Question 121
What is the primary purpose of ClusterXL in Check Point R81.20?
A) To provide load balancing for internet traffic
B) To provide high availability and load sharing for Security Gateways
C) To manage multiple security policies
D) To encrypt communication between gateways
Answer: B
Explanation:
ClusterXL provides high availability and load sharing capabilities for Check Point Security Gateways, ensuring continuous security enforcement even when individual gateway members fail. This clustering technology enables organizations to eliminate single points of failure in their security infrastructure while optionally distributing traffic load across multiple gateway members for improved performance and scalability.
ClusterXL operates in two primary modes: High Availability mode where one member actively processes traffic while others remain in standby ready to assume active role upon failure, and Load Sharing mode where multiple members simultaneously process traffic with connections distributed across cluster members. Both modes maintain synchronized state tables ensuring that existing connections continue functioning when failover occurs without requiring connection reestablishment.
The clustering architecture uses virtual IP addresses that clients connect to, with the cluster presenting a unified interface regardless of which physical member processes traffic. State synchronization through the synchronization network ensures all members maintain current connection tables, NAT translations, and security policy enforcement state. Health monitoring through heartbeat mechanisms detects failures triggering automatic failover typically completing in seconds.
While ClusterXL can distribute load, this is not its primary purpose which is high availability. It does not manage multiple security policies which is a management function. Communication encryption between cluster members is a supporting feature rather than the primary purpose. ClusterXL specifically delivers the high availability and optional load distribution capabilities essential for resilient security gateway deployments.
Question 122
Which command is used to check the synchronization status between cluster members in R81.20?
A) cphaprob state
B) cpstat ha
C) fw ctl pstat
D) clusterXL_admin
Answer: A
Explanation:
The cphaprob state command checks the synchronization status and overall health of ClusterXL cluster members in R81.20, displaying critical information including cluster member states, synchronization status, virtual IP addresses, interface priorities, and problem notifications. This diagnostic command is essential for monitoring cluster health, troubleshooting failover issues, and verifying that cluster members are properly synchronized and ready to handle failover events.
The command output shows each cluster member’s status including Active, Standby, or Down states for High Availability mode, or Ready, Active, or Down for Load Sharing mode. The synchronization section indicates whether state synchronization is functioning properly with OK status or experiencing problems. Interface monitoring shows which interfaces are functioning and their priority values affecting failover decisions.
Additional cphaprob commands provide detailed cluster information: cphaprob -a if shows interface status and virtual MAC addresses, cphaprob sync shows detailed synchronization statistics including packets sent and received, cphaprob table shows connection tables and synchronization state, and cphaprob list displays all cluster member information. These commands are critical for cluster administration and troubleshooting.
The cpstat command shows statistics but cpstat ha is not the standard syntax for cluster status. The fw ctl pstat command displays packet statistics rather than cluster synchronization. The clusterXL_admin command is not a standard Check Point command. The cphaprob state command specifically provides the cluster synchronization and member status information administrators need for cluster monitoring.
Question 123
What is the purpose of CoreXL in Check Point R81.20?
A) To provide clustering capabilities
B) To enable multi-core processing for firewall instances
C) To manage central logging
D) To encrypt VPN traffic
Answer: B
Explanation:
CoreXL enables multi-core processing for firewall inspection by creating multiple firewall instances that run in parallel across available CPU cores, dramatically improving performance on modern multi-core processors. This technology allows Check Point Security Gateways to leverage the full processing power of servers with many CPU cores, distributing packet processing workload across firewall instances to achieve near-linear performance scaling.
The architecture creates one firewall instance per allocated CPU core with the Secure Network Distributor acting as a traffic dispatcher that distributes incoming connections across firewall instances using hash-based algorithms. Each firewall instance processes packets independently, enforcing the security policy and performing inspection without contention. The number of firewall instances can be configured based on security requirements and performance needs.
CoreXL provides significant performance benefits for connection-intensive environments where thousands of concurrent connections require processing. The technology is particularly effective for firewall, NAT, and basic VPN processing workloads. However, certain advanced features like threat prevention may benefit from SecureXL which offloads specific processing to acceleration paths. Both technologies can operate simultaneously with SecureXL accelerating accepted traffic and CoreXL handling policy inspection.
