You use Entity SQL of the ADO.NE Entity Framework to retrieve data from the database. You need to define a custom function in the conceptual model. You also need to ensure that the function calculates a value based on properties of the object. Which two XML element types should you use? (Each correct answer presents part of the solution. Choose two.)

A) Association
B) Function
C) Dependent

public string SecretHandshake { get; set; }
}
You have the following requirements:
"The CodeName property must be sent in clear text.
The service must be able to verify that the property value was not changed after being sent by the client.
"The SecretHandshake property must not be sent in clear text and must be readable by the service. What should you do?

A) Add a DataProtectionPermission attribute to the each property and set the ProtectData property to true.
B) Add an XmlText attribute to the CodeName property and set the DataType property to Signed. Add a PasswordPropertyText attribute to the SecretHandshake property and set its value to true.
C) Add a MessageBodyMember attribute to the CodeName property and set the ProtectionLevel to Sign. Add a MessageBodyMember attribute to the SecretHandshake property and set the ProtectionLevel to EncryptAndSign.
D) Add an ImmutableObject attribute to the CodeName property and set its value property to true. Add a Browsable attribute to the SecretHandshake property and set its value to false.

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application connects to a Microsoft SQL Server database.

You add the following code segment to the application. (Line numbers are included for reference only.)
01 public void QueryPlayers(List <League> leagues) {
02
03 }
You create a LINQ query to retrieve a collection of Player objects.
You need to ensure that the collection includes all the players from each team and every league.
Which code segment should you insert at line 02?

B) var query = leagues.SelectMany(l => l.Teams.Select(t => t.Players));
C) var query = leagues.Select(l => l.Teams.Select(t => t.Players));
D) var query = leagues.Select(l => l.Teams.SelectMany(t => t.Players));

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application connects to a Microsoft SQL Server database. The application uses a DataTable named
OrderDetailTable that has the following columns: "ID "OrderID "ProductID "Quantity "LineTotal Some
