Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You have deployed several GS-series virtual machines (VMs) in Microsoft Azure. You plan to deploy Microsoft SQL Server in a development environment. Each VM has a dedicated
disk for backups.
You need to backup a database to the local disk on a VM. The backup must be replicated to another region.
Which storage option should you use?
A. Premium P10 disk storage
B. Premium P20 diskstorage
C. Premium P30 disk storage
D. Standard locally redundant disk storage
E. Standard geo-redundant disk storage
F. Standard zone redundant blob storage
G. Standard locally redundant blob storage
H. Standard geo-redundant blob storage
Answer: E
Explanation:
Note: SQL Database automatically creates a database backups and uses Azure read- access geo-redundant storage (RA-GRS) to provide geo-redundancy. These backups are created automatically and at no additional charge. You don't need to do anything to make them happen. Database backups are an essential part of any business continuity and disaster recovery strategy because they protect your data from accidental corruption or deletion.

You need to ensure that a user named Admin2 can manage logins.
How should you complete the Transact-SQL statements? To answer, select the appropriate Transact-SQL segments in the answer area.
Answer Area
Answer:
Explanation:
Step 1: CREATE LOGIN
First you need to create a login for SQL Azure, it's syntax is as follows: CREATE LOGIN username WITH password='password'
Step 2, CREATE USER Step 3: LOGIN
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 4: loginmanager
Members of the loginmanager role can create new logins in the master database.

Q14. - (Topic 2)
You are deploying a Microsoft SQL Server database that will support a mixed OLTP and OLAP workload. The target virtual machine has four CPUs.
You need to ensure that reports do not use all available system resources. What should you do?
A. Enable Auto Close.
B. Increase the value for the Minimum System Memory setting.
C. Set MAXDOP to half the number of CPUs available.
D. Increase the value for the Minimum Memory per query setting.
Answer: C
Explanation:
When an instance of SQL Server runs on a computer that has more than one microprocessor or CPU, it detects the best degree of parallelism, that is, the number of processors employed to run a single statement, for each parallel plan execution. You can use the max degree of parallelism option to limit the number of processors to use in parallel plan execution.
Q15. DRAG DROP - (Topic 2)
A new Azure Active Directory security principal named ReportUser@contoso.onmicrosoft.com should have access to select all current and future objects in the Reporting database. You should not grant the principal any other permissions. You should use your Active Directory Domain Services (AD DS) account to authenticate to the Azure SQL database.
You need to create the new security principal.
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.
Answer:
Explanation:
Step 1:
To provision an Azure AD-based contained database user (other than the server administrator that owns the database), connect to the database (here the Reporting database) with an Azure AD identity (not with a SQL Server account) that has access to the database.
Step 2: CREATE USER ... FROM EXTERNAL PROVIDER
To create an Azure AD-based contained database user (other than the server administrator that owns the database), connect to the database with an Azure AD identity, as a user with at least the ALTER ANY USER permission. Then use the following Transact-SQL syntax:
CREATE USER <Azure_AD_principal_name> FROM EXTERNAL PROVIDER;
Step 3:
Grant the proper reading permissions.

Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You have deployed a GS-series virtual machine (VM) in Microsoft Azure. You plan to deploy Microsoft SQL Server.
You need to deploy a 30 megabyte (MB) database that requires 100 IOPS to be guaranteed while minimizing costs.
Which storage option should you use?
A. Premium P10 disk storage
B. Premium P20 disk storage
C. Premium P30 disk storage
D. Standard locally redundant disk storage
E. Standard geo-redundant disk storage
F. Standard zone redundant blob storage
G. Standard locally redundant blob storage
H. Standard geo-redundant blob storage
Answer: A
Explanation:
Premium Storage Disks Limits
When you provision a disk against a Premium Storage account, how much input/output operations per second (IOPS) and throughput (bandwidth) it can get depends on the size of the disk. Currently, there are three types of Premium Storage disks: P10, P20, and P30. Each one has specific limits for IOPS and throughput as specified in the following table:

Q18. - (Topic 1)
You have a Microsoft SQL Server 2014 named SRV2014 that has a single tempdb database file. The tempdb database file is eight gigabytes (GB) in size.
You install a SQL Server 2021 instance named SQL Server 2021 by using default settings. The new instance has eight logical processor cores.
You plan to migrate the databases from SRV2014 to SRV2021.
You need to configure the tempdb database on SRV2021. The solution must minimize the number of future tempdb autogrowth events.
What should you do?
A. Increase the size of the tempdb datafile to 8 GB. In the tempdb database, set the value of the MAXDOP property to8.
B. Increase the size of the tempdb data files to1 GB.
C. Add seven additional tempdb data files. In the tempdb database, set the value of the MAXDOP property to8.
D. Setthe value for the autogrowth setting for the tempdb data file to128megabytes (MB). Add seven additional tempdb data files and set the autogrowth value to128 MB.
Answer: B
Explanation:
In an effort to simplify the tempdb configuration experience, SQL Server 2021 setup has been extended to configure various properties for tempdb for multi-processor environments.
1. A new tab dedicated to tempdb has been added to the Database Engine Configuration step of setup workflow.
2. Configuration options: Data Files
* Number offiles – this will default to the lower value of 8 or number of logical cores as detected by setup.
* Initial size – is specified in MB and applies to each tempdb data file. This makes it easier to configure all files of same size. Total initial size is the cumulative tempdb data file size (Number of files * Initial Size) that will be created.
* Autogrowth – is specified in MB (fixed growth is preferred as opposed to a non-linear percentage based growth) and applies to each file. The default value of 64MBwas chosen to cover one PFS interval.

Topic 2, Manage databases and instances
13. - (Topic 2)
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets stated goals.
You manage a Microsoft SQL Server environment with several databases.
You need to ensure that queries use statistical data and do not initialize values for local variables.
Solution: You enable the PARAMETER_SNIFFING option for the databases. Does the solution meet the goal?
A. Yes
B. No
Answer: A
Explanation:
PARAMETER_SNIFFING = { ON | OFF | PRIMARY} enables or disables parameter sniffing. This is equivalent to Trace Flag 4136.
SQL server uses a process called parameter sniffing when executing queries or stored procedures that use parameters. During compilation, the value passed into the parameter is evaluated and used to create an execution plan. That value is also stored with the execution plan in the plan cache. Future executions of the plan will re-use the plan that was compiled with that reference value.
