Q1.  - (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

Q2. - (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.

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 JSON template that defines the deployment and configuration settings for the SQL Server environment.

Does the solution meet the goal?

A. Yes

B. No

Answer: A

Explanation:

Azure Resource Manager 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": { }

Q5. 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.

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:

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.
