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
✓
Reseat all memory modules and ensure proper slot population.
Reseating memory and checking population order (Option C) are the first steps because improper seating or incorrect slot placement can cause the BIOS to not recognize all modules. Updating BIOS (Option A) might help if a compatibility issue exists, but physical inspection should come first. Replacing the motherboard (Option B) is too extreme. Running memtest86 (Option D) is useful but should follow physical checks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Replace the motherboard.
Why it's wrong here
Motherboard failure is unlikely; the issue is more likely related to the new RAM installation.
- ✗
Run memtest86 immediately.
Why it's wrong here
Memory testing is important, but physical checking should be done first to avoid unnecessary diagnostic time.
- ✓
Reseat all memory modules and ensure proper slot population.
Why this is correct
This addresses the most common cause of unrecognized memory: poor connections or incorrect order of slots.
- ✗
Update the server BIOS firmware.
Why it's wrong here
BIOS updates can resolve compatibility issues but should not be the first step before checking physical installation.
