Which statement accurately describes the Single Initiator Single Target zone model?

In the SIST model, each zone is scoped to one initiator HBA card and one target disk controller, providing maximum isolation and dedicated access between a single host adapter device and a single storage controller. This device-level definition ensures that a disruption or misconfiguration affecting one HBA or controller does not impact other zones.

This choice incorrectly narrows the scope to an individual HBA port rather than the HBA card; the SIST model is defined at the device (card and controller) level, not at the per-port level.

This choice incorrectly identifies the target as a SAN fabric rather than a specific storage disk controller, fundamentally misrepresenting what the 'single target' in SIST refers to.

This choice incorrectly identifies the target as an entire SAN array, which encompasses multiple controllers, whereas SIST specifies a single disk controller as the target.
