Question 56

You are using DAX Studio to query an XMLA endpoint.
You need to identify the duplicate values in a column named Email in a table named Subscription.
How should you complete the DAX expression? To answer, drag the appropriate values to the targets. Each
value may be used once, more than once. may need to drag the split bar between panes or scroll to view
content.
NOTE: Each correct selection is worth one point.

Question 57

You are using DAX Studio to analyze a slow-running report query. You need to identify inefficient join operations in the query. What should you review?

A.the query statistics
B.the query plan
C.the query history
D.the server timings

Correct Answer: B

Open DAX Studio.
Paste the query there, enable Query Plan display and Server Timings, run your query (with clear cache), and then study the query plan for large row counts. Once the culprit is identified you can decide how to rewrite your DAX to make that part faster.

Topic 1, Contoso, Ltd
Data Infrastructure
Contoso has a 50-TB data warehouse that uses an instance of SQL Server on Azure Virtual Machines.
The data warehouse populates an Azure Synapse Analytics workspace that is accessed by the external customers. Currently, the customers can access alt the data.
Contoso has one Power Bl workspace named FinData that contains a single dataset. The dataset contains financial data from around the world. The workspace is used by 10 internal users and one external customer. The dataset has the following two data sources: the data warehouse and the Synapse Analytics serverless SQL pool.
Users frequently query the Synapse Analytics workspace by using Transact-SQL.
User Problems
Contoso identifies the following user issues:
* Some users indicate that the visuals in Power Bl reports are slow to render when making filter selections.
* Users indicate that queries against the serverless SQL pool fail occasionally because the size of tempdb has been exceeded.
* Users indicate that the data in Power Bl reports is stale. You discover that the refresh process of the Power Bl model occasionally times out Planned Changes Contoso plans to implement the following changes:
* Into the existing Power Bl dataset, integrate an external data source that is accessible by using the REST API.
* Build a new dataset in the FinData workspace by using data from the Synapse Analytics dedicated SQL pool.
* Provide all the customers with their own Power Bl workspace to create their own reports. Each workspace will use the new dataset in the FinData workspace.
* Implement subscription levels for the customers. Each subscription level will provide access to specific rows of financial data.
* Deploy prebuilt datasets to Power Bl to simplify the query experience of the customers.
* Provide internal users with the ability to incorporate machine learning models loaded to the dedicated SQL pool.

Question 58

You use Advanced Editor in Power Query Editor to edit a query that references two tables named Sales and
Commission. A sample of the data in the Sales table is shown in the following table.
