Which benefit does dual-domain offer over dual-path SAS?

Which benefit does dual-domain offer over dual-path SAS?

A.
Dual-path SAS implementations make it possible to tolerate host bus adapter (HBA) failure.

B.
Dual-domain SAS implementations provide some lower cost solutions that cover cable failure.

C.
Dual-path SAS implementations provide full redundancy of a SAS solution.

D.
Dual-domain SAS implementations make it possible to tolerate host bus adapter (HBA) failure.

Explanation:
Dual-domain SAS implementations make it possible to tolerate host bus adapter (HBA) failure, external cable
failure, expander failure, failure in a spanned disk (JBOD) environment, and failure in Redundant Array of
Independent Disks (RAID) environments.
