B.

Azure Blob storage


C.

Azure IoT Hub


D.

Azure Event Hubs





B.
  

Azure Blob storage

You have a table in an Azure Synapse Analytics dedicated SQL pool. The table was created by using the following Transact-SQL statement.

You need to alter the table to meet the following requirements:
Ensure that users can identify the current manager of employees.
Support creating an employee reporting hierarchy for your entire company.
Provide fast lookup of the managers’ attributes such as name and job title.
Which column should you add to the table?

[ManagerEmployeeID] [int] NULL


B.

[ManagerEmployeeID] [smallint] NULL


C.

[ManagerEmployeeKey] [int] NULL


D.

[ManagerName] [varchar](200) NULL





A.

You are designing a fact table named FactPurchase in an Azure Synapse Analytics dedicated SQL pool. The table contains purchases from suppliers for a retail store. FactPurchase will contain the following columns.

FactPurchase will have 1 million rows of data added daily and will contain three years of
data.
Transact-SQL queries similar to the following query will be executed daily.
SELECT
SupplierKey, StockItemKey, COUNT(*)
FROM FactPurchase
WHERE DateKey >= 20210101
AND DateKey <= 20210131
GROUP By SupplierKey, StockItemKey
Which table distribution will minimize query times?


A.

round-robin


B.

replicated


C.

hash-distributed on DateKey


D.

hash-distributed on PurchaseKey





D.
  

hash-distributed on PurchaseKey



Hash-distributed tables improve query performance on large fact tables, and are the focus
of this article. Round-robin tables are useful for improving loading speed.

You are designing an inventory updates table in an Azure Synapse Analytics dedicated
SQL pool. The table will have a clustered columnstore index and will include the following
columns:
• EventDate: 1 million per day
• EventTypelD: 10 million per event type
• WarehouselD: 100 million per warehouse
ProductCategoryTypeiD: 25 million per product category type
You identify the following usage patterns:
Analyst will most commonly analyze transactions for a warehouse.
Queries will summarize by product category type, date, and/or inventory event type.
You need to recommend a partition strategy for the table to minimize query times.
On which column should you recommend partitioning the table?


A.

ProductCategoryTypeID


B.

EventDate


C.

WarehouseID
