Explanation
The best way to export a list of all deletions for a specific Host Name in the last 24 hours is to go to the Investigate module, access the Detection Activity page, use the filters to focus on the appropriate hostname and time, then export the results. This will allow you to download a CSV file that contains information about all the detections that were deleted for that host in that time period. The other options are either incorrect or not related to exporting deletions. Reference: CrowdStrike Falcon User Guide, page 49.

Explanation
The administrator can assign a Prevention policy to one or more hosts by ensuring the hosts are in a group and assigning that group to a custom Prevention policy. This allows users to apply different prevention settings and options to different groups of hosts based on their needs and preferences. The other options are either incorrect or not applicable to assigning a Prevention policy. Reference: [CrowdStrike Falcon User Guide], page 34.

Explanation
The way to find the older installer file for the Falcon sensor is to click on "Older versions" links under the Host setup and management > Deploy > Sensor downloads. The Sensor downloads page allows you to download the latest version of the Falcon sensor for different operating systems and platforms. However, if you need to install an older version of the sensor, you can click on the "Older versions" links below each sensor download button. This will open a new page where you can select and download any previous version of the sensor1.

Explanation
The option that describes what exclusions can be applied to is that exclusions can be applied to either all hosts or specified groups. An exclusion is a rule that defines what files, folders, processes, IP addresses, or domains should be excluded from detection or prevention by the Falcon sensor. You can create and manage exclusions in the Exclusions page in the Falcon console. You can apply exclusions to either all hosts in your environment or to specific host groups that you select. You cannot apply exclusions to individual hosts selected by the administrator.

Explanation
The option that is true regarding disabling detections for a host is that the detections for that host are removed from the console immediately. No new detections will display in the console going forward unless detections are enabled. This option is essentially a repetition of question 127 and its answer. Disabling detections for a host will remove any existing detections for that host from the console and prevent any new detections from appearing in the console until detections are enabled again1.
