NEW QUESTION # 83
URL Filtering is an essential part of Web Security in the Gateway. For the Security Gateway to perform a URL lookup when a client makes a URL request, where is the sync-request forwarded from if a sync-request is required?

  • A. URLF Online Service
  • B. RAD User Space
  • C. RAD Kernel Space
  • D. URLF Kernel Client

Answer: D

Explanation:
URL Filtering is an essential part of Web Security in the Gateway that allows the administrator to control the access to web sites based on the site categorization and reputation. For the Security Gateway to perform a URL lookup when a client makes a URL request, the following steps are involved12:
* The URLF Kernel Client is the component that intercepts the URL request from the client and extracts the URL information, such as the host name, the path, and the query parameters. The URLF Kernel Client then checks the local cache to see if the URL has been previously categorized. If the URL is found in the cache, the URLF Kernel Client returns the cached category to the Security Policy and enforces the relevant action. If the URL is not found in the cache, the URLF Kernel Client sends a sync- request to the URLF User Space.
* The URLF User Space is the component that handles the sync-request from the URLF Kernel Client and performs the URL lookup. The URLF User Space first checks the local database to see if the URL has been previously categorized. If the URL is found in the database, the URLF User Space returns the database category to the URLF Kernel Client. If the URL is not found in the database, the URLF User Space sends an async-request to the URLF Online Service.
* The URLF Online Service is the component that handles the async-request from the URLF User Space and performs the URL lookup. The URLF Online Service is a cloud-based service that provides the most updated and accurate URL categorization and reputation. The URLF Online Service queries the Check Point cloud servers to get the category and reputation of the URL, and returns the result to the URLF User Space. The URLF Online Service also updates the local database and cache with the new URL information.
Therefore, the sync-request is forwarded from the URLF Kernel Client to the URLF User Space, if a sync- request is required.

NEW QUESTION # 84
When a User Mode process suddenly crashes, it may create a core dump file. Which of the following information is available in the core dump and may be used to identify the root cause of the crash?
i. Program Counter
ii. Stack Pointer
iii. Memory management information
iv. Other Processor and OS flags / information

  • A. Only lii
  • B. iii and iv only
  • C. i and ii only
  • D. i, ii, iii and iv

Answer: D

Explanation:
A core dump file is essentially a snapshot of the process's memory at the time of the crash. This snapshot includes crucial information that can help diagnose the cause of the crash. Here's why all the options are relevant:
* i. Program Counter: This register stores the address of the next instruction the CPU was supposed to execute. It pinpoints exactly where in the code the crash occurred.
* ii. Stack Pointer: This register points to the top of the call stack, which shows the sequence of function calls that led to the crash. This helps trace the program's execution flow before the crash.
* iii. Memory management information: This includes details about the process's memory allocations, which can reveal issues like memory leaks or invalid memory access attempts.
* iv. Other Processor and OS flags/information: This encompasses various registers and system information that provide context about the state of the processor and operating system at the time of the crash.
By analyzing this information within the core dump, you can often identify the root cause of the crash, such as a segmentation fault, null pointer dereference, or stack overflow.
Check Point Troubleshooting References:
While core dumps are a general concept in operating systems, Check Point's documentation touches upon them in the context of troubleshooting specific processes like fwd (firewall) or cpd (Check Point daemon).
The fw ctl zdebug command, for example, can be used to trigger a core dump of the fwd process for debugging purposes.


NEW QUESTION # 85
When viewing data for CPMI objects in the Postgres database, what table column should be selected to query for the object instance?

  • A. fwset
  • B. CpmiHostCkp
  • C. CPM Global M
  • D. GuiDBedit

Answer: B

Explanation:
The CpmiHostCkp table in the Postgres database contains the data for CPMI objects, such as gateways, clusters, and servers. The table column that should be selected to query for the object instance is the objid column, which is the primary key of the table and uniquely identifies each object. The objid column can be used to join with other tables that reference CPMI objects, such as CpmiClusterMember, CpmiCluster, and CpmiServer. The objid column can also be used to retrieve the object name, IP address, type, and other attributes from the CpmiHostCkp table itself. References:

  • A. Use "fw ctl zdebug" because of 1024KB buffer size
  • B. Reduce debug buffer to 1024KB and run debug for several times

NEW QUESTION # 87
What is the Security Gateway directory where an administrator can find vpn debug log files generated during Site-to-Site VPN troubleshooting?

  • A. SFWDIR/conf/
  • B. SFWDIR/log/
  • C. SCPDIR/conf/
  • D. opt/CPsuiteR80/vpn/log/

Answer: B

Explanation:
The correct directory where an administrator can find vpn debug log files generated during Site-to-Site VPN troubleshooting is $FWDIR/log/. This directory contains the following files related to vpn debug:
* vpnd.elg: This file contains the high-level VPN debug information, such as the VPN tunnel establishment, deletion, and negotiation messages. It can be enabled by using the vpn debug on command on the Security Gateway CLI.
* legacy_ike.elg: This file contains the low-level IKE debug information for IKEv1, such as the IKE packets, encryption, decryption, and authentication. It can be enabled by using the vpn debug ikeon command on the Security Gateway CLI.
* legacy_ikev2.xml: This file contains the low-level IKE debug information for IKEv2, such as the IKE packets, encryption, decryption, and authentication. It can be enabled by using the vpn debug ikev2on command on the Security Gateway CLI.
These files can be viewed by using the vpn debug view command on the Security Gateway CLI, or by using the IKEView tool on the Security Management Server GUI.
