質問 # 370
In R81.10 a new feature dynamic log distribution was added. What is this for?
正解：
解説：
Configure the Security Gateway to distribute logs between multiple active Log Servers to support a better rate of Logs and Log Servers redundancy In case of a Management High Availability the management server stores the logs dynamically on the member with the most available disk space in /var/log Synchronize the log between the primary and secondary management server in case of a Management High Availability To save disk space in case of a firewall cluster local logs are distributed between the cluster members.
Explanation
https://resources.checkpoint.com/datasheet/certified-security-expert-ccse-r8120-course-overview Dynamic log distribution is a feature that allows you to configure the Security Gateway to distribute logs between multiple active Log Servers to support a better rate of Logs and Log Servers redundancy. This means that each log is sent to only one Log Server and the load is balanced between the primary Log Servers. If all the primary Log Servers are disconnected, the logs are distributed between the backup Log Servers. If no Log Servers are connected, the gateway writes the logs locally. This feature improves the performance and reliability of logging and reduces the network traffic and disk space consumption. You can enable this feature on the SmartConsole -> Gateways & Servers -> Logs -> Dynamic Log Distribution1.
The other options are incorrect because they do not describe the dynamic log distribution feature. Option B is wrong because the Management High Availability does not store the logs dynamically on the member with the most available disk space, but rather synchronizes the logs between the members using the cpd process2.
Option C is wrong because the dynamic log distribution feature does not synchronize the logs between the primary and secondary management server, but rather distributes the logs between the Log Servers. Option D is wrong because the dynamic log distribution feature does not save disk space in case of a firewall cluster, but rather distributes the logs between the Log Servers. The firewall cluster members do not store local logs, but rather send them to the Log Servers3.

In the Check Point Firewall Kernel Module, each Kernel is associated with a key, which specifies the type of traffic applicable to the chain module. For Wire Mode configuration, chain modules marked with
____________ will not apply.
- A. 0
- B. 1
- C. 2
- D. ffff
正解：B
解説：
Explanation
In the Check Point Firewall Kernel Module, each kernel is associated with a key, which specifies the type of traffic applicable to the chain module. For Wire Mode configuration, chain modules marked with 1 will not apply, as they are related to NAT, VPN, or other features that are not supported in Wire Mode. Wire Mode is a mode of operation that allows transparent traffic forwarding without any inspection or modification by the firewall.

質問 # 373
To fully enable Dynamic Dispatcher on a Security Gateway:
- A. run fw ctl multik set_mode 9 in Expert mode and then Reboot.
- B. Edit/proc/interrupts to include multik set_mode 1 at the bottom of the file, save, and reboot.
- C. run fw multik set_mode 1 in Expert mode and then reboot.
- D. Using cpconfig, update the Dynamic Dispatcher value to "full" under the CoreXL menu.
正解：A
解説：
To fully enable Dynamic Dispatcher on a Security Gateway, you need to run the following command in Expert mode then reboot:
This command sets the multi-core mode to 9, which means that Dynamic Dispatcher is enabled without Firewall Priority Queues. Dynamic Dispatcher is a feature that optimizes the performance of Security Gateways with multiple CPU cores by dynamically allocating traffic to different cores based on their load and priority. Dynamic Dispatcher can improve the throughput and scalability of the Security Gateway, especially for traffic that is not accelerated by SecureXL. The other commands are not valid or do not enable Dynamic Dispatcher. Reference: R81 Performance Tuning Administration Guide
質問 # 374
Which statement is correct about the Sticky Decision Function?
- A. It is automatically disabled if the Mobile Access Software Blade is enabled on the cluster
- B. It is not supported with either the Performance pack of a hardware based accelerator card
- C. It is not required L2TP traffic
- D. Does not support SPI's when configured for Load Sharing
正解：B
解説：
The statement that is correct about the Sticky Decision Function is It is not supported with either the Performance pack of a hardware based accelerator card. The Sticky Decision Function (SDF) is a feature that ensures that packets from the same connection are handled by the same cluster member in a Load Sharing configuration. However, SDF is not compatible with SecureXL acceleration, which is enabled by default or by using a Performance pack or a hardware based accelerator card4. The other statements are either incorrect or outdated about SDF. Reference: Check Point R81 ClusterXL Administration Guide, Sticky Decision Function - Check Point CheckMates
質問 # 375
What information is NOT collected from a Security Gateway in a Cpinfo?
- A. System message logs
- B. Configuration and database files
- C. OS and network statistics
- D. Firewall logs
正解：D
解説：
In a Cpinfo (Checkpoint information) command, various information is collected from a Security Gateway. However, firewall logs are NOT collected from a Security Gateway in a Cpinfo.
A) Firewall logs
The Cpinfo command typically collects information such as configuration and database files, system message logs, OS and network statistics, but it does not include firewall logs. Firewall logs are usually obtained separately using other methods or tools.

