 For Stateful Mode configuration, chain modules marked with 2 will not apply. Stateful Mode configuration is a feature that allows administrators to define how packets are processed by different firewall kernel modules in inbound and outbound directions. Chain modules are firewall kernel modules that perform various security functions, such as VPN, IPS, QoS, etc. Each chain module is associated with a key, which specifies the type of traffic applicable to the chain module. The key can be one of the following values: 0 for all packets, 1 for stateful packets, 2 for stateless packets, and 3 for no match packets. For Stateful Mode configuration, only chain modules with key 0 or 1 will apply, as they handle all packets or stateful packets. Chain modules with key 2 will not apply, as they handle stateless packets, which are not relevant for Stateful Mode configuration.

 If Deyra sees the gateway status as shown in the image, it means that there is a blade reporting a problem. The red exclamation mark indicates that one or more blades on the gateway have an issue that needs attention. The issue could be related to configuration, license, policy, or other factors. Deyra can hover over the icon to see more details about the problem. References: Training & Certification | Check Point Software, New Courses and Certificates for R81.20 - Check Point CheckMates

SmartEvent Unit is not a blade option when configuring SmartEvent. SmartEvent is a unified security event management solution that provides visibility, analysis, and reporting of security events across multiple Check Point products. SmartEvent consists of three main components: SmartEvent Server, Correlation Unit, and Log Server. SmartEvent Server is responsible for storing and displaying security events in SmartConsole and SmartEventWeb. Correlation Unit is responsible for collecting and correlating logs from various sources and generating security events based on predefined or custom scenarios. Log Server is responsible for receiving and indexing logs from Security Gateways and other Check Point modules. SmartEvent Unit is not a valid component or blade of SmartEvent.

A star community is a VPN topology where one or more satellites connect to a center gateway. The center gateway can be a Security Gateway or a Security Management Server. The VPN routing option determines how the traffic is routed between the satellites and the center, and between the satellites themselves. There are three VPN routing options available in a star community12:

To center only: The satellites can only communicate with the center gateway, and not with each other or with any other VPN targets. This option is useful for remote access clients that only need to access resources on the center gateway.

To center, or through the center to other satellites, to Internet and other VPN targets: The satellites can communicate with the center gateway, and also with other satellites, Internet hosts, and other VPN targets through the center gateway. This option is useful for branch offices that need to access resources on the center gateway, as well as on other branch offices, Internet hosts, and other VPN targets.

To center and to other satellites through center: The satellites can communicate with the center gateway, and also with other satellites through the center gateway. However, they cannot communicate with Internet hosts or other VPN targets. This option is useful for branch offices that need to access resources on the center gateway and on other branch offices, but not on Internet hosts or other VPN targets.

Therefore, the options A (To satellites through center only) and D (To center only) are not valid VPN routing options in a star community.

The option that is NOT an option to calculate the traffic direction is Outgoing. Traffic direction is a parameter that determines how traffic is classified as internal or external based on its source and destination. Traffic direction can be calculated using three options: Incoming, Internal, or External. Incoming means that traffic is classified as internal if its destination is one of the Security Gateway’s interfaces, and external otherwise. Internal means that traffic is classified as internal if its source or destination belongs to one of the internal networks defined in the topology, and external otherwise. External means that traffic is classified as internal if both its source and destination belong to one of the internal networks defined in the topology, and external otherwise. Outgoing is not a valid option to calculate traffic direction. 

The default commands that appear when right-clicking the IP address, source or destination, in an event in SmartEvent are ping, whois, nslookup, and Telnet. SmartEvent is a unified security event management solution that provides visibility, analysis, and reporting of security events across multiple Check Point products. SmartEvent has a feature that allows administrators to run common command line executables that can assist in investigating events. Right-clicking the IP address, source or destination, in an event provides a list of default and customized commands that can be executed on the IP address of the active cell. The default commands are ping, whois, nslookup, and Telnet. Ping is a command that tests the connectivity and latency between two hosts by sending packets and measuring the response time. Whois is a command that queries a database for information about the owner and registrar of a domain name or an IP address. Nslookup is a command that queries a DNS server for information about a domain name or an IP address, such as its IP address, name server, mail server, etc. Telnet is a command that establishes a remote connection to another host using the Telnet protocol. 

ThreatCloud is a collaboration platform for all the Check Point customers to share information about malicious and benign files that all of the customers can benefit from as it makes emulation of known files unnecessary. ThreatCloud is a cloud-based service that collects and analyzes threat intelligence from multiple sources, such as Check Point products, third-party vendors, open sources, and customers. ThreatCloud provides real-time updates and feeds to Check Point products, such as SandBlast, which is a solution that detects and prevents zero-day attacks by emulating files in a sandbox environment. By integrating with ThreatCloud, a Threat Emulation appliance can benefit from the shared information about malicious and benign files, and avoid emulating files that are already known to be safe or harmful. This can improve the performance and efficiency of the Threat Emulation appliance. The other options are either incorrect or not relevant to ThreatCloud or Threat Emulation. 

