Visual Recipes Test
For the Visual Recipe Test, one of the questions is as follows:
Which of the following must be defined when creating a Pivot recipe? (Select two.)
Let's say that you want to find distinct values of two columns in a dataset. If using the Distinct recipe without computing counts of deduplicated rows, how many columns will be in the output dataset?

Hi @PhilipBF
, I can suggest trying to run Pivot recipes without each of the possible answers and see which are absolutely required and which are (most often present but) not actually required. -

Hi @SeanA
, I tried that, but it seems like there's no answer. I didn't fill in anything for any of them. For the row identifier, Data Iku says Nothing selected, output will be a single row. Does that mean a row identifier isn't required because it will be selected anyway? -

Hi @PhilipBF
, thank you for your feedback. I think the question is trying to draw your attention to how the row identifier works. It can be helpful to have a mental model of how the output will be impacted having 0, 1, or even multiple row identifiers.
