1. BACKGROUND company overview Tailspin toys is a regional toy store chain,with stores in 30
cities. Planned Changes The company wants to add an online store to its chain of retail stores.A prototype of the online store was developed by using SQL server 2000 .However,the IT manager wants to move to SQL Sever 2005 to take advantage of its new features. The IT manager plans to automate certain database maintenance operations,including scripting of database objects,backup and restore activities ,and creation and maintenance of endpoints. Problem Statement The nightly processing of the sales data from each store executes very slowly.with the addition of the online store,this performance must be improved in order to complete the processing within the allotted frame. EXISTING ENVIRONMENT Existing Application Environment The prototype of the online store is experiencing poor concurrency. Existing supporting Infrastructure Currently,the point of sale(POS) system for the retail stores has a SQL Server 2000 database.Tailspin Toys has an Enterprise Resource planning(ERP) system running on UNIX that must be able to communicate with the online store's Inventory database. BUSINESS REQUIREMENTS General Application Solution Requirements The company is developing an online store that is capable of displaying pictures,prices,and information on products that are sold
by Tailspin Toys. Customers must be able to find out whether toys that are available online are also available at a physical store for pickup.The store inventory for a selected store must be queried realtime as the individual toys are displayed.Inventory quantities for a toy must all be displayed prior to processing the next toy. Store managers often run reports that query for all sales for a given date range. New toys are introduced at the online store only once per month. Performance When a customer uses the online store to perform a search for toys,it should return results in 15 seconds or less. Users can search for a toy category. The results of this search should be used for future searches by the same user,to minimize round trips to the database. TECHNICAL REQUIREMENTS Resource usage on the database server must be minimized. The online store will have two databases named Sales and Inventory.When a sale is completed,both databases must be kept consistent with each other. The IT department has specified that the online store will use a serviceoriented architecture for data access.

2. You need to design the data access strategy for the Tailspin Toys online store search requirement. Which strategy should you use?
A. System.Xml.XmlReader
B. System.Data.SqlClient.SqlDataReader
C. System.Data.DataSet
D. CLR userdefined type
Answer: C

3. You are troubleshooting concurrency problems with the code that was originally developed on the SQL Server 2000 database. You discover that there are excessive read locks on important tables. You need to resolve the problem. What should you do?

D. Set the READ_COMMITTED_SNAPSHOT database option to ON.
Answer: D

4. You need to design the user interface that will display availability to pick up items at a retail store for items that are ordered online. You also must minimize the number of connections to the database. Which data access strategy should you use?
A. ActiveX data objects (ADO)
B. multiple active result sets (MARS)
C. System.Data.DataReader
D. System.Data.DataSet
Answer: B

5. You design the following stored procedure that will be used by sales managers. CREATE PROCEDURE StoreSales (@StartDate datetime, @EndDate datetime) AS SET TRANSACTION ISOLATION LEVEL SERIALIZABLE SELECT StoreID, TotalSales FROM Sales WHERE SaleDate BETWEEN @StartDate AND @EndDate While tuning the query, you notice that table locks are occurring. You need to resolve the problem. What should you do?
A. Change the isolation level to READ COMMITTED.
B. Add a HOLDLOCK table hint to the query.
C. Add a NOWAIT table hint to the query.
D. Add a READPAST table hint to the query.
Answer: A

6. You are designing the stored procedure that updates inventory quantities. The stored procedure contains the following code. CREATE PROCEDURE UpdateInventory (@ProductID int, @Amount int) AS BEGIN TRANSACTION DECLARE @CurrentQuantity int SELECT @CurrentQuantity = Quantity FROM Inventory.ProductInventory WHERE ProductID = @ProductID UPDATE Inventory.ProductInventory SET Product.Quantity = @CurrentQuantity + @Amount WHERE ProductID = @ProductID IF @@ERROR <> 0 ROLLBACK TRAN ELSE COMMIT TRAN You discover that the ProductInventory column is occasionally updated incorrectly. You need to resolve the problem. What should you do?
A. Add a SET TRANSACTION ISOLATION LEVEL SERIALIZABLE statement to the stored procedure.
B. Remove the SELECT statement from the stored procedure. Perform the update using the Product.Quantity column instead of the @CurrentQuantity variable.
C. Add a NOLOCK hint to the SELECT statement.
D. Move the BEGIN TRANSACTION statement so that it immediately precedes the UPDATE statement.
Answer: B

