What command would you use to verify if the Falcon sensor is running on a Windows host?

The command "sc query csagent" is the correct choice for verifying if the Falcon sensor is running on a Windows host. This command uses the Service Control Manager (SCM) utility in Windows to query the status of services. The "csagent" service corresponds to the CrowdStrike Falcon sensor. When you execute this command, it provides detailed information about the service, including whether it is running, stopped, or in a failed state.

Using this command is particularly effective because it directly interacts with Windows services, allowing administrators to get real-time information about the Falcon sensor's operational status on the host system. The other options, while related to system monitoring or installation checks, do not specifically interact with the service control manager, and thus do not provide the precise functionality needed to confirm the active status of the Falcon sensor.
