A physical drive that is installed and remains in the storage pool as a reserve is called a:

• A. Backup Recovery Drive
• B. Ready Replacement Drive
• C. Hot Spare
• D. Mirror

Answer: (C)

Hot spare refers to a physical disk that is installed and kept in reserve inside the storage pool, ready to automatically take over if another disk fails. This setup allows the system to quickly rebuild data onto the spare, maintaining redundancy and availability without manual intervention. It’s different from a Mirror, which is about duplicating data across drives for redundancy rather than serving as a ready-to-use replacement. Backup Recovery Drive and Ready Replacement Drive aren’t the standard terms used for this purpose in typical storage configurations.
