NEW QUESTION # 68
What is the Security Gateway directory where an administrator can find vpn debug log files generated during Site-to-Site VPN troubleshooting?

Answer: C

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.

NEW QUESTION # 69
Your users are having trouble opening a Web page and you need to troubleshoot it. You open the Smart Console, and you get the following message when you navigate to the Logs and Monitor "SmartLog is not active or Failed to parse results from server". What is the first thing you can try to resolve it?

Answer: C

Explanation:
The error message "SmartLog is not active or Failed to parse results from server" indicates that there is a problem with the SmartLog server process, which is responsible for indexing and querying the logs. One possible cause of this problem is a corrupted log file or a mismatched IP address in the logging configuration files. Another possible cause is a communication failure between the SmartLog server and the CPM process or the SmartConsole client. To resolve this issue, the first thing to try is to restart the SmartLog server process by running the command smartlog_server restart on the Security Management Server or the Log Server. This command will stop the SmartLog server, clean the buffer, and start it again. This may fix the corrupted log file or the communication issue. If the problem persists, other steps may be needed, such as checking the network connectivity, the firewall rules, the logging configuration files, the CPM process, or the SmartConsole client.

NEW QUESTION # 70
Which of these packet processing components stores Rule Base matching state-related information?

Answer: C


NEW QUESTION # 71
You modified kernel parameters and after rebooting the gateway, a lot of production traffic gets dropped and the gateway acts strangely What should you do"?

Answer: D

Explanation:
If you have modified kernel parameters (in fwkern.conf, for example) and the gateway starts dropping traffic or behaving abnormally after a reboot, the best practice is to restore the original or a known-good configuration from backup. Then, reboot again so that the gateway loads the last known stable settings.
Option A (fw ctl set int fw1_kernel_all_disable=1) is not a standard or documented method for "undoing" all kernel tweaks.
Option B (Restore fwkem.conf from backup and reboot the gateway) is the correct and straightforward approach.
Option C (fw unloadlocal) removes the local policy but does not revert custom kernel parameters that have already been loaded at boot.
Option D (Remove all kernel parameters from fwkem.conf and reboot) might help in some cases, but you risk losing other beneficial or necessary parameters if there were legitimate custom settings. Restoring from a known-good backup is safer and more precise.
Hence, the best answer:
"Restore fwkem.conf from backup and reboot the gateway."

NEW QUESTION # 72
What is correct about the Resource Advisor (RAD) service on the Security Gateways?

Answer: A

Explanation:
The Resource Advisor (RAD) service on the Security Gateways is responsible for online categorization of URLs and resources for Application Control and Threat Prevention blades. RAD has two components: a kernel module and a user space module. The kernel module looks up the kernel cache for URLs and resources, notifies the client about hits and misses, and forwards asynchronous requests to the user space module. The user space module handles the communication with the Check Point online web service and updates the kernel cache with the results. RAD can operate in three modes: hold, background, and custom, depending on the configuration of the blades and the policy. References:
