assurance-multi-psk/
there is no PreShared Keys on Organization level You see this on Site-level, so A is the answer.
