You have a Power BI model that contains two tables named Sales and Date. Sales contains four columns named TotalCost, DueDate, ShipDate, and OrderDate. Date contains one column named Date.
The tables have the following relationships:
Sales[DueDate] and Date[Date]
Sales[ShipDate] and Date[Date]
Sales[OrderDate] and Date[Date]
The active relationship is on Sales[DueDate].
You need to create measures to count the number of orders by [ShipDate] and the orders by [OrderDate]. You must meet the goal without duplicating data or loading additional data.
Solution: You create measures that use the CALCULATE, COUNT, and USERELATIONSHIP DAX functions.
Does this meet the goal?
Yes
No

scatter chart
The Answer Is:
CYou 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

Create a theme as a PBIVlZ file and import the theme into Power Bl Desktop. You have a Power BI imported dataset that contains the data model shown in the following exhibit. Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic. NOTE: Each correct selection is worth one point. - cross filter direction - star schema You have a Power Bl semantic model that contains the following tables. You need to define a relationship from FactSales to DimProduct. The solution must ensure the fastest DAX query performance. Which cardinality should you use? one-to-one many-to-many many-to-one one-to-many You have a Microsoft Excel file in a Microsoft OneDrive folder. The file must be imported to a Power Bi dataset You need to ensure that the dataset can be refreshed in powefbi.com. Which two connectors can you use to connect to the file? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point. Text/CSV Folder Excel Workbook SharePoint folder Web - Copy and edit Path of the Excel file then use "Web" Connector: Option E - Copy and edit Path of the OneDrive folder then use "Sharepoint Folder" connector: Option D Source: https://www.youtube.com/watch?v=GGHbbg6yi-A You have a Power Bl report. You have the following tables. You have the following DAX measure. Vou have a Microsoft Power Bl Desktop report named Report! that uses an Azure SQL database as a data source. A user named User1 plans to create a report by using the same data source as Report1. You need to simplify the connection to the data source for User1. Which type of file should you create? PBIDS PBIT XLSX PBIX You have the Power Bl model shown in the following exhibit. 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? Create a row-level security (RLS) role for each department, and then define the membership of the role. Create a DepartmentID parameter to filter the Departments table. To the ConfidentialData table, add a calculated measure that uses the currentgroup DAX function. Create a slicer that filters Departments based on DepartmentID. You are creating a quick measure as shown in the following exhibit. You need to create a monthly rolling average measure for Sales over time-How should you configure the quick measure calculation? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point. Box 1: Total Sales We select the field Total Sales Box 2: Date Select a date field. Box 3: Month Monthly periods. You have two Power Bl reports named ReportA and ReportB that each uses a distinct color palette. You are creating a Power Bl dashboard that will include two visuals from each report You need to use a consistent dark theme for the dashboard. The solution must preserve the original colors of the reports. Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point. Upload a snapshot. Select the dark dashboard theme. Turn on tile flow. When pinning visuals to the dashboard, select Use destination theme. For the browser, set the color preference to dark mode. Adding an index key and normalizing casing in the data source would help resolve issues with undefined values and errors in a case-sensitive column. The index key can provide a unique identifier, and normalizing casing ensures consistency in the data, which would likely prevent the errors you encountered in the Power BI semantic model. You have a Power BI data model 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 three dates at the same time. Solution: For each date foreign key, you add inactive relationships between the sales table and the date table. Does this meet the goal? Yes No Simply adding inactive relationships between the sales table and the date table for each date foreign key does not fully meet the goal. While inactive relationships allow for flexibility, they alone do not enable analysis over time based on all three dates simultaneously. To achieve this, you would need to use DAX functions like USERELATIONSHIP to activate the appropriate relationship in your measures. Without this, the inactive relationships won’t be utilized in your calculations, meaning that analysis based on those dates won't work as intended. You publish a semantic model to the Power Bl service. The semantic model contains a connection to an on-premises Microsoft SQL Server database. You attempt to configure a scheduled refresh but cannot select the appropriate on-premises data gateway. You confirm the following with the administrator of the gateway: • You have the appropriate permissions to use the gateway. • The data source was created on the gateway. • The gateway has a status of Running. What is the most likely reason the gateway is unavailable? The server name in the PBIX file does not match the data source name in the gateway. The type of data source is not supported by the on-premises data gateway. The data source is configured to use single sign-on (SSO). The credentials for the data source are invalid. You have a semantic model named Model1. You have a Power BI report named RPT1 that is connected to Model1. RPT1 contains a table visual named Table1 that shows the results of multiple measures. You discover that the DAX query for Table1 runs slowly. You need to identify which measure is slowing query performance. What should you use? DAX query view Power Query Editor Model view Performance analyzer You have a Q&A visual that displays information from a table named Carriers as shown in the following exhibit. You need to ensure that users can ask questions by using the term airline or carrier. The solution must minimize changes to the data model. What should you do? Add a duplicate query named Airline. Add airline as a synonym of carrier. Rename the carrier column as airline in the Carriers query. Rename the query from Carriers to airlines. Add synonyms to tables and columns: 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. This step can be important. Even with straightforward table and column names, users of Q&A ask questions using the vocabulary that first comes to them. They're not choosing from a predefined list of columns. The more sensible synonyms you add, the better your users' experience is with your report.,
