Free Checkpoint 156-587 Practice Exam with Questions & Answers

To troubleshoot Identity Awareness issues related to user identification and Access Role application, you need to enable debugging for both Identity Collectors (IDC) and Identity Providers (IDP). The command pdp debug set IDC all IDP all on the gateway achieves this.

Here's why this is the correct answer and why the others are not:

A. on the gateway: pdp debug set IDC all IDP all:This correctly enables debugging for all Identity Collectors and Identity Providers, allowing you to see detailed logs and messages related to user identification and Access Role assignment. This helps pinpoint issues with user mapping, authentication, or authorization.

B. on the gateway: pdp debug set AD all and IDC all:This command only enables debugging for Active Directory (AD) as an Identity Provider and all Identity Collectors. It might miss issues related to other Identity Providers if they are in use.

C. on the management: pdp debug on IDC all:This command has two issues. First, it should be executed on the gateway, not the management server, as the gateway is responsible for user identification and policy enforcement. Second, it only enables debugging for Identity Collectors, not Identity Providers.

D. on the management: pdp debug set all:While this command might seem to enable debugging for everything, it's not specific enough for Identity Awareness troubleshooting. It might generate excessive logs unrelated to the issue and make it harder to find the relevant information.

 The top command is a Linux command that displays information about resource utilization for running processes and shows additional information for core utilization and memory. The top command provides a dynamic real-time view of the system, showing the processes that are consuming the most CPU, memory, and other resources. The top command also shows the total number of processes, the system load average, the uptime, and the CPU usage by user, system, andidle. The top command can be customized by using various options and interactive commands to change the display, sort the processes, filter the output, and kill processes.

The other commands are incorrect because:

B. vmstat is a Linux command that displays information about the virtual memory, CPU, disk, and system activity. It does not show information about individual processes or core utilization.

C. cptop is a Check Point command that displays information about the firewall kernel activity, such as the number of connections, packets, drops, and rejects. It does not show information about other processes or memory usage.

D. mpstat is a Linux command that displays information about the CPU utilization by each processor or core. It does not show information about processes or memory usage.

The simplest and most efficient way to check all dropped packets in real time is C. fw ctl zdebug + drop in expert mode. This command is a shortcut command that sets the kernel debug flags to a predefined value and prints the debug output to the standard output. It is useful for general debugging of common issues, such as traffic drops, NAT, VPN, or clustering. It has a small buffer size and does not require additional steps to start or stop the debugging. However, it has some limitations, such as it cannot be used with SecureXL, it cannot filter the output by chain modules, and it cannot save the output to a file12.

The other commands are not as simple or efficient as the fw ctl zdebug + drop command. The command tail -f $FWDIR/log/fw.log |grep drop in expert mode will only show the drops that are logged in the fw.log file, which may not include all the drops that occur in the kernel. The command cat /dev/fw1/log in expert mode will show the raw binary data of the kernel debug buffer, which is not human-readable and may contain irrelevant information. The command Smartlog will show the drops that are indexed and stored in the SmartEvent database, which may not be in real time and may depend on the log server performance12.

The Check Point R81.20 Gaia Administration Guide describes fw ctl zdebug as a key troubleshooting tool for real-time packet analysis, particularly for drops. The CCTE R81.20 course emphasizes using fw ctl zdebug for kernel-level debugging, including monitoring dropped packets.

For precise details, refer to:

Check Point R81.20 Gaia Administration Guide, section on “fw ctl zdebug” (available via Check Point Support Center).

CCTE R81.20 Courseware, which covers advanced troubleshooting techniques for packet drops (available through authorized training partners).

When a process isfrozen(hung or unresponsive), the typical method to resolve it is tokill the process. On Check Point, you can use cpwd_admin kill -name or a standard Linux kill -9 command if necessary. You then allowCPWD(the Check Point watchdog) to restart it, or manually restart it if needed.

Other options:

A. Power off the machine: This is too drastic and not recommended just for a single frozen process.

B. Restart the process: While this sounds viable, you typicallymust killthe frozen process first, then let WatchDog or an admin restart it.

C. Reboot the machine: Similar to powering off—too disruptive for just one stuck process.

Hence, the most direct and standard approach:

“Kill the process.”

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.

If you have modified kernel parameters (infwkern.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.”
