Question#4

You have a Microsoft Power BI data model that contains three tables named Orders, Date, and City.
There is a one-to-many relationship between Date and Orders and between City and Orders.
The model contains two row-level security (RLS) roles named Role1 and Role2. Role1 contains the following filter.
City[State Province] = "Kentucky"
Role2 contains the following filter.
Date[Calendar Year] = 2020
If a user is a member of both Role1 and Role2, what data will they see in a report that uses the model?

A. The user will see data for which the State Province value is Kentucky and the Calendar Year is 2020.

B. The user will see data for which the State Province value is Kentucky or the Calendar Year is 2020.

C. The user will see only data for which the State Province value is Kentucky.

D. The user will receive an error and will not be able to see the data in the report.

Question#5

HOTSPOT
You have two Azure SQL databases that contain the same tables and columns.
For each database, you create a query that retrieves data from a table named Customers.
You need to combine the Customer tables into a single table. The solution must minimize the size of the data model and support scheduled refresh in powerbi.com.
What should you do? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Explanation:
Box 1: Append Queries as New.
There are two primary ways of combining queries: merging and appending.
When you have one or more columns that you’d like to add to another query, you merge the queries.
When you have additional rows of data that you’d like to add to an existing query, you append the query.
Box 2: Disable loading the query to the data model
For every query that loads into model memory will be consumed. and Memory is our asset in the Model, less memory consumption leads to better performance in most of the cases. The best approach is to disable loading.
