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 are migrating a set of databases from an existing Microsoft SQL Server instance to a new instance.
You need to complete the migration while minimizing administrative effort and downtime.
Which should you implement?

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 plan the SQL Server 2012 deployment that meets the design requirements.
Which of the following steps should you perform?

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?

Which feature should you enable and configure so session requests addressed to a specific instance can be allocated to different processor resources based on session request properties?

You have the following servers:

SQL1 hosts a database named DB1.
Users in the branch office must be able to access DB1 from SQL3.
You need to configure log shipping on DB1 from the main office to the branch office.
On which server should you configure the backup job?

After you answer a question in this section, you will NOT be able to return to it As a result, these questions will not appear in the review screen.
You support an application that stores data in a Microsoft SQL Server database. You have a query that returns data for a report that users run frequently.
The query optimizer sometimes generates a poorly-performing plan for the query when certain parameters are used. You observe that this is due to the distribution of data within a specific table that the query uses.
You need to ensure that the query optimizer always uses the query plan that you prefer.
Solution: You create a plan guide for the query by using the desired query plan and the sp_create_plan_guide stored procedure.
Does the solution meet the goal?

You have a database named Saleshistory that records sales transactions for your organization. You create indexes in the database.
The database has grown over time and now contains hundreds of indexes.
You need to identify the indexes that are not being used.
Which dynamic management object should you use?

Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
You are a database administrator for a company that has an on-premises Microsoft SQL Server environment and Microsoft Azure SQL Database instances. The environment hosts several customer databases, and each customer uses a dedicated instance. The environments that you manage are shown in the following table.

You need to configure auditing for WDWDB.
In the table below, identify the event type that you must audit for each activity.

You use SQL Server 2014.
You need to create a single object that inserts a provided value into Table1, and then returns a count of the records in Table1.
Develop the solution by selecting and arranging the required code blocks in the correct order. You may not need all of the code blocks.

Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the next of the scenario is exactly the same in each question in this series.
Start of repeated scenario
Contoso, Ltd. has Microsoft SQL Server databases that support a custom application. The current SQL Server environment consists of two servers: ContosoSQL1 and ContosoSQL2. These two servers participate in an Always On Availability Group named ContosoAG1 that is configured to use synchronous-commit with automatic failover. The secondary replica is not configured for read-only access.
The application performs both transactional processing and historical data retrieval in a database named ContosoDB. The application includes an inventory management module. The inventory management module and database have experienced performance issues.
Users report that a query named InventoryQuery1 takes a long time to complete. The query is shown as follows:
SELECT ProductNumber, Name, ProductLine
FROM Production.Product
WHERE ProductNumber = N'<specific product>'
The query plan used by SQL Server for this query is shown in the exhibit. (Click the Exhibit tab.) Various performance issues, including frequent long-term blocking episodes, prevent business users from completing their daily tasks. You suspect the tempdb database resources could be responsible. You must create Blocking reports for the ContosoDB database to identify issues.
Exhibit.

You plan to use Extended Events to review all Transact-SQL statements that are run against the ContosoSQL1 instance. The output from the Extended Events session must contain both start and stop events and must be written to a file. You must configure the Extended Events session to minimize possible data loss and reduce the effect on server performance.
You plan to deploy an additional secondary replica named ContosoSQL3 to ContosoAG1. Read-only traffic must be load-balanced between the two secondary replicas, regardless of which instance is the primary replica.
Contoso plans to add an additional dedicated reporting system that will rely on real-time data from the transactional databases.
End of repeated scenario
You need to create the blocking reports.
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.

Overview
General Overview
ADatum Corporation has offices in Miami and Montreal.
The network contains a single Active Directory forest named adatum.com. The offices connect to each other by using a WAN link that has 5-ms latency.
A: Datum standardizes its database platform by using SQL Server
2014 Enterprise edition.
Databases
Each office contains databases named Sales, Inventory, Customers, Products, Personnel, and Dev.
Servers and databases are managed by a team of database administrators. Currently, all of the database administrators have the same level of permissions on all of the servers and all of the databases.
The Customers database contains two tables named Customers and Classifications.
The following graphic shows the relevant portions of the tables:

The following table shows the current data in the Classifications table:

The Inventory database is updated frequently.
The database is often used for reporting.
A full backup of the database currently takes three hours to complete.
Stored Procedures
A stored procedure named USP_1 generates millions of rows of data for multiple reports. USP_1 combines data from five different tables from the Sales and Customers databases in a table named Table1.
After Table1 is created, the reporting process reads data from Table1 sequentially several times. After the process is complete, Table1 is deleted.
A stored procedure named USP_2 is used to generate a product list. The product list contains the names of products grouped by category.
USP_2 takes several minutes to run due to locks on the tables the procedure accesses. The locks are caused by USP_1 and USP_3.
A stored procedure named USP_3 is used to update prices. USP_3 is composed of several UPDATE statements called in sequence from within a transaction.
Currently, if one of the UPDATE statements fails, the stored procedure fails. A stored procedure named USP_4 calls stored procedures in the Sales, Customers, and Inventory databases.
The nested stored procedures read tables from the Sales, Customers, and Inventory databases. USP_4 uses an EXECUTE AS clause.
All nested stored procedures handle errors by using structured exception handling. A stored procedure named USP_5 calls several stored procedures in the same database. Security checks are performed each time USP_5 calls a stored procedure.
You suspect that the security checks are slowing down the performance of USP_5. All stored procedures accessed by user applications call nested stored procedures.
The nested stored procedures are never called directly.
Design Requirements
Data Recovery
You must be able to recover data from the Inventory database if a storage failure occurs. You have a Recovery Time Objective (RTO) of 5 minutes.
You must be able to recover data from the Dev database if data is lost accidentally. You have a Recovery Point Objective (RPO) of one day.
Classification Changes
You plan to change the way customers are classified. The new classifications will have four levels based on the number of orders. Classifications may be removed or added in the future. Management requests that historical data be maintained for the previous classifications. Security A group of junior database administrators must be able to manage security for the Sales database. The junior database administrators will not have any other administrative rights.
A: Datum wants to track which users run each stored procedure.
Storage
ADatum has limited storage. Whenever possible, all storage space should be minimized for all databases and all backups.
Error Handling
There is currently no error handling code in any stored procedure.
You plan to log errors in called stored procedures and nested stored procedures. Nested stored procedures are never called directly.
You need to recommend a solution to minimize the amount of time it takes to execute USP_2. What should you recommend?

Your company hosts Microsoft SQL Server instances for customers. One customer requires that the SQL Server instance send an email when an alert is generated in the Sales database.
You need to create the alert.
How should you complete the Transact-SQL statement? To answer, select the appropriate options in the answer area.
