FSCP Forescout Certified Professional Exam Question and Answers

Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:

According to the Forescout User Directory Plugin Configuration Guide and YouTube tutorial for User Directory integration, the Server Name field is NOT editable once the User Directory server is configured. Once a server configuration is saved, the Server Name cannot be changed; it can only be modified by deleting and reconfiguring the server entry.

User Directory Server Configuration Fields:

According to the User Directory plugin configuration documentation:​

When initially adding a server, these fields are configured:

Server Name - Identifier for the server (e.g., "lab", "production-ad")

Address - IP address or FQDN (e.g., 192.168.1.100)

Port - Connection port (e.g., 389, 636)

Domain - Domain name (e.g., example.com)

Administrator - Account credentials for authentication

Password - Password for the administrator account

Editable Fields After Configuration:

According to the configuration workflow:​​

After the User Directory server is initially configured, the following fields CAN be edited:

Administrator - Can be changed to update authentication credentials

Password - Can be updated if credentials change

Port - Can be modified if the connection port changes

Address - Can be changed to point to a different server

Domain - Can be updated if domain name changes

Non-Editable Field:

According to the User Directory plugin behavior:​

The Server Name is used as the primary identifier for the User Directory server configuration in Forescout. Once created, this identifier cannot be modified because it:

Serves as the unique identifier in the Forescout database

Is referenced by other configurations and policies

Changing it would break existing policy references

Must be deleted and recreated to change

Verification Workflow:

According to the tutorial documentation:​

After creating a User Directory server configuration with:

Server Name: "lab"

Address: 192.168.1.50

Port: 389

Domain: example.com

Administrator: domain\admin

Password: [configured]

Once saved and applied, the Server Name "lab" cannot be edited. To change it, you would need to delete the entire configuration and create a new one with a different name.

Why Other Fields Are Editable:

A. Administrator -✓Editable; credentials may need to be updated

C. Password -✓Editable; security practice requires periodic password changes

D. Address -✓Editable; server may move to a different IP

E. Port -✓Editable; port configuration may change based on security requirements

Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:

According to the Forescout Switch Plugin Configuration Guide, Access Port ACL and Endpoint Address ACL cannot both be used concurrently on the same endpoint. These two actions are mutually exclusive because they both apply ACL rules to control traffic, but through different mechanisms, and attempting to apply both simultaneously creates a conflict.​

Switch Restrict Actions Overview:

The Forescout Switch Plugin provides several restrict actions that can be applied to endpoints:​

Access Port ACL - Applies an operator-defined ACL to the access port of an endpoint

Endpoint Address ACL - Applies an operator-defined ACL based on the endpoint's address (MAC or IP)

Assign to VLAN - Assigns the endpoint to a specific VLAN

Switch Block - Completely isolates endpoints by turning off their switch port

Action Compatibility Rules:

According to the Switch Plugin Configuration Guide:​

Endpoint Address ACL vs Access Port ACL - These CANNOT be used together on the same endpoint because:

Both actions modify switch filtering rules

Both actions can conflict when applied simultaneously

The Switch Plugin cannot determine priority between conflicting ACL configurations

Applying both would create ambiguous filtering logic on the switch

Actions That CAN Be Used Together:

Access Port ACL + Assign to VLAN -✓Can be used concurrently

Endpoint Address ACL + Assign to VLAN -✓Can be used concurrently

Switch Block + Assign to VLAN - This is semantically redundant (blocking takes precedence) but is allowed

Access Port ACL + Switch Block -✓Can be used concurrently (though Block takes precedence)

Why Other Options Are Incorrect:

A. Access Port ACL & Switch Block - These CAN be used concurrently; Switch Block would take precedence

B. Switch Block & Assign to VLAN - These CAN be used concurrently (though redundant)

C. Endpoint Address ACL & Assign to VLAN - These CAN be used concurrently

E. Access Port ACL & Assign to VLAN - These CAN be used concurrently; they work on different aspects of port management

ACL Action Definition:

According to the documentation:​

Access Port ACL - "Use the Access Port ACL action to define an ACL that addresses one or more than one access control scenario, which is then applied to an endpoint's switch port"

Endpoint Address ACL - "Use the Endpoint Address ACL action to apply an operator-defined ACL, addressing one or more than one access control scenario, which is applied to an endpoint's address"

Switch Restrict Actions documentation​

Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:

According to the Forescout Switch Plugin Configuration Guide Version 8.12 and the Switch Properties documentation, the Switch IP/FQDN and Port Name property is used to identify an endpoint's connection location. The documentation explicitly states:​

