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

1. You are testing an existing ASP.NET page. The page includes a text You are able to execute malicious JavaScript code by typing it in the text box and submitting. You need to configure the page to prevent JavaScript code from being submitted by the text box. In the @ Page directive, which attribute should you set to true?

A) the ResponseEncoding attribute
B) the EnableEventValidation attribute
C) the ValidateRequest attribute
D) the Strict attribute

2. You are designing a data access service backed by Microsoft SQL Server. Other developers will use your
service as a third-party service.
You have the following requirements:
*To reduce maintenance cost, you must write the minimal amount of code required for fulfilling the goals.
*The service must function with Microsoft and non-Microsoft technologies.
*The service must implement the WS-Security standards.
You need to design the service to meet the requirements.
Which approach should you recommend?

A) Use an .ashx file to return an XML response over HTTPS.
B) Use SQL Server XML Web services.
C) Use a WCF service with multiple bindings.
D) Use an ASP.NET Web service.

3. Your Windows Communication Foundation (WCF) client application uses HTTP to communicate with the
service. You need to enable message logging and include all security information such as tokens and
nonces in logged messages.
What should you do?

A) In the machine configuration file, add the following XML segment to the system.serviceModel configuration section. <machineSettings enableLoggingKnownPii="true" /> Generate the ContosoService class using the Add Service Reference wizard. Add the following code segment. Dim client As ContosoService = New ContosoService() client.Endpoint.Behaviors.Add(New CallbackDebugBehavior(True))
B) In the application configuration file, add the logKnownPii attribute to the message logging diagnostics source and set the value of the attribute to true. Generate the ContosoService class using the Add Service Reference wizard. Add a reference to System.ServiceModel.Routing.dll. Add the following code segment. Dim client As ContosoService = New ContosoService() Dim behavior As SoapProcessingBehavior = New SoapProcessingBehavior() behavior.ProcessMessages = True client.Endpoint.Behaviors.Add(behavior)
C) In the application configuration file, add the following XML segment to the system.serviceModel configuration section group. <diagnostics>
<messageLogging logMessagesAtTransportLevel="true"
logEntireMessage="true" />
</diagnostics>
D) In the machine configuration file, add the following XML segment to the system.serviceModel configuration section. <machineSettings enableLoggingKnownPii="true" /> In the application configuration file, add the logKnownPii attribute to the message logging diagnostics source and set the value of the attribute to true. In the application configuration file, add the following XML segment to the system.serviceModel configuration section group. <diagnostics>
<messageLogging logMessagesAtTransportLevel="true"/>
</diagnostics>

4. You are creating a Windows Communication Foundation (WCF) service that implements operations in a
RESTful manner.
You need to add a delete operation.
You implement the delete method as follows.
string void DeleteItems(string id);
You need to configure WCF to call this method when the client calls the service with the HTTP DELETE
operation. What should you do?

A) Add the WebInvoke(UriTemplate = "/Items/{id}",Method="DELETE") attribute to the operation.
B) Add the HttpDelete attribute to the operation.
C) Replace the return type with RemovedActivityAction.
D) Replace the string parameter with a RemovedActivityAction parameter.

5. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application.
The application contains the following code segment. (Line numbers are included for reference only.)
01 class DataAccessLayer
02 {
03 private static string connString;
04
05 ...
06 public static DataTable GetDataTable(string command){
07
08 ...
09 }
10 }
You need to define the connection life cycle of the DataAccessLayer class. You also need to ensure that
the application uses the minimum number of connections to the database.
What should you do?

A) Insert the following code segment at line 04. private static SqlConnection conn = new SqlConnection(connString); public static void Open(){
conn.Open();
}
public static void Close(){
conn.Close();
}
B) Insert the following code segment at line 07. using (SqlConnection conn = new SqlConnection(connString)){
conn.Open();
}
C) Replace line 01 with the following code segment.
class DataAccessLayer : IDisposable
Insert the following code segment to line 04.
private SqlConnection conn = new SqlConnection(connString);
public void Open(){
conn.Open();
}
public void Dispose(){
conn.Close();
}
D) Insert the following code segment at line 04. private SqlConnection conn = new SqlConnection(connString); public void Open(){
conn.Open();
}
public void Close(){
conn.Close();
}