質問 # 380
What is the mechanism behind Threat Extraction?
- A. This is a new mechanism which is able to collect malicious files out of any kind of file types to destroy it prior to sending it to the intended recipient.
- B. This is a new mechanism to identify the IP address of the sender of malicious codes and put it into the SAM database (Suspicious Activity Monitoring).
- C. This a new mechanism which extracts malicious files from a document to use it as a counter-attack against its sender.
- D. Any active contents of a document, such as JavaScripts, macros and links will be removed from the document and forwarded to the intended recipient, which makes this solution very fast.
正解：D
解説：
Explanation
Threat Extraction is a technology that removes potentially malicious features that are known to be risky from files (macros, embedded objects and more), rather than determining their maliciousness. By cleaning the file before it enters the organization, Threat Extraction preemptively prevents both known and unknown threats, providing better protection against zero-day attacks1. Any active contents of a document, such as JavaScripts, macros and links will be removed from the document and forwarded to the intended recipient, which makes this solution very fast2. The other options are either incorrect or irrelevant to the mechanism behind Threat Extraction.

質問 # 381
The ____ software blade package uses CPU-level and OS-level sandboxing in order to detect and block malware.
- A. Next Generation Firewall
- B. Next Generation Threat Prevention
- C. Next Generation Threat Extraction
- D. Next Generation Threat Emulation
正解：D
解説：
The software blade package that uses CPU-level and OS-level sandboxing in order to detect and block malware is the Next Generation Threat Emulation. This package is part of the Check Point SandBlast Zero-Day Protection solution, which protects organizations against unknown malware, zero-day threats and targeted attacks, and prevents infections from undiscovered exploits1.
CPU-level and OS-level sandboxing are two techniques that Check Point uses to analyze files and objects for malicious behavior. CPU-level inspection is a unique technology that detects malware at the pre-infection stage by examining the CPU instructions that the file executes. This allows Check Point to identify and block malware that tries to evade detection by using obfuscation, encryption, or polymorphism12.
OS-level sandboxing is a complementary technology that runs files and objects in a virtualized environment and monitors their behavior for malicious indicators. This allows Check Point to detect and block malware that tries to exploit vulnerabilities in the operating system or applications, or that performs malicious actions such as downloading additional payloads, modifying system settings, or communicating with command and control servers12.
Therefore, the correct answer is B) The Next Generation Threat Emulation software blade package uses CPU-level and OS-level sandboxing in order to detect and block malware.

質問 # 382
How can you switch the active log file?
- A. Run fw logswitch on the gateway
- B. Run fwm logswitch on the Management Server
- C. Run fw logswitch on the Management Server
- D. Run fwm logswitch on the gateway
正解：C
解説：
Explanation
You can switch the active log file by running fw logswitch on the Management Server1. This command closes the current log file and creates a new one2. It is useful for archiving or backing up log files, or for creating a new log file for a specific time period2. You can also schedule the log switch to occur automatically at a regular interval, such as daily, weekly, or monthly2. To run this command, you need to access the Management Server in expert mode and run fw logswitch1. You can also use the SmartView Tracker to switch the active log file from the GUI. To do this, go to the Network & Endpoint tab, click on the File menu, and select Switch Active File...3.

質問 # 386
What is the main difference between Threat Extraction and Threat Emulation?
- A. Threat Emulation never delivers a file that takes less than a second to complete.
- B. Threat Emulation never delivers a file and takes more than 3 minutes to complete.
- C. Threat Extraction always delivers a file and takes less than a second to complete.
- D. Threat Extraction never delivers a file and takes more than 3 minutes to complete.
正解：C
解説：
Threat Extraction (Answer B): Threat Extraction always delivers a file, but it removes potentially malicious content from the file before delivering it to the user. It is designed to provide a safe version of the file quickly, taking less than a second to complete.
Threat Emulation (Option A): Threat Emulation does not deliver the original file to the user until it has been thoroughly analyzed for threats. It may take more than 3 minutes to complete the analysis. The emphasis here is on safety and thorough inspection, which may result in a longer processing time.
Therefore, Option B correctly describes the main difference between Threat Extraction and Threat Emulation.

