問題文

Two redundancy schemes protect the same twelve devices: one writes a second copy of every block and one computes extra pieces across the set. Which pair states what the mirrored scheme shortens and what the coded scheme raises?

選択肢

1. The specification for the two schemes weighs both costs, so the mirrored scheme shortens the whole recall and the coded scheme raises the extra compute in that comparison.
2. The specification for the two schemes weighs both costs, so the mirrored scheme shortens the whole recall and the coded scheme raises the extra conversion in that comparison.
3. The specification for the two schemes weighs both costs, so the mirrored scheme shortens the whole rebuild and the coded scheme raises the extra compute in that comparison.
