Other certification materials providers often include outdated or removed questions by CheckPoint in their CheckPoint 156-587 exam. These outdated questions lead to customers failing their CheckPoint Check Point Certified Troubleshooting Expert - R81.20 exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the CheckPoint 156-587 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
You need to monitor traffic pre-inbound and before the VPN module in a Security Gateway. How would you achieve this using fw monitor?
The fw monitor command is a powerful troubleshooting tool in Check Point Gateways that captures packets at various points in the processing chain. The question asks how to capture traffic pre-inbound (before inbound processing, i.e., at the ''i'' inspection point) and before the VPN module (before VPN decryption or processing).
The fw monitor syntax allows specifying inspection points using options like -pi (pre-inbound) and module names (e.g., -vpn for the VPN module). The correct syntax to capture traffic before a specific module is -pi -<module>, where the module name is prefixed with a minus sign to indicate ''before'' the module.
Option A: Incorrect. fw monitor -p all captures packets at all inspection points in the chain, which includes pre-inbound, post-inbound, pre-outbound, and post-outbound points, as well as points around all modules. This is too broad and does not specifically target pre-inbound and before the VPN module.
Option B: Correct. fw monitor -pi -vpn captures packets at the pre-inbound inspection point (''i'') and before the VPN module (-vpn). The -pi specifies the pre-inbound point, and -vpn ensures the capture occurs before VPN processing (e.g., decryption).
Option C: Incorrect. fw monitor -pi +vpn would capture packets at the pre-inbound point but after the VPN module (+vpn indicates after the module), which contradicts the requirement to capture before the VPN module.
Option D: Incorrect. This option is a duplicate of Option C in the provided question, likely a typographical error. Even if corrected, +vpn is incorrect for the same reason as Option C.
The Check Point R81.20 Gaia Administration Guide explains the fw monitor command and its options, including how to specify inspection points and module positions. The CCTE R81.20 course includes hands-on labs for using fw monitor to troubleshoot packet flow, emphasizing precise inspection point selection.
For precise details, refer to:
Check Point R81.20 Gaia Administration Guide, section on ''fw monitor'' (available via Check Point Support Center).
CCTE R81.20 Courseware, which covers advanced packet capture techniques with fw monitor (available through authorized training partners).
Which process is responsible for the generation of certificates?
The cpca process is responsible for the generation of certificates on the Security Management Server or the Multi-Domain Security Management Server. It is the Check Point Internal Certificate Authority (ICA) that issues certificates for internal use, such as for VPN, HTTPS Inspection, SmartConsole, and Secure Internal Communication (SIC). The cpca process runs on the Security Management Server or the Multi-Domain Security Management Server as part of the Management High Availability module.

Where do you enable log indexing on the SMS?
What is the Security Gateway directory where an administrator can find vpn debug log files generated during Site-to-Site VPN troubleshooting?
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.
