Question 91

DRAG DROP
You have an Azure SQL Database instance named DatabaseA on a server named Server1.
You plan to add a new user named App1 to DatabaseA and grant App1 db_datacenter permissions. App1 will
use SQL Server Authentication.
You need to create App1. The solution must ensure that App1 can be given access to other databases by using
the same credentials.
Which three actions should you perform 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:

Section: [none]
Explanation:
Step 1: On the master database, run CREATE LOGIN [App1] WITH PASSWORD = 'p@aaW0rd!'
Logins are server wide login and password pairs, where the login has the same password across all databases.
Here is some sample Transact-SQL that creates a login:
CREATE LOGIN readonlylogin WITH password='1231!#ASDF!a';
You must be connected to the master database on SQL Azure with the administrative login (which you get from
the SQL Azure portal) to execute the CREATE LOGIN command.
Step 2: On DatabaseA, run CREATE USER [App1] FROM LOGIN [App1]
Users are created per database and are associated with logins. You must be connected to the database in
where you want to create the user. In most cases, this is not the master database. Here is some sample
Transact-SQL that creates a user:
CREATE USER readonlyuser FROM LOGIN readonlylogin;
Step 3: On DatabaseA run ALTER ROLE db_datareader ADD Member [App1]
Just creating the user does not give them permissions to the database. You have to grant them access. In the
Transact-SQL example below the readonlyuser is given read only permissions to the database via the
db_datareader role.
EXEC sp_addrolemember 'db_datareader', 'readonlyuser';

Question 92

You have an Azure virtual machine based on a custom image named VM1.
VM1 hosts an instance of Microsoft SQL Server 2019 Standard.
You need to automate the maintenance of VM1 to meet the following requirements:
Automate the patching of SQL Server and Windows Server.
Automate full database backups and transaction log backups of the databases on VM1.
Minimize administrative effort.
What should you do first?

Correct Answer: B
Automated Patching depends on the SQL Server infrastructure as a service (IaaS) Agent Extension. The SQL Server IaaS Agent Extension (SqlIaasExtension) runs on Azure virtual machines to automate administration tasks. The SQL Server IaaS extension is installed when you register your SQL Server VM with the SQL Server VM resource provider.

Question 93

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 have an Azure SQL database named Sales.
You need to implement disaster recovery for Sales to meet the following requirements:
* During normal operations, provide at least two readable copies of Sales.
* Ensure that Sales remains available if a datacenter fails.
Solution: You deploy an Azure SQL database that uses the General Purpose service tier and geo-replication.
Does this meet the goal?

Correct Answer: B
Section: [none]
Explanation:
Instead deploy an Azure SQL database that uses the Business Critical service tier and Availability Zones.
Note: Premium and Business Critical service tiers leverage the Premium availability model, which integrates
compute resources (sqlservr.exe process) and storage (locally attached SSD) on a single node. High
availability is achieved by replicating both compute and storage to additional nodes creating a three to four-
node cluster.
By default, the cluster of nodes for the premium availability model is created in the same datacenter. With the
introduction of Azure Availability Zones, SQL Database can place different replicas of the Business Critical
database to different availability zones in the same region. To eliminate a single point of failure, the control ring
is also duplicated across multiple zones as three gateway rings (GW).

Question 94

You have an on-premises Microsoft SQL Server 2016 server named Server1 that contains a database named DB1.
You need to perform an online migration of DB1 to an Azure SQL Database managed instance by using Azure Database Migration Service.
How should you configure the backup of DB1? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:

insert code

Question 95

You have an Azure Stream Analytics job.
You need to ensure that the job has enough streaming units provisioned.
You configure monitoring of the SU % Utilization metric.
Which two additional metrics should you monitor? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

Correct Answer: C,D
Section: [none]
Explanation:
To react to increased workloads and increase streaming units, consider setting an alert of 80% on the SU Utilization metric. Also, you can use watermark delay and backlogged events metrics to see if there is an impact.
Note: Backlogged Input Events: Number of input events that are backlogged. A non-zero value for this metric implies that your job isn't able to keep up with the number of incoming events. If this value is slowly increasing or consistently non-zero, you should scale out your job, by increasing the SUs.
