A technician receives an automated notification indicating that a single hard drive in a server's RAID 5 array has failed, placing the storage volume into a degraded state. Which TWO of the following actions should the technician perform to restore full RAID redundancy without losing existing data?
- Replace the failed hard drive with a functional drive of equal or greater capacity.Cevap
- Initiate or confirm the array rebuild process to recalculate parity across the drives.Cevap
- CReformat all remaining operational drives in the array prior to inserting the replacement drive.
- DDelete the degraded volume configuration and reconfigure the operational drives into a RAID 0 array.
Cevap
To restore redundancy safely without data loss, the technician must replace the failed drive with one of equal or greater capacity and initiate or allow the array rebuild process to recalculate parity data onto the new disk.
A single failed drive in a RAID 5 configuration causes the array to run in a degraded state while retaining all data via distributed parity. Replacing the single broken disk with a drive of equal or larger size and initiating a rebuild recalculates lost parity data and restores fault tolerance without data loss.
