5 free sample questions from the Understanding Tableau Concepts domain, with answers and explanations. The full TDS-C01 bank has 51 questions across 4 domains. Questions are scenario-based and written from the official Tableau exam guide.
Which of these is the correct hierarchy of Tableau workbook structure, from smallest to largest container?
A worksheet is a single view; a dashboard combines multiple worksheets; a story sequences worksheets and/or dashboards into a narrative. The other orderings scramble this containment.
By default, where does Tableau place DIMENSIONS and MEASURES in the Data pane?
Tableau separates fields into dimensions (qualitative/categorical) and measures (quantitative, aggregatable), assigning them by data type on connection — though users can reclassify fields. Options A, B, and C misstate this behavior.
A date field is placed on Columns as a CONTINUOUS field. What does the view show?
A continuous date creates a continuous axis spanning the date range (ideal for trend lines). A discrete date (B) would create distinct headers/panes instead. Tableau doesn't auto-create a pie (C), and dates can absolutely be continuous (D).
What is a MARK in a Tableau view?
A mark is a single visual element (bar, point, line, etc.) corresponding to one combination of dimensions (the view's level of detail), styled via the Marks card. It's not a filter (B), a data source (C), or a dashboard (D).
A user changes a numeric field from a measure to a dimension. What is the likely effect?
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 (A), change it to a date (B), or publish (D).
