HPE0-J74 · Question #31
Which benefit does dual-domain offer over dual-path SAS?
The correct answer is D. Dual-domain SAS implementations make it possible to tolerate host bus adapter (HBA) failure. 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.
