Which one is not a Layer in SCSI Model for distributed communication:
-
SCSI Application Layer
-
SCSI Transport Layer
-
Interconnect Layer
-
None of the Above
D
Correct answer
Explanation
The SCSI architectural model for distributed communication comprises exactly three layers: the SCSI Application Layer (client commands), SCSI Transport Layer (transport services), and Interconnect Layer (physical transport). Since all three options A, B, and C are valid layers in the standard SCSI model, the correct answer is 'None of the Above' - there is no fourth layer that would make any of these incorrect.
