Microsoft 70-523 Value Pack (Frequently Bought Together)

You are designing an ASP.NET Web application by using Microsoft Visual Studio 2010. The Web
application uses dynamic HTML (DHTML).
You need to ensure that the application functions properly on multiple browser platforms without requiring
the installation of a client-side component.
Which two approaches could you recommend? (Each correct answer presents a complete solution.
Choose two.)

• A. Use Microsoft Silverlight.
• B. Use jQuery.
• C. Use the ASP.NET Ajax Library.
• D. Use Microsoft Visual Basic Scripting Edition (VBScript).

You are developing an application to update a user's social status. You need to consume the service using
Windows Communication Foundation (WCF).
The client configuration is as follows.
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="SocialConfig">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Basic"
?realm="Social API" />
</security>
</binding>
</webHttpBinding>
</bindings>
<client>
<endpoint address="http://contoso.com"
binding="webHttpBinding"
bindingConfiguration="SocialConfig"
contract="ISocialStatus"
name="SocialClient" />
</client> </system.serviceModel> The service contract is defined as follows. [ServiceContract] public interface ISocialStatus {
[OperationContract]
[WebInvoke(UriTemplate =
"/statuses/update.xml?status={text}")]
void UpdateStatus(string text); } Which code segment should you use to update the social status?

• A. using (WebChannelFactory<ISocialStatus> factory = new WebChannelFactory<ISocialStatus>(typeof(ISocialClient))) { factory.Credentials.Windows.ClientCredential.UserName = user.Name; factory.Credentials.Windows.ClientCredential.SecurePassword. SetAt(0, Convert.ToChar(user.Password)); ISocialStatus socialChannel = factory.CreateChannel();
  socialChannel.UpdateStatus(newStatus);
  }
• B. using (WebChannelFactory<ISocialStatus> factory = new WebChannelFactory<ISocialStatus>("SocialClient"))
  {
  factory.Credentials.UserName.UserName = user.Name;
  factory.Credentials.UserName.Password = user.Password;
  ISocialStatus socialChannel = factory.CreateChannel();
  socialChannel.UpdateStatus(newStatus);
  }
• C. using (ChannelFactory<ISocialStatus> factory =
  new WebChannelFactory<ISocialStatus>(typeof(ISocialStatus)))
  {
  factory.Credentials.UserName.UserName = user.Name;
  factory.Credentials.UserName.Password = user.Password;
  ISocialStatus socialChannel = factory.CreateChannel();
  socialChannel.UpdateStatus(newStatus);
  }
• D. using (ChannelFactory<ISocialStatus> factory = new ChannelFactory<ISocialStatus>("POST")) { factory.Credentials.Windows.ClientCredential.UserName = user.Name; factory.Credentials.Windows.ClientCredential.SecurePassword. SetAt(0, Convert.ToChar(user.Password)); ISocialStatus socialChannel = factory.CreateChannel();
  socialChannel.UpdateStatus(newStatus);
  }

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

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. You use the ADO.NET Entity Data Model (EDM) to define a Customer entity. You need to add a new Customer to the data store without setting all the customer's properties. What should you do?

• A. Override the Create method for the Customer object.
• B. Call the CreateObject method of the Customer object.
• C. Call the Create method of the Customer object.
• D. Override the SaveChanges method for the Customer object.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to a Microsoft SQL Server 2008 database. The database includes a table that contains information about all the employees. The database table has a field named EmployeeType that identifies whether an employee is a Contractor or a Permanent employee. You declare the Employee entity base type. You create a new Association entity named Contractor that inherits the Employee base type. You need to ensure that all Contractors are bound to the Contractor class. What should you do?

• A. Modify the .edmx file to include the following line of code. <Condition ColumnName="EmployeeType" Value="Contractor" />
• B. Use the Entity Data Model Designer to set up an association between the Contractor class and EmployeeType.
• C. Modify the .edmx file to include the following line of code. <NavigationProperty Name="Type" FromRole="EmployeeType" ToRole="Contractor" />
• D. Use the Entity Data Model Designer to set up a referential constraint between the primary key of the Contractor class and EmployeeType.
