The question says 'not usually used to improve ... performance'. Is this a typo?

I would have put the right answer of 'summary tables' on the side of 'usually used'.

Hi Ed,
the word "not" was meant to be there.
3 of the answers are usually used to improve DW performance (summary tables, partitioning and index), whilst 1 is not (backup).
Kind regards,
Vincent

I feel the question could have been worded better. Specifically, I am referring to this sentence:
Which one of the following things that is not usually used to improve data warehouse query performance?


That sentence sounds like it's asking: Which one of the following would help query performance but is not usually used?
However, that is not what the question is really asking.

I think removal of the word 'that' in the quoted QotD sentence above would help improve readability.
