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.
Correct Answer: A
Explanation/Reference:
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.
