Question 281.

A Falcon administrator wants to identify systems that are no longer checking in and may have stale sensor data. Which information should be reviewed first?

1. Host last-seen and sensor status information
   2. Detection comments
   3. Device Control exceptions
   4. Firewall rule names

Correct Answer: 1. Host last-seen and sensor status information

Explanation:

Host last-seen and sensor status information provides the clearest indication of whether an endpoint is still actively communicating with Falcon. If a host has not checked in recently, the administrator can investigate whether it is offline, decommissioned, experiencing sensor issues, or unable to reach CrowdStrike cloud services. Network connectivity, DNS resolution, proxy settings, and local sensor health may all require review. Detection comments and Device Control settings do not directly show communication health, so host status is the best first place to investigate.

Question 282.

A company wants critical servers to use stricter prevention settings than standard user endpoints. What should the administrator configure?

1. One prevention policy for all endpoints
   2. Separate prevention policies assigned to appropriate host groups
   3. Different dashboard views
   4. Separate analyst accounts only

Correct Answer: 2. Separate prevention policies assigned to appropriate host groups

Explanation:

Different endpoint populations can have different security and operational requirements. Critical servers may need tighter controls than standard user systems, while user endpoints may require settings that better accommodate normal business applications. Separate prevention policies allow these differences to be managed centrally and consistently. Host groups can then be used to target the correct systems. This also supports staged testing before stronger settings are broadly deployed. Dashboard views and analyst accounts do not determine endpoint prevention behavior.

Question 283.

An administrator wants systems matching specific attributes to be automatically organized for policy assignment. Which Falcon feature should be used?

1. Detection exclusions
   2. Real Time Response
   3. Dynamic host groups
   4. Detection comments

Correct Answer: 3. Dynamic host groups

Explanation:

Dynamic host groups automatically include endpoints based on defined criteria. This is useful when hosts with specific operating systems, naming patterns, business roles, or other attributes should receive particular Falcon policies. Instead of manually assigning every endpoint, the administrator can define grouping rules and allow Falcon to maintain membership as systems are added or changed. Real Time Response is used for remote investigation, while detection exclusions alter security behavior. Dynamic groups provide a scalable and consistent approach to policy targeting.

Question 284.

A company wants to block unauthorized removable storage while allowing approved devices when needed. Which capability should be configured?

1. Host containment
   2. Sensor Update Policy
   3. Firewall Management
   4. Device Control**

Correct Answer: 4. Device Control

Explanation:

Device Control allows administrators to govern the use of removable storage and supported peripheral devices on managed endpoints. Policies can allow, block, or restrict device access based on organizational requirements. This can help reduce the risk of unauthorized data transfer, malware introduction, and information leakage. Host containment is intended for incident response, while Firewall Management controls network traffic. Sensor update policies manage Falcon sensor versions. Device Control is therefore the correct capability for controlling removable-media usage.

Question 285.

A Falcon administrator wants to test a newly released sensor version on a limited set of endpoints before broader deployment. What should be configured?

1. A pilot sensor update policy
   2. A global prevention exclusion
   3. A firewall deny rule
   4. A dashboard filter

Correct Answer: 1. A pilot sensor update policy

Explanation:

A pilot sensor update policy allows administrators to deploy a newer Falcon sensor version to a small group of representative endpoints first. This provides time to verify compatibility, performance, and stability before the release is expanded to production systems. If problems occur, the impact remains limited to the pilot group. Detection exclusions and firewall rules do not control sensor version distribution. A staged sensor update approach provides a safer method for adopting new sensor releases while protecting business continuity.

Question 286.

A security responder needs to remotely investigate a suspicious endpoint and inspect files and processes. Which capability should be used?

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

Correct Answer: 2. Real Time Response

Explanation:

Real Time Response allows authorized analysts to remotely interact with Falcon-managed endpoints for investigation and remediation. Depending on permissions, responders can inspect files, processes, directories, and system information and may perform approved response actions. This is especially useful when rapid investigation is required or physical access to the endpoint is not practical. Device Control and sensor update policies serve different administrative purposes. Because Real Time Response provides powerful endpoint capabilities, access should be carefully controlled through appropriate roles and permissions.

Question 287.

A company wants different business units to receive different Falcon policies automatically. What is the most scalable approach?

1. Configure each endpoint manually
   2. Use shared administrator credentials
   3. Use host groups with policy assignments
   4. Add notes to every endpoint

Correct Answer: 3. Use host groups with policy assignments

Explanation:

Host groups provide a scalable way to organize endpoints by business unit, device role, operating system, location, or other relevant characteristics. Policies can then be assigned to those groups instead of being managed individually for every host. Dynamic host groups can automate membership further. Manual per-host configuration becomes difficult to maintain in large environments and increases the risk of inconsistent settings. Group-based policy assignment is therefore a more efficient and reliable approach for managing diverse endpoint populations.

