A.    An auditB.    A dynamic management viewC.    A maintenance planD.    A SQL Server Agent alert Answer: BExplanation:Dynamic Management Views and Functions (Transact-SQL) QUESTION 82You need to recommend a solution to improve the performance of usp.UpdateInventory. The solution must minimize the amount of development effort.What should you include in the recommendation? A.    A table variableB.    A common table expressionC.    A subqueryD.    A cursor Answer: AExplanation:*Scenario: Database2 will contain a stored procedure named usp_UpdateInventory. Usp_UpdateInventory will manipulate a table that contains a self-join that has an unlimited number of hierarchies.* A table variable can be very useful to store temporary data and return the data in the table format.table* Example: The following example uses a self-join to find the products that are supplied by more than one vendor.Because this query involves a join of the ProductVendor table with itself, the ProductVendor table appears in two roles. To distinguish these roles, you must give the ProductVendor table two different aliases (pv1 and pv2) in the FROM clause. These aliases are used to qualify the column names in the rest of the query. This is an example of the self-join Transact-SQL statement:USE AdventureWorks2008R2;GOSELECT DISTINCT pv1.ProductID, pv1.VendorIDFROM Purchasing.ProductVendor pv1INNER JOIN Purchasing.ProductVendor pv2ON pv1.ProductID = pv2.ProductIDAND pv1.VendorID <> pv2.VendorIDORDER BY pv1.ProductIDIncorrect:Not B: Using a CTE offers the advantages of improved readability and ease in maintenance of complex queries. The query can be divided into separate, simple, logical building blocks. These simple blocks can then be used to build more complex, interim CTEs until the final result set is generated. QUESTION 83You need to recommend a solution for the deployment of SQL Server 2014. The solution must meet the business requirements.What should you include in the recommendation? A.    Create a new instance of SQL Server 2014 on the server that hosts the SQL Server 2008 instance.B.    Upgrade the existing SQL Server 2008 instance to SQL Server 2014.C.    Deploy two servers that have SQL Server 2014 installed and implement Failover Clustering.D.    Deploy two servers that have SQL Server 2014 installed and implement database mirroring. Answer: CExplanation:Scenario: The databases must be available if the SQL Server service fails.Failover Clustering OverviewWindows Server Failover Clustering (WSFC) with SQL Server QUESTION 84You need to recommend a solution to synchronize Database2 to App1_Db1.What should you recommend? A.    Change data captureB.    Snapshot replicationC.    Master Data ServicesD.    Transactional replication Answer: DExplanation:Scenario:* Data from Database2 will be accessed periodically by an external application named Application1. The data from Database2 will be sent to a database named App1_Db1 as soon as changes occur to the data in Database2.* All data in Database2 is recreated each day and does not change until the next data creation process. QUESTION 85You need to recommend a database reporting solution that meets the business requirements.What should you include in the recommendation? A.    Data collectionB.    Performance MonitorC.    A maintenance planD.    A dynamic management view Answer: AExplanation:* Scenario: System administrators must be able to run real-time reports on disk usage.* The data collector provides an historical report for each of the System Data collection sets. Each of the following reports use data that is stored in the management data warehouse:Disk Usage SummaryQuery Statistics HistoryServer Activity HistoryYou can use these reports to obtain information for monitoring system capacity and troubleshooting system performance.System Data Collection Set Reports QUESTION 86You need to recommend an isolation level for usp_UpdateOrderDetails.Which isolation level should recommend? A.    Read committedB.    Repeatable readC.    Read uncommittedD.    Serializable Answer: BExplanation:* Scenario: Databasel will also contain a stored procedure named usp_UpdateOrderDetails. The stored procedure is used to update order information. The stored procedure queries the Orders table twice each time the procedure executes. The rows returned from the first query must be returned on the second query unchanged along with any rows added to the table between the two read operations.* REPEATABLE READSpecifies that statements cannot read data that has been modified but not yet committed by other transactions and that no other transactions can modify data that has been read by the current transaction until the current transaction completes.Transaction Isolation Levels Case Study 8 - Contoso Ltd (Question 87 - Question 96)OverviewApplication OverviewContoso, Ltd., is the developer of an enterprise resource planning (ERP) application. Contoso is designing a new version of the ERP application. The previous version of the ERP application used SQL Server 2008 R2. The new version will use SQL Server 2014. The ERP application relies on an import process to load supplier data. The import process updates thousands of rows simultaneously, requires exclusive access to the database, and runs daily.You receive several support calls reporting unexpected behavior in the ERP application. After analyzing the calls, you conclude that users made changes directly to the tables in the database.TablesThe current database schema contains a table named OrderDetails. The OrderDetails