The correct method is to enter multiple hostnames in the Hostname filter and separate each hostname with a comma. Host Management is designed to let administrators filter, search, and customize host views so they can quickly locate endpoints by attributes such as hostname, grouping tags, IP/CIDR range, operating system version, domain, and other host metadata. A single Hostname filter can accept multiple hostname values, and separating values with commas allows Falcon to treat them as multiple entries within that filter rather than requiring separate filters. Adding the same Hostname filter repeatedly is inefficient and can create unintended filter logic. A decimal is not a valid separator for hostname lists, and there is no separate "Multiple Hostnames" filter in the Host Management workflow. This topic belongs to Host Management and Setup, specifically Host Management filtering, search behavior, and multi-value filter usage.

Because the alert is triggering on a specific Falcon IOA, the correct remediation is to create an IOA exclusion scoped to the relevant file path or behavior. IOA exclusions are specifically intended to reduce false-positive behavioral detections and preventions. A generic file exclusion may be too broad or may not suppress the behavioral IOA. A Custom IOC Allow is more appropriate for hash or indicator-based decisions, not a behavior-based detection. Creating a separate host group with a less restrictive policy weakens protection across development systems and is unnecessarily broad. CCFA guidance favors the narrowest effective exception, applied to the specific detection logic and path involved. Therefore, an IOA exclusion is the correct administrative control.

The Default Sensor Policy is the fallback policy that applies when a host is not matched to another assigned sensor policy. Falcon policy assignment is driven by host group membership and policy precedence. If a host belongs to a group that has an assigned policy, Falcon applies the highest-precedence applicable policy. If the host is not part of any group, or if its groups do not have a policy assigned, Falcon automatically applies the default policy. This ensures every sensor has an update policy path and avoids unmanaged update behavior.
The default policy is not a test mechanism, does not reset all settings, and is not intended to deploy the oldest supported sensor version. The course guide states that the default policy may appear as platform_default and is applied to hosts that do not have an assigned policy. Reference topics: Sensor Deployment, Sensor Update Policies, Default Policy, Host Group Policy Assignment.

The correct location is the Workflow Execution log. Fusion SOAR separates configuration change history from workflow run history. The Workflow Audit log is used to review changes made to workflows, such as edits, versions, or modifications by users. The Execution log is the operational record of workflow activity. It shows every time workflows are triggered, along with execution date, execution status, trigger, action, and workflow name. It also allows administrators to inspect execution details, including whether the workflow completed successfully, failed, or is still in progress. The course guide states that administrators should go to Fusion workflows > Execution log to review each workflow execution and examine where a workflow may have failed. This makes it the correct source for success and failure history. Falcon UI Audit Trail is broader administrative auditing, and Custom Alert History is not the Fusion SOAR execution history location. The correct CCFA topic alignment is Workflows, specifically Fusion SOAR monitoring and execution review.

To patch a network-contained host, create or update a Containment Policy that allowlists the specific IP addresses of the patch management or update sources. Containment blocks most network traffic by design, so update jobs fail unless the required update infrastructure is explicitly permitted. The course guide calls out IP addresses for Windows Update or update sources, not FQDN-based allowlisting, as the supported containment-policy exception method. Content update policies are unrelated to allowing host network traffic during containment. IP Allowlist Management controls administrative access to Falcon from specific source IPs; it does not permit contained endpoints to reach patch servers. Therefore, the containment policy must allow the patch infrastructure IPs.
