You use Microsoft SQL Server 2012 to develop a database application. Your application sends data to an NVARCHAR(MAX) variable named @var. You need to write a Transact-SQL statement that will find out the success of a cast to a decimal (36,9). Which code segment should you use?select

• A. TRY( SELECT convert(decimal(36,9), @var) SELECT 'True' AS BadCast
  )
  CATCH(
  SELECT 'False' AS BadCast
  )
• B. BEGIN TRY
  SELECT convert(decimal(36,9), @var) AS Value, 'True' AS BadCast
  END TRY
  BEGIN CATCH
  SELECT convert(decimal(36,9), @var) AS Value, 'False' AS BadCast
  END CATCH
• C. SELECT
  IIF(TRY_PARSE(@var AS decimal(36,9)) IS NULL, 'True', 'False')
  AS BadCast
• D. SELECT
  CASE
  WHEN convert(decimal(36,9), @var) IS NULL
  THEN 'True'
  ELSE 'False'
  END
  AS BadCast

You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage area network (SAN). The financial database has the following characteristics:
A data file of 2 terabytes is located on a dedicated LUN (drive D).
A transaction log of 10 GB is located on a dedicated LUN (drive E).
Drive D has 1 terabyte of free disk space.
Drive E has 5 GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday between
09:00
hours and 17:00 hours. Five percent of the existing data is modified each day. The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the database. These data load operations must occur in the minimum amount of time. A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours. You need to ensure that your backup will continue if any invalid checksum is encountered. Which backup option should you use?

• A. CHECKSUM
• B. SIMPLE
• C. NO_CHECKSUM
• D. RESTART
• E. Transaction log
• F. Differential
• G. SKIP
• H. COPY_ONLY
• I. CONTINUE_AFTER_ERROR
• J. DBO_ONLY
• K. BULK_LOGGED
• L. NORECOVERY
• M. FULL
• N. STANDBY

You are developing a database application by using Microsoft SQL Server 2012. An application that uses a database begins to run slowly. Your investigation shows the root cause is a query against a read-only table that has a clustered index. The query returns the following six columns: * One column in its WHERE clause contained in a non-clustered index * Four additional columns * One COUNT (*) column based on a grouping of the four additional columns.
You need to optimize the statement. What should you do?

• A. Add a FORCESEEK hint to the query.
• B. Enable the optimize for ad hoc workloads option.
• C. Add a columnstore index to cover the query.
• D. Cover the unique clustered index with a columnstore index.
• E. Include a SET FORCEPLAN ON statement before you run the query.
• F. Include a SET STATISTICS PROFILE ON statement before you run the query.
• G. Include a SET TRANSACTION ISOLATION LEVEL SERIALIZABLE statement before you run the query.
• H. Add a FORCESCAN hint to the Attach query.
• I. Include a SET STATISTICS SHOWPLAN_XML ON statement before you run the query.
• J. Include a SET TRANSACTION ISOLATION LEVEL REPEATABLE READ statement before you run the query.
• K. Include a SET TRANSACTION ISOLATION LEVEL SNAPSHOT statement before you run the query.
• L. Add a LOOP hint to the query.
• M. Add a HASH hint to the query.
• N. Add an INCLUDE clause to the index.

You use a Microsoft SQL Server 2012 database. You need to create an indexed view within the database for a report that displays Customer Name and the total revenue for that customer. Which four T-SQL statements should you use? (To answer, move the appropriate SQL statements from the list of statements to the answer area and arrange them in the correct order.)