"The Switch IP/FQDN and Port Name property contains either the IP address or the fully qualified domain name of the switch and the port name (the physical connection point on that switch) to which the endpoint is connected."​

Switch IP/FQDN and Port Name Property:

This property is fundamental for identifying where an endpoint is physically connected on the network. According to the documentation:​

Purpose: Provides the exact physical location of an endpoint on the network by identifying:

Switch IP Address or FQDN - Which switch the endpoint is connected to

Port Name - Which specific port on that switch the endpoint uses

Example: A property value might look like:

10.10.1.50:Port Fa0/15 (IP address and port name)

core-switch.example.com:GigabitEthernet0/1/1 (FQDN and port name)

Use Cases for Location Identification:

According to the Switch Plugin Configuration Guide:​

Physical Topology Mapping - Administrators can see exactly where each endpoint connects to the network

Port-Based Policies - Create policies that apply actions based on specific switch ports

Troubleshooting - Quickly locate endpoints by their switch port connection

Inventory Tracking - Maintain accurate records of device locations and connections

Switch Location vs. Switch IP/FQDN and Port Name:

According to the documentation:​

Property

Purpose

Switch Location

The switch location based on the switch MIB (Management Information Base) - geographic location of the switch itself

Switch IP/FQDN and Port Name

The specific switch and port where an endpoint is connected - physical connection point

Switch Port Alias

The alias/description of the port (if configured on the switch)

The key difference: Switch Location identifies where the switch itself is located, while Switch IP/FQDN and Port Name identifies the specific connection point where the endpoint is attached.

Why Other Options Are Incorrect:

A. Switch Location - Identifies the location of the switch device itself (from MIB), not the endpoint's connection point

B. Switch Port Alias - This is an alternate name for a port (like "Conference Room Port"), not the connection location information

D. Switch Port Action - This indicates what action was performed on a port, not where the endpoint is located

E. Wireless SSID - This is a Wireless Plugin property, not a Switch Plugin property; identifies wireless network name, not switch connection location

Switch Properties for Endpoint Location:

According to the complete Switch Properties documentation:​

The Switch Plugin provides these location-related properties:

Switch IP/FQDN - The switch to which the endpoint connects

Switch IP/FQDN and Port Name - The complete location (switch and port)

Switch Port Name - The specific port on the switch

Switch Port Alias - Alternate port name

Only Switch IP/FQDN and Port Name provides the complete endpoint connection location information in a single property.

According to the Forescout Installation Guide and Working with Appliance Channel Assignments documentation, a Layer-2 channel "Utilizes two interfaces" - one monitor interface and one response interface.​

Layer-2 Channel Structure:

According to the documentation:​

"A channel defines a pair of interfaces used by the Appliance to protect your network. In general, one interface monitors traffic going through the network (the monitor interface), and the other responds to traffic on the network (the response interface)."

Two Interface Components:

According to the Installation Guide:​

Monitor Interface:

Monitors and tracks network traffic

Traffic is mirrored from switch ports

No IP address required

Can be any available interface

Response Interface:

Responds to monitored traffic

Used for policy actions and protections

Configuration depends on VLAN tagging

Can be same VLAN or trunk configuration

Layer-2 vs. Layer-3 Channel:

According to the documentation:​

Layer-2 Channel - Two interfaces (monitor and response)

Layer-3 Channel - Uses IP layer for response

Why Other Options Are Incorrect:

A. Recommended for large number of VLANs - Actually, Layer-2 channels with VLAN tagging are recommended for multiple VLANs, but this doesn't define what a Layer-2 channel is

B. Response interface is a VLAN trunk - While response interface CAN be a trunk for multiple VLANs, it's not required for all configurations

C. Monitor interface is a trunk - The monitor interface receives mirrored traffic; trunk configuration depends on VLAN setup

E. Must be connected to access layer switch - The appliance can connect to various switch types; not specifically limited to access layer

Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:

According to the Forescout Platform Administration Guide and Certificate Configuration documentation, Forescout uses the Online Certificate Status Protocol (OCSP) to verify the revocation status of certificates.​

OCSP in Forescout:

According to the official Forescout documentation:​

"You can also configure the use of Online Certificate Status Protocol (OCSP) and set up validation method failover between CRL and OCSP."

And further:​

"The Forescout Platform supports certificate revocation lists (CRL) and Online Certificate Status Protocol (OCSP) for smart card authentication."

What OCSP Does:

According to the Wikipedia and Fortinet OCSP documentation:​

"The Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate."

