SK0-004 · Question #648
When a technician is given an iSCSI LUN, the server will be connected to which of the following? (Choose two.)
The correct answer is A. SAN D. NAS. iSCSI is an IP-based block storage protocol, and a server assigned an iSCSI LUN can be connected to either a SAN or a NAS device that hosts iSCSI targets.

Why each option
iSCSI is an IP-based block storage protocol, and a server assigned an iSCSI LUN can be connected to either a SAN or a NAS device that hosts iSCSI targets.
iSCSI is fundamentally a SAN protocol that encapsulates SCSI block-level commands over an IP network, making SAN the primary storage architecture used when a server is assigned an iSCSI LUN.
SATA is a physical drive interface used for local internal drive connections inside a server or enclosure, not a network storage protocol.
SAS is a physical serial attached SCSI bus interface for local drive connections, not a network-facing storage architecture associated with iSCSI.
Many NAS devices support iSCSI target functionality, allowing them to present block-level LUNs over IP in addition to file-level protocols like NFS or SMB, so a server with an iSCSI LUN may connect to a NAS as well.
SSD refers to a type of storage media based on flash memory, not a storage network protocol or architecture a server connects to.
