You administer a Microsoft SQL Server 2012 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?

You are a database administrator for a Microsoft SQL Server 2012 environment.
You want to deploy a new application that will scale out the workload to at least five different SQL Server instances.
You need to ensure that for each copy of the database, users are able to read and write data that will then be synchronized between all of the database instances.
Which feature should you use?

You administer two Microsoft SQL Server 2012 servers named ProdSrv1 and ProdSrv2. ProdSrv1 is configured as a Distributor. Both servers are configured to use
the Windows NT Service virtual accounts for all SQL Services.
You are configuring snapshot replication from ProdSrv1 to ProdSrv2 by using ProdSrv2 as a pull subscriber.
The distribution agent on ProdSrv2 regularly fails, displaying the following error message:
“Cannot access the file. Operating system error code 5 (Access is denied.).” You need to configure the distribution agent by granting only the minimum required

access to all accounts.
What should you do?

You are a database administrator for a Microsoft SQL Server 2012 database named AdventureWorks2012.
You create an Availability Group defined by the following schema. (Line numbers are included for reference only.)

You need to implement an AlwaysOnAvailablity Group that will meet the following conditions:
Production transactions should be minimally affected. The secondary server should allow reporting queries to be performed. If the primary server goes offline, the
secondary server should not automatically take over.

Which Transact-SQL statement should you insert at line 06?

You administer a Microsoft SQL Server 2012 database. You want to make a full backup of the database to a file on disk.
In doing so, you need to output the progress of the backup.
Which backup option should you use?

You administer a Microsoft SQL Server 2012 database. The database is currently configured to log ship to a secondary server.
You are preparing to cut over to the secondary server by stopping log-shipping and bringing the secondary database online. You want to perform a tail-log backup.
You need to leave the primary database in a restoring state.
Which option of the BACKUP LOG command should you use?

You administer a Microsoft SQL Server 2012 database named Orders.
Orders contains a table named OrderShip that is defined as follows:

A NULL value represents a domestic order. Ninety percent of the values in CountryCode are NULL.
Customers require a procedure that will return orders for all customers from a specified country.
You create a new procedure:

Performance on this procedure is slow.
You need to alter the schema to optimize this query. Objects created must use a minimum amount of resources.
Which Transact-SQL statement should you use?

You administer a Microsoft SQL Server 2012 database instance.
You plan to migrate the database to Windows Azure SQL Database. You verify that all objects contained in the database are compatible with Windows Azure SQL
Database.
You need to ensure that database users and required server logins are migrated to Windows Azure SQL Database.

What should you do?

You administer a Windows Azure SQL Database database named Human_Resources. The database contains 2 tables named Employees and SalaryDetails. You
add two Windows groups as logins for the server:
CORP\\Employees – All company employees
CORP\\HRAdmins – HR administrators only
HR Administrators are also company employees.

You need to grant users access according to the following requirements:
CORP\\Employees should have SELECT access to the Employees table. Only users in CORP\\HRAdmins should have SELECT access to the SalaryDetails table.
Logins are based only on Windows security groups.
What should you do?

You administer a SQL Server 2012 database instance.
You need to configure the SQL Server Database Engine service on a failover cluster.
