MCSA 70-765 Provisioning SQL Databases exam questions material

1. You administer a Microsoft SQL Server 2014 instance that has multiple databases. You have a two-node SQL Server failover cluster. The cluster uses a storage area network (SAN). You discover I/O issues. The SAN is at capacity and additional disks cannot be added.
You need to reduce the I/O workload on the SAN at a minimal cost.
What should you do?

2. You administer a Microsoft SQL Server 2014 database that includes a table named Application.Events. Application.Events contains millions of records about user activity in an application.
Records in Application.Events that are more than 90 days old are purged nightly. When records are purged, table locks are causing contention with inserts.
You need to be able to modify Application.Events without requiring any changes to the applications that utilize Application.Events.
Which type of solution should you use?

You plan to migrate Sales to Windows Azure SQL Database.
To do so, you need to implement a contained database.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)

4. You administer a Microsoft SQL Server 2014 database named Contoso on a server named Server01.
You need to track all SELECT statements issued in the Contoso database only by users in a role named Sales.
What should you create?

5. You administer a Microsoft SQL Server 2014 database named Contoso on a server named Server01.
You need to collect data for a long period of time to troubleshoot wait statistics when querying Contoso. You also need to ensure minimum impact to the server.
What should you create?

6. You plan to install Microsoft SQL Server 2014 for a web hosting company.
The company plans to host multiple web sites, each supported by a SQL Server database.
You need to select an edition of SQL Server that features backup compression of databases, basic data integration features, and low total cost of ownership.
Which edition should you choose?

7. You plan to install a Microsoft SQL Server 2014 instance.
The instance will support a database that has the following requirements:
Store Excel workbooks on the file system.
Access the workbooks through Transact-SQL.
Include the workbooks in database backups.
During installation, you need to ensure that the requirements will be met.
Which feature should you use?

8. You administer a Microsoft SQL Server 2014 instance named SQL2012. You are in the process of migrating a database from a SQL Server 2008 instance named SQL2008 to the SQL2012 instance.
You have upgraded a database from the SQL2008 instance by using the side-by-side migration technique.
You need to migrate the SQL Server logins from the SQL2008 instance to the SQL2012 instance.
What should you do?

9. You administer a Microsoft SQL Server 2014 database.
You have a SQL Server Agent job instance that runs using the service account. You have a job step within the job that requires elevated privileges.
You need to ensure that the job step can run using a different user account.
What should you use?

10. You have been hired as a Database Consultant by ABC.com to design a SQL Server 2014 database solution.
You are tasked with designing a scale-out and high-availability SQL Server 2014 Online Transaction Processing (OLTP) database solution that will maintain copies of data across two server instances.
Your solution must provide scale-out of read operations by distributing the reads from clients across two SQL Server 2014 nodes. The data in both SQL Server nodes needs to be indexed.
What should you include in your solution?

11. You are a database developer of a Microsoft SQL Server 2014 database. You are designing a table that will store Customer data from different sources. The table will include a column that contains the CustomerID from the source system and a column that contains the SourceID. A sample of this data is as shown in the following table.


You need to ensure that the table has no duplicate CustomerID within a SourceID. You also need to ensure that the data in the table is in the order of SourceID and then CustomerID.
Which Transact- SQL statement should you use?

12. You administer a Microsoft SQL Server 2014 database named ContosoDb.
Tables are defined as shown in the exhibit. (Click the Exhibit button.)


You need to display rows from the Orders table for the Customers row having the CustomerId value set to 1 in the following XML format.


Which Transact-SQL query should you use?

13. You administer a Microsoft SQL Server 2014 database named ContosoDb.
Tables are defined as shown in the exhibit. (Click the Exhibit button.)


You need to display rows from the Orders table for the Customers row having the CustomerId value set to 1 in the following XML format.


Which Transact-SQL query should you use?

14. You use Microsoft SQL Server 2014 to develop a database application. You need to implement a computed column that references a lookup table by using an INNER JOIN against another table.
What should you do?

15. You use a Microsoft SQL Server 2014 database that contains two tables named SalesOrderHeader and SalesOrderDetail.
The indexes on the tables are as shown in the exhibit. (Click the Exhibit button.)


You write the following Transact-SQL query:


You discover that the performance of the query is slow. Analysis of the query plan shows table scans where the estimated rows do not match the actual rows for SalesOrderHeader by using an unexpected index on SalesOrderDetail.
You need to improve the performance of the query.
What should you do?

16. You are a database developer for an application hosted on a Microsoft SQL Server 2014 server.
The database contains two tables that have the following definitions:


Global customers place orders from several countries. You need to view the country from which each customer has placed the most orders.
Which Transact-SQL query do you use?

17. You use Microsoft SQL Server 2014 to develop a database application. You need to create an object that meets the following requirements:
Which object should you use?

18. You administer a SQL Server 2014 server that contains a database named SalesDb. SalesDb contains a schema named Customers that has a table named Regions. A user named UserA is a member of a role named Sales. UserA is granted the Select permission on the Regions table. The Sales role is granted the Select permission on the Customers schema.
You need to ensure that the following requirements are met:
Which Transact-SQL statement should you use?

19. You develop a Microsoft SQL Server 2014 database that contains a heap named OrdersHistorical.
You write the following Transact-SQL query:
