Microsoft UPG:Transition MCPD.NET Frmwrk 3.5 Web Dev to 4 Web Dev Sample Questions:

1. You are designing the user interface for an ASP.NET Web application. The Web application allows several departments to personalize the style of their sections of the Web application.
All departmental section styles derive from the core styles of the Web application and can only append to
the Web application's core styles. The departmental master pages inherit from the Web application's
master page.
You need to ensure that core CSS styles appear in all pages of the Web application.
Which approach should you recommend?

A) Add a master.css file containing the CSS styles to the Web application.
B) Link from the Web application's master page to a css.ascx file containing the CSS styles.
C) Add a ContentPlaceHolder containing the CSS styles to the Web application's master page.
D) Link from the Web application's master page to a .css file containing the CSS styles.

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to several SQL Server databases. You create a function that modifies customer records that are stored in multiple databases. All updates for a given record are performed in a single transaction. You need to ensure that all transactions can be recovered. What should you do?

A) Call the EnlistDurable method of the Transaction class.
B) Call the Reenlist method of the TransactionManager class.
C) Call the EnlistVolatile method of the Transaction class.
D) Call the RecoveryComplete method of the TransactionManager class.

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application connects to a Microsoft SQL Server database. You write the following code segment that
executes two commands against the database within a transaction. (Line numbers are included for
reference only.)
01using (SqlConnection connection = new SqlConnection(cnnStr)) {
02connection.Open();
03SqlTransaction sqlTran = connection.BeginTransaction();
04SqlCommand command = connection.CreateCommand();
05command.Transaction = sqlTran;
06try {
07command.CommandText = "INSERT INTO Production.ScrapReason(Name) VALUES('Wrong size')";
08command.ExecuteNonQuery();
09command.CommandText = "INSERT INTO Production.ScrapReason(Name) VALUES('Wrong color')";
10command.ExecuteNonQuery();
11
12}
You need to log error information if the transaction fails to commit or roll back.
Which code segment should you insert at line 11?

A) catch (Exception ex) { sqlTran.Rollback(); Trace.WriteLine(ex.Message); } finaly { try { sqltran.commit( ); } catch (Exception exRollback) { Trace.WriteLine(excommit.Message); }}
B) catch (Exception ex){ Trace.WriteLine(ex.Message); try{ sqlTran.Rollback(); } catch (Exception exRollback){ Trace.WriteLine(exRollback.Message); }} finaly { sqltran.commit( );}}
C) sqlTran.Commit(); } catch (Exception ex) { sqlTran.Rollback(); Trace.WriteLine(ex.Message); }
D) sqlTran.Commit(); } catch (Exception ex) { Trace.WriteLine(ex.Message); try {
sqlTran.Rollback();
}
catch (Exception exRollback) {
Trace.WriteLine(exRollback.Message);
} } }

4. You create a page in an ASP.NET Web application. The page retrieves and displays data from a Microsoft SQL Server database. You need to create a data source that can connect to the database. What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A) Use a SqlDataSource control and configure its ConnectionString in the web.config file.
B) Use an ObjectDataSource control and set its TypeName property to System.Data.SqlClient. SqlConnection.
C) Use a LinqDataSource control with entity classes that represent the elements in the database.
D) Use an XmlDataSource control together with an Xml control that represents the database.

5. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. The application uses DataContexts to query the database. You create a function that meets the following requirements: *Updates the Customer table on the database when a customer is marked as deleted. *Updates the related entries in other tables (CustomerAddress, CustomerContacts) by marking them as deleted. *Prevents consumer code from setting the Deleted column's value directly. You need to ensure that the function verifies that customers have no outstanding orders before they are marked as deleted. You also need to ensure that existing applications can use the updated function without requiring changes in the code. What should you do?

A) Override the Delete operation of the DataContext object.
B) Override the Update operation of the DataContext object.
C) Add new entities to the DataContext object for the Customers and Orders tables.
