A technician runs on a dual-core server and notes the following conditions: top top -- 14:32:27, 364 days, 14 users load average 60.5 12.4 13.6 Which of the following actions should the administrator take?

Options

ASchedule a mandatory reboot of the server
BWait for the load average to come back down on its own

Explanation

The top output shows a 1-minute load average of 60.5 on a dual-core server. Load average represents the number of processes waiting for CPU time; on a 2-core system, a load of 2.0 is 100% utilization. A load of 60.5 means roughly 30x the CPU capacity is being demanded, indicating at least one runaway process consuming excessive resources. The administrator should immediately identify and kill the runaway process(es) using tools like top, htop, or ps aux. Rebooting (A) is disruptive and doesn't address the root cause. Waiting (B) is inappropriate given the severity. Asking users to log off (D) is unlikely to resolve a runaway process.
