Question 121.

A Falcon administrator wants to quickly identify endpoints that have not communicated with the platform for several days. Which information is most useful?

1. Host last-seen and sensor status data
   2. Detection comments
   3. Firewall rule names
   4. Dashboard color settings

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

Explanation:

Host last-seen information and sensor status are the most useful indicators when determining whether endpoints are still actively communicating with Falcon. Systems that have not checked in for an extended period may be offline, decommissioned, or experiencing sensor or network connectivity problems. After identifying affected hosts, administrators can investigate local sensor health, proxy configuration, DNS resolution, firewall access, or endpoint availability. Detection comments and dashboard appearance do not provide meaningful information about whether a sensor is currently reporting telemetry to the CrowdStrike cloud.

Question 122.

A company wants production servers to receive different malware-prevention settings from developer workstations. What should the administrator configure?

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

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

Explanation:

Production servers and developer workstations often have different operational requirements, applications, and risk profiles. Separate prevention policies allow administrators to tailor protection settings to each endpoint population while keeping management centralized. Host groups can be used to assign the correct policy consistently and make future changes easier to control. This also supports pilot testing before stricter settings are broadly deployed. A single policy may not provide enough flexibility, while dashboard views and analyst accounts do not determine endpoint prevention behavior.

Question 123.

An administrator wants endpoints to be automatically grouped according to operating system and naming convention. Which Falcon feature should be used?

1. Detection suppression
   2. Real Time Response
   3. Dynamic host groups
   4. Device Control

Correct Answer: 3. Dynamic host groups

Explanation:

Dynamic host groups automatically place endpoints into groups when they match configured criteria. This can simplify administration when hosts need to be organized by operating system, naming pattern, role, or other endpoint attributes. Once grouped, systems can receive appropriate prevention, sensor update, firewall, or other policies without manual assignment. This approach is especially useful in large or rapidly changing environments. Real Time Response is used for remote investigation, while Device Control governs peripheral usage. Dynamic grouping is the best choice for automated endpoint organization.

Question 124.

A company wants to block unauthorized removable storage while allowing approved devices. Which capability should the administrator configure?

1. Sensor Update Policy
   2. Custom IOAs
   3. Host containment
   4. Device Control**

Correct Answer: 4. Device Control

Explanation:

Device Control is designed to manage the use of removable media and supported peripheral devices on managed endpoints. Policies can be used to allow, block, or restrict device access according to business and security requirements. This helps reduce the risk of unauthorized data transfer, malware introduction, and information leakage. Sensor update policies manage sensor versions, while Custom IOAs focus on behavioral detection. Host containment is intended for incident response rather than normal removable-device governance. Device Control is therefore the appropriate feature for this requirement.

Question 125.

A Falcon administrator wants to validate a newer sensor build on a limited number of endpoints before broad deployment. What should be used?

1. A dedicated sensor update policy for a pilot group
   2. A global detection exclusion
   3. A new firewall rule
   4. A detection comment workflow

Correct Answer: 1. A dedicated sensor update policy for a pilot group

Explanation:

A dedicated sensor update policy allows the administrator to control which endpoint population receives a specific Falcon sensor version. A small pilot group can receive the newer build first so the organization can evaluate stability, application compatibility, and performance before wider deployment. If issues are discovered, the impact remains limited. Detection exclusions and firewall rules do not manage sensor version rollout. A staged sensor update strategy is a practical way to reduce operational risk while keeping endpoint protection current.

Question 126.

A security responder needs to inspect processes and files remotely on a suspicious endpoint. Which Falcon 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 enables authorized responders to remotely interact with managed endpoints for investigation and remediation. Depending on assigned permissions, analysts can inspect files, processes, directories, network information, and other system artifacts and can perform approved response actions. This capability is especially useful during active incidents because it removes the need for physical access to the device. Device Control and sensor update policies serve different administrative purposes. Because Real Time Response is powerful, access should be carefully restricted through role-based permissions.

Question 127.

A company wants different security teams to manage different endpoint populations more efficiently. What is the most scalable way to organize systems?

