Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 1 : 070-457

You administer all the deployments of Microsoft SQL Server 2012 in your company. You need to ensure that an OLTP database that uses a storage area network (SAN) remains available if any of the servers fail. You also need to minimize the amount of storage used by the database. Which configuration should you use?

• A. * Two servers configured in the same data center * SQL Server Availability Group configured in Asynchronous-Commit Availability Mode * One server configured as an Active Secondary
• B. * Two servers configured in a Windows Failover Cluster in the same data center * SQL Server configured as a clustered instance
• C. * Two servers configured in different data centers * SQL Server Availability Group configured in Asynchronous-Commit Availability Mode
• D. * SQL Server that includes an application database configured to perform snapshot replication
• E. * Two servers configured on the same subnet * SQL Server Availability Group configured in Synchronous-Commit Availability Mode
• F. * SQL Server that includes an application database configured to perform transactional replication
• G. * Two servers configured in different data centers * SQL Server Availability Group configured in Synchronous-Commit Availability Mode * One server configured as an Active Secondary
• H. * Two servers configured in the same data center * A primary server configured to perform log-shipping every 10 minutes * A backup server configured as a warm standby

You are a database developer for an application hosted on a Microsoft SQL Server 2012 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?

• A. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer c INNER JOIN
  (SELECT CustomerID, ShippingCountry,
  RANK() OVER (PARTITION BY CustomerID
  ORDER BY OrderAmount DESC) AS Rnk
  FROM Orders
  GROUP BY CustomerID, ShippingCountry) AS o
  ON c.CustomerID = o.CustomerID
  WHERE o.Rnk = 1
• B. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer c INNER JOIN
  (SELECT CustomerID, ShippingCountry,
  RANK() OVER (PARTITION BY CustomerID
  ORDER BY COUNT(OrderAmount) DESC) AS Rnk
  FROM Orders
  GROUP BY CustomerID, ShippingCountry) AS o
  ON c.CustomerID = o.CustomerID
  WHERE o.Rnk = 1
• C. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM (SELECT c.CustomerID, c.CustomerName, o.ShippingCountry, RANK() OVER (PARTITION BY CustomerID
  ORDER BY COUNT(o.OrderAmount) ASC) AS Rnk
  FROM Customer c
  INNER JOIN Orders o
  ON c.CustomerID = o.CustomerID
  GROUP BY c.CustomerID, c.CustomerName, o.ShippingCountry) cs
  WHERE Rnk = 1
• D. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer c INNER JOIN
  (SELECT CustomerID, ShippingCountry,
  COUNT(OrderAmount) DESC) AS OrderAmount
  FROM Orders
  GROUP BY CustomerID, ShippingCountry) AS o
  ON c.CustomerID = o.CustomerID
  ORDER BY OrderAmount DESC

You administer a Microsoft SQL Server 2012 instance that has several SQL Server Agent jobs configured.
When SQL Server Agent jobs fail, the error messages returned by the job steps do not provide the required
detail. The following error message is an example error message:
"The job failed. The Job was invoked by User CONTOSO\ServiceAccount. The last step to run was step 1
(Subplan_1)."
You need to ensure that all available details of the job step failures for SQL Server Agent jobs are retained.
What should you do?

• A. Configure event forwarding.
• B. Expand agent logging to include information from all events.
• C. Configure output files.
• D. Disable the Limit size of job history log feature.

You administer a Microsoft SQL Server 2012 server that hosts a transactional database and a reporting database. The transactional database is updated through a web application and is operational throughout the day. The reporting database is only updated from the transactional database. The recovery model and backup schedule are configured as shown in the following table:

The differential backup of the reporting database fails. Then, the reporting database fails at 14:00 hours.
You need to ensure that the reporting database is restored. You also need to ensure that data loss is minimal. What should you do?

• A. Perform a partial restore.
• B. Perform a point-in-time restore.
• C. Restore the latest full backup. Then, restore each differential backup taken before the time of failure from the most recent full backup.
• D. Perform a page restore.
• E. Restore the latest full backup.
• F. Restore the latest full backup, and restore the latest differential backup. Then, restore each log backup taken before the time of failure from the most recent differential backup.
• G. Restore the latest full backup. Then, restore the latest differential backup.
• H. Restore the latest full backup, and restore the latest differential backup. Then, restore the latest log backup.

You have an XML schema collection named Sales.InvoiceSchema. You need to declare a variable of the
XML type named XML1. The solution must ensure that XML1 is validated by using Sales.InvoiceSchema.
Which code segment should you use?
To answer, type the correct code in the answer area.

• A. Declare @XML1=XML(Sales.InvoiceSchema)
• B. DECLARE @XML1 XML @XML1 = Sales.InvoiceSchema CREATE XML SCHEMA COLLECTION XML1 AS @XML1
