Explanation
Glob syntax is used to specify exclusion patterns to easily exclude files and folders and extensions from detections. Glob syntax allows you to use wildcards (*) and ranges ([a-z]) to match multiple characters or values in a file path or name. For example, you can use glob syntax to exclude all files with .exe extension in a folder by using C:\Folder*.exe as an exclusion pattern2.

Explanation
When a Linux host is in Reduced Functionality Mode (RFM), the sensor would provide minimal protection.
RFM is a mode that limits the sensor's functionality due to license expiration, network connectivity loss, or certificate validation failure. When a Linux sensor is in RFM, it will only provide basic prevention capabilities, such as blocking known malware hashes and preventing script execution from the /tmp directory. The sensor will not send any telemetry or detection events to the Falcon platform, and will not receive any policy or update changes from the Falcon cloud1.

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 role that will allow someone to manage quarantine files is Falcon Security Lead. This role allows users to view and manage quarantined files, as well as release them from quarantine or download them for further analysis. The other roles do not have this capability.