質問 # 389
An established connection is going to www.google.com. The Application Control Blade Is inspecting the traffic. If SecureXL and CoreXL are both enabled, which path is handling the traffic?
- A. Accelerated Path
- B. Medium Path
- C. Fast Path
- D. Slow Path
正解：A
解説：
The traffic is handled by the Accelerated Path. According to the R81.x Security Gateway Architecture (Logical Packet Flow)1, the Accelerated Path is the fastest path for processing packets, as it bypasses most of the inspection and uses SecureXL to accelerate the traffic. The Accelerated Path is used for connections that are established, compliant with the security policy, and do not require any content inspection or NAT1.
The Application Control blade inspects the traffic based on the application identity, which is determined by the Application Control Software Blade in the Medium Path1. However, once the application identity is established, the connection can be offloaded to SecureXL and handled by the Accelerated Path2. This way, the Application Control blade can improve performance and reduce CPU consumption2.
The other paths are not used for this traffic because:
The Slow Path is used for packets that are not compliant with the security policy, require stateful inspection or NAT, or are not supported by SecureXL1. This path involves the most inspection and processing, and is therefore the slowest3.
The Fast Path is used for packets that are trusted and do not require any inspection or NAT. This path bypasses both SecureXL and the Firewall kernel, and uses a kernel module called simfast to forward the packets directly to the network interface driver4. This path is not enabled by default, and requires manual configuration of rules to define which traffic can use it4.
The Medium Path is used for packets that require content inspection, such as IPS, Anti-Virus, Anti-Bot, URL Filtering, or Application Control1. This path uses SecureXL to accelerate some parts of the inspection, but still involves some processing by the Firewall kernel3. This path is only used for the first few packets of a connection until the application identity is established, and then the connection can be offloaded to the Accelerated Path2.
質問 # 390
Bob has finished io setup provisioning a secondary security management server. Now he wants to check if the provisioning has been correct. Which of the following Check Point command can be used to check if the security management server has been installed as a primary or a secondary security management server?
- A. cpprod_util MgmtlsSecondary
- B. cpprod_util MgmtlsPrimary
- C. cpprod_util FwlsPrimary
- D. cpprod_util FwlsSecondary
正解：B
解説：
The cpprod_util command is a utility that provides information about the installed Check Point products and their versions. The cpprod_util MgmtIsPrimary option checks if the Security Management Server is installed as a primary or a secondary server in a High Availability cluster2. If the server is primary, the command returns "yes". If the server is secondary, the command returns "no". Therefore, Bob can use this command to verify the provisioning of the secondary Security Management Server.
質問 # 391
What command lists all interfaces using Multi-Queue?
- A. show interface all
- B. cpmq get
- C. cpmq set
- D. show multiqueue all
正解：B
解説：
Explanation
The command that lists all interfaces using Multi-Queue is cpmq get. Multi-Queue is a feature that allows network interfaces to use multiple transmit and receive queues, which improves the performance and scalability of the Security Gateway by distributing the network load among several CPU cores. Cpmq is a command that allows administrators to configure and manage Multi-Queue settings on network interfaces.
Cpmq get lists all interfaces using Multi-Queue and shows their queue count and core distribution.
質問 # 392
What is a feature that enables VPN connections to successfully maintain a private and secure VPN session without employing Stateful Inspection?
- A. Stateful Mode
- B. VPN Routing Mode
- C. Wire Mode
- D. Stateless Mode
正解：C
解説：
Wire Mode is a VPN-1 NGX feature that enables VPN connections to successfully fail over, bypassing Security Gateway enforcement. This improves performance and reduces downtime. Based on a trusted source and destination, Wire Mode uses internal interfaces and VPN Communities to maintain a private and secure VPN session, without employing Stateful Inspection. Since Stateful Inspection no longer takes place, dynamic-routing protocols that do not survive state verification in non-Wire Mode configurations can now be deployed. The VPN connection is no different from any other connections along a dedicated wire, thus the meaning of "Wire Mode".
