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

You need to configure a single service endpoint with the following logical and physical addresses:
Which configuration setting should you use?

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

2. You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application exposes a Windows Communication Foundation (WCF) service that will be consumed by an ASP. NET application. The WCF application and the ASP.NET application will be deployed on the same server. You need to ensure that the WCF service meets the following requirements:
The communication between the applications incurs minimum latency. The binding satisfies the ordered delivery constraint that is specified in the service implementation by using the DeliveryRequirements attribute.
Which binding object should you use?

A) NetNamedPipeBinding
B) WSHttpBinding
C) NetTcpBinding
D) NetPeerTcpBinding

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 <ServiceContractO> _
03 Public Class MyService 04...
05 End Class
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) <ServiceBehaviorO"ransactionTimeout:="0:150:00")>_
B) <ServiceBehavior(TransactionTimeout:="2:30:00")> _
C) <ServiceBehavior(TransactionTimeout:="0:2:30")> _
D) <ServiceBehavior(TransactionTimeout:="150")> _

You need to ensure that the client application trusts and validates the certificate.
What should you do?

A) Subscribe to the ServerCertificateValidationCallback event of the System.Net.ServicePointManager class.
Write the validation code in the boolValidate(object sender, X509Certificate cert, X509Chain chain. System.Net.Security.SslPolicyErrors error) event handler on the client side.
B) Derive a class from the System.IdentityModel.Selectors.X509CertificateValidator class.
Create an instance of the derived class on the server side.
Write the validation code in the public override void Validate(X509Certificate2 certificate) method.
C) Subscribe to the ServerCertificateValidationCallback event of the System.Net.ServicePointManager class.
Write the validation code in the boolValidate(object sender, X509Certificate cert, X509Chain chain. System.Net.Security .SslPolicyErrors error) event handler on the server side.
D) Derive a class from the System.IdentityModel.Selectors.X509CertificateValidator class.
Create an instance of the derived class on the client side.
