What are two use cases for creating hierarchies from the Data pane? Choose two.

1. A. To organize related fields together
2. B. To create faster-performing queries
3. C. To concatenate all fields into a single field
4. D. To add drilldown functionality for fields

Correct Answer: AD
Hierarchies in Tableau are used to define a drill-down path through your data. By creating a hierarchy, you can organize related fields together, which makes it easier to navigate complex data models. This also allows users to explore data at different levels of detail, from the highest level of the hierarchy to the most granular details, simply by clicking to expand and collapse levels of the hierarchy in the view.
