CompTIA Server+ SK0-005 Practice Question
During an overnight health check you notice that a Windows Server 2019 virtualization host has logged dozens of WHEA-Logger Event ID 18 entries that report "Corrected ECC memory error" for Physical Memory Bank 1, DIMM B2. The iDRAC Lifecycle Log also lists more than 100 MEM0701 warnings (correctable error-rate exceeded) for the same module in the last 24 hours. You have a brief maintenance window this evening and must determine whether the DIMM itself or the motherboard slot is at fault before ordering parts. Which action should you take first to isolate the root cause while keeping downtime to a minimum?
Run chkdsk /f on the system volume to correct possible file-system corruption.
Replace the system board and all installed memory modules during the maintenance window.
Disable memory interleaving in the BIOS so the affected channel carries less traffic.
Move the indicated DIMM to an empty slot on the same memory channel, reboot, and monitor to see whether ECC errors follow the module.
