A. B. C. D.D.
RAID 5 is a type of RAID (Redundant Array of Independent Disks) configuration that provides both fault tolerance and failure recovery.
In a RAID 5 configuration, data is distributed across multiple disks, with parity information being stored on each disk. This allows the system to continue operating even if one disk fails, as the data on the failed disk can be reconstructed from the remaining disks using the parity information.
RAID 5 provides a balance between performance, cost, and data protection. It offers better performance than RAID 1 (mirroring) and RAID 3/4 (dedicated parity), while still providing redundancy in case of a disk failure. However, it is not as fault-tolerant as RAID 6, which uses two sets of parity information for added protection against data loss.
In summary, the BEST description of RAID 5 is that it provides fault tolerance and failure recovery.
