Question 341.

A Falcon administrator needs to determine which endpoints are running sensor versions below the organization’s approved baseline. What should be reviewed first?

1. Host inventory and sensor version information
   2. Detection comments
   3. USB device events
   4. Firewall rule descriptions

Correct Answer: 1. Host inventory and sensor version information

Explanation:

Host inventory provides centralized visibility into enrolled systems and their installed Falcon sensor versions. By reviewing or filtering this information, an administrator can quickly identify endpoints that are behind the approved baseline. After identifying affected systems, the administrator can review their sensor update policy assignments, connectivity, and recent check-in status to understand why they have not updated. Detection comments and firewall rule descriptions do not provide the primary view of sensor-version compliance. Host inventory is therefore the most appropriate starting point for evaluating sensor currency across the environment.

Question 342.

A SOC manager wants analysts to review detections but restrict Real Time Response access to incident responders. What should be configured?

1. A single shared SOC account
   2. Separate roles with appropriately scoped permissions
   3. One unrestricted role for all analysts
   4. A Device Control policy

Correct Answer: 2. Separate roles with appropriately scoped permissions

Explanation:

Role-based access allows Falcon administrators to grant users only the capabilities required for their responsibilities. Analysts who only need detection visibility can receive limited permissions, while designated responders can receive additional Real Time Response capabilities. This supports least privilege, separation of duties, and stronger accountability. Shared or unrestricted accounts make it more difficult to control high-impact actions and determine who performed them. Properly scoped roles reduce administrative risk while ensuring each security team member has the access necessary to perform assigned tasks.

Question 343.

Several hosts are unexpectedly missing from a dynamic host group. What should the administrator review first?

1. Dashboard colors
   2. Detection severity
   3. Dynamic group criteria and reported host attributes
   4. Sensor installation filename

Correct Answer: 3. Dynamic group criteria and reported host attributes

Explanation:

Dynamic host groups rely on configured membership criteria evaluated against endpoint attributes. If expected hosts are missing, the administrator should compare the group logic with the actual values reported by those systems. Differences in operating system, hostname, tags, or other attributes can prevent a system from matching the rule. Dashboard appearance and detection severity do not affect group membership. Reviewing the group criteria together with actual host data is the most direct method for identifying why systems are not entering the expected dynamic group.

Question 344.

An endpoint was network contained during an incident and has now been fully remediated and validated. What should be done next?

1. Delete the host record
   2. Disable prevention
   3. Uninstall the Falcon sensor
   4. Release the endpoint from containment**

Correct Answer: 4. Release the endpoint from containment

Explanation:

After investigation and remediation are complete, and the security team has confirmed that the endpoint is safe, the containment restriction can be removed. Releasing containment restores normal network communication while keeping Falcon monitoring and prevention active. Before release, the team should verify that malware, persistence, suspicious processes, and other identified issues have been addressed. Deleting the host record or uninstalling Falcon would unnecessarily reduce visibility, while disabling prevention would weaken security. Containment should therefore be removed only after successful validation.

Question 345.

A company wants to deploy a stricter prevention configuration to finance systems with minimal operational risk. What should be done first?

1. Apply the policy to a representative pilot group
   2. Deploy it to all finance systems immediately
   3. Disable the existing prevention policy
   4. Remove all exclusions

Correct Answer: 1. Apply the policy to a representative pilot group

Explanation:

A pilot group allows administrators to evaluate the effect of stricter prevention settings on representative finance systems before wider deployment. This can reveal false positives, application compatibility issues, performance changes, or other operational impacts while limiting potential disruption. If the policy behaves correctly, it can then be expanded gradually to additional endpoints. Applying a restrictive configuration to every finance system immediately increases business risk. A staged rollout provides a safer way to strengthen security while protecting important applications and user productivity.

Question 346.

A trusted application begins generating Falcon detections after a major software upgrade. What should the administrator do before adding an exclusion?

1. Disable Falcon on affected endpoints
   2. Validate the new behavior and create the narrowest necessary exception
   3. Suppress all detections from those hosts
   4. Remove the endpoints from management

Correct Answer: 2. Validate the new behavior and create the narrowest necessary exception

Explanation:

A software upgrade can introduce new behaviors, so the administrator should investigate the activity before assuming it is harmless. Once the application and behavior are validated, an exclusion should be created only if necessary and should be scoped as narrowly as possible. Broad exclusions can create significant security blind spots and may permit unrelated malicious activity to escape detection. Disabling Falcon or suppressing all detections would unnecessarily weaken protection. Careful validation followed by a tightly scoped exception provides a better balance between compatibility and security.

Question 347.

A security engineer wants to detect a specific suspicious parent-child process relationship discovered during a threat-hunting exercise. Which Falcon capability should be considered?

