SG0-001 · Question #257
Which set of SCSI components are required to support SCSI command tag queuing?
The correct answer is A. adapter, adapter driver, device, device driver. SCSI command tag queuing requires end-to-end support from the host's hardware and software components to the storage device's hardware and software components.

Why each option
SCSI command tag queuing requires end-to-end support from the host's hardware and software components to the storage device's hardware and software components.
Command tag queuing is a feature that allows a SCSI target to process multiple commands concurrently, and its successful operation relies on end-to-end support, meaning the host-side components (adapter, adapter driver) must initiate and manage tagged commands, and the device-side components (device, device driver) must be capable of receiving and processing them. All these components must be present and capable of supporting this feature for it to function correctly.
This option omits the adapter driver, which is crucial for the operating system to interact with the HBA and implement command tag queuing.
