SG0-001 · Question #100
Which of the following technologies enables storage blocks to be reused following data deletion?
The correct answer is B. Thin reclamation. Thin reclamation is a storage feature that enables storage blocks to be efficiently reused after data deletion by identifying and returning previously allocated but unused capacity to a shared pool.

Why each option
Thin reclamation is a storage feature that enables storage blocks to be efficiently reused after data deletion by identifying and returning previously allocated but unused capacity to a shared pool.
Redundant fabrics provide high availability and fault tolerance for storage networks, but they do not enable the reuse of storage blocks following data deletion.
Thin reclamation, typically employed with thin-provisioned storage, allows the storage array to detect when blocks within a volume are no longer holding data and then deallocate those physical blocks, making them available for other volumes or applications.
Parity protection is a data protection mechanism used in RAID configurations to ensure data integrity and availability, not to reclaim and reuse deleted blocks.
Storage virtualization abstracts physical storage resources for flexible management, but the specific function of reusing blocks after deletion is performed by thin reclamation features.