1. Sensor Update Policy
   2. Device Control
   3. Custom Indicators of Attack
   4. Firewall Management

Correct Answer: 3. Custom Indicators of Attack

Explanation:

Custom Indicators of Attack allow organizations to create behavioral detection logic tailored to their environment. They can be used to detect suspicious process relationships, command lines, or execution patterns that security teams have identified during threat hunting, red-team exercises, or previous incidents. Because IOAs focus on behavior rather than only static indicators, they can detect related activity even when file hashes change. Custom rules should be tested carefully before broad deployment to minimize false positives and unintended blocking.

Question 348.

A company wants to manage endpoint firewall configurations centrally through the Falcon platform. Which capability should be used?

1. Device Control
   2. Real Time Response
   3. Host containment
   4. Firewall Management**

Correct Answer: 4. Firewall Management

Explanation:

Firewall Management enables centralized administration of supported endpoint firewall policies. Administrators can define inbound and outbound rules and assign different configurations to specific host groups based on system role or business requirements. This improves consistency and reduces the risk of local firewall configuration drift. Host containment is an incident-response action rather than an ongoing firewall-management method. Device Control manages removable peripherals, while Real Time Response supports investigation and remediation. Firewall Management is therefore the appropriate capability for this requirement.

Question 349.

A threat hunter receives a known malicious SHA-256 hash and wants to determine whether the file appeared elsewhere in the environment. What should be used?

1. Threat hunting or event search
   2. Sensor Update Policy
   3. Device Control
   4. Firewall Management

Correct Answer: 1. Threat hunting or event search

Explanation:

Threat hunting and event-search capabilities allow analysts to query Falcon telemetry for file hashes, domains, IP addresses, processes, command lines, and other indicators. Searching for a known malicious hash can identify other endpoints where the file appeared and provide context about execution or related activity. This helps establish incident scope and prioritize additional investigation or remediation. Sensor update, Device Control, and firewall policies manage endpoint configuration rather than historical telemetry. Threat hunting is therefore the correct capability for searching across endpoint activity.

Question 350.

A company wants testing systems to receive newer Falcon sensor versions before critical production servers. What should be configured?

1. Separate detection exclusions
   2. Separate sensor update policies
   3. Separate dashboard views
   4. Separate detection comments

Correct Answer: 2. Separate sensor update policies

Explanation:

Sensor update policies allow administrators to manage sensor-version deployment differently across endpoint populations. Test systems can receive newer releases first so stability and compatibility can be evaluated before the same version is introduced to critical production servers. Host groups can then be used to assign the appropriate policy to each population. This staged update strategy reduces operational risk on sensitive systems while still allowing the organization to adopt new sensor capabilities in a controlled manner.

Question 351.

A Falcon administrator wants systems in different departments to receive consistent policies without manually configuring every endpoint. What should be used?

1. Host groups with policy assignments
   2. Shared administrator credentials
   3. Manual endpoint comments
   4. Separate dashboard widgets

Correct Answer: 1. Host groups with policy assignments

Explanation:

Host groups provide a scalable method for organizing endpoints according to department, operating system, system role, location, or other meaningful attributes. Policies can then be assigned to groups rather than configured individually for every system. Dynamic host groups can further automate membership. This reduces administrative workload and helps prevent inconsistent endpoint configurations. Shared administrator accounts reduce accountability, while comments and dashboard widgets do not control policy assignment. Group-based administration is therefore the preferred approach for managing large endpoint populations.

Question 352.

An incident responder needs to remotely inspect files, processes, and directories on a suspicious endpoint. Which capability should be used?

1. Sensor Update Policy
   2. Real Time Response
   3. Device Control
   4. Firewall Management

Correct Answer: 2. Real Time Response

Explanation:

Real Time Response enables authorized security personnel to interact remotely with Falcon-managed endpoints during investigations. Depending on permissions, responders can inspect processes, files, directories, and other system information and may perform approved remediation actions. This can significantly accelerate response when physical access is unavailable or when endpoints are geographically distributed. Sensor update and firewall policies serve different administrative purposes, while Device Control manages removable devices. Real Time Response access should be restricted to properly authorized responders because of its powerful capabilities.

Question 353.

A host belongs to multiple groups with different policies of the same type. What determines which policy becomes effective?

1. The endpoint hostname length
   2. The user’s Windows privileges
   3. Policy precedence
   4. The sensor installation date

Correct Answer: 3. Policy precedence

Explanation:

When an endpoint is eligible for multiple policies of the same type, policy precedence determines which applicable policy becomes effective. This is why troubleshooting policy behavior requires reviewing both host-group membership and the order or priority of relevant policies. A host can legitimately belong to several groups while still receiving only the highest-precedence applicable configuration. Local user permissions, hostname length, and sensor installation date do not determine Falcon policy selection. Understanding precedence is therefore essential for predictable endpoint policy administration.

Question 354.

A workstation is confirmed to be communicating with malicious command-and-control infrastructure. What is the most appropriate immediate action?

