What is the effect on the DetectionSummaryEvent when detections are disabled for a host?

When detections are disabled for a host, the DetectionSummaryEvent will stop being sent to the Streaming API. This is because the Streaming API is designed to provide real-time updates regarding detection events and other significant activities associated with endpoints managed by the CrowdStrike Falcon platform. When detections are disabled, it indicates that the system will no longer generate or report detection events from that particular host. Consequently, the normal flow of information concerning detections ceases, hence the DetectionSummaryEvent is halted from being directed to the Streaming API.

The other options do not accurately represent what happens in this scenario. The event will not be retained for later submission or exported to a CSV file, as those actions pertain to different functionalities or scenarios within the CrowdStrike Falcon ecosystem. Thus, the key understanding here is that disabling detections results in a complete stop of event reporting to the Streaming API for that host.
