Explanation
A workflow condition consists of a parameter, an operator, and a value. A workflow condition is a rule that defines when a workflow should be triggered based on certain criteria or filters. A parameter is a variable or attribute that can be used to filter or match detection events, such as severity, tactic, or host group. An operator is a symbol or word that specifies how to compare or evaluate the parameter and the value, such as equals, contains, or greater than. A value is a constant or expression that provides the expected or desired result for the parameter, such as high, credential dumping, or default group1.

Explanation
The administrator can find a list of hosts that have not communicated with the CrowdStrike Cloud in the last
30 days by going to Host setup and management > Managed endpoints > Inactive Sensors. Then, change the time range to 30 days. This will show the host name, last seen date, sensor version and group name for each inactive host. The other options are either incorrect or not available. Reference: [CrowdStrike Falcon User Guide], page 31.

Explanation
The administrator can assign a policy to a specific group of hosts by creating a group containing the desired hosts using "Static Assignment." Then, go to the Assigned Host Groups tab of the desired policy and click
"Add groups to policy." Select the desired Group(s). This will apply the policy to the selected group(s) of hosts. The other options are either incorrect or not applicable to static assignment. Reference: [CrowdStrike Falcon User Guide], page 33.
