You plan to enable Azure Multi-Factor Authentication (MFA).
You need to ensure that [email protected] can manage any databases hosted on an Azure SQL server named SQL10543936 by signing in using his Azure Active Directory (Azure AD) user account.
To complete this task, sign in to the Azure portal.



Answer : See the explanation below.

Explanation:
Provision an Azure Active Directory administrator for your managed instance
Each Azure SQL server (which hosts a SQL Database or SQL Data Warehouse) starts with a single server administrator account that is the administrator of the entire Azure SQL server. A second SQL Server administrator must be created, that is an Azure AD account. This principal is created as a contained database user in the master database.
1. In the Azure portal, in the upper-right corner, select your connection to drop down a list of possible Active Directories. Choose the correct Active Directory as the default Azure AD. This step links the subscription-associated Active Directory with Azure SQL server making sure that the same subscription is used for both
Azure AD and SQL Server. (The Azure SQL server can be hosting either Azure SQL Database or Azure SQL Data Warehouse.)


2. Search for and select the SQL server SQL10543936

3. In SQL Server page, select Active Directory admin.
4. In the Active Directory admin page, select Set admin.

5. In the Add admin page, search for user [email protected], select it, and then select Select. (The Active Directory admin page shows all members and groups of your Active Directory. Users or groups that are grayed out cannot be selected because they are not supported as Azure AD administrators.

6. At the top of the Active Directory admin page, select SAVE.

HOTSPOT -
You have the following Azure Stream Analytics query.


For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:



Answer :

Explanation:

Box 1: No -
Note: You can now use a new extension of Azure Stream Analytics SQL to specify the number of partitions of a stream when reshuffling the data.
The outcome is a stream that has the same partition scheme. Please see below for an example:
WITH step1 AS (SELECT * FROM [input1] PARTITION BY DeviceID INTO 10), step2 AS (SELECT * FROM [input2] PARTITION BY DeviceID INTO 10)
SELECT * INTO [output] FROM step1 PARTITION BY DeviceID UNION step2 PARTITION BY DeviceID
Note: The new extension of Azure Stream Analytics SQL includes a keyword INTO that allows you to specify the number of partitions for a stream when performing reshuffling using a PARTITION BY statement.

Box 2: Yes -
When joining two streams of data explicitly repartitioned, these streams must have the same partition key and partition count.

Box 3: Yes -
Streaming Units (SUs) represents the computing resources that are allocated to execute a Stream Analytics job. The higher the number of SUs, the more CPU and memory resources are allocated for your job.
In general, the best practice is to start with 6 SUs for queries that don't use PARTITION BY.
Here there are 10 partitions, so 6x10 = 60 SUs is good.
Note: Remember, Streaming Unit (SU) count, which is the unit of scale for Azure Stream Analytics, must be adjusted so the number of physical resources available to the job can fit the partitioned flow. In general, six SUs is a good number to assign to each partition. In case there are insufficient resources assigned to the job, the system will only apply the repartition if it benefits the job.