OCSP provides:

Real-Time Status Verification - Checks current certificate revocation status

Request/Response Protocol - Sends a query to an OCSP responder

Revocation Status Response - Returns "good," "revoked," or "unknown"

Efficient Alternative to CRL - Smaller data payload than downloading full certificate revocation lists

How OCSP Works:

According to the OCSP documentation:​

Request Sent - Client sends OCSP request to OCSP responder (server operated by CA)

Status Verification - Responder checks revocation status with trusted CA

Response Returned - Responder returns current status, revoked, or unknown

Decision Made - Application (like Forescout) accepts or rejects the certificate based on response

Forescout Smart Card Certificate Validation:

According to the Forescout documentation:​

When using smart card authentication, Forescout:

Supports OCSP - Sends OCSP requests for certificate revocation status

Supports CRL - Also supports Certificate Revocation Lists as fallback

Failover Configuration - Can be configured to use OCSP with CRL fallback

OCSP vs. Certificate Revocation List (CRL):

According to the documentation:​

Aspect

OCSP

CRL

Data Size

Smaller response

Larger list

Update Frequency

Real-time status

Periodic updates

Network Load

Lower burden

Higher burden

Timeliness

Current status

Potentially outdated

Processing

Less complex

More complex parsing

Forescout uses OCSP because it provides real-time, efficient certificate status verification.

Why Other Options Are Incorrect:

A. PKI Certificate Revocation Protocol (PCRP) - This is not a standard protocol; PCRP does not exist

C. Online Revocation Status Protocol (ORSP) - This is not the correct name; the protocol is OCSP, not ORSP

D. Certificate Revocation List Protocol (CRLP) - While Forescout supports CRL, the primary protocol for real-time status is OCSP

E. Certificate Revocation Protocol (CRP) - This is not a standard protocol; the correct protocol is OCSP

According to the Forescout Platform Administration Guide, the logs available from the GUI Console include: Host Details, Policy, Blocking, Event Viewer, and Audit Trail.​

Available Logs from the Forescout Console GUI:

Host Details Log - Provides detailed information about individual endpoints discovered on the network. This log displays comprehensive host properties and status information directly accessible from the console.​

Policy Log - Shows policy activity and records how specific endpoints are handled by policies. The Policy Log investigates endpoint activity, displaying information about policy matches, actions executed, and policy evaluation results.​

Blocking Log - Displays all blocking events that occur on the network, including port blocks, host blocks, and external port blocks. This log provides an at-a-glance display of blocked endpoints with timestamps and reasons.​

Event Viewer - A system log that displays severity, date, status, element, and event information. Administrators can search, export, and filter events using the Event Viewer.​

Audit Trail - Records administrative actions and changes made to the Forescout platform configuration and policies.

How to Access Logs from the GUI:

From the Forescout Console GUI, administrators access logs through the Log menu by selecting:

Blocking Logs to view block events​

Event Viewer to display system events​

Policy Reports to investigate policy activity​

Why Other Options Are Incorrect:

B. Switch, Policy, Blocking, Event Viewer, Audit Trail - "Switch" is not a standalone log type available from the GUI; switch data is captured through plugin logs and reports

C. Switch, Discovery, Threat Protection, Event Viewer, Audit Trail - "Discovery" and "Threat Protection" are report categories, not GUI logs in the standard log menu

D. HPS, Policy, Threat Protection, Event Viewer, Audit Trail - HPS logs are accessed through CLI, not the GUI; "Threat Protection" is a report, not a GUI log

E. Host Details, Policy, Today Log, Threat Event Viewer, Audit Trail - "Today Log" and "Threat Event Viewer" are not standard log names in the Forescout GUI

According to the Forescout Resiliency Solutions User Guide and Failover Clustering configuration documentation, the correct statement is: "Segments should be assigned to appliance folders and NOT to the individual appliances".​

Failover Clustering Folder Structure:

According to the Resiliency Solutions User Guide:​

"When configuring failover: Identify segments of the CounterACT Internal Network that should participate in failover, and assign these segments to the folder."

Key requirement:

"Clear statically assigned segments from Appliances in the failover cluster folder. Appliances in the failover cluster support only the network segments assigned to the folder. They cannot support individually assigned segments."

