CompTIA Server+ SK0-005 Practice Question

A 2U virtualization host suddenly shuts itself off after running CPU-intensive workloads for about ten minutes. When power is restored, the server's management controller shows entries similar to the following:

15:42:07  CPU1_Temp 100 °C - critical threshold exceeded
15:42:08  System action: Thermal trip - power shutdown

The ambient rack temperature is a steady 22 °C, firmware is current, and no OS errors are logged. Which hardware issue is the MOST likely root cause of these unexpected shutdowns?

  • The processor's cooling fan has stopped working, severely reducing airflow through the heatsink

  • The motherboard's CMOS battery is nearing end-of-life and no longer holds BIOS settings

  • A DIMM is intermittently throwing correctable ECC errors under heavy memory load

  • The RAID controller's cache battery is degraded, forcing the array into write-through mode
