A technician is configuring a new server with four disks for the development team. The requirements are disk redundancy and maximum usable disk capacity. Which of the following RAID levels should be used for this server?
Correct Answer: C
RAID 5offers bothdisk redundancyandmaximum usable disk capacityby using block-level striping with parity. RAID 5 allows one drive to fail while still retaining data, and it uses only one disk's worth of space for parity, maximizing the usable capacity.
* RAID 5 (Answer C):Provides redundancy with only one disk's space used for parity, maximizing storage.
* RAID 0 (Option A):Provides no redundancy; if one drive fails, all data is lost.
* RAID 1 (Option B):Mirrors data, so redundancy is provided, but only half the capacity is usable.
* RAID 10 (Option D):Combines RAID 1 and 0 for high performance and redundancy but requires half the disk space for mirroring.