AppWiki is the Check Point feature that enables application scanning and the detection. AppWiki is an easy to use tool that lets you search and filter Check Point’s Web 2.0 Applications Database to find out information about internet applications, including social network widgets; filter by a category, tag, or risk level; and search for a keyword or application1. AppWiki helps you to identify and control the applications on your network, and to apply granular policies based on the application type, risk, and characteristics1. AppWiki is integrated with the Check Point Application Control Software Blade, which provides the industry’s strongest application security and identity control to organizations of all sizes1.

 The most ideal Synchronization Status for Security Management Server High Availability deployment is Synchronized. Security Management Server High Availability deployment is a feature that allows two or more Security Management Servers to provide redundancy and load balancing for managing security policies and logs. Synchronization Status is a parameter that indicates how up-to-date the databases of the Security Management Servers are with each other. Synchronization Status can have one of the following values: Synchronized, Lagging, Never been synchronized, or Collision. Synchronized means that the databases of all Security Management Servers are identical and have no conflicts. This is the most ideal status as it ensures consistency and reliability of security management. Lagging means that one or more Security Management Servers have not received all the updates from other Security Management Servers, and their databases are outdated. Never been synchronized means that one or more Security Management Servers have never synchronized their databases with other Security Management Servers, and their databases are independent. Collision means that one or more Security Management Servers have received conflicting updates from other Security Management Servers, and their databases have discrepancies. 

To change the number of firewall instances used by CoreXL, the cpconfig command must be used, followed by a reboot. CoreXL is a technology that improves the performance of the Security Gateway by using multiple cores to handle concurrent connections. The number of firewall instances determines how many cores are dedicated to CoreXL. The cpconfig command allows the administrator to configure various settings on the Security Gateway, including the number of firewall instances. After changing this setting, a reboot is required for the changes to take effect. The other commands are either incorrect or do not require a reboot.

Check Point security components are divided into the following components: GUI Client, Security Management, Security Gateway. GUI Client is the graphical user interface that allows administrators to configure, manage, and monitor Check Point products and security policies. Security Management is the server that stores and enforces the security policies and provides logging and reporting functions. Security Gateway is the device that inspects and filters network traffic according to the security policies. 

After trust has been established between the Check Point components, the Security Gateway IP address cannot be changed without re-establishing the trust. This is because the trust is based on the Secure Internal Communication (SIC) mechanism, which uses certificates to authenticate and encrypt the communication. The certificates are issued by the Internal Certificate Authority (ICA) of the Security Management Server / Domain Management Server, and contain the name and IP address of the component. Therefore, if the IP address of a component is changed, the certificate will become invalid and the trust will be lost. To restore the trust, the certificate must be renewed or reissued by the ICA12.

However, there are some exceptions to this rule. The Security Gateway name can be changed in command line without re-establishing trust, as long as the IP address remains the same. This is because the SIC mechanism does not rely on the hostname, but on the IP address and the SIC name (which is usually derived from the hostname, but can be manually changed). The Security Management Server name can be changed in SmartConsole without re-establishing trust, as long as the IP address remains the same. This is because SmartConsole uses a different mechanism to connect to the Security Management Server, which does not depend on the SIC certificate. The Security Management Server IP address can be changed without re-establishing trust, as long as some steps are followed to update the Check Point Registry file on the managed Security Gateways / Cluster Members / VSX Virtual Devices. This is because the Registry file contains the IP address of the ICA, which is used for certificate renewal. If the Registry file is not updated, then the certificate renewal will fail and the trust will be lost3.

 According to the Check Point R81 Mobile Access Administration Guide, the recommended number of physical network interfaces in a Mobile Access cluster deployment is three. One interface should be connected to the organization network, one interface should be connected to the Internet, and one interface should be used for synchronization between cluster members. This configuration provides optimal performance and security for Mobile Access traffic. 

The tool that is used to enable ClusterXL is cpconfig. ClusterXL is a software-based Load Sharing and High Availability solution that distributes network traffic between clusters of redundant Security Gateways1. ClusterXL can be enabled on Check Point Security Gateways running on Gaia OS, SecurePlatform OS, IPSO OS, or X-Series XOS2.

To enable ClusterXL, the administrator must run the cpconfig command on each cluster member and select the option to enable ClusterXL. This will prompt the administrator to choose the ClusterXL mode (High Availability or Load Sharing) and the Cluster Control Protocol (CCP) mode (Broadcast or Multicast). After enabling ClusterXL, the administrator must reboot the cluster members for the changes to take effect34.

Therefore, the correct answer is B. The tool that is used to enable ClusterXL is cpconfig.
