The Sales table contains a column named UnitsSold. UnitsSold contains the total number of units sold of each product. Each product appears in only one row. You have the following view: You discover that the view does not return a list of the top 100 selling products. You need to ensure that the view returns a list of the top 100 selling products. Which SQL statement should you use?  A.    Option AB.    Option BC.    Option CD.    Option D Answer: C QUESTION 122You are a database developer. You plan to design a database solution by using SQL Server 2008. A database contains a table named Customer. The structure of the Customer table is as shown in the following table. The solution uses the following stored procedure to return customer details. Users report that the stored procedure takes a long time to execute. You need to optimize the performance of the stored procedure. What should you do? A.    Recreate the primary key as a nonclustered unique index and build a clustered index on the country_id column.B.    Build a nonclustered index on the country_id column and use the INCLUDE clause to include the customer_name column.C.    Build a nonclustered index on the country_id, customer_name, and customer_id columns.D.    Build a nonclustered index only on the country_id column. Answer: B QUESTION 123You are a database developer. You plan to design a database solution by using SQL Server 2008. A frequently used query takes very long to execute. You discover that the query frequently uses full- table scans instead of indexes. This causes other queries that modify the table to be blocked. The indexing strategy on the underlying tables that the query uses can change. You need to design a solution that performs the following tasks:- Removes full-table scans- Allows the query optimizer to select the appropriate index.What should you do? A.    Use the INDEX table hint.B.    Use the INDEX(0) table hint.C.    Use the NOEXPAND table hint.D.    Use the FORCESEEK table hint. Answer: D QUESTION 124You are a database developer. You develop a database by using SQL Server 2008 in an enterprise environment. The database has a table named Sales.Inventory. The table is partitioned into four geographic regions. You update the Sales.Inventory table for each region by using the following stored procedure.CREATE STORED PROCEDURE usp_Update@RegionID tinyintASUPDATE Sales.InventorySET Qty = T.CurrentQuantityFROM Sales.Inventory IJOIN Sales.TempData T ON I.ItemID = T.ItemIDAND I.RegionID = @RegionID;The UPDATE statement locks the Sales.Inventory table when a single region is updated. You need to prevent the locking of the Sales.Inventory table when a single region is updated. What should you do? A.    Modify the usp_Update stored procedure to use the NOLOCK table hint for the UPDATE statement.B.    Modify the usp_Update stored procedure to use the SERIALIZABLE table hint for the UPDATE statement.C.    Run the following Transact-SQL statement.ALTER TABLE Sales.Inventory SET LOCK_ESCALATION = AUTOD.    Run the following Transact-SQL statement.ALTER TABLE Sales.Inventory SET LOCK_ESCALATION = TABLE Answer: C QUESTION 125You are a database developer. You plan to design a database solution by using SQL Server 2008. A stored procedure in a database uses a transaction to retrieve data from a table and produces aggregations.You must design a solution that meets the following requirements:- Update operations cannot be performed on the retrieved data while the stored procedure is being executed.- Insert operations in the table can be performed while the stored procedure is being executed.You need to ensure that the solution meets the requirements. What isolation level should you use? A.    SERIALIZABLEB.    READ COMMITTEDC.    REPEATABLE READD.    READ UNCOMMITTED Answer: C QUESTION 126You have a database that contains two tables. Both the XACT_ABORT database option and the IMPLICIT_TRANSACTIONS database option are set to OFF. You need to update both tables. If an update fails on either table, neither table should be updated. What should you do? A.    Use a transaction.B.    Change the isolation level.C.    Use the TABLOCK query hint.D.    Use the UPDLOCK query hint. Answer: A QUESTION 127You use SQL Server 2008 to design a database that will hold incoming XML responses for an EDI system. You have the following requirements:- The data is accessible to heterogeneous platforms:- The database stores various types of reports from multiple sources.- The solution allows search by keywords.- The database stores large amounts of data.- The database is scalable.You need to design the database to meet the given requirements. What should you do? A.    Use SQL Server 2008 tables to store data and include proper indexes.B.    Use ANSI text files to store text reports, and use SQL Server 2008 tables to store numerical reports.C.    Save reports in binary format in a file within a Windows folder. Save the path of the file in SQL Server 2008 tables.D.    Store reports in XML format, and use SQL Server 2008 tables to store the data. Index the XML data to improve performance. Answer: D QUESTION 128You are a database developer. You plan to design a database solution by using SQL Server 2008. The database contains a table that has two partitions. The first partition contains the current data, and the second partition contains historical data. There is a high frequency of data manipulation on the current data. The testers report that they are frequently unsuccessful in querying the historical data only. You discover that locks are being escalated to the table-level lock. You need to ensure that without modifying the SELECT statements, you enable users to query the historical data. You want to achieve this goal by using the minimum amount of administrative effort and minimally affecting other queries. What should you do? A.    Use the ALTER TABLE ... SET (LOCK_ESCALATION = AUTO) command.B.    Move the historical partition to a read-only filegroup.C.    Set the Server Startup Parameters to include -T1211.D.    Set DEADLOCK PRIORITY to HIGH. Answer: D QUESTION 129You are designing a new database. The tables of the database will be replicated to multiple offices. You need to design the tables to meet the following requirements:- A row identifier must be set when a row is created - The row identifier must be unique across the entire organization What should you recommend? A.    Add a column to all the tables that have the hierarchyid data type.B.    Add a column to all the tables that have a time data type. Configure the DEFAULT constraint to use the GETDATE () function.C.    Add a column to all the tables that have the identity property.D.    Add a column to all the tables that have a uniqueidentifier data type. Configure the DEFAULT constraint to use the NEWIDQ function. Answer: D QUESTION 130You need to design a table that will contain a monetary value. The value must support five digits to the right of the decimal point. Which data type should you choose? A.    decimalB.    bigintC.    intD.    money Answer: A Braindump2go New Released 70-451 Dump PDF Free Download, 147 Questions in all, Passing Your Exam 100% Easily! 70-451 PDF Dumps & 70-451 VCE Dumps Full Version Download(147q): http://www.braindump2go.com/70-451.html --------------------------------------------------- Images: --------------------------------------------------- --------------------------------------------------- Post date: 2015-08-20 07:09:45 Post date GMT: 2015-08-20 07:09:45 Post modified date: 2015-08-20 07:09:45 Post modified date GMT: 2015-08-20 07:09:45 ____________________________________________________________________________________________ Export of Post and Page as text file has been powered by [ Universal Post Manager ] plugin from www.gconverters.com