7. You are designing a stored procedure that records a sale and decreases the inventory for the items that are being purchased. The stored procedure contains the following code. CREATE PROCEDURE UpdateSalesAndInventory (@ProductID int, @quantity int) AS SET IMPLICIT_TRANSACTION ON INSERT INTO Sales.SalesOrder Values(@ProductID, @quantity) UPDATE Inventory.ProductInventory SET Quantity = Quantity @quantity WHERE ProductID =
@ProductID You run this stored procedure and discover that no updates are applied. You need to resolve the problem. What should you do?
A. Change SET IMPLICIT_TRANSACTION to OFF.
B. Use multiple active result sets (MARS) to execute the stored procedure.
C. Add logic to commit or roll back the transaction based on the successful updates of the data.
D. Add a BEGIN TRANSACTION statement to the stored procedure.
Answer: C

8. BACKGROUND Company Overview Margie's Travel is a small regional travel agency that handles many different types of travel arrangements. Planned Change Margie's Travel has purchased a COM component named Cruisex to be used to access cruise lines information. Margie's Travel hosts the component in COM+.Cruisex will be used for two purposes:to retrieve a readonly list of available cruises,and to make reservations on cruises.Cruisex uses all default settings. Problem Statements Many of the company's inhouse travel agents that the Web site that
is used for making travel reservations is too difficult to use. The company wants to create a smart client application that will deliver a richer client experience for the agents. The solution must support the Web site application for offsite travel agents. A monthly agentcommission report has been created. This report will be executed once per month.This report currently uses a cursor with the INSENSITIVE argument.The test team reports that this report runs slowly and consumes a significant amount of database server resources. A stored procedure named UpdateSeatSelection
is used to update seat selections for airline reservations. The test team reports that there is significant blocking when this stored procedure is being executed. EXISTING ENVIRONMENT Existing Supporing Infrastructure The current travel agent application stores its data in a SQL Server 2005 database. BUSINESS REQUIREMENTS General Application Solution Requirements The duplication of application logic must be minimized. After an airline reservation is made,the aqent must help the customer with seat selection. The seat selection process should not block the application from performing other reservation tasks.However,the agent must have the ability to cancel a seat selection query prior to its completion.The application must receive a reply that cancellatio was successful. A report named FlightsBooked is being developed.The test team reports that executing the report twice within a single transaction using the same parameters occasionally produces different results. However,subsequnt executions with those same parameters produce consistent results. A feature must be developed that will allow travel agents
to seach for customers by name of partial name.The data that is returned must not include any data that is not yet committed. Performance To improve performance for the data access layer,the number of round trips to the database must be limited,particularly for data that changes only infrequently. Infrequent changes are made to the information about trading partners such as airlines,cruise lines,and hotel chains.Margie's Travel wants to limit the bandwidth that is required
to ensure that the smart client application has the current values for trading partners .The company wants to mininize the development effort that is needed to support this requirement. When an agent queries for available fight information,the data must be returned as quickly as possible.This data will not be modified by the agent. A monthly agentcommission report has been created.This report will be executed once per month.This report currently uses a cursor with the INSENSITIVE argument.The test team reports that this report runs slowly and consumes a significant amount of database server reslurces. Recoverability Once per month,all sales data must be transferred to the Accounting database,which is on the same database server instance.In the case of failure,recovery of the travel agent database and the Accounting database must be ensured to the same logical point in time. TECHNICAL REQUIREMENTS Security External access to company data must be allowed for only a specified set of IP addresses.

9. You need to improve the performance and reduce the database resource usage of the stored procedure that will be used to generate the monthly agentcommission report. What should you do?
A. Remove the INSENSITIVE argument from the cursor declaration.
B. Add the OPTIMISTIC argument to the cursor declaration.
C. Rewrite the stored procedure using set operations.
D. Rewrite the stored procedure as a userdefined type.
Answer: C

10. You need to design the data access object model to be used for the infrequently changing data about trading partners. What should you use?
A.ActiveX data objects (ADO) B.System.Data.DataReader C.System.Data.DataSet D.System.Xml.XmlReader Answer: C
11.You need to design the data access method for accessing the SQL Server 2005 computer. You must ensure that your solution supports the Web site and the smart client application. Which data access technology should you use?
A. SqlXmlCommand
B. updategrams
C. XML template queries
D. HTTP endpoints
Answer: D