Segment Assignment Rules:

According to the documentation:​

text

Correct Configuration:

├─ Failover Cluster Folder

│ ├─ Assigned Segments: Segment1, Segment2, Segment3

│ ├─ Appliance A (no individual segments)

│ ├─ Appliance B (no individual segments)

│ └─ Appliance C (no individual segments)

NOT this way:

text

Incorrect Configuration:

├─ Failover Cluster Folder

│ ├─ Appliance A: Segment1

│ ├─ Appliance B: Segment2

│ └─ Appliance C: Segment3

Configuration Steps:

According to the official procedure:​

Create or select an appliance folder

Place appliances in the folder

Assign segments to the FOLDER (not individual appliances)

Clear any statically assigned segments from individual appliances

Configure the folder as a failover cluster

Why Other Options Are Incorrect:

A. Once appliances are configured, then press the Apply button - Failover uses "Configure Failover" button, not "Apply"

C. See failover status by selecting IP Assignments and failover tab - It's the "IP Assignment and Failover pane," not a separate tab

D. Configure the second HA on the Secondary node - Incorrect; failover clustering is configured at the folder level, not on individual nodes

E. Place only the EM to participate in failover - Incorrect; member appliances participate; EM has separate HA

According to the Forescout Administration Guide and List of Properties by Category documentation, NMAP Scanning provides additional discovery details that can assist in correctly profiling hosts when the standard discover properties (OS, Function, Network Function, NIC Vendor) do not provide sufficient information.​

Standard Discovery Properties:

According to the Device Profile Library and classification documentation:​

The standard discovery properties include:

OS - Operating System classification

Function - Network function (printer, workstation, server, etc.)

Network Function - Specific network device role

NIC Vendor - MAC address vendor information

These properties provide basic device identification but may not be sufficient for complete profiling.

NMAP Scanning for Enhanced Profiling:

According to the Advanced Classification Properties documentation:​

"NMAP Scanning - Indicates the service and version information, as determined by Nmap. Due to the activation of Nmap, this..."

NMAP scanning provides advanced discovery including:

Service Banner Information - Service name and version (e.g., Apache 2.4, OpenSSH 7.6)

Open Port Detection - Identifies which ports are open and responding

Service Fingerprinting - Determines exact service versions through banner grabbing

Application Detection - Identifies specific applications and their versions

Why NMAP Provides Additional Details:

According to the documentation:​

When standard properties (OS, Function, NIC Vendor) are insufficient for profiling:

NMAP banner scanning uses active probing of open ports

Returns service version information through banner grabbing

Enables more precise device classification

Helps identify specific applications running on endpoints

Example of NMAP Enhancement:

According to the documentation:

Standard properties might show: "Windows 7, Workstation, Dell NIC"

NMAP scanning additionally shows:

Open ports: 80, 135, 445, 3389

Services: Apache 2.4.41, MS RPC, SMB 3.0

This enables more precise classification (e.g., "Development workstation running web services")

Why Other Options Are Incorrect:

A. Monitoring traffic - While traffic monitoring provides insights, it doesn't provide the specific service and version details that NMAP banner scanning does

B. Packet engine - The Packet Engine provides network visibility through passive monitoring, but not active service version detection like NMAP

C. Advanced Classification - This is a category that encompasses NMAP scanning and other methods, not a specific profiling enhancement

E. Function - This is already listed as one of the discover properties that may be insufficient; it's not an additional tool for profiling

NMAP Configuration:

According to the HPS Inspection Engine documentation:​

NMAP banner scanning is configured with specific port targeting:

text

NMAP Banner Scan Parameters:

-T Insane -sV -p T: 21,22,23,53,80,135,88,1723,3389,5900

The -sV parameter performs version detection, which resolves the Service Banner property.

According to the Windows Update Delivery Optimization documentation and security analysis, the potential security concern with patch delivery optimization for Windows 10 updates is that it CAN BE CONFIGURED to use a peer-to-peer file sharing protocol. While the feature includes security mechanisms like cryptographic signing, the capability to enable P2P sharing does create potential security concerns depending on the configuration.​

Windows Update Delivery Optimization Overview:

According to the Windows Delivery Optimization documentation:​

"Windows Update Delivery Optimization is a feature in Microsoft's Windows designed to improve the efficiency of downloading and distributing updates. Instead of each device independently downloading updates from Microsoft's servers, Update Delivery Optimization allows devices to share update files with each other, either within a local network or over the internet. This peer-to-peer (p2p) approach reduces bandwidth consumption and accelerates the update process."

Configuration Flexibility:

According to the documentation:​

The P2P feature is configurable, not mandated:

Default Setting - By default, Delivery Optimization is enabled for local network sharing

Configurable Options:

PCs on my local network only (safer)

PCs on my local network and the internet (broader sharing, higher risk)

Disabled entirely

Security Concerns Related to P2P Configuration:

According to the security analysis:​

When P2P is enabled, potential concerns include:

Network Isolation Risks - In firewalled or segmented networks, P2P discovery can expose endpoints

Bandwidth Consumption - Improperly configured P2P can saturate network resources

Peer Discovery Vulnerabilities - Devices must discover each other, potentially exposing endpoints

Internet-based Sharing Risks - When "internet peers" are enabled, updates are shared across the internet

Privacy Implications - Devices communicating for update sharing may leak information

Cryptographic Protection Does NOT Eliminate Configuration Risk:

According to the documentation:​

"While Update Delivery Optimization ensures that all update files are cryptographically signed and verified before installation, some organizations may still be concerned about allowing peer-to-peer data sharing."

