XK0-005 Question #755: Real Exam Question with Answer & Explanation

Question

A systems administrator is receiving complaints about slow performance and system crashes. The administrator suspects memory and CPU issues. Which of the following is the first action the administrator should take to troubleshoot and resolve these issues?

Options

• ARun resource monitoring tools like top or htop to view the current CPU and memory use.
• BLook through the system logs and error messages to find any faults involving the CPU and
• CRemove and replace the CPU and memory components to address hardware issues.
• DReboot the server to clear any CPU and memory congestion.

Explanation

{"question_number": 10, "correct_answer": "A", "explanation": "Running resource monitoring tools like top or htop is the correct first action because troubleshooting should begin with observation - gathering real-time data on which processes are consuming CPU and memory, and how severe the current load is. This immediately reveals whether the problem is a runaway process, memory exhaustion, or something else, and guides all further steps. Reviewing logs (B) is valuable but is a secondary step after confirming the current state. Replacing hardware (C) is drastic and premature without any diagnostic evidence of a hardware failure. Rebooting (D) clears symptoms temporarily but provides no diagnostic information and risks data loss on a crashing system.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
