A. To create detailed, printable reports using a visual drag-and-drop interface

B. To write complex DAX formulas for data modeling

C. To design dashboards with interactive visuals only

D. To manage data sources and refresh schedules

2. Which of the following is the correct way to add a chart in Power BI Report Builder?

easy

A. Write a DAX formula to generate the chart

B. Import a chart image from external software

C. Drag and drop the Chart item from the toolbox onto the report canvas

D. Use SQL queries to create the chart directly

1. Step 1: Identify how visuals are added in Report Builder

   Report Builder uses drag-and-drop from the toolbox to add items like charts.

2. Step 2: Evaluate each option

   Drag and drop the Chart item from the toolbox onto the report canvas correctly describes dragging the Chart item onto the canvas. Others involve coding or importing images, which are not standard methods.

3. Final Answer:

   Drag and drop the Chart item from the toolbox onto the report canvas -> Option C

4. Quick Check:

   Drag-and-drop charts = Drag and drop the Chart item from the toolbox onto the report canvas [OK]

Hint: Charts come from toolbox drag-and-drop, not code [OK]

• Importing images instead of using built-in chart tools

3. Given a report with a table and a chart added in Report Builder, what happens when you preview the report?

medium

A. The report displays a static preview with data rendered in the table and chart

B. The report shows a live interactive dashboard with slicers

C. The report opens the data source query editor

D. The report automatically publishes to Power BI Service

Solution

1. Step 1: Understand the preview function in Report Builder

2. Step 2: Compare options with preview behavior

   The report displays a static preview with data rendered in the table and chart correctly describes a static preview. Options B, C, and D describe other unrelated actions.

3. Final Answer:

   The report displays a static preview with data rendered in the table and chart -> Option A

4. Quick Check:

   Preview = Static report view [OK]

Hint: Preview shows static report, not interactive dashboard [OK]

Common Mistakes:

• Expecting interactive slicers in Report Builder preview
• Thinking preview edits data source queries
• Assuming preview publishes report automatically

4. You added a table to your report in Report Builder but it shows no data when previewed. What is the most likely cause?

medium

A. The table was added using drag-and-drop from the toolbox

B. The data source connection is not configured or is invalid

C. The report was saved before adding data

D. The preview mode only shows charts, not tables

Solution

1. Step 1: Identify why a table shows no data in preview

   If the data source connection is missing or invalid, the table cannot retrieve data to display.

2. Step 2: Evaluate other options

   The table was added using drag-and-drop from the toolbox is normal behavior, C does not affect data display, and D is false because preview shows all report items.

3. Final Answer:

   The data source connection is not configured or is invalid -> Option B

4. Quick Check:

   No data in table = Data source issue [OK]

Hint: Check data source connection first if no data appears [OK]

Common Mistakes:

• Assuming drag-and-drop causes no data
• Thinking saving report affects data display
• Believing preview excludes tables

5. You want to create a report in Report Builder that includes a table, a chart, and a text box with a title. Which steps should you follow to build and share this report?

hard

A. Use Power BI Service to build the report; download it as PDF; upload to Report Builder

B. Write SQL queries for each visual; export the report as Excel; email it manually

C. Create visuals in Power BI Desktop; import them into Report Builder; publish directly
