Storage Redundancy — CompTIA A+ Core 1 (220-1101) Practice Questions
Storage redundancy means maintaining more than one copy of data so that a drive failure does not result in data loss. RAID 1 (mirroring) and RAID 5 (parity) are the primary hardware-level redundancy methods covered on the 220-1101 exam. Technicians must understand that redundancy is not a substitute for backups, since RAID protects against drive failure but not against accidental deletion, ransomware, or site-level disasters.
