Question 3
You develop an application. You are using the ServiceModel Metadata Utility Tool (svcutil.exe) to generate
service bindings.
The service bindings must use stringent security and require full control over the Windows Communication
Foundation (WCF) messaging stack.
You need to configure the service bindings.
Which values should you use? To answer, configure the appropriate options in the dialog box in the answer
area.
NOTE: Each correct selection is worth one point.

Correct Answer:
Explanation
Box 1: WSHttpBinding
A secure and interoperable binding that is suitable for non-duplex service contracts.
Incorrect: Always select a binding that includes security. By default, all bindings except the
<basicHttpBinding> element have security enabled.
Box 2: Sign
Sign. The protected part is digitally signed. This ensures detection of any tampering with the protected
message part.
Box 3: <wsHttpBing>

Question 4
Historical flight information data will be stored in Windows Azure Table Storage using the FlightInfo class as
the table entity.
There are millions of entries in the table. Queries for historical flight information specify a set of airlines to
search and whether the query should return only late flights. Results should be ordered by flight name.
You need to specify which properties of the FlightInfo class should be used at the partition and row keys to
ensure that query results are returned as quickly as possible.
What should you do? (To answer, drag the appropriate properties to the correct location or locations in the
answer area. Each property may be used once, more than once, or not at all. You may need to drag the split bar
between panes or scroll to view content.)

Question 5
You are developing an ASP.NET MVC application that displays a report. The report includes large images
that are stored in a database. Members of the EntityClient namespace are used to access the database through
the ADO.NET Entity Framework data model.
You need to prevent memory exceptions while generating a report using the EntityDataRcader type.
Which CommandBehavior type should you use?

Correct Answer: B
Question 7
You are developing a Windows Communication Foundation (WCF) service named WCF1.
WCF1 will use a certificate to secure the communication channel.
You need to ensure that the WCF service uses a certificate to secure the communication channel.
How should you complete the code? To answer, drag the appropriate code blocks to the correct locations. Each
code block may be used once, more than once, or not at all. You may need to drag the split bar between panes
or scroll to view content.

Correct Answer:
Explanation
Target 1: ClientCredentialType
Target 2: MessageCredentialType.Certificate
Set the ClientCredential property to an appropriate value. The following code sets the property to Certificate.
WSHttpBinding b = new WSHttpBinding();
b.Security.Mode = SecurityMode.Message;
b.Security.Message.ClientCredentialType = MessageCredentialType.Certificate;
Target 3: SetCertificate
On the client class, set the ClientCredentials property of the ClientBase<TChannel> class to an appropriate
value.
Example: // Set the certificate for the client.
cc.ClientCredentials.ClientCertificate.SetCertificate(
StoreLocation.LocalMachine,
StoreName.My,
X509FindType.FindBySubjectName,
"cohowinery.com");
