Explanation: The “fw monitor” tool can be best used to troubleshoot network traffic issues. Fw monitor is a tool that allows administrators to capture packets at different inspection points in the Firewall kernel, and apply filters and flags to analyze the traffic. Fw monitor can help troubleshoot network connectivity problems, packet drops, NAT issues, VPN issues, and more. The other options are either not related or less suitable for fw monitor

Explanation: The SandBlast Agent is designed to prevent malware from spreading within the network if it enters an end user’s system. SandBlast Agent is a lightweight endpoint security solution that protects devices from advanced threats such as ransomware, phishing, zero-day attacks, and data exfiltration. SandBlast Agent uses various technologies such as behavioral analysis, anti-exploitation, anti-ransomware, threat emulation, threat extraction, and forensics to detect and block malware before it can harm the device or the network. The other options are either not the main purpose or not the functionality of SandBlast Agent.

Explanation: The statement that is true regarding redundancy is Both ClusterXL and VRRP are fully supported by Gaia and available to all Check Point appliances, open servers, and virtualized environments. ClusterXL and VRRP are two technologies that provide high availability and load sharing for Security Gateways. They are both supported by Gaia OS and can be deployed on various platforms5. The other statements are either false or incomplete regarding redundancy.

Explanation: Sticky Decision Function (SDF) is required to prevent asymmetric routing in an Active-Active cluster. Asymmetric routing occurs when packets from a source to a destination follow a different path than packets from the destination to the source. This can cause problems with stateful inspection and NAT. SDF ensures that packets from the same connection are handled by the same cluster member1.

Explanation: For packets that do not pass Firewall Kernel Inspection and are rejected by the rule definition, packets are dropped with logs and without sending a negative acknowledgment. Firewall Kernel Inspection is the process of applying security policies and rules to network traffic by the Firewall kernel module. If a packet does not match any rule or matches a rule with an action of Drop or Reject, the packet is dropped by the Firewall kernel module. The difference between Drop and Reject is that Drop silently discards the packet without informing the sender, while Reject discards the packet and sends a negative acknowledgment (such as an ICMP message) to the sender. However, both Drop and Reject actions generate logs that record the details of the dropped packets, such as source, destination, protocol, port, rule number, etc. The other options are either incorrect or describe different scenarios.

Explanation: CoreXL is supported when one of the following features is enabled: IPS. CoreXL does not support Check Point Suite with these features: Route-based VPN, IPv6, Overlapping NAT, QoS, Content Awareness, Application Control, URL Filtering, Identity Awareness, HTTPS Inspection, DLP, Anti-Bot, Anti-Virus, Threat Emulation.

Explanation: The fwd process within the Security Management Server is responsible for the receiving of log records from Security Gateway. The fwd process handles the communication with the Security Gateways and log servers via TCP port 2571. The other processes have different roles, such as logd for writing logs to the database, fwm for handling GUI clients, and cpd for infrastructure tasks2.
