Which requirement differentiates dual-domain from dual-path SAS?

A.
Dual-domain requires dual-port drives.

B.
Dual-domain requires less hardware.

C.
Dual-path requires dual-port controllers.

D.
Dual-path requires active SAS cables.

Explanation:
Read Redundancy in enterprise storage networks using dual-domain SAS
configurations document. One of the key differences between dual-domain and dual-path
architectures is the use of SAS or SATA drives. Dual-port SAS drives can provide the advantages
of complete pathway redundancy in a dual-domain configuration. Customers seeking lower cost
solutions can employ single port SATA drives in a dual-path configuration.
