A hospital reports that IoT medical devices in the ICU are intermittently disconnecting. The SLE dashboard shows the 'Roaming' SLE at 95%, 'Coverage' at 98%, and 'Capacity' at 99%. However, the 'Authentication' SLE is at 80%. Marvis Actions shows a 'RADIUS Timeout' anomaly. The network team has already verified that the RADIUS server is up and reachable. What is the most likely cause of the intermittent disconnects?

The IoT devices are roaming too aggressively between APs, causing authentication to be re-triggered frequently.

The RADIUS server is taking too long to respond to authentication requests, causing the AP to time out and disconnect the client.

The ICU has a coverage gap that causes the devices to lose signal and re-authenticate.

The APs in the ICU are at capacity and are dropping new authentication requests.