1. Manually configure every host
   2. Use shared administrator credentials
   3. Use host groups and policy assignments
   4. Rename every endpoint manually

Correct Answer: 3. Use host groups and policy assignments

Explanation:

Host groups provide a scalable way to organize endpoints by business unit, operating system, location, server function, or other relevant characteristics. Policies can then be assigned to those groups rather than configured individually for each endpoint. This makes administration more consistent and reduces the risk of configuration errors. Dynamic groups can further automate membership. Shared administrator credentials weaken accountability, while manual host-by-host management becomes difficult at scale. Group-based administration is therefore the preferred approach for managing large and diverse Falcon environments.

Question 128.

An organization wants to centrally enforce inbound and outbound firewall rules on managed endpoints. 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 define and enforce supported endpoint firewall policies through Falcon. Different rule sets can be assigned to different host groups based on device role or business requirements. This helps maintain consistent network controls and reduces local configuration drift. Device Control governs removable media, while Real Time Response supports remote investigation. Custom IOAs provide behavioral detection logic rather than firewall administration. Firewall Management is therefore the correct feature when centralized endpoint network policy control is required.

Question 129.

A workstation is believed to be compromised and is communicating with suspicious external systems. What should the security team do first to reduce immediate risk?

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

Correct Answer: 1. Network contain the workstation

Explanation:

Network containment restricts most normal communication from a suspected compromised endpoint while preserving the connectivity required for Falcon investigation and response. This can help stop command-and-control traffic, lateral movement, and data exfiltration while analysts continue investigating the device. Removing the sensor would reduce visibility and response options, while deleting the detection would not affect the endpoint’s behavior. Containment is therefore an appropriate immediate response when a system appears actively compromised and network isolation is needed.

Question 130.

A junior analyst needs to view detections and host details but should not be allowed to modify policies. What should the administrator configure?

1. Full administrator privileges
   2. A least-privilege role with only required access
   3. A shared administrator account
   4. Sensor uninstall permission

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

Explanation:

Falcon administrative access should follow the principle of least privilege. A junior analyst who only needs to review detections and endpoint information should receive a role that provides those capabilities without policy modification, containment, or other powerful administrative permissions. This reduces the risk of accidental or unauthorized changes. Individual accounts also preserve accountability and improve auditing compared with shared credentials. Proper role design helps organizations separate duties while ensuring analysts can perform their assigned responsibilities efficiently and safely.

Question 131.

A threat hunter wants to search endpoint telemetry for connections to a known malicious domain. 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 investigate endpoint telemetry for domains, IP addresses, file hashes, process names, command lines, and other indicators. Searching for a malicious domain can reveal which endpoints communicated with it, when the activity occurred, and which processes may have initiated the connection. This helps determine incident scope and identify additional affected systems. Sensor update policies and Device Control manage endpoint configuration rather than historical telemetry. Threat hunting is therefore the appropriate capability for this investigation.

Question 132.

A trusted application is repeatedly triggering Falcon detections. What should the administrator do before creating an exclusion?

1. Disable prevention for the entire organization
   2. Validate the application and scope the exception as narrowly as possible
   3. Remove Falcon from affected endpoints
   4. Ignore all detections from those systems

Correct Answer: 2. Validate the application and scope the exception as narrowly as possible

Explanation:

Exclusions can reduce endpoint protection, so they should be used only after the application has been confirmed as legitimate and the reason for the detection is understood. If an exception is necessary, it should be limited to the smallest practical scope, such as a specific process, file, path, or host population where supported. Broad exclusions can create unnecessary security gaps and may hide unrelated threats. Careful validation and narrow scoping help resolve compatibility issues while preserving as much Falcon protection as possible.

Question 133.

A security engineer wants to detect a suspicious process behavior that is specific to the organization’s threat model. Which feature should be considered?

1. Host deletion
   2. Sensor update policy
   3. Custom Indicators of Attack
   4. Device Control

Correct Answer: 3. Custom Indicators of Attack

Explanation:

Custom Indicators of Attack allow organizations to create behavioral detection logic tailored to their own environment. These rules can help identify suspicious process relationships, command-line patterns, or execution behavior that the security team considers important. Behavioral detections can be more flexible than static indicators such as file hashes. Custom IOAs should be tested carefully to reduce false positives and avoid unintended blocking. Sensor update policies and Device Control manage endpoint configuration and do not provide organization-specific behavioral detection logic.

