ProLiant Gen9 servers include these advanced memory protection features:
…
Dynamic fail-over to a spare DIMM rank or spare rank pair behind the same memory
controller. No OS involvement. You cannot enable this feature concurrently with memory mirroring. HP offers the rank sparing rather than DIMM sparing as rank sparing uses less spare memory resulting in less overhead.

B,C are for Smartarray controller. A -> is not for save cost. So I think D is correct.

Dear friend! I have passed my HP0-S42 exam few days ago, scored 92%! (The passing score of the HP0-S42 exam now is 67%)
I had 60 questions, including matching questions, single response questions, multiple responses and drag-and-drop questions. Functions, features, and benefits of HPE server products and solutions & Plan and design HPE server solutions are the hottest parts of the HP0-S42 exam, a lot of questions on them!