While the updates themselves are protected, the act of enabling P2P configuration creates the security concern.

Why Other Options Are Incorrect:

B. CounterACT cannot initiate Windows updates for Windows 10 - Incorrect; CounterACT can initiate Windows updates; this is not the security concern

C. It uses peer-to-peer by default - Incorrect; while enabled by default for local networks, internet P2P sharing requires explicit configuration

D. The registry DWORD cannot be changed - Incorrect; the DO modes registry value (DODownloadMode) CAN be changed via GPO or registry

E. It always uses peer-to-peer - Incorrect; P2P is configurable, not mandatory; organizations can disable it entirely

Registry DWORD Configuration Options:

According to the Windows documentation:​

The DODownloadMode DWORD value can be configured to:

0 = HTTP only, no peering (addresses security concern)

1 = HTTP blended with local peering (moderate risk)

3 = HTTP blended with internet peering (higher risk - the security concern)

99 = Simple download mode

This demonstrates that P2P can be configured, which is the security concern mentioned in the question.

Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:

According to the Forescout Installation Guide and Windows Vulnerability DB Configuration Guide, a characteristic of a centralized deployment is that checking Microsoft vulnerabilities at a remote site may have significant bandwidth impact.​

Centralized vs. Distributed Deployment Models:

In a centralized deployment, Forescout uses a central location with Enterprise Manager and Appliances, while in a distributed deployment, appliances are placed at multiple locations.​

Bandwidth Considerations in Centralized Deployments:

According to the Windows Vulnerability DB Configuration Guide:​

"Minimize Bandwidth During Vulnerability File Download: You can minimize bandwidth usage during Microsoft vulnerability file download processes by limiting the number of concurrent HTTP downloads to endpoints. The default is 20 endpoints simultaneously."

The documentation further states:​

"To customize: Select Tools>Options>HPS Inspection Engine>Windows Updates tab. Define a value in the Maximum Concurrent Vulnerability DB File HTTP Uploads field."

This configuration option exists specifically because checking Microsoft vulnerabilities (downloading vulnerability definition files to endpoints and having endpoints upload compliance data back) can consume significant bandwidth.

Why Centralized Deployments Magnify Bandwidth Impact:

According to the Installation Guide:​

In a centralized deployment:

All vulnerability checking traffic flows through a single central location

Multiple endpoints simultaneously download large vulnerability database files

All endpoints upload vulnerability compliance data back to central appliances

All this traffic concentrates at the central site

In contrast, in a distributed deployment where appliances exist at remote sites, local endpoints can communicate directly with the local appliance without impacting the central WAN link.

Bandwidth Management for Centralized Deployments:

According to the documentation:​

To address the bandwidth impact in centralized deployments:

Limit concurrent HTTP uploads for vulnerability DB files

Schedule vulnerability checks during off-peak hours

Carefully plan deployment architecture considering remote site bandwidth

Why Other Options Are Incorrect:

B. Provides enhanced IPS and HTTP actions - This is not specific to centralized deployments; both deployment models can use IPS and HTTP actions

C. Is optimal for threat protection - Neither deployment model is necessarily optimal; choice depends on specific requirements

D. Deployed as a Layer-2 channel - Deployment mode (Layer-2 vs. Layer-3) is independent of centralized vs. distributed architecture

E. Every site has an appliance - This describes a distributed deployment, not a centralized one. In centralized deployments, appliances are concentrated at a central site

Centralized Deployment Characteristics:

According to the documentation:​

Appliances are typically located at a central site

Remote sites connect through WAN links

Reduced operational complexity with centralized management

Higher bandwidth requirements on WAN for vulnerability checking and policy enforcement

Requires careful bandwidth planning for remote vulnerability assessment

Based on the policy condition image provided showing the NOT checkbox on "Windows Antivirus Update Data", the correct statement is that the NOT operator negates the criteria inside the property.​

Understanding the NOT Operator:

When the NOT checkbox is selected on a policy condition property, it performs a logical negation (NOT operation) on the criteria evaluation. According to the Forescout Administration Guide:​

The NOT operator creates an inverted evaluation:

