Free Practice Questions for Checkpoint 156-315.81 Exam

With SecureXL enabled, accelerated packets will pass through the following: Network Interface Card and the Acceleration Device. SecureXL is a technology that accelerates network traffic processing by offloading intensive operations from the Firewall kernel to a dedicated SecureXL device. Accelerated packets are packets that match certain criteria and can be handled by SecureXL without involving the Firewall kernel. These packets bypass the OSI Network Layer, OS IP Stack, and Check Point Firewall Kernel, and are processed directly by the Network Interface Card and the Acceleration Device. The other options are either incorrect or describe non-accelerated packets. 

The methods of SandBlast Threat Emulation deployment are Cloud, Appliance, and Private. SandBlast Threat Emulation is a solution that detects and prevents zero-day attacks by emulating files in a sandbox environment and analyzing their behavior for malicious indicators. SandBlast Threat Emulation can be deployed in three different methods: Cloud, Appliance, and Private. Cloud method is when the files are sent to the Check Point cloud service for emulation and analysis. This method does not require any additional hardware or software on the customer’s side, and provides the fastest updates and feeds from ThreatCloud. Appliance method is when the files are sent to a dedicated appliance on the customer’s network for emulation and analysis. This method provides more control and privacy for the customer, and supports more file types and sizes. Private method is when the files are sent to a private cloud service on the customer’s network for emulation and analysis. This method provides the highest level of control and privacy for the customer, and supports customizing the emulation environment and scenarios.

According to the Check Point website, INSPECT Engine is the technology that extracts detailed information from packets and stores that information in state tables. INSPECT Engine is the core of Check Point’s Stateful Inspection technology, which enables Security Gateways to inspect traffic at multiple layers and enforce security policies. The other technologies are either not related or not specific enough. References: INSPECT Engine

 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 number of cores that can be used in a Cluster for Firewall-kernel on the new device with 4 cores is 4. Cluster is a feature that allows two or more Security Gateways to provide high availability and load balancing for network traffic. Firewall-kernel is a component of the Security Gateway that performs packet inspection according to security policies. The number of cores that can be used for Firewall-kernel in a Cluster depends on the number of cores available on each device in the Cluster. The Cluster will use the lowest common denominator of cores among all devices in the Cluster for Firewall-kernel. Therefore, if one device has 2 cores and another device has 4 cores, the Cluster will use 2 cores for Firewall-kernel on each device. However, if both devices have 4 cores, the Cluster will use 4 cores for Firewall-kernel on each device.

 When SecureXL is enabled, all packets should be accelerated, except packets that match the following conditions: CIFS packets. SecureXL is a technology that accelerates network traffic processing by offloading intensive operations from the Firewall kernel to a dedicated SecureXL device. However, some packets cannot be accelerated by SecureXL due to various reasons, such as unsupported features, security policy settings, or protocol limitations. One example of packets that cannot be accelerated by SecureXL are CIFS packets, which are used for file sharing and access over SMB protocol. CIFS packets are not accelerated by SecureXL because they require stateful inspection by the Firewall kernel. 

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.

 SmartEvent automatically defines events based on IPS (Intrusion Prevention System) alerts. IPS is a feature that detects and prevents malicious network traffic based on predefined or custom signatures. IPS alerts are generated when IPS detects an attack or an anomaly that matches a signature. SmartEvent collects and correlates IPS alerts from different gateways and displays them as events in SmartEventWeb. The other options are not automatically defined as events by SmartEvent. 

 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

 According to the Check Point R81 training course, the medium path is available only when CoreXL is enabled. CoreXL is a performance-enhancing technology that allows multiple CPU cores to process traffic simultaneously. The medium path handles packets that require deeper inspection or content awareness, such as IPS, Anti-Virus, or URL Filtering. The other paths are either available regardless of CoreXL or not valid terms. References: Certified Security Expert (CCSE) R81.20 Course Overview

Check Point APIs let system administrators and developers make changes to the security policy with CLI tools and web-services. You can use an API to:

• Use an automated script to perform common tasks

• Integrate Check Point products with 3rd party solutions

• Create products that use and enhance the Check Point solution

According to the Check Point R81 training course, the Proxy ARP feature for Manual NAT in R81.20 requires the configuration of the local.arp file on the Security Gateway. This file contains the mapping of IP addresses to MAC addresses for NATed hosts. The other options are either incorrect or irrelevant.

The command to show SecureXL status is fwaccel stat. This command displays information about SecureXL acceleration, such as the number of accelerated and non-accelerated connections, the reason for non-acceleration, and the SecureXL device name and mode. The other commands are either invalid or show different statistics.

One of the major features in R81 SmartConsole is concurrent administration. This feature allows multiple administrators to work on the same Security Policy simultaneously, without blocking each other or creating conflicts. Concurrent administration improves the efficiency and productivity of security management operations1.

However, not all of the options given are possible considering that AdminA, AdminB and AdminC are editing the same Security Policy. The correct answer is B. AdminA and AdminB are editing the same rule at the same time. This is not possible because concurrent administration uses a locking mechanism to prevent multiple administrators from modifying the same rule or object at the same time. When an administrator clicks on a rule or an object, it becomes locked and a lock icon appears next to it. The lock icon shows the name of the administrator who is working on that rule or object, and prevents other administrators from editing it until it is unlocked12.

Therefore, the other options are possible considering that AdminA, AdminB and AdminC are editing the same Security Policy. Option A is possible because a lock icon shows that a rule or an object is locked and will be available when the administrator who locked it finishes working on it or logs out of SmartConsole12. Option C is possible because a lock icon next to a rule informs that any administrator is working on this particular rule, and hovering over the lock icon will show the name of that administrator12. Option D is possible because AdminA, AdminB and AdminC are editing three different rules at the same time, which does not create any conflicts or blockages12.

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.