Clustering capabilities are provided by ClusterXL rather than CoreXL. Central logging is managed by Log Servers. VPN encryption benefits from CoreXL but encryption is not CoreXL’s purpose. CoreXL specifically enables the multi-core processing architecture that allows modern Security Gateways to achieve high throughput by parallelizing packet inspection across multiple CPU cores.
Question 124
Which file contains the gateway object configuration in R81.20?
A)C
B)fws
C)NDB
D)arp
Answer: A
Explanation:
The objects_5_0.C file contains gateway object configurations and all other network objects including hosts, networks, services, groups, and resource definitions in Check Point R81.20. This critical database file is stored on the Security Management Server and contains the object definitions that administrators create and reference in security policies, NAT rules, and other configuration elements throughout the Check Point environment.
The file is located in the $FWDIR/conf directory on the Management Server and is updated whenever administrators modify objects through SmartConsole or API. When policy installations occur, relevant portions of the objects database are compiled and pushed to Security Gateways along with the security policy. The file uses Check Point’s internal object format encoding network objects, security gateway definitions, user objects, and time objects.
Understanding the objects database structure is important for troubleshooting, backup procedures, and advanced administration tasks. While direct manual editing is not recommended as it can corrupt the database, viewing the file provides insights into object relationships and configuration. Database corruption issues may require restoring from backups or using Check Point database repair utilities.
The rulebases_5_0.fws file contains security policy rule bases rather than objects. The fwauth.NDB file stores user authentication database information. The local.arp file contains local ARP table entries. The objects_5_0.C file specifically stores the comprehensive object database that defines all network objects, services, and gateway configurations used throughout the Check Point environment.
Question 125
What is the purpose of the fw monitor command in R81.20?
A) To monitor CPU usage on gateways
B) To capture and analyze network traffic at multiple inspection points
C) To check cluster synchronization
D) To view active connections
Answer: B
Explanation:
The fw monitor command captures and analyzes network traffic at multiple inspection points within the Check Point firewall packet flow, providing detailed visibility into how packets traverse the security gateway inspection chain. This powerful diagnostic tool is essential for troubleshooting connectivity issues, understanding why packets are dropped, analyzing NAT translations, and debugging complex security policy problems by showing packet transformations at each processing stage.
The command captures packets at four key inspection points in the firewall chain: pre-inbound before any inspection occurs as packets arrive at interfaces, post-inbound after inbound processing but before routing decisions, pre-outbound after routing but before outbound processing, and post-outbound after all processing as packets leave interfaces. This multi-point capture reveals exactly where and why packets are modified or dropped.
Common fw monitor usage includes fw monitor -e “accept host(10.1.1.1);” to capture traffic involving specific hosts, fw monitor -e “accept src=10.1.1.1 and dst=192.168.1.1;” for specific source-destination pairs, and fw monitor -o output.pcap to save captures for analysis in Wireshark. Position notation like i and o in output shows inbound and outbound processing points, while I and O show pre and post inspection points.
CPU monitoring uses cpview or top commands. Cluster synchronization uses cphaprob. Active connections are viewed with fw tab -t connections or SmartConsole. The fw monitor command specifically provides the detailed packet capture and inspection point visibility critical for diagnosing complex firewall processing and troubleshooting network connectivity through Security Gateways.
Question 126
Which feature in R81.20 provides automated malware analysis in a virtual environment?
A) Anti-Bot
B) Threat Emulation
C) Anti-Virus
D) IPS
Answer: B
Explanation:
Threat Emulation provides automated malware analysis by executing suspicious files in isolated virtual sandbox environments, detecting zero-day malware and advanced persistent threats that signature-based detection methods cannot identify. This advanced threat prevention technology analyzes file behavior in controlled environments that mimic production systems, identifying malicious actions like registry modifications, network communications to command and control servers, or attempts to download additional malware.
The Threat Emulation process intercepts files at the gateway, quickly performs initial analysis, and sends suspicious files to Threat Emulation servers for deep inspection. Files are executed in multiple virtual environment configurations matching different operating systems and applications to detect OS-specific or application-specific malware. The behavioral analysis identifies malicious activities even in previously unknown malware variants.
