Provisioning SQL Databases

Question No: 11 – (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?

  1. Yes

  2. 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:

{

quot;$schemaquot;: quot;http://schema.management.azure.com/schemas/2015-01- 01/deploymentTemplate.json#quot;,

quot;contentVersionquot;: quot;quot;, quot;parametersquot;: { },

quot;variablesquot;: { },

quot;resourcesquot;: [ ],

quot;outputsquot;: { }

}

Topic 2, Manage databases and instances

Question No: 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 QUERY_OPTIMIZER_HOTFIXES option for the databases. Does the solution meet the goal?

  1. Yes

  2. No

Answer: B Explanation:

QUERY_OPTIMIZER_HOTFIXES = { ON | OFF | PRIMARY } enables or disables query optimization hotfixes regardless of the compatibility level of the database. This is equivalent to Trace Flag 4199.

Question No: 14 – (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?

  1. Enable Auto Close.

  2. Increase the value for the Minimum System Memory setting.

  3. Set MAXDOP to half the number of CPUs available.

  4. 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.

Question No: 15 – (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?

  1. Yes

  2. 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.

Question No: 16 – (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 LEGACY_CARDINALITY_ESTIMATION option for the databases. Does the solution meet the goal?

  1. Yes

  2. No

Answer: B Explanation:

LEGACY_CARDINALITY_ESTIMATION = { ON | OFF | PRIMARY }

Enables you to set the query optimizer cardinality estimation model to the SQL Server 2012 and earlier version independent of the compatibility level of the database. This is equivalent to Trace Flag 9481.

Question No: 17 – (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?

  1. Create an In-Memory table.

  2. Increase the storage limit in the pool.

  3. Implement a readable secondary database.

  4. 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#39;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

Question No: 18 – (Topic 2)

You manage a Microsoft SQL Server environment in a Microsoft Azure virtual machine. You must enable Always Encrypted for columns in a database.

You need to configure the key store provider.

What should you do?

  1. Manually specify the column master key.

  2. Modify the connection string for applications.

  3. Auto-generate a column master key.

  4. Use theWindows certificate store.

Answer: D Explanation:

Always Encrypted supports multiple key stores for storing Always Encrypted column master keys. A column master key can be a certificate stored in Windows Certificate Store.

References:https://msdn.microsoft.com/en-us/library/mt723359.aspx

Question No: 19 DRAG DROP – (Topic 2)

You deploy a new Microsoft Azure SQL Database instance to support a variety of mobile applications and public websites. You plan to create a new security principal named User1.

The principal must have access to select all current and future objects in a database named Reporting. The activity and authentication of the database user must be limited to the Reporting 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.

Step 1, Step 2:

First you need to create a login for SQL Azure, it#39;s syntax is as follows: CREATE LOGIN username WITH password=#39;password#39;;

This command needs to run in master db. Only afterwards can you run commands to create a user in the database.

Step 3:

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;

Question No: 20 – (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?

  1. transport-level encryption

  2. cell-level encryption

  3. Transparent Data Encryption

  4. Always Encrypted

  5. Encrypting File System

  6. BitLocker

  7. 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.
