NEW QUESTION # 273
You have an Azure subscription that contains a storage account. The account contains a blob container named blob1 and an Azure Synapse Analytics serverless SQL pool.
You need to query the CSV files stored in blob1. The solution must ensure that all the files in a folder named csv and all its subfolders are queried.
How should you complete the query? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

Explanation:
A computer screen shot of a computer code Description automatically generated

BULK Path (first dropdown):
* Correct Option: abfs:
* Since the storage account uses Azure Data Lake Storage Gen2, the abfs:// (Azure Blob File System) protocol is the correct option for accessing the files.
Path to Query Files:
* The path 'abfs://csv@acct1.blob.core.windows.net/blob1/' specifies the container (blob1) and the folder (csv) within the storage account.
* This ensures that all files in the csv folder and its subfolders are included in the query.
FORMAT (last dropdown):
* Correct Option: 'CSV'
* This indicates that the queried files are in the CSV format, which matches the requirement in the question.

NEW QUESTION # 274
What should you do to improve high availability of the real-time data processing solution?

A. Set Data Lake Storage to use geo-redundant storage (GRS).
B. Deploy a High Concurrency Databricks cluster.
C. Deploy an Azure Stream Analytics job and use an Azure Automation runbook to check the status of the job and to start the job if it stops.
D. Deploy identical Azure Stream Analytics jobs to paired regions in Azure.

Answer: D

Explanation:
Guarantee Stream Analytics job reliability during service updates
Part of being a fully managed service is the capability to introduce new service functionality and improvements at a rapid pace. As a result, Stream Analytics can have a service update deploy on a weekly (or more frequent) basis. No matter how much testing is done there is still a risk that an existing, running job may break due to the introduction of a bug. If you are running mission critical jobs, these risks need to be avoided. You can reduce this risk by following Azure's paired region model.
Scenario: The application development team will create an Azure event hub to receive real-time sales data, including store number, date, time, product ID, customer loyalty number, price, and discount amount, from the point of sale (POS) system and output the data to data storage in Azure Reference:
