Tableau-Desktop-Found Exploring and Analyzing Data Practice Question
You are analyzing sales data and need to identify the top 10 products by profit. You have dragged 'Product Name' to the Rows shelf and 'Profit' to the Columns shelf. What is the most efficient way to isolate only the top 10 performers?
⚠ Common exam trap
Many test-takers manually hide headers in the view or sort and filter using quick filters, missing that a native Top N filter operates efficiently at the data source level.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Drag Product Name to the Filters shelf, select the Top tab, and define a limit by field.
Using a Top N filter allows Tableau to perform the calculation at the data source level before rendering the visualization. This is more performant than using a manual hide or a set, as it dynamically adjusts if the underlying data changes. Mastering this technique is essential for creating clean, focused dashboards that guide stakeholders directly to the most critical business metrics without overwhelming them with unnecessary, low-value data points.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Drag Product Name to the Filters shelf, select the Top tab, and define a limit by field.
Why this is correct
The Top tab in the Filter dialog box automatically handles sorting and limiting the data set. By selecting the 'By field' option and choosing Profit with the 'Top' parameter, Tableau generates the necessary ranking logic. This is the standard, most reliable method for creating persistent, top-performing product lists.
- ✗
Sort the visualization in descending order and manually hide all rows after the tenth item.
Why it's wrong here
Manual hiding is a static operation that does not update when the data refreshes. If the underlying data changes, the list will no longer show the true top 10 products. This approach is prone to user error and lacks the dynamic nature required for robust, professional Tableau dashboard reporting.
- ✗
Create a calculated field using the RANK function and filter for values less than or equal to 10.
Why it's wrong here
While RANK can achieve this result, it requires the calculation to be computed across the table, which can be affected by the visualization's layout. Using a filter on the dimension itself is cleaner and avoids potential complications with compute-using settings that often confuse developers during complex report builds.
- ✗
Apply a wildcard filter to the Product Name dimension to include only the top 10 records.
Why it's wrong here
Wildcard filters are designed for string pattern matching, such as searching for product names containing specific text. They lack the mathematical logic required to evaluate quantitative measures like Profit. Attempting to use a wildcard filter for numerical ranking will result in an error or unexpected, incorrect query results.
