CheckPoint 156-587 Exam Dumps

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.''

The Core Dump Manager (CDM) is a utility that helps manage core dump files on Check Point systems. Its main functions include:

Limiting file size and number: CDM can be configured to limit the size of individual core dump files and the total amount of disk space used for core dumps. This prevents core dumps from filling up valuable disk space.

Compression: CDM can compress core dump files to reduce their storage size. This is particularly helpful when dealing with large core dumps.

Process filtering: CDM allows you to specify which processes should be allowed to generate core dumps. This can help prevent unnecessary core dumps from being created.

Remote collection: CDM can be configured to send core dump files to a remote server for analysis. This is useful in environments where direct access to the system generating the core dump is limited.

By using CDM, you can effectively manage core dump files and ensure that they are not overwhelming your system's resources.

The Check Point process responsible for Mobile VPN connections, particularly those associated with the Mobile Access Software Blade (which includes SSL VPN and clientless access), is cvpnd (Connectra VPN Daemon).

Exact Extracts and Supporting Information:

Check Point CLI Reference Guide (for cvpnd_admin):

'cvpnd_admin. Description. Changes the behavior of the Mobile Access cvpnd process.'

This command utility directly interacts with cvpnd for Mobile Access functionalities.

Check Point Daemon Lists (e.g., from 'tech :: stuff - Checkpoint Daemons and Processes Explained' or similar CCTE R81.20 documentation):

Under the 'Mobile Access Blade' section, CVPND is typically listed as:'CVPND - Connectra VPN Daemon. Main daemon for the Mobile Access Software Blade.'

It's also often noted that the cpwd_admin list command (Check Point WatchDog) shows this process as 'CVPND'.

Commands like cvpnstart and cvpnstop are used to manage this daemon.

Exam Preparation Materials (e.g., ExamTopics for 156-586):

A question directly asking 'Which process is responsible for Mobile VPN connections?' with options including cvpnd, vpnk, fwk, and vpnd, typically indicates cvpnd as the correct answer.

Explanation of other options:

B . fwk: This is a general suffix often related to firewall worker processes or kernel modules, not a specific high-level daemon for Mobile VPN.

C . vpnd: This is the main VPN daemon, primarily responsible for site-to-site IPsec VPNs and some traditional IPsec remote access clients. While it handles VPN functions, cvpnd is specialized for Mobile Access.
