What is an advantage of NAS compared to SAN?
The correct answer is B. It functions in an existing IP environment. Network Attached Storage (NAS) provides the advantage of integrating seamlessly into an existing IP-based network environment, unlike Storage Area Networks (SANs) which often require dedicated infrastructure.

Why each option
Network Attached Storage (NAS) provides the advantage of integrating seamlessly into an existing IP-based network environment, unlike Storage Area Networks (SANs) which often require dedicated infrastructure.
Lossless throughput is often a characteristic associated with Fibre Channel SANs due to their dedicated nature and error detection/correction mechanisms, not a primary distinct advantage of NAS over SAN.
NAS leverages standard Ethernet and TCP/IP protocols, allowing it to integrate seamlessly into an existing IP network without requiring specialized hardware or separate Fibre Channel networks like SANs. This simplifies deployment and management within a typical network infrastructure.
While NAS supports NFS, 'enhanced NFS features' is too vague and not a fundamental, overarching advantage of NAS compared to SAN's core architecture.
Both NAS and SAN can offer various security features, but enhanced security is not an inherent or exclusive advantage of NAS over SAN in a general architectural comparison.