Threat Emulation operates in two modes: Prevent mode where suspicious files are held at the gateway until analysis completes and only clean files are delivered, and Detect mode where files are delivered immediately while analysis continues in the background with alerts generated if malware is detected. The service integrates with ThreatCloud for collective intelligence sharing, allowing new threats detected by one organization to protect all Check Point customers.
Anti-Bot detects and prevents botnet communications but does not analyze files in sandboxes. Anti-Virus uses signature-based detection for known malware. IPS prevents network-based attacks but does not provide file sandboxing. Threat Emulation specifically delivers the advanced behavioral analysis through virtual environment execution that detects zero-day malware and sophisticated threats evading signature-based detection.
Question 127
What is the default port used for CPMI communication between SmartConsole and Security Management Server?
A) 443
B) 18190
C) 19009
D) 257
Answer: B
Explanation:
Port 18190 is the default port used for Check Point Management Interface communication between SmartConsole and the Security Management Server in R81.20. This secure communication channel carries all management traffic including policy editing, object configuration, log queries, and administrative commands between the graphical management interface and the centralized management server.
The CPMI protocol provides the API layer that SmartConsole uses to interact with the management server, supporting authentication, authorization, configuration changes, policy installations, and real-time status monitoring. The communication is encrypted using TLS ensuring confidentiality and integrity of management traffic. Multiple SmartConsole sessions can connect simultaneously to the management server through this port.
Understanding CPMI communication ports is important for firewall rule configuration, troubleshooting connectivity issues between administrators and management servers, and network design where management traffic must traverse security boundaries. The port must be accessible from administrator workstations to the Security Management Server, often requiring dedicated management network segments or specific firewall rules allowing management access.
Port 443 is used for HTTPS access to web interfaces. Port 19009 is used for policy installation from management to gateways. Port 257 is used for traditional GUI client communications in older Check Point versions. Port 18190 specifically handles the CPMI communication that SmartConsole R81.20 uses for all management operations with the Security Management Server.
Question 128
Which command shows the current firewall policy installed on a Security Gateway?
A) fw stat
B) cpstat fw
C) fw getifs
D) show policy
Answer: A
Explanation:
The fw stat command displays comprehensive information about the currently installed firewall policy on a Security Gateway including policy name, installation time, policy type, and the management server that installed the policy. This essential diagnostic command enables administrators to verify which policy version is active, troubleshoot policy installation issues, and confirm that gateways are running the intended security policy.
The command output includes the policy package name, installation date and timestamp, the management server hostname or IP address that pushed the policy, and the administrator who initiated the installation. This information is crucial when troubleshooting issues where gateways may be running outdated policies or when coordinating changes across multiple gateways in distributed environments.
Additional useful policy-related commands include fw ver to show installed product versions and kernel information, cpstat fw to display firewall statistics including packet processing metrics, and fwaccel stat to show hardware acceleration status. For cluster environments, cphaprob state shows cluster status while fw stat shows the policy installed on the local member.
The cpstat fw command displays firewall statistics rather than policy information. The fw getifs command shows configured interfaces and their topology. The show policy command is not a standard Check Point CLI command. The fw stat command specifically provides the installed policy information that administrators need to verify gateway policy status and troubleshoot policy-related issues.
Question 129
What is the purpose of the Global Properties in Check Point R81.20?
A) To define individual gateway settings
B) To configure settings that apply to all gateways managed by the Security Management Server
C) To manage user accounts
D) To configure log server settings
Answer: B
Explanation:
Global Properties configure settings that apply to all Security Gateways managed by the Security Management Server, providing centralized control over fundamental security and networking behaviors, feature enablement, and default configurations that affect gateway operations. This centralized configuration model simplifies administration by setting organization-wide security standards and enabling features globally rather than configuring each gateway individually.
Global Properties sections include Network Address Translation settings controlling NAT behavior and hide NAT configurations, Stateful Inspection settings defining connection timeouts and protocol handling, VPN settings controlling encryption domains and communities, Log and Alert configurations managing how events are reported and processed, and various advanced settings for features like CoreXL, SecureXL, and cluster behavior.
Changes to Global Properties affect all managed gateways when policies are installed, making it important to carefully consider the impact of modifications. Some settings in Global Properties can be overridden at the gateway object level when specific gateways require different configurations. Understanding Global Properties is essential for consistent security enforcement and efficient management of large gateway deployments.
