QUESTION 6:

HOTSPOT

You have two Azure Storage accounts named Storage1 and Storage2. Each account holds one container and has the hierarchical namespace enabled. The system has files that contain data stored in the Apache Parquet format.

You need to copy folders and files from Storage1 to Storage2 by using a Data Factory copy activity. The solution must meet the following requirements:

Hot Area:

Correct Answer:

Box 1: Parquet
For Parquet datasets, the type property of the copy activity source must be set to ParquetSource.

Box 2: PreserveHierarchy
PreserveHierarchy (default): Preserves the file hierarchy in the target folder. The relative path of the source file to the source folder is identical to the relative path of the target file to the target folder.

Incorrect Answers:
FlattenHierarchy: All files from the source folder are in the first level of the target folder. The target files have autogenerated names.

MergeFiles: Merges all files from the source folder into one file. If the file name is specified, the merged file name is the specified name. Otherwise, it\’s an autogenerated file name.

QUESTION 10:

DRAG DROP

You have an Azure Stream Analytics job that is a Stream Analytics project solution in Microsoft Visual Studio. The job accepts data generated by IoT devices in JSON format.

You need to modify the job to accept data generated by the IoT devices in the Protobuf format.

Which three actions should you perform from Visual Studio in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Select and Place:

Correct Answer:

Step 1: Add an Azure Stream Analytics Custom Deserializer Project (.NET) project to the solution. Create a custom deserializer

1. Open Visual Studio and select File > New > Project. Search for Stream Analytics and select Azure Stream Analytics Custom Deserializer Project (.NET). Give the project a name, like Protobuf Deserializer.

2. In Solution Explorer, right-click your Protobuf Deserializer project and select Manage NuGet Packages from the menu. Then install Microsoft.Azure.StreamAnalytics and Google.Protobuf NuGet packages.

3. Add the MessageBodyProto class and the MessageBodyDeserializer class to your project.

4. Build the Protobuf Deserializer project.

Step 2: Add .NET deserializer code for Protobuf to the custom deserializer project Azure Stream Analytics has built-in support for three data formats: JSON, CSV, and Avro. With custom .NET deserializers, you can read data from other formats such as Protocol Buffer, Bond and other user defined formats for both cloud and edge jobs.

Step 3: Add an Azure Stream Analytics Application project to the solution Add an Azure Stream Analytics project In Solution Explorer, right-click the Protobuf Deserializer solution and select Add > New Project.

Under Azure Stream
Analytics > Stream Analytics, choose Azure Stream Analytics Application. Name it ProtobufCloudDeserializer and select OK.

Right-click References under the ProtobufCloudDeserializer Azure Stream Analytics project. Under Projects, add Protobuf Deserializer. It should be automatically populated for you.

Q1:BYou can identify anomalies by routing data via IoT Hub to a built-in ML model in Azure Stream Analytics.
Q2:BTo run a T-SQL query over a set of files within a folder or set of folders while treating them as a single entity or rowset, provide a path to a folder or a pattern (using wildcards) over a set of files or folders.
Q3:IMAGE
Q4:DFExecute (X) permission is required to traverse the child items of a folder. There are two kinds of access control lists (ACLs), Access ACLs and Default ACLs. Access ACLs: These control access to an object. Files and folders both have Access ACLs.

Default ACLs: A “template” of ACLs associated with a folder that determines the Access ACLs for any child items that are created under that folder. Files do not have Default ACLs.
Q5:AFrom Microsoft SQL Server Management Studio, set an email mask on the Email column. This is because “This feature cannot be set using the portal for Azure Synapse (use PowerShell or REST API) or SQL Managed Instance.”

So use Create table statement with Masking e.g. CREATE TABLE Membership (MemberID int IDENTITY PRIMARY KEY, FirstName varchar(100) MASKED WITH (FUNCTION = \’partial(1,”XXXXXXX”,0)\’) NULL, . . upvoted 24 times [email protected]
Q6:IMAGE
Q7:CYou can use Databricks Pools to Speed up your Data Pipelines and Scale Clusters Quickly.

Databricks Pools, a managed cache of virtual machine instances that enables clusters to start and scale 4 times faster.
Q8:B
Q9:D
Q10:IMAGE
Q11:CTumbling window functions are used to segment a data stream into distinct time segments and perform a function against them, such as the example below. The key differentiators of a Tumbling window are that they repeat, do not overlap, and an event cannot belong to more than one tumbling window.
Q12:DAnnotations are additional, informative tags that you can add to specific factory resources: pipelines, datasets, linked services, and triggers. By adding annotations, you can easily filter and search for specific factory resources.
