Understanding Tableau Concepts: free practice questions

5 sample questions from our 10-question bank for this domain — answers and explanations included. These are the same scenario-based style as the real Tableau exam.

1. A user changes a numeric field from a measure to a dimension. What is the likely effect?

  • A. Its values are treated as discrete categories to slice by, rather than being aggregated✓ Correct
  • B. The data source is deleted
  • C. It becomes a date field
  • D. The workbook is published
Explanation

Converting a measure to a dimension makes Tableau treat its distinct values as categories to segment the view, instead of aggregating them. It doesn't delete the source (B), change it to a date (C), or publish (D).

2. Which statement about discrete vs continuous fields is TRUE?

  • A. Discrete and continuous is a separate property from dimension vs measure — for example, a date dimension can be used as either discrete or continuous✓ Correct
  • B. Only measures can be continuous and only dimensions can be discrete, always
  • C. Discrete and continuous mean the same as dimension and measure
  • D. Continuous fields cannot appear on a view
Explanation

Discrete (blue) vs continuous (green) is independent of dimension vs measure; a date dimension, for instance, can be placed as discrete (headers) or continuous (axis). Option B is false (dimensions can be continuous and vice versa), C conflates the concepts, and D is false.

3. How do Tableau Desktop, Tableau Server/Cloud, and Tableau Public differ at a high level?

  • A. Desktop authors workbooks; Server/Cloud host and share them securely within an organization; Public is a free hosting platform where content is publicly visible✓ Correct
  • B. They are all the same product
  • C. Desktop is only for viewing published dashboards
  • D. Tableau Public keeps all content private
Explanation

Tableau Desktop is the authoring tool; Tableau Server (self-hosted) and Tableau Cloud (SaaS) host and share content with governance; Tableau Public is a free platform where published content is publicly accessible. Options B, C, and D misstate the products.

4. What does AGGREGATION mean in Tableau?

  • A. Rolling up measure values to the view's level of detail using a function like SUM, AVG, MIN, MAX, or COUNT✓ Correct
  • B. Deleting rows from the data source
  • C. Changing a field's data type
  • D. Publishing a workbook
Explanation

Aggregation combines measure values up to the granularity of the view using functions like SUM or AVG (Tableau aggregates measures by default). It's not deleting rows (B), changing data types (C), or publishing (D).

5. What determines the GRANULARITY (level of detail) of a Tableau view?

  • A. The combination of dimensions in the view — each unique combination is one mark✓ Correct
  • B. The number of measures only
  • C. The workbook file size
  • D. The color palette
Explanation

The dimensions on the view define its granularity: each distinct combination of dimension values forms one mark, and measures are aggregated to that level. Measures alone (B), file size (C), and color (D) don't set granularity.