Individual gateway settings are configured in gateway object properties. User account management occurs through user databases and authentication settings. Log server configuration happens in log server object properties. Global Properties specifically provide the centralized configuration mechanism that establishes consistent settings across all managed Security Gateways.
Question 130
Which R81.20 blade provides protection against SQL injection attacks?
A) Application Control
B) IPS
C) Identity Awareness
D) Mobile Access
Answer: B
Explanation:
The Intrusion Prevention System blade provides protection against SQL injection attacks by analyzing application layer traffic for malicious patterns, protocol anomalies, and attack signatures that indicate attempts to inject malicious SQL code into web applications. IPS signatures specifically detect SQL injection attack patterns including union-based injections, time-based blind injections, error-based injections, and other SQL exploitation techniques targeting database-driven web applications.
The IPS blade uses deep packet inspection to examine HTTP requests and responses, matching traffic against an extensive signature database containing patterns for known SQL injection attacks and generic SQL syntax that indicates injection attempts. Protection profiles can be configured for different strictness levels balancing security against false positive risk, with options including Detect mode for alerting only, Prevent mode for blocking attacks, and Inactive for disabled signatures.
IPS protection operates inline analyzing traffic in real-time as it passes through the Security Gateway, blocking malicious requests before they reach vulnerable web applications. Regular signature updates ensure protection against newly discovered attack techniques. Custom signatures can be created for application-specific vulnerabilities or attack patterns unique to particular environments. IPS logs provide detailed information about detected attacks enabling security teams to investigate incidents.
Application Control manages application usage and does not specifically protect against SQL injection. Identity Awareness provides user identification. Mobile Access enables remote access. The IPS blade specifically delivers the application layer attack detection and prevention including SQL injection protection essential for securing web applications.

The system collects logs from all managed Security Gateways, analyzes events in real-time, and correlates related events to identify security incidents that would be invisible when viewing individual log entries. Event policies define which event combinations trigger alerts or notifications, enabling security teams to respond quickly to critical situations. Customizable dashboards and reports provide visibility into attack trends, policy violations, and compliance status.
SmartEvent provides several advanced capabilities including behavioral anomaly detection identifying deviations from normal patterns, geographic threat intelligence showing attack origins on world maps, customizable event definitions for organization-specific security scenarios, scheduled reports for management and compliance audiences, and integration with external SIEM systems through syslog or APIs. The system maintains long-term event storage enabling historical analysis and forensic investigations.
Basic logging capabilities are provided by Log Servers which collect and store logs. Security policy management occurs through SmartConsole. Threat emulation is a separate blade for malware analysis. SmartEvent specifically delivers the advanced event correlation and analysis capabilities that provide security intelligence and enable effective incident detection and response.
Question 132
Which command is used to install security policy on a gateway from the command line?
A) fwm install
B) fw policy
C) cpstop && cpstart
D) policy install
Answer: A
Explanation:
The fwm install command installs security policy on Security Gateways from the command line on the Security Management Server, providing automated policy deployment capabilities useful for scripting, emergency policy pushes, or situations where graphical interface access is unavailable. This command-line interface to policy installation enables integration with automation tools, scheduled policy updates, and rapid policy deployment during incident response.
The basic syntax is fwm install target_gateway management_server where target_gateway specifies the gateway to receive the policy and management_server is typically localhost when run on the management server. Options include -p policy_package to specify a particular policy package when multiple packages exist, and -s to synchronize connections after installation. The command returns installation status indicating success or failure with error details.
Policy installation from command line requires appropriate permissions with the administrator running the command having policy installation rights for the target gateways. The management server must have connectivity to target gateways through policy installation communication channels typically port 18190 and 18191. Installation logs are written to standard Check Point log locations enabling troubleshooting of failed installations.
The fw policy command is not a standard installation command. The cpstop and cpstart commands restart Check Point services but do not install policies. The policy install command uses incorrect syntax. The fwm install command specifically provides the command-line policy installation capability essential for automation and emergency policy deployment scenarios.
Question 133
What is the purpose of SecureXL in R81.20?
