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.

Common mistakes.

B. Master controller is not a defined role in the SCSI protocol architecture; the correct protocol-defined roles are initiator and target only.
C. A NAS head unit is associated with file-level protocols such as NFS and SMB, not block-level SCSI storage.
E. 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.
