Test your basic knowledge of Power BI with these beginner-friendly interview questions. This quiz covers essential concepts, versions, components, and comparison points for Power BI, suitable for freshers or anyone preparing for Power BI interviews.
What is the primary purpose of Power BI in a business setting?
Explanation: Power BI is designed mainly to convert raw data from various sources into meaningful, interactive insights for informed decision making. Creating animations or managing payroll is not within its function. While Power BI has a mobile app, its main function is not to design mobile applications.
Why is Power BI considered beneficial for non-technical users?
Explanation: Power BI is user-friendly, allowing users without coding skills to create interactive dashboards and visualize data easily. Advanced programming languages are not required for basic use, and it's not limited to IT professionals. It does not handle legal contracts.
Which of the following data sources can Power BI connect to?
Explanation: Power BI can connect to digital data sources, such as Excel spreadsheets, cloud data, and other electronic formats. Handwritten notes, paper files, and physical calculators are not compatible data sources for Power BI.
Which component of Power BI is mainly used to extract, transform, and load data from various sources?
Explanation: Power Query is responsible for data extraction, transformation, and loading in Power BI. Power View focuses on data visualization, Power Map handles geographic data, and Power Chart is not a recognized Power BI component.
If you want to create relationships between tables and use DAX for calculations, which Power BI component should you use?
Explanation: Power Pivot is used for data modeling, establishing table relationships, and utilizing DAX formulas. Power Qu0026A is for interactive question answering, while Power Template and Power Layout are not Power BI components.
Which Power BI feature allows you to visualize geographic data in 3D based on location fields like city or state?
Explanation: Power Map is the feature that visualizes geo-spatial data in 3D. Power Query is for data preparation; Power Grid and Power Link are not parts of Power BI.
How can users access interactive Power BI dashboards on their smartphones?
Explanation: The Power BI Mobile Application allows users to access and interact with dashboards on mobile devices. Emailing files or using desktop apps doesn't provide interactive mobile access, and exporting to video removes interactivity.
What is the main function of Power Qu0026A in Power BI?
Explanation: Power Qu0026A lets users interact with data and ask questions in plain language for instant answers. The other options are unrelated to data querying or Power BI features.
Which Power BI component combines the functionality of Power View, Power Query, and Power Pivot?
Explanation: Power BI Desktop unifies data modeling, transformation, and visualization features in one place. Power BI Lite, Power Form, and Power Table are not official Power BI components.
Which advantage does Self-service BI offer over Managed Enterprise BI?
Explanation: Self-service BI allows easy, intuitive dashboard creation without coding, even for non-technical users. Unlike managed BI, it doesn’t require third-party vendors, isn’t limited by fixed data flows, and isn’t constrained by strict timelines.
Which of these is NOT an official version of Power BI?
Explanation: Power BI Ultra is not a real version; the main versions are Free/Desktop, Pro, and Premium. Only these last three represent official Power BI offerings.
What is the main purpose of Power View in Power BI?
Explanation: Power View is primarily for making interactive reports and visual displays such as charts. It does not transform data (that’s Power Query), and it doesn’t handle security or calendar tasks.
Which feature of Power BI lets you build custom calculations using DAX formulas?
Explanation: DAX formulas for custom calculations are used in Power Pivot. Other named options do not exist or do not work with DAX calculations in Power BI.
What feature in Power BI allows users to securely share reports and dashboards with stakeholders for real-time analysis?
Explanation: Power BI enables secure, real-time sharing via its cloud service. Offline printing and flash drives do not allow real-time updates, and texting summaries lacks the visual interactivity of a dashboard.
Which feature allows Power BI users to slice and dice data dynamically within reports?
Explanation: Slicers and filters are tools in Power BI that let users view different data subsets interactively. The other terms are either made-up or unrelated to data filtering.
How does Power Qu0026A enhance the user experience for data analysis in Power BI?
Explanation: Power Qu0026A converts user questions in natural language into analytics and visualizations on the spot. Printer formatting, simulating mouse clicks, or running antivirus are unrelated to Power Qu0026A’s purpose in Power BI.
