Which access does an iSCSI or FC SAN provide to LUNs?

• A. block
• B. file
• C. VIIP
• D. VLD

Answer: (A)

Block storage is what iSCSI and FC SAN provide to LUNs. A LUN is a logical block device exported by the storage system, and when a host connects over iSCSI or FC it sees that LUN as a disk. The host then partitions and formats it with a file system (or uses it as raw blocks for databases), meaning access is at the block level rather than at the file level. File access, by contrast, would use NAS protocols like NFS or SMB to expose files and directories, not raw disks. So the best description is block access.
