Changed Analytics-DA-201 Exam Questions

To combine two sets, they must have at least one dimension in common. In this case, Customers of 2020 and Top N Customers both have Customer Name as a dimension, so they can be combined using set operations such as union, intersection, or difference. Sellers of 2020 and Top N Products have different dimensions (Seller Name and Product Name), so they cannot be combined. References:

In Tableau, sets can be combined if they are created from the same dimension. From the options provided, " Customers of 2020 " and " Top N Customers " are likely created from the same dimension (Customers). Therefore, these two sets can be combined to create a new set that includes or excludes members based on the combined criteria. Combining sets like " Top N Products " with " Customers of 2020 " would not be feasible unless they are from the same dimension, which is typically not the case.

A Top N filter is applied to categorical members, so the field being filtered should be a discrete dimension. When a discrete dimension is placed on the Filters shelf in Tableau Desktop, the Filter dialog provides General, Wildcard, Condition, and Top tabs. The Top tab can then retain the top or bottom N members based on an aggregate measure, such as the top 10 customers by SUM(Sales). A continuous measure uses quantitative range filtering rather than the dimension-member Top interface. A table calculation is evaluated later in Tableau’s order of operations and is not the field type used to configure a standard Top N dimension filter. A set can itself be defined using a Top rule, but it is a separate object rather than the required field type for this filter. Therefore, C is correct.
