In a NetApp storage system, which of the following types of access is associated with LUNs in SAN configurations?

• A. Block access
• B. File access
• C. Application-level access
• D. User-level access

Answer: (A)

LUNs in SAN configurations provide block storage to hosts. A LUN is a logical block device that the host attaches and uses like a disk, which you can partition, format, and mount at the operating system level. This is the essence of block access, where the host works with raw storage blocks rather than files. File access refers to NAS-style access (sharing files and directories over protocols like NFS or SMB), which is not how LUNs are consumed. Application-level and user-level access aren’t standard ways storage is described for LUNs in SANs; they don’t capture how the host interacts with the storage as a block device.
