In block-level storage, SCSI commands eare transmitted between witch to devices? (Choose two)
The correct answer is D. initiator. In block-level storage, SCSI commands flow between an initiator (host HBA) and a target (storage device); both A and D are the correct answers for this choose-two question.

Why each option
In block-level storage, SCSI commands flow between an initiator (host HBA) and a target (storage device); both A and D are the correct answers for this choose-two question.
Master controller is not a defined role in the SCSI protocol architecture; the correct protocol-defined roles are initiator and target only.
A NAS head unit is associated with file-level protocols such as NFS and SMB, not block-level SCSI storage.
The initiator is the host-side entity, typically an HBA or iSCSI software adapter, that generates SCSI commands and sends I/O requests to storage. Paired with the target (choice A), these two roles define the complete SCSI communication model used in Fibre Channel, iSCSI, and FCoE block-level storage protocols.
A spine switch is a network infrastructure component in leaf-spine fabric topologies and does not participate as a SCSI endpoint in block-level storage transactions.
