Braindumps of 70-305

Developing and Implementing Web Apps with MS VB.NET

Exam Questions, Answers, Braindumps (70-305)

Thanks to www.exams.ws and www.examcheats.net. But there’s no need to have it from both of them, only questions from only one are sufficient I think.

1:- You create an ASP.NET application that is deployed on your company’s intranet. Sales representatives use this application to connect to a database while they are speaking to customers on the telephone. Your code is running under the security context of the user who requested the page. The application requires each sales representative to supply a unique user name and password to access the application. These individual user names and passwords are included in the ConnectionString property settings that your code uses to connect to the database. All users have the same access rights to the database. Sales representatives report that it takes a long time to access the database. You test the application and discover that a new connection is created each time a sales representative connects to the database. You want to reuse connections in order to reduce the time it takes to access the database. What should you do?

A. Modify the connection string to specify Windows Integrated authentication.

B. Modify the connection string to increase the connection timeout setting.

C. Modify the connection string so that is uses a single application user name and password for every connection to the database.

D. Modify the connection string so that is uses a login user named that is a member of the sysadmin fixed server role.

Answer: C

2:- You are creating an ASP.NET application to track FolksTec sales orders. The application uses an ADO.NET DataSet object that contains two DataTable objects. One table is named Orders, and the other table is named OrderDetails. The application displays data from the Orders table in a list box. You want the order details for an order to be displayed in a grid when a user selects the order in the list box. You want to modify these objects to enable your code to find all the order details for the selected order. What should you do?

A. Add a DataRelation object to the Relations collection of the DataSet object.

B. Use the DataSet.Merge method to connect the Orders table and the OrderDetails table to each other.

C. Add a ForeignKeyConstraint to the OrderDetails table.

D. Add a keyref constraint to the DataSet schema.

Answer: A

3:- You create an ASP.NET application for online ordering. You need to store a small amount of page-specific information on pages that are submitted to the server. This information does not need to be secured. The page must work properly for browsers that do not support cookies. You anticipate that the volume of orders on the site will be high, and you need to conserve server resources. What should you do?

A. Store the information in application state variables.

B. Store the information in session state variables.

C. Store the information in a Microsoft SQL Server database.

D. Store the information in hidden fields on the page.

Answer: D

4:- You develop a Windows-based application that accesses a Microsoft SQL Server database. Users must supply a user name and password when they start the application. This information is then used to dynamically build a connection string. When you test the application, you discover that it is not using the SqlClient connection pooling feature. You must reduce the time needed to retrieve information. How should you modify the connection string?

A. To use the Windows user logon when connecting to the database.

B. To use the SQL Server user login when connection to the database.

C. To use the same application logon ID and password for every connection to the database.

D. To use the guest login ID and password for every connection to the database.

Answer: C

5:- You are creating a new ASP.NET page named ItemList that displays item and price information for many different items. When a user logs on to the Web site, the page retrieves the current list of prices from a database. ItemList will be accessed by several thousand registered users. When a price list is retrieved for a user, the prices remain valid for as long as the user continues to access the page. Users are allowed to keep the same price list for several days. When ItemList is posted back to the server, you want to ensure that the price list was not altered on the user’s computer. You also want to minimize the memory resources consumed on the Web server. Which three parameters should you add to the Page directive in ItemList? (Each correct answer presents part of the solution. Choose three)

A. EnableSessionState=”True”

B. EnableSessionState=”False”

C. EnableSessionState=”ReadOnly”

D. EnableViewState=”True”

E. EnableViewState=”False”

F. EnableViewStateMac=”True”

G. EnableViewStateMac=”False”

Answer: C, D, F

6:- You develop a Windows-based application that accesses a Microsoft SQL Server database. Users must supply a user name and password when they start the application. This information is then used to dynamically build a connection string. When you test the application, you discover that it is not using the SqlClient connection pooling feature. You must reduce the time needed to retrieve information. How should you modify the connection string?

A. To use the Windows user logon when connecting to the database.

B. To use the SQL Server user login when connection to the database.

C. To use the same application logon ID and password for every connection to the database.

D. To use the guest login ID and password for every connection to the database.
