Which technology uses parity/strip?

Deduplication
Compression
Erasure coding

The correct answer is: Erasure coding

Erasure coding is a data protection technology that utilizes parity to ensure data resilience and integrity across distributed storage systems. This technique breaks data into fragments, expands it with parity data, and distributes it across different storage nodes. The purpose of erasure coding is to provide fault tolerance and prevent data loss in case of hardware failures by allowing the original data to be reconstructed even if some fragments are lost. In contrast, deduplication focuses on eliminating redundant copies of data to save storage space, while compression reduces the size of data by eliminating redundancy within the dataset but does not involve data fragmentation or replication strategies associated with parity. Thus, erasure coding is distinctly characterized by its use of parity and striping to safeguard data across multiple locations, making it the correct choice in this context.
