Explanation
Once an exclusion is saved, all parts of the exclusion can be changed in the future. The administrator can edit an existing exclusion by selecting it from the Exclusions page and modifying any of its fields, such as pattern, type, option, group or host. The other options are either incorrect or not true of editing exclusions.

Explanation
The Quarantine Manager role can manage quarantined files to release and download. This role allows users to view and search quarantined files, as well as release them from quarantine or download them for further analysis. The other roles do not have this capability.

Explanation
The option that describes how sensor update precedence is determined when a host belongs to more than one host group is that all of the host's groups are examined in aggregate and the policy with highest precedence is applied to the host. A Sensor Update policy is a policy that controls how and when the Falcon sensor is updated on a host. You can create and assign custom Sensor Update policies to different hosts or groups in your environment. Each Sensor Update policy has a precedence value, which determines its priority over other policies. The higher the precedence value, the higher the priority. If a host belongs to more than one host group, each with a different Sensor Update policy assigned, then all of the host's groups are examined in aggregate and the policy with highest precedence among them is applied to the host.
