Question 2
SmartEvent has several components that function together to track security threats. What is the function of the Correlation Unit as a component of this architecture?
  1. Analyzes each log entry as it arrives at the log server according to the Event Policy. When a threat pattern is identified, an event is forwarded to the SmartEvent Server.
  2. Correlates all the identified threats with the consolidation policy.
  3. Collects syslog data from third party devices and saves them to the database.
  4. Connects with the SmartEvent Client when generating threat reports.
Correct answer: A
Explanation:
The Correlation Unit in SmartEvent architecture has the function of analyzing each log entry as it arrives at the log server according to the Event Policy. When it identifies a threat pattern, it forwards an event to the SmartEvent Server. This is an essential function in threat detection and analysis, as it helps in identifying and alerting about security threats based on the configured policies.Option A correctly describes the function of the Correlation Unit, making it the verified answer.

Question 3
SecureXL improves non-encrypted firewall traffic throughput and encrypted VPN traffic throughput.
  1. This statement is true because SecureXL does improve all traffic.
  2. This statement is false because SecureXL does not improve this traffic but CoreXL does.
  3. This statement is true because SecureXL does improve this traffic.
  4. This statement is false because encrypted traffic cannot be inspected.
Correct answer: C
Explanation:
SecureXL is a performance-enhancing technology used in Check Point firewalls. It improves the throughput of both non-encrypted firewall traffic and encrypted VPN traffic. The statement in option C is true because SecureXL does improve both types of traffic by offloading processing to dedicated hardware acceleration, optimizing firewall and VPN operations.Option C correctly states that SecureXL improves this traffic, making it the verified answer.

Question 5
After making modifications to the $CVPNDIR/conf/cvpnd.C file, how would you restart the daemon?
  1. cvpnd_restart 
  2. cvpnd_restart
  3. cvpnd restart
  4. cvpnrestart
Correct answer: B
Explanation:
The cvpnd_restart command is used to restart the daemon after making modifications to the $CVPNDIR/conf/cvpnd.C file. The cvpnd daemon is responsible for managing the communication between the Check Point components and the Content Vectoring Protocol (CVP) server. The CVP server is an external server that provides content inspection and filtering services for Check Point gateways. The $CVPNDIR/conf/cvpnd.C file contains the configuration settings for the cvpnd daemon, such as the CVP server IP address, port number, timeout value, and debug level.Reference:Check Point Security Expert R81 Course, Content Inspection Using ICAP, cvpnd daemon debug file

Question 6
SandBlast has several functional components that work together to ensure that attacks are prevented in real-time. Which the following is NOT part of the SandBlast component?
  1. Threat Emulation
  2. Mobile Access
  3. Mail Transfer Agent
  4. Threat Cloud
Correct answer: B
Explanation:
Mobile Access is not part of the SandBlast component. Mobile Access is a software blade that provides secure remote access to corporate resources from various devices, such as smartphones, tablets, and laptops. Mobile Access supports different connectivity methods, such as SSL VPN, IPsec VPN, and Mobile Enterprise Application Store (MEAS). Mobile Access also integrates with Mobile Threat Prevention (MTP) to protect mobile devices from malware and network attacks.Reference:Check Point Security Expert R81 Course, Mobile Access Administration Guide, SandBlast Mobile Datasheet

Question 7
With Mobile Access enabled, administrators select the web-based and native applications that can be accessed by remote users and define the actions that users can perform the applications. Mobile Access encrypts all traffic using:
  1. HTTPS for web-based applications and 3DES or RC4 algorithm for native applications. For end users to access the native applications, they need to install the SSL Network Extender.
  2. HTTPS for web-based applications and AES or RSA algorithm for native applications. For end users to access the native application, they need to install the SSL Network Extender.
  3. HTTPS for web-based applications and 3DES or RC4 algorithm for native applications. For end users to access the native applications, no additional software is required.
  4. HTTPS for web-based applications and AES or RSA algorithm for native applications. For end users to access the native application, no additional software is required.
Correct answer: A
Explanation:
Mobile Access encrypts all traffic using HTTPS for web-based applications and 3DES or RC4 algorithm for native applications. For end users to access the native applications, they need to install the SSL Network Extender, which is a lightweight VPN client that creates a secure SSL tunnel to the Mobile Access gateway. The SSL Network Extender supports various types of native applications, such as email clients, file sharing, and remote desktop.Reference:Mobile Access Administration Guide,SSL Network Extender

Question 8
What is the benefit of ''tw monitor'' over ''tcpdump''?
  1. ''fw monitor'' reveals Layer 2 information, while ''tcpdump'' acts at Layer 3. 
  2. ''fw monitor'' is also available for 64-Bit operating systems.
  3. With ''fw monitor'', you can see the inspection points, which cannot be seen in ''tcpdump''
  4. ''fw monitor'' can be used from the CLI of the Management Server to collect information from multiple gateways.
Correct answer: C
Explanation:
The benefit of fw monitor over tcpdump is that with fw monitor, you can see the inspection points, which cannot be seen in tcpdump. Inspection points are the locations in the firewall kernel where packets are inspected by the security policy and other software blades. Fw monitor allows you to capture packets at different inspection points and see how they are processed by the firewall. Tcpdump, on the other hand, is a generic packet capture tool that only shows the packets as they enter or leave the network interface.Reference:Check Point Security Expert R81 Course,fw monitor, tcpdump

Question 9
Which of the following describes how Threat Extraction functions?
  1. Detect threats and provides a detailed report of discovered threats.
  2. Proactively detects threats.
  3. Delivers file with original content.
  4. Delivers PDF versions of original files with active content removed.
Correct answer: D
Explanation:
Threat Extraction is a software blade that delivers PDF versions of original files with active content removed. Active content, such as macros, scripts, or embedded objects, can be used by attackers to deliver malware or exploit vulnerabilities. Threat Extraction removes or sanitizes the active content from the files and converts them to PDF format, which is safer and more compatible. Threat Extraction can also work together with Threat Emulation to provide both clean and original files to the users.Reference:Check Point Security Expert R81 Course, Threat Extraction Administration Guide

Which command gives us a perspective of the number of kernel tables?
  1. fw tab -t
  2. fw tab -s
  3. fw tab -n
  4. fw tab -k
Correct answer: B
Explanation:
The command 'fw tab -s' is used to display information about the state of various kernel tables in a Check Point firewall. It provides a perspective on the number and status of these tables, which can be helpful for troubleshooting and monitoring firewall performance.Option B correctly identifies the command that gives a perspective of the number of kernel tables, making it the verified answer.
