A drive for a RAID 1 array fails. Users are concerned that information could be lost. Which of the following is the best way to manage the situation?
The correct answer is C. Replacing the defective disk and syncing the new one so that all files are retained. In RAID 1 (mirroring), data is duplicated across two drives. If one drive fails, the array continues to function using the remaining drive. Replacing the failed disk and rebuilding (resyncing) the array restores full redundancy without data loss.
