Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Slicer
A slicer filters or highlights data based on selection, making it ideal for category selection. Bookmarks save a state, drillthrough navigates to another page, and tooltips show details on hover.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Slicer
Why this is correct
A slicer is an on-canvas visual control that displays a list of product categories and lets users click or multi-select values to instantly filter or highlight other visuals on the page. It remains visible as a persistent UI element, supports keyboard and assistive technologies, and allows ad hoc selection, making it the standard interactive tool for allowing users to highlight different product categories without pre-configuring every scenario.
- ✗
Tooltip
Why it's wrong here
Tooltips are hover-activated overlays that provide supplementary information about a specific data point, but they do not capture a user's click to change the active category or update the report's filter context. Hovering over a product category may reveal metrics or descriptions, yet it does not apply a highlight to that category across other visuals or alter the query. Tooltips are purely descriptive and fail to support user-driven selection or highlighting.
- ✗
Bookmarks
Why it's wrong here
Bookmarks capture a complete snapshot of the report page, including filter, slicer, and sort settings, and they can restore that exact view when clicked. To support category highlighting with bookmarks, a developer would need to pre-save a separate bookmark for every possible product category and then use a bookmark navigator to switch among those fixed states; this does not give users direct, free-form control to highlight any category on the fly. Bookmarks are therefore a way to save and recall views, not an organic selection mechanism.
- ✗
Drillthrough
Why it's wrong here
Drillthrough is a navigation mechanism that moves the user from a selected data point to a different report page filtered to that data point, typically for detailed analysis. It does not let users stay on the current page and switch category highlights; instead, it changes the page context and applies a fixed originating filter. Since the requirement is to highlight different product categories in place, drillthrough's page-changing behavior makes it inappropriate for this task.
