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.

Question

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

Options

  • ADual-path SAS implementations make it possible to tolerate host bus adapter (HIBA) failure.
  • BDual-domain SAS implementations provide some lower cost solutions that cover cable failure.
  • CDual-path SAS implementations provide full redundancy of a SAS solution.
  • DDual-domain SAS implementations make it possible to tolerate host bus adapter (HBA) failure.