table contains information about the items sold for each purchase order. OrderDetails stores the product ID, quantities, and discounts applied to each product in a purchase order. The product price is stored in a table named Products.The Products table was defined by using the SQL_Latin1_General_CPl_CI_AS collation. A column named ProductName was created by using the varchar data type.The database contains a table named Orders. Orders contains all of the purchase orders from the last 12 months. Purchase orders that are older than 12 months are stored in a table named OrdersOld.Stored ProceduresThe current version of the database contains stored procedures that change two tables. The following shows the relevant portions of the two stored procedures: Customer ProblemsInstallation IssuesThe current version of the ERP application requires that several SQL Server logins be set up to function correctly. Most customers set up the ERP application in multiple locations and must create logins multiple times.Index Fragmentation IssuesCustomers discover that clustered indexes often are fragmented. To resolve this issue, the customers defragment the indexes more frequently.All of the tables affected by fragmentation have the following columns that are used as the clustered index key: Backup IssuesCustomers who have large amounts of historical purchase order data report that backup time is unacceptable.Search IssuesUsers report that when they search product names, the search results exclude product names that contain accents, unless the search string includes the accent.Missing Data IssuesCustomers report that when they make a price change in the Products table, they cannot retrieve the price that the item was sold for in previous orders.Query Performance IssuesCustomers report that query performance degrades very quickly. Additionally, the customers report that users cannot run queries when SQL Server runs maintenance tasks.Import IssuesDuring the monthly import process, database administrators receive many supports call from users who report that they cannot access the supplier data. The database administrators want to reduce the amount of time required to import the data.Design RequirementsFile Storage RequirementsThe ERP database stores scanned documents that are larger than 2 MB. These files must only be accessed through the ERP application. File access must have the best possible read and write performance.Data Recovery RequirementsIf the import process fails, the database must be returned to its prior state immediately.Security RequirementsYou must provide users with the ability to execute functions within the ERP application, without having direct access to the underlying tables.Concurrency RequirementsYou must reduce the likelihood of deadlocks occurring when Sales.Proc1 and Sales.Proc2 execute. QUESTION 87You need to recommend a solution that resolves the missing data issue. The solution must minimize the amount of development effort.What should you recommend? A.    Denormalize the Products table.B.    Denormalize the OrderDetails table.C.    Normalize the OrderDetails table.D.    Normalize the Products table. Answer: DExplanation:* Scenario:/ Missing Data IssuesCustomers report that when they make a price change in the Products table, they cannot retrieve the price that the item was sold for in previous orders. / The current database schema contains a table named OrderDetails. The OrderDetails table contains information about the items sold for each purchase order. OrderDetails stores the product ID, quantities, and discounts applied to each product in a purchase order. The product price is stored in a table named Products. http://technet.microsoft.com/en-us/library/aa933055(v=sql.80).aspx QUESTION 88You need to recommend a solution that addresses the index fragmentation and index width issue.What should you include in the recommendation? (Each correct answer presents part of the solution. Choose all that apply.) A.    Change the data type of the lastModified column to smalldatetime.B.    Remove the lastModified column from the clustered index.C.    Change the data type of the modifiedBy column to tinyint.D.    Change the data type of the id column to bigint.E.    Remove the modifiedBy column from the clustered index.F.    Remove the id column from the clustered index. Answer: BEExplanation:Scenario: Index Fragmentation Issues Customers discover that clustered indexes often are fragmented. To resolve this issue, the customers defragment the indexes more frequently.All of the tables affected by fragmentation have the following columns that are used as the clustered index key:  QUESTION 89You need to recommend a solution that reduces the time it takes to import the supplier data.What should you include in the recommendation? A.    Enable instant file initialization.B.    Reorganize the indexes.C.    Disable Resource Governor.D.    Enable Auto Update Statistics. Answer: CExplanation:* The ERP application relies on an import process to load supplier data. The import process updates thousands of rows simultaneously, requires exclusive access to the database, and runs daily. QUESTION 90You need to recommend a solution that meets the data recovery requirement.What should you include in the recommendation? A.    A differential backupB.    A transaction log backupC.    Snapshot isolationD.    A database snapshot Answer: D Braindump2go New Updated 70-469 Exam Dumps are Complete Microsoft 70-469 Course Coverage! 100% Real Questions and Correct Answers Guaranteed!
