You have a report page that shows sales by region. You want users to be able to select a region and see the corresponding sales details on the same page without navigating away. Which feature should you use?

Correct answer & explanation
✓
Slicer
A slicer is correct because it lets users interactively filter the report page by selecting a region, and the sales details visuals on that same page update in place without any navigation. This matches the requirement of staying on the same page while changing the displayed data. Drillthrough would not fit because it navigates users to a separate drillthrough page filtered to the selected item. A matrix with expand/collapse changes the level of detail within a single visual rather than filtering the whole page by region selection. A card visual only displays a single aggregated value and provides no selection mechanism.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Slicer
Why this is correct
The slicer is a dedicated on-page filter control that lets users choose region values; it directly cross-filters all other visuals on the report page, updating the sales numbers in real time based on the selection. Unlike drillthrough, it does not navigate away, and unlike a matrix's expansion, it actively filters the entire page's visuals. It is the correct answer because it provides interactive, immediate page-level filtering without altering the report layout.
- ✗
Drillthrough
Why it's wrong here
Drillthrough is a navigation feature that works by sending the user to a separate, pre-configured detail page whose visuals are filtered by the data point clicked (for example, a specific region). It does not filter the current report page; instead, it replaces the view entirely, so the original sales-by-region page is left behind. This makes it unsuitable for simply showing region-filtered sales on the same page; it is a drill-down to a different context, not a page-level cross-filter.
- ✗
Matrix with expand/collapse
Why it's wrong here
A matrix visual allows expand/collapse to drill down within its own hierarchy (e.g., country to state to city), but this action only changes the level of detail shown inside that matrix; it does not apply a filter to any other visual on the page. The matrix's expand/collapse is an intra-visual navigation mechanism, not an interactive cross-filter. Therefore, while it can reveal different sales breakdowns, it cannot filter the rest of the page's visuals by a region selection.
- ✗
Card visual
Why it's wrong here
A card visual is a static display of a single aggregated value (such as total sales), and it only reflects the current filter context of the page; it has no interactive capability to set or change those filters. Clicking or selecting a card does not cross-filter other visuals, and a card cannot act as a region selector. Thus, a card would show whatever sales figure results from the existing filters, but it cannot itself show sales by region interactively.
