CompTIA Server+ SK0-005 Practice Question

A CentOS Stream 9 virtualization host has begun rebooting unexpectedly during nightly backups. Each crash shows messages like:

[ 49783.441002] mce: [Hardware Error]: CPU 3: Machine Check: 0 Bank 8: b200000000070f0f
[ 49783.441002] mce: [Hardware Error]: TSC 0 ADDR ffffba020b400000 MISC 138a0003018
[ 49783.441003] mce: [Hardware Error]: MEMORY CONTROLLER RD_CHANNEL1_DIMM0: multi-bit ECC error
[ 49783.441004] Kernel panic - not syncing: Fatal Machine check

After the host restarts, no filesystem corruption is reported and disk SMART tests pass. Which action will BEST address the root cause and return the server to a stable state?

  • Update the RAID/HBA firmware and force a full array consistency check

  • Disable all CPU C-states and Intel SpeedStep (or AMD Cool'n'Quiet) in UEFI/BIOS

  • Rebuild the current kernel's initramfs image and regenerate GRUB entries

  • Replace the DIMM in Channel 1 Slot 0, then rerun memory diagnostics before returning the host to production