1. Delete the detection
   2. Disable sensor updates
   3. Remove the sensor
   4. Network contain the workstation**

Correct Answer: 4. Network contain the workstation

Explanation:

Network containment restricts most communication from the compromised workstation while preserving the connectivity required for Falcon investigation and response. This can interrupt command-and-control activity, reduce opportunities for lateral movement, and help prevent additional data exfiltration. Deleting the detection does not affect endpoint behavior, and removing the sensor would eliminate valuable visibility when it is needed most. Containment is therefore the most appropriate immediate action when compromise is confirmed and rapid network isolation is required.

Question 355.

A company wants to block unauthorized removable storage while continuing to allow approved USB peripherals. What should the administrator configure?

1. Device Control policies based on device type and business needs
   2. Network containment for all workstations
   3. Sensor Update Policies
   4. Custom IOAs for every USB device

Correct Answer: 1. Device Control policies based on device type and business needs

Explanation:

Device Control provides policy-based management of supported removable and peripheral devices. Administrators can restrict unauthorized storage devices while allowing approved peripherals required for normal business operations. This is more flexible than disabling all USB functionality and can reduce the risk of data loss or malware introduction without unnecessarily affecting legitimate devices. Network containment is designed for incident response, while sensor update policies manage Falcon versions. Device Control is therefore the appropriate solution for balancing removable-device security with usability.

Question 356.

A Falcon administrator confirms that an application is legitimate and needs an exclusion. What is the best security practice?

1. Exclude the entire drive
   2. Create the narrowest exception that resolves the verified issue
   3. Disable prevention on the endpoint
   4. Ignore all detections from the system

Correct Answer: 2. Create the narrowest exception that resolves the verified issue

Explanation:

The safest exclusion is the smallest one that solves the legitimate compatibility problem. Broad exceptions can create large security blind spots and potentially allow unrelated malicious activity to execute without appropriate detection or prevention. After validating the application, the administrator should limit the exception to the specific file, process, path, behavior, or host population required where supported. Disabling prevention or ignoring all detections from the system would unnecessarily reduce security coverage. Narrow exclusions preserve the strongest practical protection.

Question 357.

A security team wants to create a custom detection for suspicious execution behavior specific to its environment. Which Falcon capability should be considered?

1. Firewall Management
   2. Sensor Update Policy
   3. Custom Indicators of Attack
   4. Host containment

Correct Answer: 3. Custom Indicators of Attack

Explanation:

Custom Indicators of Attack provide a way to define behavior-based detection logic for organization-specific suspicious activity. Teams can use them to identify command-line patterns, process relationships, or other execution behavior associated with known attack techniques or internal threat models. This supplements CrowdStrike’s built-in detections with custom logic. Because poorly designed rules can generate false positives or disrupt legitimate activity, Custom IOAs should be tested on a limited scope before broader use. Firewall and update policies serve different purposes.

Question 358.

A newly installed Falcon sensor never appears in the console. What should the administrator investigate first?

1. Device Control policy
   2. Detection severity
   3. Dashboard layout
   4. Sensor installation, customer identifier, and cloud connectivity**

Correct Answer: 4. Sensor installation, customer identifier, and cloud connectivity

Explanation:

For a host to appear in Falcon, the sensor must be installed successfully, associated with the correct customer environment, and able to communicate with CrowdStrike cloud services. The administrator should verify installation status, customer identifier information, DNS resolution, proxy configuration, firewall access, and general network connectivity. Device Control and dashboard settings do not determine successful sensor registration. Troubleshooting should begin with deployment and connectivity fundamentals before examining unrelated console configurations or security policies.

Question 359.

A Falcon administrator plans a policy change that could affect thousands of endpoints. What should be done before broad deployment?

1. Test the change on a representative pilot group
   2. Apply it immediately to all systems
   3. Remove existing policies
   4. Disable host grouping

Correct Answer: 1. Test the change on a representative pilot group

Explanation:

A representative pilot group allows administrators to validate a significant policy change under realistic conditions without exposing the entire organization to potential disruption. The pilot can reveal false positives, application conflicts, performance problems, or unexpected policy behavior. Once the change performs as expected, rollout can be expanded gradually. Applying an untested policy to thousands of systems creates unnecessary operational risk. A staged deployment therefore provides a safer and more controlled way to introduce major Falcon configuration changes.

Question 360.

Before implementing several major Falcon changes in production, what should the administrator validate?

1. Only policy display names
   2. Only the number of endpoints
   3. Only dashboard visibility
   4. Targeting, precedence, permissions, endpoint impact, and rollback planning**

Correct Answer: 4. Targeting, precedence, permissions, endpoint impact, and rollback planning

Explanation:

Major production changes should be validated comprehensively before rollout. Administrators should confirm that policies target the correct host groups, understand precedence, verify administrative permissions, and test representative endpoints for application compatibility and operational impact. Sensor behavior, exclusions, firewall changes, and other affected controls should be reviewed where relevant. A rollback or recovery plan should also be prepared in case unexpected problems occur. Thorough validation and staged deployment reduce the risk of widespread disruption while maintaining strong Falcon endpoint protection.
