PL-300 Visualize and analyze the data Practice Question
You are a Power BI data analyst for a healthcare organization. You build a report page containing a card visual that displays total patient admissions, a slicer for hospital department, and a table visual listing patient details. A physician selects the 'Cardiology' department in the slicer. She then notices that the card visual updates to show only Cardiology admissions, but the table visual still shows all patients from every department. She wants both visuals to respond to the slicer. What should you do?
⚠ Common exam trap
The trap here is assuming that slicers always filter every visual on the page; in fact, visual interactions can be individually disabled, so the table may be intentionally or accidentally set to not respond.
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
✓
Edit the interactions for the slicer so that the table visual is filtered by the slicer.
Slicers filter other visuals by default, but individual interactions can be disabled. The table visual's interaction with the slicer was likely set to 'None', so it displays unfiltered data. Using 'Edit interactions' to set the table to be filtered resolves the issue and ensures consistent cross-filtering across the page.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add the Department column to the table visual's visual-level filters and set it to 'Cardiology'.
Why it's wrong here
Hard-coding a filter to 'Cardiology' would permanently restrict the table to that department, defeating the purpose of the slicer. The requirement is for the table to respond dynamically to whatever department the user selects, not to show a fixed department.
- ✗
Change the slicer's selection mode to 'Single select' and enable 'Show Select All'.
Why it's wrong here
Selection mode controls how many items a user can pick in the slicer; it does not change whether the slicer filters other visuals. Enabling 'Show Select All' adds a Select All option, but the table would still ignore the slicer if its interaction is set to None.
- ✗
Convert the table visual to a matrix and enable 'Stepped layout'.
Why it's wrong here
Changing the visual type to a matrix does not alter how slicers interact with it. The interaction setting remains the same regardless of whether it is a table or matrix. The issue is the interaction configuration, not the visual type.
- ✓
Edit the interactions for the slicer so that the table visual is filtered by the slicer.
Why this is correct
By default, slicers filter all other visuals on the page, but interactions can be modified. The table visual is likely set to 'None' for this slicer. Opening 'Edit interactions' and setting the table to be filtered will make it respond to the department selection, matching the card's behavior.
