Start Demonstrate the capabilities of Power BI PracticeA sales manager wants to create a dashboard that shows sales by region and product category. The data is stored in an Excel file that is updated weekly. What is the most efficient way to ensure the dashboard reflects the latest data?
Explanation: Option A is correct because it separates the report creation (in Power BI Desktop) from the data refresh schedule (in the Power BI service). By publishing the report once and configuring a daily scheduled refresh, the dashboard automatically reflects the latest data from the Excel file without manual intervention, which is the most efficient approach for weekly updates.
A company uses Power BI to monitor manufacturing efficiency. The dataset includes a column 'RunTime' (in minutes) and 'DownTime' (in minutes). A user wants to calculate 'Availability' as (RunTime / (RunTime + DownTime)) * 100. Which DAX measure should be used?
Explanation: Option A is correct because it uses the DIVIDE function to safely handle division by zero, and multiplies by 100 to express the result as a percentage. The formula sums RunTime and DownTime across all rows, then computes Availability = (Total RunTime / (Total RunTime + Total DownTime)) * 100, which matches the user's requirement exactly.
A financial analyst creates a Power BI report to compare quarterly revenue across years. The data has a 'Date' column and a 'Revenue' column. The analyst wants to display year-over-year growth for each quarter. Which visual and configuration would best achieve this?
Explanation: Option B is correct because a Matrix visual allows you to place years as columns and quarters as rows, then define a DAX measure for year-over-year (YoY) growth (e.g., (Current Year Revenue - Previous Year Revenue) / Previous Year Revenue). This directly compares each quarter’s revenue across years in a structured, tabular format, which is the most effective way to display YoY growth for each quarter.
A marketing team wants to share a Power BI dashboard with external stakeholders who do not have Power BI licenses. Which sharing method should the team use?
Explanation: Option C is correct because 'Publish to web' generates an embed code that creates a publicly accessible link to the Power BI dashboard, which can be viewed by anyone without requiring a Power BI license or authentication. This is the only method listed that allows external stakeholders without licenses to access the dashboard directly in a browser.
A data analyst notices that a Power BI report takes a long time to load when filtering by a specific date range. The data source is a SQL Server view that contains millions of rows. What is the most effective way to improve performance?
Explanation: Option B is correct because the performance bottleneck is at the data source level—millions of rows in a SQL Server view. Using DirectQuery with optimized indexes and filters pushes query execution back to SQL Server, allowing it to leverage database-level performance features like index seeks and query plan caching. This reduces the amount of data transferred and processed in Power BI, directly addressing the root cause of slow filtering.
