A cloud administrator is configuring block-level storage. The storage must be configured to be resistant from faults. Given this scenario, which of the following would aid in establishing fault tolera

NAS provides file-level storage, not block-level, making it unsuitable for the requirement.

DAS with mirroring typically provides local fault tolerance and usually implies synchronous mirroring, not asynchronous redundancy for broader disaster recovery scenarios.

JBOD offers no inherent redundancy; implementing mirroring on JBOD provides local RAID-level fault tolerance, similar to DAS, and typically synchronous within a single system.

A SAN provides block-level storage, and replication is a common mechanism to create redundant copies of data across different locations. Asynchronous replication specifically writes data to the primary location first, then replicates it to the secondary without waiting for the secondary write, thereby establishing fault tolerance with asynchronous redundancy.