A) To provide clustering capabilities
B) To accelerate traffic by offloading accepted connections from firewall inspection
C) To manage SSL inspection
D) To control application usage
Answer: B
Explanation:
SecureXL accelerates traffic by offloading accepted connections from firewall inspection, creating fast-path processing for established connections that have already passed security policy inspection. This performance optimization technology identifies connections that are allowed by security policy, adds them to acceleration tables, and processes subsequent packets from those connections without full firewall inspection, dramatically improving throughput and reducing latency for accepted traffic.
The acceleration architecture operates in two modes: Firewall Path processes packets through normal firewall inspection performing security policy evaluation, NAT, and logging, while Accelerated Path handles packets from established connections using streamlined processing that maintains connection state without policy re-evaluation. The Secure Network Distributor determines which path processes each packet based on connection state and template tables.
SecureXL provides significant performance improvements particularly for environments with long-lived connections and high packet rates. The technology is most effective after the initial connection establishment as subsequent packets are accelerated. Certain features that require packet content inspection like threat prevention may disable acceleration for specific connections. The fwaccel stat command shows acceleration statistics and enabled status.
Clustering capabilities are provided by ClusterXL. SSL inspection is a separate blade functionality. Application Control manages application usage. SecureXL specifically delivers the performance acceleration through connection offloading that enables Security Gateways to achieve high throughput by avoiding redundant inspection of already-approved traffic.
Question 134
Which authentication method allows users to authenticate based on their source IP address in R81.20?
A) Password authentication
B) Agent-based authentication
C) Transparent authentication
D) Manual authentication
Answer: C
Explanation:
Transparent authentication allows users to authenticate based on their source IP address without requiring explicit authentication prompts, leveraging existing authentication information from domain controllers or other identity sources to associate IP addresses with user identities. This seamless authentication approach enables Identity Awareness features and user-based policy enforcement without impacting user experience or requiring agent deployment.
Transparent authentication mechanisms include Active Directory integration using PDC query to poll domain controllers for user login information, browser-based authentication using captive portal with single sign-on integration, RADIUS accounting for associating IP addresses with authenticated users from 802.1X or VPN sessions, and terminal servers integration for multi-user systems where multiple users share IP addresses.
The technology enables administrators to create security policies based on user identities rather than just IP addresses, providing more granular control and better visibility into who is accessing resources. Policies can allow or restrict access based on Active Directory groups, implement different rules for different users accessing the same resources, and generate logs showing user identities rather than only IP addresses improving audit trails and forensic capabilities.
Password authentication requires users to enter credentials. Agent-based authentication requires software agents on endpoints. Manual authentication involves explicit user authentication actions. Transparent authentication specifically provides the seamless identity association through IP address correlation that enables Identity Awareness without user interaction or endpoint agent requirements.
Question 135
What is the purpose of the vpn tu command in R81.20?
A) To configure VPN communities
B) To test VPN tunnel connectivity and troubleshoot encryption issues
C) To install VPN policy
D) To generate VPN certificates
Answer: B
Explanation:
The vpn tu command tests VPN tunnel connectivity and troubleshoots encryption issues by sending test traffic through VPN tunnels and reporting on encryption domain matching, tunnel establishment, and packet encryption status. This essential diagnostic tool helps administrators verify that VPN configurations are correct, identify why tunnels fail to establish, and troubleshoot intermittent VPN connectivity problems.
Common vpn tu usage includes vpn tu to display the test utility menu with options for various tests, vpn tu followed by remote peer IP address to test tunnel establishment to specific peers, and options to specify source and destination IP addresses to verify encryption domain matching. The command shows whether traffic would be encrypted, which tunnel would be used, and identifies configuration mismatches preventing tunnel establishment.
The output indicates whether encryption domains are properly configured on both peers, whether IKE phase 1 and phase 2 negotiations would succeed with current configurations, which VPN community applies to the tested traffic, and detailed error messages when configurations prevent tunnels from establishing. This information is invaluable for troubleshooting complex VPN configurations with multiple communities and overlapping encryption domains.
VPN communities are configured through SmartConsole GUI. VPN policy installation uses standard policy installation commands. Certificate generation uses certificate management commands and GUI tools. The vpn tu command specifically provides the tunnel testing and troubleshooting capabilities essential for verifying VPN configurations and diagnosing encryption issues.
