Which of the following techniques for ensuring cloud datacenter storage resiliency uses parity bits and disk striping?

The technique that employs parity bits and disk striping to enhance storage resiliency in cloud datacenters is RAID (Redundant Array of Independent Disks). RAID configurations achieve redundancy and increased performance by distributing data across multiple physical drives.

In specific RAID levels, such as RAID 5, data is striped across the disks in addition to storing parity information. Parity bits allow the system to reconstruct lost data from a failed drive, thereby providing fault tolerance. This method enhances both data redundancy and read/write speeds, making it a fundamental approach for ensuring that data in cloud storage remains resilient and accessible even in the event of hardware failures.

Other techniques listed in the question do not involve this combination of data distribution and error correction that RAID uses. Cloud-bursting is a hybrid cloud deployment technique used primarily for elastic scaling of resources, data dispersion refers to spreading data across various locations for performance or regulatory reasons, and SAN (Storage Area Network) is a specialized network providing access to consolidated block-level storage, which does not specifically utilize parity bits or striping as part of its architecture.
