Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have a database that includes a table named Candidate.
You need to update the statistics for a column named Skills in the table and turn off automatic statistics updates for the column.
Solution: You run the following query:

Does this meet the goal?

• A. NO
• B. YES

You administer a Microsoft SQL Server 2016 instance that contains a financial database hosted on a storage area network (SAN). The financial database has the following characteristics:
* A data file of 2 terabytes is located on a dedicated LUN (drive D).
* A transaction log of 10 GB is located on a dedicated LUN (drive E).
* Drive D has 1 terabyte of free disk space.
* Drive E has 5 GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday between
09:00 hours and 17:00 hours.
Five percent of the existing data is modified each day.
The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and
15:15 hours by using the BCP or BULK INSERT commands.
Each data load adds 3 GB of data to the database.
These data load operations must occur in the minimum amount of time. A full database backup is performed every Sunday at 10:00 hours.
Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.
You implement log shipping of the financial database to another SQL Server 2016 instance. You decide to failover to this secondary database.
You need to ensure that all transactions will be replicated to the secondary database.
Which backup option should you use?

• A. Differential
• B. BULK_LOGGED
• C. CONTINUE_AFTER_ERROR
• D. NO_CHECKSUM
• E. Transaction Log
• F. STANDBY
• G. CHECKSUM
• H. COPY_ONLY
• I. FULL
• J. DBO_ONLY
• K. NORECOVERY
• L. SIMPLE
• M. SKIP
• N. RESTART

General Overview
You are the Senior Database Administrator (DBA) for a software development company named Leafield Solutions. The company develops software applications custom designed to meet customer requirements.
Requirements Leafield Solutions has been asked by a customer to develop a web-based Enterprise Resource Planning and Management application. The new application will eventually replace a desktop application that the customer is currently using. The current application will remain in use while the users are trained to use the new webbased application.
You need to design the SQL Server and database infrastructure for the web-based application.
Databases
You plan to implement databases named Customers, Sales, Products, Current_Inventory, and TempReporting.
The Sales database contains a table named OrderTotals and a table named SalesInfo.
A stored procedure named SPUpdateSalesInfo reads data in the OrderTotals table and modifies data in the SalesInfo table.
The stored procedure then reads data in the OrderTotals table a second time and makes further changes to the information in the SalesInfo table.
The Current_Inventory database contains a large table named Inv_Current. The Inv_Current table has a clustered index for the primary key and a nonclustered index. The primary key column uses the identity property.
The data in the Inv_Current table is over 120GB in size. The tables in the Current_Inventory database are accessed by multiple queries in the Sales database.
Another table in the Current_Inventory database contains a self-join with an unlimited number of hierarchies.
This table is modified by a stored procedure named SPUpdate2.
An external application named ExternalApp1 will periodically query the Current_Inventory database to generate statistical information. The TempReporting database contains a single table named GenInfo.
A stored procedure named SPUPdateGenInfo combines data from multiple databases and generates millions of rows of data in the GenInfo table.
The GenInfo table is used for reports.
When the information in GenInfo is generated, a reporting process reads data from the Inv_Current table and queries information in the GenInfo table based on that data.
The GenInfo table is deleted after the reporting process completes. The Products database contains tables named ProductNames and ProductTypes.
Current System
The current desktop application uses data stored in a SQL Server 2005 database named DesABCopAppDB.
This database will remain online and data from the Current_Inventory database will be copied to it as soon as data is changed in the Current_Inventory database.
SQL Servers
A new SQL Server 2012 instance will be deployed to host the databases for the new system. The databases will be hosted on a Storage Area Network (SAN) that provides highly available storage.
Design Requirements
Your SQL Server infrastructure and database design must meet the following requirements:
* Confidential information in the Current_ Inventory database that is accessed by ExternalApp1 must be securely stored.
* Direct access to database tables by developers or applications must be denied.
* The account used to generate reports must have restrictions on the hours when it is allowed to make a connection.
* Deadlocks must be analyzed with the use of Deadlock Graphs.
* In the event of a SQL Server failure, the databases must remain available.
* Software licensing and database storage costs must be minimized.
* Development effort must be minimized.
* The Tempdb databases must be monitored for insufficient free space.
* Failed authentication requests must be logged.
* Every time a new row is added to the ProductTypes table in the Products database, a user defined function that validates the row must be called before the row is added to the table.
* When SPUpdateSalesInfo queries data in the OrderTotals table the first time, the same rows must be returned along with any newly added rows when SPUpdateSalesInfo queries data in the OrderTotals table the second time.
You need to enable users to modify data in the database tables using UPDATE operations.
You need to implement a solution that meets the design requirements.
What should you configure?

• A. You should configure a database role.
• B. You should configure a server role.
• C. You should configure stored procedures that use the EXECUTE AS statement.
• D. You should configure functions that use the EXECUTE AS statement.

You have a database named DB1 that contains the primary file group and two other file groups named CurrectData and HistoricalData. CurrentData contains 320 GB of active data that is updated frequently.
HistoricalData is read-only and contains 1.7 TB of data.
You have a backup schedule configured as show in the following table.

DB1 fails at 08:42 on Monday. You deploy a new server.
You need to recover CurrentData as quickly as possible on the new server. The solution must minimize the amount of data loss.
Which four statements should you execute in sequence? To answer, move the appropriate statements from the list of statements to the answer area and arrange them in the correct order.

You plan to integrate an on-premises Microsoft SQL Server environment with Microsoft Azure.
You need to create the authentication object so that you can connect to Azure.
Which Windows PowerShell command or commands should you run?

• A. Invoke-Sqlcmd "CREATE EXTERNAL DATA SOURCE MyAzureStorage WITH (LOCATION =
  'wasbs://[email protected]/", CREDENTIAL = Pa$$w0rd)"
• B. Invoke-Sqlcmd "CREATE LOGIN AzureCred WITH CREDENTIAL = 'AzureKey', PASSWORD =
  'Pa$$w0rd"
• C. Invoke-Sqlcmd "CREATE CREDENTIAL AzureCred WITH IDENTITY = 'AzureKey', SECRET =
  'Pa$$w0rd"
