What configuration changes should you implement? To answer, select the appropriate option from each list in the answer area.
正確答案:
Explanation:
From the scenario: SRV1 has 16 logical cores and hosts a SQL Server instance that supports a mission-critical application. The application hasapproximately 30,000 concurrent users and relies heavily on the use of temporary tables.
Box 1: Change the size of the tempdb log file.
The size and physical placement of the tempdb database can affect the performance of a system. For example, if the size that is defined for tempdb is too small, part of the system-processing load may be taken up with autogrowing tempdb to the size required to support the workload every time you restart the instance of SQL Server. You can avoid this overhead by increasing the sizes of the tempdb data and log file.
Box 2: Add additional tempdb files.
Create as many files as needed to maximize disk bandwidth. Using multiple files reduces tempdb storage contention and yields significantly better scalability. However, do not create too many files because this can reduce performance and increase management overhead. As a general guideline, create one data file for each CPU on the server (accounting for any affinity mask settings) and then adjust the number of files up or down as necessary.
Topic 2, Contoso, Ltd Case Study
Background
You are the database administrator for Contoso, Ltd. The company has 200 offices around the world. The company has corporate executives that are located in offices in London, New York, Toronto, Sydney, and Tokyo.
Contoso, Ltd. has a Microsoft Azure SQL Database environment. You plan to deploy a new Azure SQL Database to support a variety of mobile applications and public websites.
The company is deploying a multi-tenant environment. The environment will host Azure SQL Database instances. The company plans to make the instances available to internal departments and partner companies. Contoso is in the final stages of setting up networking and communications for the environment.
Existing Contoso and Customer instances need to be migrated to Azure virtual machines (VM) according to the following requirements:
The company plans to deploy a new order entry application and a new business intelligence and analysis application. Each application will be supported by a new database. Contoso creates a new Azure SQL database named Reporting. The database will be used to support the company's financial reporting requirements. You associate the database with the Contoso Azure Active Directory domain.
Each location database for the data entry application may have an unpredictable amount of activity. Data must be replicated to secondary databases in Azure datacenters in different regions.
To support the application, you need to create a database named contosodb1 in the existing environment.

A company has an on-premises Microsoft SQL Server 2016 environment. All futures databases must meet the following requirements:
The recovery model must be set to simple.
The compatibility level must be set to SQL server 2014 (120).
Your need to configure the SQL server 2016 environment.
In the table below, identify the database you must modify for each requirement.
The recovery model must be set to simple.
The compatibility level must be set to SQL server 2014 (120).
Your need to configure the SQL server 2016 environment.
In the table below, identify the database you must modify for each requirement.
正確答案:
Explanation:
Model: Change from full to simple Recovery Model
Newly created user databases use the same recovery model as the model database.
The model database is used as the template for all databases created on an instance of SQL Server. Because tempdb is created every time SQL Server is started, the model database must always exist on a SQL Server system. The entire contents of the model database, including database options, are copied to the new database.
Model: Set compatibility level to 120
For all installations of SQL Server, the default compatibility level is set to the version of the Database Engine. Databases are set to this level unless the model database has a lower compatibility level.

正確答案:
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.

Background
You manage the Microsoft SQL Server environment for a company that manufactures and sells automobile parts.
The environment includes the following servers: SRV1 and SRV2. SRV1 has 16 logical cores and hosts a SQL Server instance that supports a mission-critical application. The application has approximately 30,000 concurrent users and relies heavily on the use of temporary tables.
The environment also includes the following databases: DB1, DB2, and Reporting. The Reporting database is protected with Transparent Data Encryption (TDE). You plan to migrate this database to a new server. You detach the database and copy it to the new server.
You are performing tuning on a SQL Server database instance. The application which uses the database was written using an object relationship mapping (ORM) tool which maps tables as objects within the application code. There are 30 stored procedures that are regularly used by the application.
After reviewing the plan cache you have identified that a large number of simple queries are using parallelism, and that execution plans are not being kept in the plan cache for very long.
You review the properties of the instance (Click the Exhibit button).
