When uninstalling a sensor, a maintenance token is required if the `Uninstall and maintenance protection' setting is enabled within the Sensor Update Policies. This setting prevents unauthorized or accidental uninstallation of sensors by requiring a token that can be generated from the Falcon console. The other options are either incorrect or not related to uninstalling a sensor.

IOC management only allows "Detect only" and "No Action" among the possible actions.
Therefore, it cannot be used to block based on IPs or domains. Custom IOA Rule groups allow to create rule types based on Network Connection (configuring a remote IP address) and domains, and gives the options to "Monitor", "Detect" and "Kill Process", being the late one the closest to
"block".

The purpose of precedence with respect to the Sensor Update policy is that hosts assigned to multiple policies will assume the highest ranked policy in the list (policy with the lowest number).
This means that if a host belongs to more than one group that has different Sensor Update policies assigned, it will use the policy that has the highest precedence (lowest number) among them. The other options are either incorrect or not related to precedence.

A Sensor Update Policy for the Mac platform will only manage Mac operating systems. Sensor Update Policies are platform-specific, meaning that they only apply to hosts that have the same operating system as the policy. For example, a Sensor Update Policy for Windows will only manage Windows hosts, and a Sensor Update Policy for Linux will only manage Linux hosts. You cannot create a Sensor Update Policy that manages multiple operating systems at once.
