Explanation
Box 1: Infrastrucrue Svcs
Infrastrucrue Svcs is a Premium workspace.
If users have a free license and the workspace is stored in Premium (dedicated) capacity, they will be able to view and interact with the content in that workspace.
If users have a free license and the workspace is stored in shared capacity (not premium), they will not be able to see the content in shared workspace, only "My workspace".
If users have pro license, they will be able to view and interact with the content in that workspace.
Box 2: Admin
We need to activate the Orpaned workspace.
An orphaned workspace is one that does not have an admin assigned.
If you're a Service Admin, you can now view all of your organization's workspaces through the Admin Portal in the user interface.
Graphical user interface, table Description automatically generated with medium confidence
It's easy to Recover an orphan from this screen. Simply select the workspace and click Recover, then add yourself or another user as an admin.

質問 # 32
You plan to create a Power Bl report that will use an OData feed as the data source. You will retrieve all the entities from two different collections by using the same service root The OData feed is still in development. The location of the feed will change once development is complete.
The report will be published before the OData feed development is complete.
You need to minimize development effort to change the data source once the location changes.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
正解：
解説：
1 - Create a parameter that contains the service root URI.
2 - Get data from OData feed source and use the parameter to populate the first part of the URL.
3 - From Advanced Editor, duplicate the query and change the resource path in the URL.
質問 # 33
You have a Power Bl workspace that contains one dataset and four reports that connect to the dataset. The dataset uses Import storage mode and contains the following data sources:
* A CSV file in an Azure Storage account
* An Azure Database for PostgreSQL database
You plan to use deployment pipelines to promote the content from development to test to production. There will be different data source locations for each stage. What should you include in the deployment pipeline to ensure that the appropriate data source locations are used during each stage?
- A. data source rules
- B. auto-binding across pipelines
- C. selective deployment
- D. parameter rules
正解：D
解説：
Explanation
Note: Create deployment rules
When working in a deployment pipeline, different stages may have different configurations. For example, each stage can have different databases or different query parameters. The development stage might query sample data from the database, while the test and production stages query the entire database.
When you deploy content between pipeline stages, configuring deployment rules enables you to allow changes to content, while keeping some settings intact. For example, if you want a dataset in a production stage to point to a production database, you can define a rule for this. The rule is defined in the production stage, under the appropriate dataset. Once the rule is defined, content deployed from test to production, will inherit the value as defined in the deployment rule, and will always apply as long as the rule is unchanged and valid.

You have a Power Bl dataset that has the query dependencies 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.
正解：
解説：
Explanation
Box 1: 3
Power Query doesn't start at the first query and work down, it starts at the bottom (last) query and works backwards, so 3 tables from 1 will cause it to process that first source table 3 times.
Box 2: Using Table.Buffer in the Orders query
Table.Buffer buffers a table in memory, isolating it from external changes during evaluation. Buffering is shallow. It forces the evaluation of any scalar cell values, but leaves non-scalar values (records, lists, tables, and so on) as-is.
Note that using this function might or might not make your queries run faster. In some cases, it can make your queries run more slowly due to the added cost of reading all the data and storing it in memory, as well as the fact that buffering prevents downstream folding.
Example 1
Load all the rows of a SQL table into memory, so that any downstream operations will no longer be able to query the SQL server.
Usage
let
Source = Sql.Database("SomeSQLServer", "MyDb"),
MyTable = Source{[Item="MyTable"]}[Data],
BufferMyTable = Table.Buffer(dbo_MyTable)
in
BufferMyTable
Output
table

質問 # 37
You have a dataset that contains a table named UserPermissions. UserPermissions contains the following data.
You plan to create a security role named User Security for the dataset. You need to filter the dataset based on the current users. What should you include in the DAX expression?
- A. [User] = USEROBJECTID()
- B. [UserPermissions] - USERPRINCIPALNAME()
- C. [UserPermissions] - USERNAME()
- D. [User] = USERNAME()
- E. [User] = USERPRINCIPALNAME()

- F. Configure the data sources to use DirectQuery.
正解：E、F
解説：
Explanation
Automatic page refresh in Power BI enables your active report page to query for new data, at a predefined cadence, for DirectQuery sources.
Automatic page refresh is available for DirectQuery sources and some LiveConnect scenarios, so it will only be available when you are connected to a supported data source. This restriction applies to both automatic page refresh types.

