Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 1 Sample Questions:

You need to create an inline table-valued function named Sales.fn_OrdersByTerritory, which must meet the following requirements:
Accept the @T integer parameter.
Use one-part names to reference columns.
Filter the query results by SalesTerritoryID.
Return the columns in the same order as the order used in OrdersByTerritoryView.
Which code segment should you use?
To answer, type the correct code in the answer area.

A) CREATE FUNCTION Sales.fn_OrdersByTerritory (@T int) RETURNS TABLE AS RETURN ( SELECT OrderID,OrderDate,SalesTerrirotyID,TotalDue FROM Sales.OrdersByTerritory WHERE SalesTerritoryID = @T )

2. You generate a daily report according to the following query:

You need to improve the performance of the query. What should you do?

A) Rewrite the report query as follows:
SELECT c.CustomerName
FROM Sales.Customer c
WHERE NOT EXISTS (SELECT OrderDate FROM Sales.ufnGetRecentOrders(c.
CustomerID, 90))
Rewrite the UDF as follows:
CREATE FUNCTION Sales.ufnGetRecentOrders(@CustomerID int, @MaxAge datetime)
RETURNS TABLE AS RETURN (
SELECT OrderDate
FROM Sales.SalesOrder
WHERE s.CustomerID = @CustomerID
AND s.OrderDate > DATEADD(DAY, -@MaxAge, GETDATE())
B) Drop the UDF and rewrite the report query as follows:
WITH cte(CustomerID, LastOrderDate) AS ( SELECT CustomerID, MAX(OrderDate) AS [LastOrderDate] FROM Sales.SalesOrder GROUP BY CustomerID
)
SELECT c.CustomerName
FROM cte
INNER JOIN Sales.Customer c
ON cte.CustomerID = c.CustomerID
WHERE cte.LastOrderDate < DATEADD(DAY, -90, GETDATE())
C) Drop the UDF and rewrite the report query as follows:
SELECT c.CustomerName
FROM Sales.Customer c
WHERE NOT EXISTS (
SELECT s.OrderDate
FROM Sales.SalesOrder
WHERE s.OrderDate > DATEADD(DAY, -90, GETDATE())
AND s.CustomerID = c.CustomerID)
D) Drop the UDF and rewrite the report query as follows:
SELECT DISTINCT c.CustomerName
FROM Sales.Customer c
INNER JOIN Sales.SalesOrder s
ON c.CustomerID = s.CustomerID
WHERE s.OrderDate < DATEADD(DAY, -90, GETDATE())

3. You administer a Microsoft SQL Server 2012 server that hosts a transactional database and a reporting database.

the reporting database is restored. You also need to ensure that data loss is minimal.
What should you do?

A) Restore the latest full backup.
B) 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.
C) Restore the latest full backup. Then, restore the latest differential backup.
D) Restore the latest full backup, and restore the latest differential backup. Then, restore the latest log backup.
E) Perform a point-in-time restore.