Question 134.

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

1. Dashboard filters
   2. Detection comments
   3. USB policy settings
   4. Sensor installation, cloud connectivity, and customer identifier configuration**

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

Explanation:

A Falcon sensor must be installed correctly, associated with the correct customer environment, and able to communicate with CrowdStrike cloud services. If the host never appears in the console, the administrator should verify installation status, customer identifier information, DNS resolution, proxy configuration, firewall access, and general network connectivity. Dashboard filters or Device Control rules do not determine whether a sensor successfully enrolls. Troubleshooting should therefore begin with sensor installation and communication fundamentals before moving to unrelated console settings.

Question 135.

A company is preparing to apply a much stricter prevention policy. What is the safest rollout approach?

1. Test the policy on a representative pilot group first
   2. Apply it immediately to every endpoint
   3. Disable sensor updates
   4. Delete all existing policies

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

Explanation:

Testing a stricter prevention policy on a representative pilot group allows administrators to identify false positives, application compatibility issues, or operational problems before the policy reaches the entire environment. If the pilot performs successfully, the rollout can be expanded gradually. Applying the policy organization-wide immediately creates unnecessary risk because an incorrect setting could disrupt many systems at once. A staged deployment provides a safer balance between improving endpoint protection and maintaining business continuity and application availability.

Question 136.

An endpoint is receiving an unexpected prevention policy. What should the Falcon administrator review first?

1. Browser history
   2. Host-group membership, policy targeting, and precedence
   3. Detection comments
   4. Display resolution

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

Explanation:

Unexpected policy behavior often results from the endpoint’s group memberships or from policy precedence. A system may belong to multiple host groups or may match a dynamic grouping rule the administrator did not expect. If multiple policies apply, precedence determines which one becomes effective. Reviewing group membership, policy targets, and priority is therefore the most direct troubleshooting approach. Browser history and display settings do not influence Falcon policy assignment. Understanding these relationships is essential for diagnosing policy issues accurately.

Question 137.

A Falcon detection shows active suspicious outbound network activity from a laptop. What is the most appropriate immediate action if compromise is suspected?

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 network communication while retaining the CrowdStrike connectivity required for investigation and response. This can interrupt malicious command-and-control traffic, lateral movement, and data exfiltration. Deleting the detection does not change endpoint behavior, while uninstalling the sensor or disabling telemetry would reduce visibility. When active compromise is suspected, containment is an effective immediate action for limiting risk while allowing security teams to continue investigating and remediating the system remotely.

Question 138.

A company wants critical servers to remain on a validated Falcon sensor release while standard workstations upgrade more quickly. What should be configured?

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

Correct Answer: 2. Separate sensor update policies

Explanation:

Separate sensor update policies allow administrators to manage sensor versions independently for different endpoint populations. Critical servers can remain on a thoroughly tested release for stability while standard workstations move to newer versions sooner. Host groups can then be used to assign the correct update policy to each population. This staged lifecycle approach helps balance operational reliability with access to newer features and protections. Detection exclusions and Custom IOAs do not control Falcon sensor version deployment.

Question 139.

A newly created Falcon policy is not affecting several intended hosts. What should the administrator verify first?

1. Dashboard theme
   2. Local display settings
   3. Host-group membership, policy assignment, and precedence
   4. Detection comments

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

Explanation:

If a policy is not affecting expected endpoints, the administrator should confirm that those systems belong to the targeted host groups and that the policy assignment is correct. Dynamic group rules should also be checked when membership is automated. If multiple policies could apply, precedence may cause another configuration to take effect instead. Dashboard appearance and local display settings do not influence policy selection. Reviewing host grouping, policy targeting, and precedence is therefore the most direct way to diagnose the issue.

Question 140.

Before applying major Falcon policy changes across the enterprise, 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 enterprise-wide deployment. Administrators should confirm that the intended host groups are targeted, understand policy precedence, verify administrative permissions, and test the change on representative endpoints. Application compatibility and operational impact should also be evaluated. A rollback or recovery approach should be prepared in case unexpected problems occur. A staged rollout further reduces risk. Comprehensive validation helps strengthen security while minimizing the chance of widespread business disruption.
