Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation Sample Questions:

1. You are creating a Windows Communication Foundation client application by using Microsoft .NET Framework 3.5.
The client application consumes the Web Services Enhancements (WSE) 3.0 Web service.
The Web service uses standard WSE 3.0 to transfer binary data to the client application.
The client application uses the following binding configuration.
(Line numbers are included for reference only.)

You need to ensure that the client application receives binary data from the WSE 3.0 Web service.
Which code fragment should you insert at line 03?

A) Option A
B) Option B
C) Option D
D) Option C

2. You are creating a client application by using Microsoft .NET Framework 3.5. The
application consumes an ASMX Web service.
You need to configure the binding to call the methods of the ASMX Web service.
Which binding should you use?

A) Option A
B) Option B
C) Option D
D) Option C

3. You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment for the service contract. (Line numbers are included for reference only.)
01 [ServiceContract]
03 public class MyService
04 { 05...
06 }
The service uses transactions that time out in a minute. You need to increase the timeout interval of the transactions to 2 minutes and 30 seconds. Which code segment should you insert at line 02?

A) [ServiceBehavior(TransactionTimeout="2:30:00")]
B) [ServiceBehavior(TransactionTimeout="150")]
C) [ServiceBehaviorO"ransactionTimeout="0:150:00")]
D) [ServiceBehavior(TransactionTimeout="0:2:30")]

4. You are creating a distributed application by using Microsoft .NET Framework 3.5.
The application uses the Windows Communication Foundation model.
You need to ensure that the following requirements are met:
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A) Option A
B) Option B
C) Option D
D) Option C

5. You create a distributed application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation to create the application.
You pass the client credentials to the service that runs on two Web servers named IIS1 and IIS2. The service uses the credentials to query data from a remote Microsoft SQL Server 2005 database named DB1.
The client applications can retrieve data from the service when they connect to IIS1. When the client applications attempt to retrieve data from the service by connecting to IIS2, they receive the following error message:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
You need to ensure that both IIS1 and IIS2 can query data from DB1.
What should you do?

A) Configure DB1 for full delegation.
B) Execute the following command on a domain controller. setspn -A http/iis2.example.com:80 DOMAIN\iis2$
C) Change the SQL connection string on IIS2 from "Data Source=DBl; Initial Catalog=db;Integrated Security=True" to "Data Source=DBl;Initial Catalog=db;Integrated Security=SSPI".
D) Configure IIS2 for constrained delegation to DB1.
