Why each option

To guarantee that replicated offsite backup data cannot be changed, the company should implement WORM (Write Once, Read Many) technology.

ASAN

A SAN (Storage Area Network) is a network architecture for storage that provides block-level access, but it does not inherently guarantee data immutability without additional WORM-like features or specific configurations.

BWORMCorrect

WORM (Write Once, Read Many) is a data storage technology that explicitly prevents data from being modified or erased once it has been written, ensuring data immutability. This directly addresses the requirement to guarantee that replicated data cannot be changed after its initial writing, which is crucial for compliance and data integrity.
