Question 98

You are modeling data by using Microsoft Power BI. Part of the data model is a large Microsoft SQL Server table named Order that has more than 100 million records. During the development process, you need to import a sample of the data from the Order table. Solution: From Power Query Editor, you import the table and then add a filter step to the query. Does this meet the goal?

Answer 98

No This would load the entire table in the first step. Instead: You add a WHERE clause to the SQL statement.

Question 99

You are modeling data by using Microsoft Power BI. Part of the data model is a large Microsoft SQL Server table named Order that has more than 100 million records. During the development process, you need to import a sample of the data from the Order table. Solution: You write a DAX expression that uses the FILTER function. Does this meet the goal?

Answer 99

No Instead: You add a WHERE clause to the SQL statement. Note: DAX is not a language designed to fetch the data like SQL rather than used for data analysis purposes. It is always a better and recommended approach to transform the data as close to the data source itself. For example, your data source is a relational database; then, it's better to go with T-SQL. SQL is a structured query language, whereas DAX is a formula language used for data analysis purposes. When our data is stored in some structured database systems like SQL server management studio, MySQL, or others, we have to use SQL to fetch the stored data.

Question 103

You plan to create Power BI dataset to analyze attendance at a school. Data will come from two separate views named View1 and View2 in an Azure SQL database. The views can be related based on the Class ID column. Class ID is the unique identifier for the specified class, period, teacher, and school year. For example, the same class can be taught by the same teacher during two different periods, but the class will have a different class ID. You need to design a star schema data model by using the data in both views. The solution must facilitate the following analysis: ✑ The count of classes that occur by period ✑ The count of students in attendance by period by day ✑ The average number of students attending a class each month In which table should you include the Teacher First Name and Period Number fields? To answer, select the appropriate options in the answer area. Teacher first name: * attendance fact * class dimension * teacher dimension * teacher fact period number: * attendance fact * class dimension * teacher dimension * teacher fact

Question 104

There are four departments in the Departments table. You need to ensure that users can see the data of their respective department only. What should you do? A. Create a slicer that filters Departments based on DepartmentID. B. Create a row-level security (RLS) role for each department, and then define the membership of the role. C. Create a DepartmentID parameter to filter the Departments table. D. To the ConfidentialData table, add a calculated measure that uses the CURRENTGROUP DAX function.

Answer 104

B. Create a row-level security (RLS) role for each department, and then define the membership of the role. **Row-level security (RLS) with Power BI can be used to restrict data access for given users. Filters restrict data access at the row level, and you can define filters within roles.**

Question 105

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

Answer 105

B. Create an active relationship between the tables and select Apply security filter in both directions. **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.**

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: 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. Does this meet the goal? A. Yes B. No

Answer 114

A Here's a methodology to refactor a model from a single role-playing dimension-type table, to a design with one table per role. 1. Remove any inactive relationships. 2. Consider renaming the role-playing dimension-type table to better describe its role. In the example (not present here), the Airport table is related to the ArrivalAirport column of the Flight table, so it's renamed as Arrival Airport. 3. Create a copy of the role-playing table, providing it with a name that reflects its role. If it's an Import table, we recommend defining a calculated table. If it's a DirectQuery table, you can duplicate the Power Query query. In the example, the Departure Airport table was created by using the following calculated table definition. Departure Airport = 'Arrival Airport' Create an active relationship to relate the new table. 4. Consider renaming the columns in the tables so they accurately reflect their role. In the example, all columns are prefixed with the word Departure or Arrival. These names ensure report visuals, by default, will have self-describing and non-ambiguous labels. It also improves the Q&A experience, allowing users to easily write their questions. 5. Consider adding descriptions to role-playing tables. (In the Fields pane, a description appears in a tooltip when a report author hovers their cursor over the table.) This way, you can communicate any additional filter propagation details to your report authors.
