Q1. You are a sales manager tracking the Profit Margin by Order Date on a Power BI dashboard. You want to be notified whenever the Profit Margin falls below 15%. What feature in Power BI allows you to configure such notifications?
Answer: D. Alerts
Data alerts in the Power BI service monitor dashboard tiles and trigger email notifications when metric thresholds are met. Subscriptions only send scheduled snapshots, while filters and bookmarks are interactive reporting tools that do not send alerts.
Q2. You need to load data from multiple Excel files stored in a SharePoint Online folder into a single table in Power BI. The files have identical structures. What is the most efficient method to achieve this?
Answer: C. Use the SharePoint Folder connector to combine the files into a single table
The SharePoint Folder connector accurately targets files stored in SharePoint Online and natively combines them into a single table. The standard Folder connector is practically identical for SharePoint, making option B an equally defensible choice.
Q3. You are developing a Power BI dashboard for a company that handles real-time financial transactions. The business requires up-to-the-minute data updates to monitor transactions as they occur. The dataset is very large, and data security is…
Answer: B. DirectQuery mode, because it supports real-time data updates directly from the source.
DirectQuery is correct because it queries the underlying source live, meeting the up-to-the-minute requirement without importing sensitive data into memory. For the exam, remember Import mode is faster but requires scheduled refreshes and stores data locally.
Q4. You are managing a Power BI workspace named SalesAnalysis and need to assign a role to a user that allows them to add and remove members from this workspace. The user should not be able to modify the workspace's content or settings. Which…
Answer: C. Member
The Member role is correct because it permits managing workspace membership without granting the broad administrative control or content publishing rights. Remember that Contributors can edit content but cannot manage members.
Q5. A Power BI Data Analyst is configuring Row-Level Security (RLS) for a sales dataset with three regions: North America, Europe, and Asia. Each regional sales team should only see their own region's data. The analyst needs to ensure users ar…
Answer: B. Assign users or security groups to the appropriate RLS roles in the dataset security settings
Assigning users to roles in the dataset security settings enforces row-level security dynamically based on the user viewing the report. Workspace roles are incorrect because they control environment access, not data filtering.
Q6. You are tasked with creating a Power BI report to detect potentially fraudulent transactions in your company's financial data. The data resides in an Azure SQL Database and includes transaction logs with columns Transaction ID, Customer ID…
Answer: C. Use the Azure SQL Database connector in DirectQuery mode, create measures for anomaly detection, and publish the report to the Power BI service.
Using DirectQuery with Azure SQL provides the real-time data access needed to monitor immediate transaction anomalies. Importing data or using scheduled refreshes is incorrect because the resulting latency prevents the required live detection.
Q7. You have a Power BI dataset that contains a table named Products. You want to make the Products table available as an organizational data type in Excel so that Excel users can easily access product information directly within their workshe…
Answer: C. Publish the dataset to Power BI Service, then certify the dataset and share it to Excel as an organizational data type.
Publishing and certifying the dataset promotes it as a trusted source, which can then be exposed as an organizational data type. Simply endorsing the dataset is incorrect because it misses the explicit step of sharing it to Excel.
Q8. A Power BI Data Analyst is tasked with enabling a department manager to create a dashboard using visuals from an existing Power BI report in a workspace. The manager should not be able to modify the underlying dataset or report but must ha…
Answer: B. Grant the manager Contributor role in the workspace and instruct them to create a dashboard using the report's visuals.
Granting the Contributor role lets the manager pin visuals to a new dashboard without altering the source dataset. Option E changes the user's workspace context unnecessarily, whereas Contributor natively supports creating personal dashboards directly from existing workspace reports.
Q9. The Sales Analytics Team at Company A has created a line chart in Power BI to track the Sum of Order Total over time. They've enabled specific analytics features to better understand data variability and reliability. In the Error Bars conf…
Answer: A. Only the lower Error Bar will be displayed, extending downward by 20%.
Setting the upper bound to 0% effectively hides the upper error bar, while the 20% lower bound draws it downward. This visually represents the potential variability below the data points. The configuration is perfectly valid in Power BI desktop.
Q10. You have a Power BI dataset in Import mode connected to an on-premises SQL Server database. You want to set up a refresh strategy that ensures the dataset is updated every day at midnight and at noon. Which of the following configurations…
Answer: A. Configure a data gateway and set up scheduled refresh twice a day
A scheduled refresh requires a data gateway to securely bridge on-premises SQL Server data into Power BI Service. Incremental refresh requires partitions rather than fixed schedules, and Power Automate is unnecessary overhead for standard scheduling.
Q11. At Company A, the Sales Team frequently accesses Power BI reports on their mobile devices to monitor key business metrics. In the mobile layout, there's a visual titled "Sales Trends 2022" displaying a KPI value of 6.67M, representing the…
Answer: D. A goal value and its percentage achievement
KPI visuals display an actual value alongside a target goal, showing how the metric tracks against expectations. Progress bars or pie charts are separate visual types, while trendlines are typically shown in line charts.
Q12. You are tasked with using DirectQuery in a Power BI dataflow to ensure the latest data is always available for a report. The data source is a SQL Server database. Which steps should you perform?
Answer: D. Create a dataflow in Power BI, Choose the DirectQuery mode for data connectivity, Use the Power Query editor to transform data as needed, Connect the dataflow to the Power BI dataset using DirectQuery.
Creating a dataflow, selecting DirectQuery, transforming the data, and linking it to the dataset provides live connectivity. Saving the dataflow alone is incorrect because you must connect it to the dataset to build reports.
Q13. You have a Power BI dataset that needs to connect to a PostgreSQL database hosted in a virtual network on Azure and ensure the dataset is updated daily. You need to configure the Power BI service for this connection and schedule a daily re…
Answer: C. II, III, IV, VIII
A virtual network gateway securely connects to the Azure PostgreSQL database without needing personal machines. Configuring scheduled refresh updates the data daily, while setting the owner as an admin ensures they have proper gateway management access.
Q14. You are developing a custom visual for Power BI to display sales data. You need to create this visual using TypeScript and integrate it into Power BI for use in reports. What are the steps to correctly create and deploy a custom visual for…
Answer: D. VI – I – III – V – VII – IV – II
The standard workflow requires creating the project, coding in TypeScript, packaging the file, and then testing it locally. Deployment to the Power BI service logically follows successful local validation, as deploying untested code disrupts end users.
