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

1. You are implementing an ASP.NET application that makes extensive use of JavaScript libraries. Not all pages use all scripts, and some scripts depend on other scripts. When these libraries load sequentially, some of your pages load too slowly. You need to use the ASP.NET Ajax Library Script Loader to load these scripts in parallel. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) In each page that uses scripts, add a call to Sys.require for each script that is needed in that page.
B) In your site's master page, add a call to Sys.loader.registerScript to define each of the scripts that are used in the site.
C) In each page that uses scripts, add a call to Sys.get for each script that is needed in that page.
D) In your site's master page, add a call to Sys.loader.defineScripts to define each of the scripts that are used in the site.

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application updates several Microsoft SQL Server databases within a single transaction. You need to ensure that after a resource failure, you can manage unresolved transactions. What should you do?

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

3. You use Microsoft Visual Studio 2010 and Microsoft ADO.NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. You use the ADO.NET LINQ to SQL model to retrieve data from the database. You use stored procedures to return multiple result sets. You need to ensure that the result sets are returned as strongly typed values. What should you do?

A) Apply the ParameterAttribute to the stored procedure function. Use the GetResult <TElement> method to obtain an enumerator of the correct type.
B) Apply the FunctionAttribute and ResultTypeAttribute to the stored procedure function. Use the GetResult <TElement> method to obtain an enumerator of the correct type.
C) Apply the ResultTypeAttribute to the stored procedure function and directly access the strongly typed object from the results collection.
D) Apply the FunctionAttribute and ParameterAttribute to the stored procedure function and directly access the strongly typed object from the results collection.

4. 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 database includes a database table named ProductCatalog as shown in the exhibit. (Click the Exhibit
button.)
You add the following code segment to query the first row of the ProductCatalog table. (Line numbers are
included for reference only.)
01 using (var cnx = new SqlConnection(connString))
02 {
03 var command = cnx.CreateCommand();
04 command.CommandType = CommandType.Text;
05 command.CommandText ="SELECT TOP 1 * FROM dbo.ProductCatalog";
06 cnx.Open();
07 var reader = command.ExecuteReader();
08 if (reader.Read()) {
09 var id = reader.GetInt32(0);
10
11 reader.Close();
12 }
13 }
You need to read the values for the Weight, Price, and Status columns.
Which code segment should you insert at line 10?
Exhibit:

A) var weight = reader.GetDouble(1); var price = reader.GetFloat(2); var status = reader.GetBoolean(3);
B) var weight = reader.GetFloat(1); var price = reader.GetDouble(2); var status = reader.GetByte(3);
C) var weight = reader.GetDecimal(1); var price = reader.GetFloat(2); var status = reader.GetByte(3);
D) var weight = reader.GetDouble(1); var price = reader.GetDecimal(2); var status = reader.GetBoolean(3);

5. You are implementing an ASP.NET AJAX page. You add two UpdatePanel controls named pnlA and pnlB.
pnlA contains an UpdatePanel control named pnlAInner in its content template.
You have the following requirements.
?Update panels pnlA and pnlB must refresh their content only when controls that they contain cause a
postback.
?Update panel pnlAInner must refresh its content when controls in either pnlA or pnlB or pnlAInner cause a
postback.
You need to configure the panels to meet the requirements.
What should you do?

A) Set the UpdateMode of pnlA and pnlB to Conditional. Set the UpdateMode of pnlAInner to Conditional, and add AsyncPostBackTrigger elements to its Triggers element for every control in pnlA.
B) Set the UpdateMode of pnlA and pnlB to Always. Set the UpdateMode of pnlAInner to Always, and add AsyncPostBackTrigger elements to its Triggers element for every control in pnlB.
C) Set the UpdateMode of pnlA and pnlB to Conditional. Set the UpdateMode of pnlAInner to Always.
D) Set the UpdateMode of pnlA and pnlB to Always. Set the UpdateMode of pnlAInner to Conditional.
