CompTIA Server+ SK0-005 Practice Question
A rack-mounted Linux application server has rebooted twice in the last hour. iDRAC hardware logs show that the CPU temperature exceeded the vendor's shutdown threshold immediately before each reboot. You have established a theory that an overworked CPU is triggering a thermal safety shutdown. According to the CompTIA troubleshooting methodology, what is the most appropriate next step to test this theory before making any configuration changes?
Update the server's BIOS and chipset firmware to the latest versions.
Reseat the CPU heat sink and apply new thermal paste to improve heat transfer.
Restore the server from the most recent bare-metal backup to rule out operating-system corruption.
Run a controlled CPU stress test while monitoring onboard temperature sensors to see whether the server shuts down again.
