Question 1 You are creating a report in Power BI Desktop. You load a data extract that includes a free text field named coll. You need to analyze the frequency distribution of the string lengths in col1. The solution must not affect the size of the model. What should you do?

• In the report, add a DAX calculated column that calculates the length of col1
• In the report, add a DAX function that calculates the average length of col1
• From Power Query Editor, add a column that calculates the length of col1
• From Power Query Editor, change the distribution for the Column profile to group by length for col1

Question 2 You have a collection of reports for the HR department of your company. The datasets use row-level security (RLS). The company has multiple sales regions. Each sales region has an HR manager. You need to ensure that the HR managers can interact with the data from their region only. The HR managers must be prevented from changing the layout of the reports. How should you provision access to the reports for the HR managers?

• Publish the reports in an app and grant the HR managers access permission.
• Create a new workspace, copy the datasets and reports, and add the HR managers as members of the workspace.
• Publish the reports to a different workspace other than the one hosting the datasets.
• Add the HR managers as members of the existing workspace that hosts the reports and the datasets.

Question 3 You need to provide a user with the ability to add members to a workspace. The solution must use the principle of least privilege. Which role should you assign to the user?

• Viewer
• Admin
• Contributor
• Member

Question 4 Users only use the date part of the Sales_Date field. Only rows with a Status of Finished are used in analysis. You need to reduce the load times of the query without affecting the analysis. Which two actions achieve this goal? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.

• Remove the rows in which Sales[Status] has a value of Canceled.
• Remove Sales[Sales_Date].
• Change the data type of Sale[Delivery_Time] to Integer.

Question 6 You have a custom connector that returns ID, From, To, Subject, Body, and Has Attachments for every email sent during the past year. More than 10 million records are returned.

The solution must minimize the model size. What should you do?

• From Model view, set the Subject and Body columns to Hidden.
• Remove the Subject and Body columns during the import.
• Implement row-level security (RLS) so that the report recipients can only see results based on the emails they sent
