Why each option

NAS typically offers a more cost-effective storage solution compared to SAN due to simpler infrastructure requirements.

AHigher data integrity

Data integrity is more dependent on the specific RAID configuration and data protection measures implemented on the storage device itself, rather than whether it's NAS or SAN.

BLower cost of implementationCorrect

NAS (Network-Attached Storage) is generally simpler to set up and manage, requiring less specialized hardware (like Fibre Channel HBAs or switches) and software, which directly translates to a lower overall cost of implementation compared to a SAN (Storage Area Network). SANs often involve complex infrastructure and higher-end equipment, increasing expenses.

CHigher redundancy

Redundancy is typically achieved through RAID configurations or clustering within the storage system, which can be implemented in both NAS and SAN environments.

DIncreased performance

SANs are generally known for providing higher performance due to their block-level access and dedicated high-speed networks, whereas NAS operates at the file level over general-purpose networks.
