Domain 1: Connect to and Transform Data
- Connect to files (Excel, CSV, JSON, PDF, spatial), databases, and published data sources from the Connect pane.
- Choose a live connection for up-to-date data or an extract (.hyper) for speed, portability, and offline use; extracts can be aggregated and filtered.
- Use the Data Interpreter to clean messy spreadsheets, and set data types and geographic roles on the Data Source page.
- Understand the Tableau data model: the logical layer uses relationships (flexible, context-aware) while the physical layer uses joins inside a logical table.
- Relationships differ from joins - they do not force a single join type and avoid the duplication or dropped rows that joins can cause - so prefer them unless you need a specific join.
- Joins (inner, left, right, full outer) combine columns and can change row counts; unions append rows from tables with the same structure.
- Data blending links separate data sources on a common field (primary and secondary) and is used when sources are at different levels of detail or already published.
- Reshape data with Pivot (columns to rows), Split and Custom Split, folders, hierarchies, groups, and bins.
- Tableau Prep Builder cleans and shapes data in a visual flow of Input, Clean, Pivot, Aggregate, Join, Union, and Output steps.
- Distinguish dimensions from measures and discrete (blue) from continuous (green) fields, because that choice drives the whole analysis.
Domain 2: Explore and Analyze Data
- Write calculated fields; a calculation is either row-level or aggregate, and you cannot mix an aggregate and a non-aggregate in one expression.
- Use aggregate functions (SUM, AVG, COUNT, COUNTD, MIN, MAX, MEDIAN, ATTR) and logical functions (IF/ELSEIF, CASE, IIF, ISNULL, IFNULL, ZN).
- Level of Detail expressions control the granularity of an aggregate: {FIXED} ignores the view's dimensions, {INCLUDE} adds a dimension, and {EXCLUDE} removes one.
- Remember the order of operations: a FIXED LOD is computed before dimension filters (so it ignores them) but after context filters (so it respects them).
- Table calculations compute on the query result in the view - Running Total, Percent of Total, Rank, Difference, Moving Average - and depend on the layout.
- Control a table calculation with Compute Using / partitioning and addressing (Table, Pane, Cell, or specific dimensions); functions include RUNNING_SUM, WINDOW_SUM, INDEX, RANK, LOOKUP, and TOTAL.
- Filters apply in a set order: extract, data source, context, dimension, FIXED LOD, measure, then table-calculation filters.
- A context filter creates a temporary subset, which is what makes a Top N filter or a FIXED LOD operate within that subset.
- Add analytics with the Analytics pane: reference lines and bands, trend lines, forecasting, clustering, and box plots.
- Use parameters (what-if inputs and measure/dimension swaps), sets (dynamic top-N or condition-based, IN/OUT, set actions), groups, and bins to slice and compare.
Domain 3: Create Content
- Match the chart to the question: bars for comparison, lines for trends over time, scatter for correlation, histograms for distribution, maps for geography, and dual-axis or combo charts to compare measures.
- Show Me suggests chart types and indicates the fields each one needs.
- The Marks card sets the mark type and the Color, Size, Label, Detail, Tooltip, Shape, and Angle properties; a field on Detail adds granularity without an axis.
- Discrete fields create headers and panes while continuous fields create axes, so placement on Rows and Columns changes the view.
- Build a dual-axis chart and use Synchronize Axis to align two measures on one pair of axes.
- Use Measure Names and Measure Values to show several measures in one view.
- Maps use geographic roles and latitude/longitude; choose filled (choropleth) maps for regions and symbol maps for points, and add map layers or custom territories.
- Assemble dashboards from sheets using tiled or floating objects and layout containers; add text, image, web page, navigation, and Show/Hide objects.
- Add interactivity with dashboard actions - Filter, Highlight, Go to URL, Go to Sheet, Parameter, and Set actions - triggered on hover, select, or menu.
- Format at the worksheet or workbook level, edit tooltips (including Viz in Tooltip), add annotations, and build Stories from sequential story points.
Domain 4: Publish and Manage Content on Tableau Server and Tableau Cloud
- Publish workbooks and data sources from Tableau Desktop into a project, choosing whether to embed external files and credentials.
- Publish a data source as a single source of truth so multiple workbooks reuse it; certify it so users see the certified badge.