Question 288.

An organization wants to centrally manage supported endpoint firewall settings through Falcon. Which capability should be used?

1. Device Control
   2. Real Time Response
   3. Custom IOAs
   4. Firewall Management**

Correct Answer: 4. Firewall Management

Explanation:

Firewall Management allows administrators to centrally configure and enforce supported endpoint firewall policies. Different rule sets can be assigned to different host groups based on system role or business requirements. This helps maintain consistent inbound and outbound network controls while reducing local configuration drift. Device Control manages removable devices, Real Time Response supports remote investigation, and Custom IOAs provide behavioral detection logic. Firewall Management is therefore the appropriate capability for centralized endpoint firewall administration.

Question 289.

A workstation is confirmed to be communicating with malicious command-and-control infrastructure. What should the security team do immediately?

1. Network contain the workstation
   2. Delete the detection
   3. Disable telemetry
   4. Uninstall the Falcon sensor

Correct Answer: 1. Network contain the workstation

Explanation:

Network containment restricts most communication from a compromised endpoint while preserving the connectivity required for Falcon investigation and response. This can interrupt command-and-control traffic, lateral movement, and data exfiltration while analysts continue examining the system. Deleting the detection does not change endpoint behavior, and uninstalling the sensor or disabling telemetry would reduce security visibility. Containment is therefore the appropriate immediate action when compromise is confirmed and rapid network isolation is required.

Question 290.

A junior analyst needs to view detections but should not be able to use containment or modify policies. What should the administrator configure?

1. Full administrator access
   2. A least-privilege role with only required permissions
   3. Shared administrator credentials
   4. Sensor uninstall rights

Correct Answer: 2. A least-privilege role with only required permissions

Explanation:

Falcon administrative access should follow the principle of least privilege. A junior analyst who only needs to review detections should receive a role that provides the necessary visibility without granting containment, policy modification, or other powerful administrative actions. This reduces the risk of accidental or unauthorized changes. Individual accounts also improve accountability and auditability compared with shared credentials. Proper role-based access helps organizations safely separate operational responsibilities while ensuring users can perform the tasks required by their roles.

Question 291.

A threat hunter wants to determine whether a known malicious IP address has been contacted by other endpoints. Which capability should be used?

1. Threat hunting or event search
   2. Sensor Update Policy
   3. Device Control
   4. Dashboard customization

Correct Answer: 1. Threat hunting or event search

Explanation:

Threat hunting and event-search capabilities allow analysts to query endpoint telemetry for indicators such as IP addresses, domains, file hashes, process names, and command lines. Searching for a malicious IP address can reveal which endpoints communicated with it and help determine the scope of potential compromise. Analysts may also identify associated processes or related activity. Sensor update policies and Device Control manage endpoint configuration rather than historical telemetry. Threat hunting is therefore the appropriate capability for investigating known infrastructure indicators.

Question 292.

A legitimate internal application is repeatedly triggering Falcon prevention actions. What should the administrator do before creating an exclusion?

1. Disable prevention everywhere
   2. Validate the application and create the narrowest justified exception
   3. Remove Falcon from affected endpoints
   4. Ignore all future detections

Correct Answer: 2. Validate the application and create the narrowest justified exception

Explanation:

Exclusions can reduce endpoint protection, so they should be created only after the application has been verified as legitimate and the triggering behavior is understood. If an exception is required, it should be scoped as narrowly as possible to the relevant file, process, path, behavior, or host population where supported. Broad exclusions can create unnecessary blind spots and may hide unrelated malicious activity. Careful validation and narrow scoping help resolve compatibility issues while preserving strong Falcon protection.

Question 293.

A security engineer wants to detect a suspicious process relationship that is specific to the organization’s environment. Which Falcon feature should be considered?

1. Sensor Update Policy
   2. Device Control
   3. Custom Indicators of Attack
   4. Host deletion

Correct Answer: 3. Custom Indicators of Attack

Explanation:

Custom Indicators of Attack allow organizations to create behavior-based detection logic tailored to their own environment. These rules can identify suspicious process relationships, command-line patterns, or execution behavior that may indicate malicious activity. Unlike static indicators, IOAs focus on behavior and can provide broader detection value. Custom IOAs should be tested carefully before broad deployment to reduce false positives or unintended blocking. Sensor update policies and Device Control perform different administrative functions and do not provide custom behavioral detection logic.

Question 294.

A Falcon sensor is installed on an endpoint, but the host never appears in the console. What should the administrator investigate first?

