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?
Microsoft Excel
Why wrong: Can display data but not a dashboard with multiple sources easily.
Microsoft Lists
Why wrong: List management.
Microsoft Power BI
Business analytics service for interactive dashboards.
Microsoft Forms
Why wrong: Survey tool.
Answer choices
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
The trap here is that 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.
Detailed technical explanation
Power BI uses the Power Query engine (M language) to connect and transform data from hundreds of sources, including Excel files via the Excel connector and SharePoint lists via the SharePoint Online List connector. It supports DAX (Data Analysis Expressions) for creating calculated KPIs and measures, and its dashboard tiles can be pinned from multiple reports, enabling a consolidated view that refreshes on a schedule (e.g., via the Power BI service gateway). In a real-world scenario, a sales manager could combine an Excel sales forecast with a SharePoint list of customer interactions to build a real-time KPI dashboard without writing code.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
