MS-900 Describe Microsoft 365 apps and services Practice Question
A user wants to create a custom dashboard that displays key performance indicators from multiple data sources, such as Excel files and SharePoint lists. Which Microsoft 365 app should the user use?
⚠ Common exam trap
Watch out — candidates often confuse Microsoft Lists or Excel as capable of creating dashboards because they can display data visually, but neither supports multi-source, interactive KPI dashboards with live data integration like Power BI does.

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
✓
Microsoft Power BI
Microsoft Power BI is the correct choice because it is a business analytics service designed to connect to multiple data sources—including Excel files and SharePoint lists—and create interactive, custom dashboards with key performance indicators (KPIs). Unlike the other options, Power BI provides built-in data modeling, visualization, and real-time refresh capabilities, making it the only app in this list that fulfills the requirement for a multi-source KPI dashboard.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Excel
Why it's wrong here
Excel can produce charts and pivot tables from imported data, but combining multiple live data sources into a single interactive dashboard requires manual setup and refresh; it lacks the governed, real-time sharing and natural-language querying of a dedicated BI platform. Thus it is not the optimal choice for a custom, key-metric dashboard.
- ✗
Microsoft Lists
Why it's wrong here
Microsoft Lists is a data-management app for creating structured lists (e.g., items, issues, contacts) with views and basic formatting, but it has no capability to blend data from multiple sources, calculate measures, or render dynamic visual KPIs. It is designed for tracking and organizing records, not for dashboard-style analytics or cross-source aggregation.
- ✓
Microsoft Power BI
Why this is correct
Power BI is Microsoft's dedicated business analytics service that connects to dozens of data sources, builds a semantic model with DAX measures, and publishes interactive, shareable dashboards in the Power BI service. Its features such as custom visuals, real-time refresh, and row-level security make it the appropriate tool for creating a custom dashboard that displays key metrics.
- ✗
Microsoft Forms
Why it's wrong here
Microsoft Forms is a tool for creating surveys, quizzes, and polls, collecting responses into a flat table with limited built-in summary charts. It cannot connect to external data sources, model relationships, or build interactive, multi-view dashboards, so it is unsuitable for displaying key performance indicators from various business systems.
