CheckPoint Check Point Certified Troubleshooting Expert - R81.20 Sample Questions (Q55-Q60):
NEW QUESTION # 55
What is the best way to resolve an issue caused by a frozen process?
Answer: A
Explanation:
When a process is frozen (hung or unresponsive), the typical method to resolve it is to kill the process. On Check Point, you can use cpwd_admin kill -name <ProcessName> or a standard Linux kill -9 <PID> command if necessary. You then allow CPWD (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 typically must kill the 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."

NEW QUESTION # 56
Which of the following daemons is used for Threat Extraction?
Answer: B
NEW QUESTION # 57
You run a free-command on a gateway and notice that the Swap column is not zero Choose the best answer
Answer: D
Explanation:
When the free command on a Linux-based system (like a Check Point Gaia gateway) shows a non-zero value in the "Swap" column, it indicates that the system has utilized its swap space. Swap space is a portion of the hard disk designated to act as virtual RAM when the physical RAM is fully utilized.
The most direct and accurate explanation for swap usage is that the system's demand for Random Access Memory (RAM) exceeded the available physical RAM, forcing the operating system to move some less frequently used memory pages from RAM to the swap space on the disk. This frees up physical RAM for more active processes.
Let's analyze the options:
A . Utilization of ram is high and swap file had to be used: This is the correct and fundamental reason. Swap is used precisely because RAM utilization reached a point where the system needed more memory than was physically available.
B . Swap file is used regularly because RAM memory is reserved for management traffic: While Check Point gateways handle management traffic, operating systems do not typically use swap "regularly" due to a fixed reservation of RAM for such traffic in a way that would routinely force swapping under normal conditions. If management traffic is excessively high and consumes too much RAM, it would fall under the general case of high RAM utilization.
C . Swap memory is used for heavy connections when RAM memory is full: This describes a common cause for high RAM utilization on a firewall. Heavy connections can consume significant memory resources. When this consumption leads to RAM exhaustion, swap will indeed be used. However, option A is a more general and direct explanation of why swap is used, regardless of the specific cause of high RAM utilization. Option C is a specific scenario leading to the condition described in A.
D . Its ole Swap is used to increase performance: This statement is incorrect. Swapping to disk is significantly slower than accessing RAM. Therefore, swap usage generally indicates a performance bottleneck (or potential for one) rather than a performance enhancement. While virtual memory (which includes swap) allows a system to run more or larger applications than its physical RAM would normally allow, the act of swapping itself is detrimental to performance.
Conclusion: The best answer is A because it directly and accurately describes the immediate reason for swap usage: high RAM utilization necessitating the use of the swap file. Option C, while plausible as a cause of high RAM utilization, is a specific instance, whereas A is the overarching reason swap comes into play.
Reference (General Linux/System Administration Principles and supported by CCTE exam preparation materials): This understanding is based on fundamental principles of how operating systems manage memory and swap space. Check Point CCTE R81.20 exam preparation materials also affirm this understanding for similar questions. For instance, a question identical to this one appearing in CCTE exam preparation resources typically points to option A as the correct answer.
