When a Linux sensor enters RFM, it stops processing both events and detections, but it continues sending basic status information such as SensorHeartBeat events to indicate that the sensor is installed. Linux RFM is more restrictive than Windows RFM. On Windows, the sensor may still monitor and report at reduced capacity, but on Linux, unsupported kernel or user-mode requirements can result in no detections or process events. The course guide explains that Linux sensors in RFM do not have detections or process events but continue to send heartbeat status. Therefore, the correct answer is that event and detection processing stop, while basic status continues.
