Not sure about COUNT(DISTINCT %AccountOwnerId), could be overkill.

I disagree, COUNT(DISTINCT %AccountOwnerId) seems more accurate.

I’m a bit confused about the use of the percentage sign in the options. Does it mean anything specific for the COUNT function?

I feel like we practiced a similar question, and I think COUNT(TOTAL %AccountOwnerId) was mentioned as less efficient.

I remember we discussed how COUNT can be affected by null values, so I think option B might be the safest choice.

I’m not entirely sure, but I think COUNT(DISTINCT %AccountOwnerId) could be useful if there are duplicates.

This looks like a straightforward question about choosing a digital forensics service provider. I'm pretty confident I can identify the two key attributes they're looking for.