Without NOT: "Windows Antivirus Update Data = [value]"

Result: Matches endpoints where the property equals the specified value

With NOT (as shown in the image): "NOT (Windows Antivirus Update Data = [value])"

Result: Matches endpoints where the property does NOT equal the specified value

How the NOT Operator Works:

The NOT operator negates the criteria inside the property:​

Criteria Evaluation - The property condition is evaluated normally first

Negation Applied - The result is then inverted (TRUE becomes FALSE, FALSE becomes TRUE)

Final Result - The endpoint matches only if the negated condition is true

Example from the Image:

The image shows:

First criterion: "Windows Antivirus Running - 360 Sat" (AND)

Second criterion: "NOT Windows Antivirus Update Data" (checked)

This means:

The endpoint must have Windows Antivirus Running = True (360 Sat)

AND the endpoint must NOT have the Windows Antivirus Update Data property value (whatever was specified)

The NOT negates the criteria inside the property condition

NOT vs. "Evaluate Irresolvable As":

According to the documentation, these are independent settings:​

Purpose

NOT Checkbox

Negates the criteria evaluation (inverts the match logic)

Evaluate Irresolvable As

Defines how to handle unresolvable properties (when data cannot be determined)

The NOT operator works inside the property evaluation, while "Evaluate Irresolvable As" is a separate setting that determines behavior when a property cannot be resolved.

Why Other Options Are Incorrect:

A. Irresolvable hosts would match the condition - The NOT operator doesn't specifically affect how irresolvable properties are handled

C. Negates the criteria outside the property - The NOT operator is internal to the property; it negates the criteria inside, not outside

D. Modifies the irresolvable condition to TRUE - The NOT operator doesn't modify the "Evaluate Irresolvable As" setting; these are independent

E. Negates the "evaluate irresolvable as" setting - The NOT operator and "Evaluate Irresolvable As" are separate; NOT doesn't affect or negate that setting

Policy Condition Structure:

According to the Forescout Administration Guide:​

A policy condition is structured as:

text

[NOT] [Property Name] [Operator] [Value]

Where:

[NOT] - Optional negation operator (what the checkbox controls)

[Property Name] - The property being evaluated

[Operator] - The comparison operator (equals, contains, greater than, etc.)

[Value] - The value to match against

When NOT is checked, it negates the entire criteria evaluation inside that property condition.

The NOT checkbox negates the criteria inside the property. According to the Forescout Administration Guide, when the NOT checkbox is selected on a policy condition criteria, it reverses the logic of that specific criterion evaluation.​

Understanding the NOT Operator in Policy Conditions:

In Forescout policy configuration, the NOT operator is a Boolean logic operator that inverts the result of the property evaluation. When you select the NOT checkbox:

Logical Inversion - The condition is evaluated normally, and then the result is inverted

Criteria Negation - If a criteria would normally match an endpoint, selecting NOT causes it NOT to match

Property-Level Operation - The NOT operator applies specifically to that individual property/criterion, not to the entire rule​

Example of NOT Logic:

Without NOT:

Condition: "Windows Antivirus Running = True"

Result: Matches endpoints that HAVE antivirus running

With NOT:

Condition: "NOT (Windows Antivirus Running = True)"

Result: Matches endpoints that DO NOT have antivirus running

NOT vs. "Evaluate Irresolvable As":

According to the documentation, the NOT operator and "Evaluate Irresolvable As" are independent settings:​

NOT operator - Negates/inverts the criteria evaluation itself

"Evaluate Irresolvable As" - Defines what happens when a property CANNOT be resolved (is irresolvable)

These serve different purposes:

NOT determines what value to match

Evaluate Irresolvable As determines how to handle unresolvable properties

Handling Irresolvable Criteria:

According to the administration guide documentation:​

"If you do not select the Evaluate irresolvable criteria as option, the criteria is handled as irresolvable and the endpoint does not undergo further analysis."

The "Evaluate Irresolvable As" checkbox allows you to define whether an irresolvable property should be treated as True or False when the property value cannot be determined. This is independent of the NOT checkbox.​

Why Other Options Are Incorrect:

A. The NOT checkbox means the "Evaluate Irresolvable as" should be set to True - Incorrect; NOT and Evaluate Irresolvable As are independent settings

B. The external NOT does not change the meaning of "evaluate irresolvable as" - While technically true that NOT doesn't change the Evaluate Irresolvable setting, the answer doesn't explain what NOT actually does

C. Has no effect on irresolvable hosts - Incorrect; NOT negates the criterion logic regardless of whether it's resolvable

