Practice

1. What is the main difference between a dashboard and a report in Power BI?

easy

A. Dashboards show key info on one page; reports have multiple pages with details.

B. Dashboards have multiple pages; reports show info on one page only.

C. Dashboards are only for printing; reports are interactive.

D. Dashboards contain raw data; reports contain only charts.

Solution

1. Step 1: Understand dashboard purpose

   Dashboards provide a quick view of key information on a single page for fast understanding.

2. Step 2: Understand report purpose

   Reports contain multiple pages with detailed data and filters for deeper exploration.

3. Final Answer:

   Dashboards show key info on one page; reports have multiple pages with details. -> Option A

4. Quick Check:

   Dashboard = summary, Report = detailed [OK]

Hint: Dashboards = one page summary, reports = detailed multi-page [OK]

Common Mistakes:

• Confusing dashboards as multi-page
• Thinking reports are only for printing
• Believing dashboards contain raw data

2. Which of the following is the correct way to create a dashboard in Power BI?

easy

A. Write DAX formulas to build a dashboard page.

B. Create a dashboard first, then add reports inside it.

C. Create a report and pin visuals to a dashboard.

D. Use Power Query to design the dashboard layout.

Solution

1. Step 1: Understand dashboard creation process

   Dashboards are created by pinning visuals from reports to a single page.

2. Step 2: Eliminate incorrect options

   Dashboards are not created first, nor built with DAX or Power Query layouts.

3. Final Answer:

   Create a report and pin visuals to a dashboard. -> Option C

4. Quick Check:

   Pin visuals from reports = dashboard creation [OK]

Hint: Pin report visuals to dashboard to create it [OK]

   Filters on report pages do not carry over to dashboard visuals; dashboard visuals are snapshots.

3. Final Answer:

   Only the 3 pinned visuals on one page without filters. -> Option A

4. Quick Check:

   Dashboard = pinned visuals only [OK]

Hint: Dashboard shows only pinned visuals, no full pages [OK]

   If report data changed externally, you must refresh queries in Power BI Desktop before republishing to update the service dataset.

3. Final Answer:

   You forgot to refresh the Power BI Desktop file. -> Option B

4. Quick Check:

   Refresh Desktop queries + republish [OK]

Hint: Refresh Power BI Desktop file and republish after data changes [OK]