- Schedule extract refreshes (full or incremental) on Tableau Cloud or Server, and use Tableau Bridge to refresh on-premises data for Tableau Cloud.
- Manage access with the permissions model: projects, groups, users, and permission rules whose capabilities (View, Filter, Download, Web Edit, Save) can be allowed or denied.
- Site roles (Creator, Explorer, Viewer) determine what a user can do, from full authoring down to viewing published content.
- Share views and workbooks, save custom views, and add favorites so people find content quickly.
- Set up subscriptions (emailed snapshots on a schedule) and data-driven alerts (triggered when a continuous measure crosses a threshold).
- Use web authoring and Explore in the browser to edit or build without Tableau Desktop, and download content where permitted.
- Revision history lets you restore a previous version, and Ask Data and Explain Data support self-service exploration.
- Tableau Public is a free platform for public sharing and is not a substitute for the governed Tableau Cloud or Server.
Tableau Certified Data Analyst exam tips
- Weight your prep toward Explore and Analyze Data (41%) and Create Content (26%) - together two-thirds of the exam. Be fluent with calculated fields, LOD expressions, table calculations, filters, parameters and sets, chart choices, the Marks card, and dashboards.
- Nail the three calculation types and when each changes: a FIXED LOD is independent of the view's dimensions, an aggregate follows the view, and a table calculation depends on the layout and Compute Using direction. Being able to predict which number changes when you add a dimension or re-sort is heavily tested.
- Memorize the filter order of operations (extract, data source, context, dimension, FIXED LOD, measure, table calc). It explains why a context filter is needed for a correct Top N and how FIXED interacts with filters.
- Know your combining options cold: relationships (flexible, context-aware, the default) vs joins (fixed type, can duplicate or drop rows) vs blends (different data sources on a linking field) vs unions (append rows). Pick the right one for the scenario.
- Practice in real Tableau as you study - the exam asks what a feature does and which approach fits a scenario, and those answers come fastest from having built them. Build dashboards with actions, dual-axis charts, LODs, table calculations and parameters, and rehearse publishing to Tableau Cloud with an extract refresh schedule.
Study guide FAQ
What is the format of the Tableau Certified Data Analyst exam?
Salesforce lists 60 scored multiple-choice and multiple-select questions plus five unscored questions, and a passing score of 65%. The time limit is 105 minutes. It is delivered at a test center or online.
Is there still a hands-on lab?
No. Salesforce's current description of the Salesforce Certified Tableau Data Analyst exam lists only multiple-choice and multiple-select questions; the earlier version of the exam included a performance-based lab. Hands-on practice in Tableau is still the best preparation, because many questions describe a task and ask which feature or calculation accomplishes it.
What happened to the Tableau Desktop Specialist?
Salesforce moved Tableau certifications into its own credential program and now offers role-based credentials. The Salesforce Certified Tableau Data Analyst is the analyst-level credential, covering analysis, dashboards, and publishing and managing content on Tableau Cloud and Tableau Server.
Do I need to know both Tableau Desktop and Tableau Cloud/Server?
Yes. Most of the exam is Tableau Desktop analysis and authoring, but the Publish and Manage Content domain (9%) covers publishing workbooks and data sources, permissions and site roles, extract refresh schedules, subscriptions, and alerts on Tableau Cloud and Tableau Server.
Is CertGrid's practice official Tableau material?
No. CertGrid is an independent practice platform and is not affiliated with or endorsed by Tableau or Salesforce. These questions are original and written to mirror the current exam guide's four domains so you can rehearse the objectives. Always confirm the current exam guide on the official Tableau certification page before your exam.

Four sections: "Connect to and Transform Data: 24%", "Explore and Analyze Data: 41%", "Create Content: 26%", "Publish and Manage Content on Tableau Server and Tableau Cloud: 9%" - the domain weights and names used by CertGrid practice exams. No hands-on lab is listed. The 105-minute limit is not on this page; it comes from prep sites that quote the Salesforce exam guide (help.salesforce.com article 005298984, which renders only in a browser). The older Tableau-hosted exam guide PDF (last revised 2022) described 120 minutes, 30 knowledge items plus a hands-on lab and a 750 scaled pass mark; that format is superseded.