E. The NOT checkbox means the "Evaluate Irresolvable as" should be set to False - Incorrect; NOT and Evaluate Irresolvable As are independent

Policy Condition Structure:

According to the documentation, a policy condition consists of:​

Property criteria combined with Boolean logic operators

Individual criterion settings including NOT operator

Irresolvable handling options that are separate from the NOT operator

The Windows Expected Script Result property is the correct answer. According to the official Forescout CounterACT Endpoint Module: HPS Inspection Engine Configuration Guide Version 10.8, the fsprocsvc.exe service is required to run interactive scripts for several CounterACT tasks during Remote Inspection operations on Windows endpoints.​

The documentation explicitly lists the following Properties requiring the fsprocsvc service (with Remote Inspection, i.e., not via SecureConnector):

Windows Expected Script Result ✓

Device Interfaces

Number of IP Addresses

External Devices

Windows File MD5 Signature

Windows Is Behind NAT

Microsoft Vulnerabilities

About fsprocsvc.exe Service:

The fsprocsvc.exe service is a proprietary ForeScout service utility that is downloaded by the HPS Inspection Engine to endpoints. It is used to run interactive scripts for several CounterACT tasks. Key characteristics include:​

Size on disk: Approximately 250KB

Memory acquired during runtime: 2 MB

Runs under: System context

Start type: Automatic

Inactivity timeout: After 2 hours of inactivity, the service stops automatically

Communication: Does not open any new network connection. Communication is carried out over Microsoft's SMB/RPC (445/TCP and 139/TCP) with domain credentials authentication​

Why Other Options Are Incorrect:

A. User Directory Common Name - This property is derived from User Directory plugin queries and does not require fsprocsvc interactive scripting

B. Update Microsoft Vulnerabilities - This is an action, not a property. While Microsoft Vulnerabilities property does require fsprocsvc, "Update" is not the property name listed

D. Antivirus Running - This is a basic WMI-based property that does not require interactive scripting via fsprocsvc

E. Windows Service Running - This is a basic property that can be determined through WMI queries without requiring fsprocsvc interactive scripting

Interactive Scripts Requirement:

According to the HPS Inspection Engine Configuration Guide, WMI does not support interactive scripts on all Windows endpoints. When WMI is used for Remote Inspection, CounterACT uses the fsprocsvc service to run interactive scripts on endpoints that require them. The Windows Expected Script Result property specifically requires running a custom script on the endpoint, which necessitates the fsprocsvc service for proper execution.​

Comprehensive and Detailed Explanation From Exact Extract of Forescout Platform Administration and Deployment:

After managed Windows devices are sent to a policy to determine the Windows 10 patch delivery optimization setting, the best practice is to write sub-rules to check for each of the DWORD values used in patch delivery optimization.​

Windows 10 Patch Delivery Optimization DWORD Values:

Windows 10 patch delivery optimization is configured through DWORD registry settings in the following registry path:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeliveryOptimization​

The primary DWORD value is DODownloadMode, which supports the following values:​

0 = HTTP only, no peering

1 = HTTP blended with peering behind the same NAT (default)

2 = HTTP blended with peering across a private group

3 = HTTP blended with Internet peering

63 = HTTP only, no peering, no use of DO cloud service

64 = Bypass mode (deprecated in Windows 11)

Why Sub-Rules Are Required:

When implementing a policy to manage Windows 10 patch delivery optimization settings, administrators must create sub-rules for each possible DWORD configuration value because:

Different Organizational Requirements - Different departments or network segments may require different delivery optimization modes (e.g., value 1 for some devices, value 0 for others)

Compliance Checking - Each sub-rule verifies whether a device has the correct DWORD value configured according to organizational policy

Enforcement Actions - Once each sub-rule identifies a specific DWORD value, appropriate remediation actions can be applied (e.g., GPO deployment, messaging, notifications)

Granular Control - Sub-rules allow for precise identification of devices with non-compliant delivery optimization settings

Implementation Workflow:

Device is scanned and identified as Windows 10 managed device

Policy queries the DODownloadMode DWORD registry value

Multiple sub-rules evaluate the current DWORD value:

Sub-rule for value "0" (HTTP only)

Sub-rule for value "1" (Peering behind NAT)

Sub-rule for value "2" (Peering across private group)

Sub-rule for value "3" (Internet peering)

Sub-rule for value "63" (No peering, no cloud)

Matching sub-rule triggers appropriate policy actions​

Why Other Options Are Incorrect:

A. Push out the proper DWORD setting via GPO - This is what you do AFTER checking via sub-rules, not what you do after sending devices to the policy

