Q1. - (Topic 1)
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.
Your company plans to use Microsoft Azure Resource Manager templates for all future deployments of SQL Server on Azure virtual machines.
You need to create the templates.
Solution: You use Visual Studio to create a XAML template that defines the deployment and configuration settings for the SQL Server environment.
Does the solution meet the goal?
A. Yes
B. No
Answer: B
Explanation:
Azure ResourceManager template consists of JSON, not XAML, and expressions that you can use to construct values for your deployment.
A good JSON editor can simplify the task of creating templates.
Note: In its simplest structure, an Azure Resource Manager template contains the following elements:
{
"$schema": "http://schema.management.azure.com/schemas/2015-01- 01/deploymentTemplate.json#",
"contentVersion": "", "parameters": { },
"variables": { },
"resources": [ ],
"outputs": { }
}

Q3. 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.

Q4. - (Topic 2)
You plan to deploy 20 Microsoft Azure SQL Database instances to an elastic pool in Azure to support a batch processing application.
Two of the databases in the pool reach their peak workload threshold at the same time every day. This leads to inconsistent performance for batch completion.
You need to ensure that all batches perform consistently. What should you do?
A. Create an In-Memory table.
B. Increase the storage limit in the pool.
C. Implement a readable secondary database.
D. Increase the total number of elastic Database Transaction Units (eDTUs) in the pool.
Answer: D
Explanation:
In SQL Database, the relative measure of a database's ability tohandle resource demands is expressed in Database Transaction Units (DTUs) for single databases and elastic DTUs (eDTUs) for databases in an elastic pool.
A pool is given a set number of eDTUs, for a set price. Within the pool, individual databases are given the flexibility to auto-scale within set parameters. Under heavy load, a database can consume more eDTUs to meet demand.
Additional eDTUs can be added to an existing pool with no database downtime. References:https://docs.microsoft.com/en-us/azure/sql-database/sql-database-elastic-pool
Q5. - (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.

Q6. DRAG DROP - (Topic 1)
You are building a new Always On Availability Group in Microsoft Azure. The corporate domain controllers (DCs) are attached to a virtual network named ProductionNetwork. The DCs are part of an availability set named ProductionServers1.
You create the first node of the availability group and add it to an availability set named ProductionServers2. The availability group node is a virtual machine (VM) that runs Microsoft SQL Server. You attach the node to ProductionNetwork.
The servers in the availability group must be directly accessible only by other company VMs in Azure.
You need to configure the second SQL Server VM for the availability group.
How should you configure the VM? To answer, drag the appropriate configuration settings to the correct target locations. Each configuration setting may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation;
Box 1: ProductionNetwork
The virtual network is named ProductionNetwork.
Box 2: None /Not Assigned
As the servers in the availability group must be directly accessible only by other company VMs in Azure, there should be no Public IP address.
Box 3: ProductionServer2
You create the first node of the availability group and add it to an availability set named ProductionServers2. The availability group node is a virtual machine (VM) that runs Microsoft SQL Server.
Q7. - (Topic 2)
Note: This questions 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 deploy Microsoft SQL Server to a virtual machine in Azure. You distribute the database files and filegroups across multiple Azure storage disks.
You must be able to manage the databases as individual entities by using SQL Server Management Studio. All data in the databases must be stored encrypted. Backups must be encrypted by using the same key as the live copy of the database.
You need to secure the data. What should you implement?
A. transport-level encryption
B. cell-level encryption
C. Transparent Data Encryption
D. Always Encrypted
E. Encrypting File System
F. BitLocker
G. dynamic data masking
Answer: C
Explanation:
Transparent data encryption (TDE) encrypts your databases, associated backups, and transaction log files at rest without requiring changes to your applications.
TDE encrypts the storage of an entire database by using a symmetric key called the database encryption key. In SQL Database the database encryption key is protected by a built-in server certificate. The built-in server certificate is unique for each SQL Database server.

Q8. HOTSPOT - (Topic 1)
You plan to migrate a Microsoft SQL Server workload from an on-premises server to a Microsoft Azure virtual machine (VM). The current server contains 4 cores with an average
CPU workload of 6 percent and a peak workload of 10 percent when using 2.4Ghz processors.
You gather the following metrics:
You need to design a SQL Server VM to support the migration while minimizing costs. For each setting, which value should you use? To answer, select the appropriate storage
option from each list in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Data drive: Premium Storage Transaction log drive: Standard Storage TempDB drive: Premium Storage
Note: A standard disk is expected to handle 500 IOPS or 60MB/s. A P10 Premium disk is expected to handle 500 IOPS.
A P20 Premium disk is expected to handle 2300 IOPS. A P30 Premium disk is expected to handle 5000 IOPS.
VM size: A3
Max data disk throughput is 8x500 IOPS

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.

Q9. HOTSPOT - (Topic 2)
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.

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.
