You receive alerts indicating that there are insufficient resources.
From the Activity Windows list in the Monitoring and Management app, you discover the statuses described in the following table.
Which activity cannot complete because of insufficient resources?

Answer: C
QUESTION 25
Note: This question is part of a series of questions that present the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
Start of repeated scenario
You are migrating an existing on-premises data warehouse named LocalDW to Microsoft Azure. You will use an Azure SQL data warehouse named AzureDW for data storage and an Azure Data Factory named AzureDF for extract, transformation, and load (ETL) functions.
For each table in LocalDW, you create a table in AzureDW.
On the on-premises network, you have a Data Management Gateway.
Some source data is stored in Azure Blob storage. Some source data is stored on an on- premises Microsoft SQL Server instance. The instance has a table named Table1.
After data is processed by using AzureDF, the data must be archived and accessible forever. The archived data must meet a Service Level Agreement (SLA) for availability of 99 percent. If an Azure region fails, the archived data must be available for reading always. The storage solution for the archived data must minimize costs.
End of repeated scenario.
You need to define the schema of Table1 in AzureDF.
What should you create?
A. a gateway
B. a linked service
C. a dataset
D. a pipeline
Answer: C
QUESTION 26
You are developing an application by using the Microsoft .NET SDK. The application will access data from a Microsoft Azure Data Lake folder.
You plan to authenticate the application by using service-to-service authentication.
You need to ensure that the application can access the Data Lake folder.
Which three actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. Register an Azure Active Directory app that uses the Web app/API application type.
B. Configure the application to use the application ID, authentication key, and tenant ID.
C. Assign the Azure Active Directory app permission to the Data Lake Store folder.
D. Configure the application to use the OAuth 2.0 token endpoint.
E. Register an Azure Active Directory app that uses the Native application type.
F. Configure the application to use the application ID and redirect URI.
Answer: ABC

QUESTION 27
You ingest data into a Microsoft Azure event hub.
You need to export the data from the event hub to Azure Storage and to prepare the data for batch processing tasks in Azure Data Lake Analytics.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. Run the Avro extractor from a U-SQL script.
B. Create an Azure Storage account.
C. Add a shared access policy.
D. Enable Event Hubs Archive.
E. Run the CSV extractor from a U-SQL script.
Answer: BD
QUESTION 28
You are creating a Data Factory workflow.
The workflow must run a stored procedure from a SQL database, perform a Hive query, and copy data from an on-premises SQL database into an Azure SQL database.
These steps must be managed and performed as an atomic unit.
You need to configure the workflow.
Which Data Factory entity should you use?
A. Dataset
B. Linked service
C. Activity
D. Pipeline
Answer: D
QUESTION 29
You are designing an Azure Data Lake managed cluster for your organization’s realtime data processing.
The streaming data could range from 10 MB to 100 GB per message.
You need to choose the correct storage model to store this data.
Which storage model should you use?
A. Block Blobs
B. Page Blobs
C. HBase
D. Azure Storage Queues
Answer: A
QUESTION 30

You need to load the data to the data warehouse in the least amount of time possible.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. Use Microsoft SQL Server Integration Services (SSIS) to enumerate from the Data Lake Store by using a for loop.
B. Use AzCopy to export the files from the Data Lake Store to Azure Blob storage.
C. For each file in the loop, export the data to Parallel Data Warehouse by using a Microsoft SQL Server Native Client destination.
D. Load the data by executing the CREATE TABLE AS SELECT statement.
E. Use bcp to import the files.
F. In the data warehouse, configure external tables and external file formats that correspond to the Data Lake Store.
Answer: DF

QUESTION 32
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
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 monitoring user queries to a Microsoft Azure SQL data warehouse that has six compute nodes.
You discover that compute node utilization is uneven. The rows_processed column from sys.dm_pdw_workers shows a significant variation in the number of rows being moved among the distributions for the same table for the same query.
You need to ensure that the load is distributed evenly across the compute nodes.
Solution: You add a clustered columnstore index.
Does this meet the goal?
A. Yes
B. No
Answer: B