1. Detection comments
   2. Device Control settings
   3. Dashboard theme
   4. Sensor installation, customer identifier, and network connectivity**

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

Explanation:

For an endpoint to appear in Falcon, the sensor must be installed correctly, associated with the proper customer environment, and able to communicate with CrowdStrike cloud services. Administrators should verify installation status, customer identifier information, DNS resolution, proxy settings, firewall access, and general network connectivity. Dashboard themes and Device Control settings do not determine whether a sensor registers successfully. Troubleshooting should therefore begin with enrollment and communication fundamentals before moving to unrelated configuration areas.

Question 295.

A company plans to deploy a significantly stricter prevention policy. What is the safest initial rollout approach?

1. Apply it to a representative pilot group
   2. Deploy it immediately to every endpoint
   3. Disable sensor updates
   4. Remove all existing policies

Correct Answer: 1. Apply it to a representative pilot group

Explanation:

A representative pilot group allows administrators to evaluate the effect of stricter prevention settings before the policy reaches the entire environment. This can reveal false positives, application compatibility problems, performance issues, and unexpected operational impact while limiting disruption. If the pilot behaves as expected, the policy can be expanded gradually. Immediate enterprise-wide deployment increases the chance of widespread disruption if a configuration issue exists. Staged rollout is therefore safer and easier to manage.

Question 296.

An endpoint is receiving a prevention policy intended for another department. What should the administrator review first?

1. Browser history
   2. Host-group membership, policy targeting, and precedence
   3. Detection comments
   4. Local display settings

Correct Answer: 2. Host-group membership, policy targeting, and precedence

Explanation:

Unexpected policy assignment commonly results from host-group membership or policy precedence. An endpoint may belong to multiple groups or match a dynamic grouping rule that the administrator did not anticipate. If more than one policy can apply, precedence determines which configuration becomes effective. Reviewing group membership, policy targeting, and priority is therefore the most direct troubleshooting method. Browser history and display settings do not influence Falcon policy selection. Understanding these relationships is essential for diagnosing policy assignment issues accurately.

Question 297.

A Falcon detection shows active suspicious outbound communication from a corporate laptop. What is the most appropriate immediate response if compromise is likely?

1. Network contain the laptop
   2. Delete the detection
   3. Disable Falcon logging
   4. Uninstall the sensor

Correct Answer: 1. Network contain the laptop

Explanation:

Network containment helps isolate a suspected compromised endpoint from most normal communication while preserving the CrowdStrike connectivity needed for investigation and response. This can interrupt command-and-control traffic, lateral movement, and data exfiltration while responders continue examining the system. Deleting the detection does not change endpoint behavior, while disabling telemetry or uninstalling Falcon would reduce visibility. When compromise is likely and suspicious communications are active, containment is the most appropriate immediate action for reducing network risk.

Question 298.

A company wants critical servers to remain on a validated Falcon sensor version while workstations receive newer versions sooner. What should be configured?

1. Detection exclusions
   2. Separate sensor update policies
   3. Device Control policies
   4. Custom IOAs

Correct Answer: 2. Separate sensor update policies

Explanation:

Separate sensor update policies allow administrators to manage Falcon sensor versions differently across endpoint populations. Critical servers can remain on a tested and approved release for stability, while workstations can adopt newer versions sooner. Host groups can be used to assign the correct update policy to each population. This staged approach helps balance operational reliability with timely access to new capabilities and protection improvements. Detection exclusions, Device Control, and Custom IOAs do not manage sensor version deployment.

Question 299.

A newly created Falcon policy is not applying to several intended endpoints. What should the administrator verify first?

1. Dashboard colors
   2. Screen resolution
   3. Host-group membership, policy assignment, and precedence
   4. Detection comments

Correct Answer: 3. Host-group membership, policy assignment, and precedence

Explanation:

If a Falcon policy is not affecting expected endpoints, the administrator should confirm that those systems belong to the intended host groups and that the policy is correctly assigned. Dynamic group criteria should also be reviewed if membership is automated. If multiple policies can apply, precedence may cause a different configuration to become effective. Dashboard appearance and display settings do not influence policy selection. Reviewing group membership, targeting, and precedence is therefore the most direct way to diagnose unexpected Falcon policy behavior.

Question 300.

Before deploying major Falcon configuration changes across production, what should the administrator validate?

1. Only the policy name
   2. Only the endpoint count
   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 Falcon configuration changes should be validated comprehensively before production rollout. Administrators should confirm that the correct host groups are targeted, understand policy precedence, verify administrative permissions, and test representative endpoints for application compatibility and operational impact. A rollback or recovery plan should also be prepared in case unexpected issues occur. A phased deployment can reduce risk further. Thorough validation helps organizations strengthen endpoint protection while minimizing the chance of widespread disruption from an incorrect or overly aggressive configuration.
