Microsoft Power BI Data Analyst Sample Questions (Q355-Q360):

NEW QUESTION # 355
You have a large dataset that contains more than 1 million rows. The table has a datetime column named Date.
You need to reduce the size of the data model.
What should you do?

A. Trim the Date column.
B. Change the data type of the Date column to Text.
C. Split the Date column into two columns, one that contains only the time and another that contains only the date.
D. Round the hour of the Date column to startOfHour.

Answer: C

Explanation:
We have to separate date & time tables. Also, we don't need to put the time into the date table, because the time is repeated every day.
Split your DateTime column into a separate date & time columns in fact table, so that you can join the date to the date table & the time to the time table. The time need to be converted to the nearest round minute or second so that every time in your data corresponds to a row in your time table.

NEW QUESTION # 356
In Power BI Desktop, you are building a sales report that contains two tables. Both tables have row-level security (RLS) configured.
You need to create a relationship between the tables. The solution must ensure that bidirectional cross-filtering honors the RLS settings.
What should you do?

A. Create an active relationship between the tables and select Apply security filter in both directions.
B. Create an inactive relationship between the tables and select Assume referential integrity.
C. Create an active relationship between the tables and select Assume referential integrity.
D. Create an inactive relationship between the tables and select Apply security filter in both directions.

Answer: A

Explanation:
Explanation
By default, row-level security filtering uses single-directional filters, whether the relationships are set to single direction or bi-directional. You can manually enable bi-directional cross-filtering with row-level security by selecting the relationship and checking the Apply security filter in both directions checkbox. Select this option when you've also implemented dynamic row-level security at the server level, where row-level security is based on username or login ID.
