The correct answer is B. SAN (Storage Area Network).
Storage network technologies refer to the various methods used to store data on networked devices. These devices can be located either on-premises or off-premises, and can include network-attached storage (NAS), storage area networks (SAN), fiber channel over Ethernet (FCoE), iSCSI, and FTP.
NAS (Network Attached Storage) is a type of file-level storage that provides shared storage to multiple devices on a network. It uses a protocol such as NFS or SMB to share files over the network. However, NAS does not inherently leverage block-level storage.
SAN (Storage Area Network), on the other hand, is a type of block-level storage that provides access to raw storage devices (such as disks or tapes) through a dedicated network. SAN uses a protocol such as Fibre Channel or iSCSI to provide block-level access to storage devices. SAN is a highly scalable, high-performance solution that is commonly used in enterprise environments.
FCoE (Fibre Channel over Ethernet) is a protocol that allows Fibre Channel traffic to be transported over Ethernet networks. FCoE allows organizations to leverage their existing Ethernet infrastructure while still providing the performance and reliability of Fibre Channel.
iSCSI (Internet Small Computer System Interface) is a protocol that provides block-level access to storage devices over a TCP/IP network. iSCSI is a cost-effective solution that is commonly used in small and medium-sized businesses.
FTP (File Transfer Protocol) is a protocol used for transferring files over a network. FTP does not provide block-level storage.
In conclusion, the storage network technology that inherently leverages block-level storage is SAN (Storage Area Network).
