The correct answer is C. Fault tolerance.
Fault tolerance is a concept in business continuity that refers to the ability of a system or network to continue functioning even when one or more components fail. In this case, the use of RAID technology ensures that if one hard drive in the array fails, the data will still be accessible and not lost. This is achieved by storing redundant data across multiple drives in the array so that if one drive fails, the data can be rebuilt using the remaining drives.
File backup and data restoration, on the other hand, refer to the process of creating copies of data and restoring it in case of data loss. Restoring access refers to the process of regaining access to a system or network after a disruption.
It is important to note that while RAID technology provides some level of fault tolerance, it is not a substitute for a comprehensive disaster recovery plan. A disaster recovery plan should include backups, replication, and other measures to ensure that critical data and systems can be recovered in the event of a major disruption.