Topic 2, Litware, Inc. Overview
Litware, Inc. is a retail company that sells outdoor recreational goods and accessories. The company sells goods both online and at its stores located in six countries.
Azure Resources
Litware has the following Azure resources:
* An Azure Synapse Analytics workspace named synapseworkspace1
* An Azure Data Lake Storage Gen2 account named datalake1 that is associated with synapseworkspace1
* A Synapse Analytics dedicated SQL pool named SQLDW
Dedicated SQL Pool
SQLDW contains a dimensional model that contains the following table.
SQLDW contains the following additional tables.
SQLDW contains a view named dbo.CustomerPurchases that creates a distinct list of values from dbo.Customer [customeriD], dbo.Customer
[CustomerEmail], dbo.ProductfProductID] and dbo.Product[ProductName].
The sales data in SQLDW is updated every 30 minutes. Records in dbo.SalesTransactions are updated in SQLDW up to three days after being created. The records do NOT change after three days.
Power BI
Litware has a new Power Bl tenant that contains an empty workspace named Sales Analytics.
All users have Power B1 Premium per user licenses.
IT data analysts are workspace administrators. The IT data analysts will create datasets and reports.
A single imported dataset will be created to support the company's sales analytics goals. The dataset will be refreshed every 30 minutes.
Analytics Goals
Litware identifies the following analytics goals:
* Provide historical reporting of sales by product and channel over time.
* Allow sales managers to perform ad hoc sales reporting with minimal effort.
* Perform market basket analysis to understand which products are commonly purchased in the same transaction.
* Identify which customers should receive promotional emails based on their likelihood of purchasing promoted products.
Litware plans to monitor the adoption of Power Bl reports over time. The company wants custom Power Bl usage reporting that includes the percent change of users that view reports in the Sales Analytics workspace each month.
Security Requirements
Litware identifies the following security requirements for the analytics environment:
* All the users in the sales department and the marketing department must be able to see Power B1 reports that contain market basket analysis and data about which customers are likely to purchase a product.
* Customer contact data in SQLDW and the Power B1 dataset must be labeled as Sensitive. Records must be kept of any users that use the sensitive data.
* Sales associates must be prevented from seeing the CustomerEmail column in Power B1 reports.
* Sales managers must be prevented from modifying reports created by other users.
Development Process Requirements
Litware identifies the following development process requirements:
* SQLDW and datalake1 will act as the development environment. Once feature development is complete, all entities in synapseworkspace1 will be promoted to a test workspace, and then to a production workspace.
* Power Bl content must be deployed to test and production by using deployment pipelines.
* All SQL scripts must be stored in Azure Repos.
The IT data analysts prefer to build Power Bl reports in Synapse Studio.

質問 # 47
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You are using an Azure Synapse Analytics serverless SQL pool to query a collection of Apache Parquet files by using automatic schema inference. The files contain more than 40 million rows of UTF-8-encoded business names, survey names, and participant counts. The database is configured to use the default collation.
The queries use open row set and infer the schema shown in the following table.
You need to recommend changes to the queries to reduce I/O reads and tempdb usage.
Solution: You recommend defining a data source and view for the Parquet files. You recommend updating the query to use the view.
Does this meet the goal?
- A. No
- B. Yes
正解：A
解説：
Explanation
Solution: You recommend using OPENROWSET WITH to explicitly specify the maximum length for businessName and surveyName.
The size of the varchar(8000) columns are too big. Better reduce their size.
A SELECT...FROM OPENROWSET(BULK...) statement queries the data in a file directly, without importing the data into a table. SELECT...FROM OPENROWSET(BULK...) statements can also list bulk-column aliases by using a format file to specify column names, and also data types.