B. Non Windows 10 devices must be called out in sub-rules since they will not have the relevant DWORD - While non-Windows 10 devices should be excluded, the answer doesn't address the core requirement of checking each DWORD value

C. Manageable Windows devices are not required by this policy - This is incorrect; managed Windows devices are the focus of this policy

D. Non Windows 10 devices must be called out in sub-rules so that the relevant DWORD value may be changed - This misses the point; you check the DWORD values first, not change them in sub-rules

According to the Forescout Administration Guide, "Host becomes offline" is NOT an admission event. Admission events are triggers that cause policy rechecks, and according to the documentation:​

What IS an Admission Event:

According to the official documentation:​

"An admission event is a trigger that causes policies to be rechecked. Examples of admission events include:

DHCP Request

IP Address Change

Switch Port Change

Authentication via RADIUS or other authentication servers

Login to an authentication server

New VPN user"​

Specific Admission Events Listed:

According to the Policy Main Rule Advanced Options documentation:​

Admission events include:

DHCP Request - When an endpoint sends a DHCP request

IP Address Change - When an endpoint's IP address changes

Switch Port Change - When an endpoint moves to a different switch port

Authentication Events - When endpoints authenticate to RADIUS or other servers

VPN Events - When VPN users connect

Why "Host becomes offline" is NOT an Admission Event:

According to the documentation:​

A host becoming offline is NOT listed as an admission event. Instead, policies handle offline hosts differently:

By default, policies are rechecked every 8 hours regardless of online/offline status

Offline detection is a property state change, not an admission event

The system tracks whether a host was "seen" or is currently "online," but this doesn't trigger admission event rechecks

Why Other Options ARE Admission Events:

A. DHCP Request ✓- Explicitly listed admission event

B. IP Address Change ✓- Explicitly listed admission event

D. Login to an authentication server ✓- Explicitly listed admission event

E. New VPN user ✓- Explicitly listed admission event

According to the Forescout Administration Guide - Remediate Actions, "Start Antivirus update" is an example of a remediation action.​

Remediation Actions Definition:

According to the Remediate Actions documentation:​

"Remediation actions are actions that address compliance issues by taking corrective measures on endpoints. These actions fix, update, or improve the security posture of non-compliant endpoints."

Examples of Remediation Actions:

According to the documentation:​

Remediation actions include:

Start Antivirus Update - Updates antivirus definitions on the endpoint

Update Antivirus - Updates antivirus software

Start Windows Updates - Initiates Windows security patches

Enable Firewall - Activates Windows firewall

Disable USB - Restricts USB access

Why Other Options Are Incorrect:

A. Start SecureConnector - This is a deployment action, not remediation

C. Assign to VLAN - This is a containment/isolation action (Switch Remediate Action), not a remediation action

D. Switch port block - This is a containment/restrict action (Switch Restrict Action), not remediation

E. HTTP login - This is authentication, not a remediation action

Action Categories:

According to the documentation:​

Based on the policy condition image showing "Does not meet the following criteria", the correct statement is that it negates the criteria as part of the property.​

Understanding "Does not meet the following criteria":

According to the Forescout Administration Guide:​

The "Does not meet the following criteria" radio button option in policy conditions creates a logical negation of the condition:

"Meets the following criteria" - Endpoint matches if the condition is true

"Does not meet the following criteria" - Endpoint matches if the condition is FALSE (negated)

How the Negation Works:

According to the documentation:​

"Use the AND value between both properties: Windows>Manageable Domain>Does not meet the following criteria"

This syntax shows that "Does not meet the following criteria" negates the entire criteria evaluation:

Normal condition: "Windows Antivirus Running = True"

Result: Matches endpoints WITH antivirus running

Negated condition: "Windows Antivirus Running Does not meet the following criteria (= True)"

Result: Matches endpoints WITHOUT antivirus running (negates the criteria)

Negation Happens at Property Level:

The negation is applied as part of the property evaluation, not as a separate NOT operator. When you select "Does not meet the following criteria":

The condition is evaluated normally

The result is then negated/inverted

The endpoint matches only if the negated result is true

Why Other Options Are Incorrect:

B. Modifies the irresolvable condition to TRUE - "Does not meet the following criteria" doesn't specifically affect irresolvable property handling

C. Generates a NOT condition in the sub-rule condition - The negation is part of this property's evaluation, not a separate sub-rule NOT condition

D. Irresolvable hosts would match the condition - "Does not meet the following criteria" doesn't specifically target irresolvable hosts

E. Modifies the evaluate irresolvable condition to FALSE - This setting doesn't affect the "Evaluate irresolvable as" setting
