Question 1 of 30

An analyst is building a dashboard in Tableau that combines data from two distinct sources: one detailing customer support ticket volumes by region and another containing monthly marketing campaign spend per region. A direct join between these sources reveals a significant and unexpected increase in the total number of rows processed, impacting dashboard load times. Upon review, it\'s discovered that a many-to-many relationship exists between the regional identifiers in both datasets, without any specific aggregation or filtering applied at the join level. What is the most likely underlying technical reason for this performance issue and inflated row count?

The creation of a Cartesian product due to an unmanaged many-to-many join between the two data sources.
Tableau's automatic data type coercion leading to incompatible fields for joining.
The use of an inappropriate join type, such as a full outer join, when an inner join was intended.
An issue with the Tableau extract refresh process causing duplicate data entries.
