You have a Power BI report that imports a date table and a sales table from an Azure SQL database data source. The sales table has the following date foreign keys:
Due Date
Order Date
Delivery Date
You need to support the analysis of sales over time based on all the date foreign keys.
Solution: For each date foreign key, you add inactive relationships between the sales table and the date table.

- A. Yes
- B. No
Answer:
b
Instead: Solution: From the Fields pane, you rename the date table as Due Date. You use a DAX expression to create Order Date and Delivery Date as calculated tables.

Question 2
DRAG DROP You have a Microsoft Excel spreadsheet named Excel1 that contains survey results.
You have a Power BI dashboard named DashboardA that has Q&A enabled.
You need to ensure that users who can access DashboardA can ask questions based on the contents of Excel1 and pin visuals based on their queries to
DashboardA. The solution must minimize development time.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Question 6
You have a Microsoft Power BI report. The size of PBIX file is 550 MB. The report is accessed by using an App workspace in shared capacity of powerbi.com.
The report uses an imported dataset that contains one fact table. The fact table contains 12 million rows. The dataset is scheduled to refresh twice a day at 08:00 and 17:00.
The report is a single page that contains 15 AppSource visuals and 10 default visuals.
Users say that the report is slow to load the visuals when they access and interact with the report.
You need to recommend a solution to improve the performance of the report.
What should you recommend?
- A. Implement row-level security (RLS).
- B. Remove unused columns from tables in the data model.
- C. Replace the default visuals with AppSource visuals.
- D. Enable visual interactions.

- B. Add a data field to the Legend field well.
- C. Increase the Sensitivity setting.
- D. Add a data field to the Secondary values field well.
Answer:
a
Adding anomaly detection automatically enriches the chart with anomalies, and the expected range of values. When a value goes outside this expected boundary, it's marked as an anomaly.
