Question 76 of 144
SK0-005 server-hardware-installation-management Practice Question
A technician is replacing a failed hard drive in a hot-swap RAID 5 array. After inserting the new drive, the RAID controller does not automatically rebuild. What should the technician do first?
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
✓
Manually initiate a rebuild from the RAID controller utility
Many RAID controllers require manual initiation of the rebuild process. Rebooting may not trigger it. Replacing with a different model is unnecessary. Checking cabling is less likely since the drive is detected. The technician should use the controller utility to start the rebuild.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Check the SAS cable connection
Why it's wrong here
Incorrect. Since the drive is inserted in a hot-swap bay, cabling is internal and unlikely to be loose.
- ✗
Reboot the server
Why it's wrong here
Incorrect. Rebooting may not force a rebuild; the controller typically waits for a manual command.
- ✗
Replace the drive with a different model
Why it's wrong here
Incorrect. Using a different model could cause compatibility issues; the rebuild should work with the same model.
- ✓
Manually initiate a rebuild from the RAID controller utility
Why this is correct
Correct. Most controllers require the administrator to manually start the rebuild after replacing a failed drive.
Quick reference
RAID Level Comparison
| RAID Level | Min Disks | Fault Tolerance | Read | Write | Usable Capacity |
|---|---|---|---|---|---|
| RAID 0 | 2 | None | Excellent | Excellent | 100% |
| RAID 1 | 2 | 1 disk | Good | Moderate | 50% |
| RAID 5 | 3 | 1 disk | Good | Moderate | 67–94% |
| RAID 6 | 4 | 2 disks | Good | Lower | 50–88% |
| RAID 10 | 4 | 1 disk per mirror | Excellent | Good | 50% |
RAID is not a backup strategy — it protects against disk failure but not against accidental deletion, ransomware, or site-level events.
