SK0-005 server-hardware-installation-management Practice Question
A server has been experiencing random crashes and generating memory-related errors in the system event log. The technician has already run memory diagnostics which show frequent errors on a single DIMM. The server has four DIMMs installed. Which of the following is the BEST next step?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Replace the failing DIMM with a known good, matching module
With diagnostics confirming errors on a specific DIMM, the best action is to replace that faulty module. Reseating may not fix a physical failure. Updating BIOS or replacing all DIMMs is unnecessary and could be wasteful.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Update the BIOS firmware
Why it's wrong here
A BIOS update might address some memory compatibility problems, but the errors are already isolated to a specific stick, indicating hardware failure.
- ✗
Replace all four DIMMs to prevent future issues
Why it's wrong here
Replacing all DIMMs is costly and not required if only one module is faulty; the other three may be healthy.
- ✓
Replace the failing DIMM with a known good, matching module
Why this is correct
Targeted replacement of the defective component is the most efficient and appropriate resolution after diagnostic confirmation.
- ✗
Reseat all DIMMs and re-run diagnostics
Why it's wrong here
Reseating may temporarily address a poor connection, but frequent errors even after reseating suggest permanent failure, making replacement the definitive fix.
