    e. Select Column profile.
  4. You have the following three versions of an Azure SQL database:
    You have a dataset that uses the development database as a data source.
    You need to configure the dataset so that you can easily change the data source between the development, test, and production database servers from
    Which should you do?
    a. Create a JSON file that contains the database server names. Import the JSON file to the dataset.
    b. Create a parameter and update the queries to use the parameter.
    c. Create a query for each database server and hide the development tables.

Check if your answers are correct or not here

1. c.
Explanation: The only way to visualize a streaming dataset is to add a tile and use the streaming dataset as a custom streaming data source.
2. d.
Explanation: In this section, we can easily see valid, Error and Empty percentage of data values associated with the Selected table.
3. d & e.
Explanation: Data Profiling, Quality & Distribution in Power BI / Power Query features
To enable these features, you need to go to the View tab à Data Preview Group Ã
4. d.
Explanation: With privacy level settings, you can specify an isolation level that defines the degree that one data source must be isolated from other data sources.
An Organizational data source limits the visibility of a data source to a trusted group of people. An Organizational data source is isolated from all Public data sources but is visible to other Organizational data sources.
5. c.
Explanation: With Power Query you can Split Date and Time into Separate Columns by using a transform
6. b.
Explanation: With Power BI Desktop, when you connect to your data source, it’s always possible to import a copy of the data into the Power BI Desktop. For some data sources, an alternative approach is available: connect directly to the data source using DirectQuery.
7. a.
Explanation: Combining data means connecting to two or more data sources, shaping them as needed, then consolidating them into a useful query.
When you have one or more columns that you would like to add to another query, you merge the queries.
8. b.
Explanation: You can add synonyms to tables and columns.
Note: This step applies specifically to Q&A (and not to Power BI reports in general). Users often have a variety of terms they use to refer to the same thing, such as total sales, net sales, total net sales. You can add these synonyms to tables and columns in the Power BI model.

9. c.
Explanation: Using AD Security Groups, you no longer need to maintain a long list of users.
All that you will need to do is to put in the AD Security group with the required permissions and Power BI will do the REST! This means a small and simple security file with the permissions and AD Security group.
10. c.
Explanation: A line chart or line graph displays the evolution of one or several numeric variables. Data points are connected by straight line segments. A line chart is often used to visualize a trend in data over intervals of time “” a time series “” thus the line is often drawn chronologically.
