Checkpoint 156-587 Exam With Confidence Using Practice Dumps

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.

To see the list of processes monitored by the WatchDog process (CPWD), you use thecpwd_admin listcommand.

Option A (cpstat fw -f watchdog): Shows firewall status and statistics for the "fw" context, not necessarily the list of monitored processes.

Option B (fw ctl get str watchdog): Not a valid parameter for retrieving the list of monitored processes; “fw ctl” deals with kernel parameters.

Option C (cpwd_admin list): Correct command that lists all processes monitored by CPWD, their status, and how many times they have been restarted.

Option D (ps -ef | grep watchd): This will list any running process that matches the string “watchd” but will not specifically detail which processes are being monitored by CPWD.

Therefore, the best answer iscpwd_admin list.
