Four Windows Communication Foundation (WCF) services are hosted in Microsoft Internet Information
Services (IIS). No behavior configuration exists in the web.config file.
You need to configure the application so that every service and endpoint limits the number of concurrent
calls to 50 and the number of concurrent sessions to 25.
Which XML segment should you add to the system.serviceModel configuration section of the web.config
file?

• A.<behaviors> <serviceBehaviors> <behavior name="ALL"> <serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="25"/> </behavior>
  </serviceBehaviors>
  </behaviors>
• B.<behaviors> <serviceBehaviors> <behavior name="*"> <serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="25"/> </behavior>
  </serviceBehaviors>
  </behaviors>
• C.<behaviors> <serviceBehaviors> <behavior name=""> <serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="25"/> </behavior>
  </serviceBehaviors>
  </behaviors>
• D.<behaviors> <serviceBehaviors> <behavior name="default"> <serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="25"/> </behavior>
  </serviceBehaviors>
  </behaviors>

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application uses the ADO.NET Entity Framework to model entities. The application allows users to make
changes to entities while disconnected from the central data store.
You need to ensure that when the user connects to the central data store and retrieves new data, the
application meets the following requirements:
*Changes made to the local data store in disconnected mode are preserved.
*Entities that have already been loaded into the local data store, but have not been modified by the user,
are updated with the latest data.
What should you do?

• A.Call the query's Execute method by using the MergeOptions.AppendOnly option.
• B.Call the query's Execute method by using the MergeOptions.OverwriteChanges option.
• C.Call the Refresh method of ObjectContext by using the RefreshMode.StoreWins option.
• D.Call the Refresh method of ObjectContext by using the RefreshMode.ClientWins method.

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
records contain a null value in the LineTotal field and 0 in the Quantity field. You write the following code
segment. (Line numbers are included for reference only.)
01DataColumn column = new DataColumn("UnitPrice", typeof(double));
02
03OrderDetailTable.Columns.Add(column);
You need to add a calculated DataColumn named UnitPrice to the OrderDetailTable object. You also need
to ensure that UnitPrice is set to 0 when it cannot be calculated. Which code segment should you insert at
line 02?

• A.column.Expression = "if(Quantity > 0, LineTotal/Quantity, 0)";
• B.column.Expression = "LineTotal/ISNULL(Quantity, 1)";
• C.column.Expression = "LineTotal/Quantity";
• D.column.Expression = "iif(Quantity > 0, LineTotal/Quantity, 0)";

A Windows Communication Foundation (WCF) service has the following contract.
[ServiceContract(Namespace="http://contoso.com")]
public interface IShipping
{ [OperationContract] string DoWork(int id);
}
This is one of several service contracts hosted by your application. All endpoints use SOAP 1.2 bindings
with WS-Addressing 1.0. The System.ServiceModel.MessageLogging trace source in the system.
diagnostics configuration section is configured with one listener.
You need to make sure that only the messages that are returned from the DoWork operation are logged.
Which XML segment should you add to the system.serviceModel/diagnostics/messageLogging/filters
configuration element?

• A.<add xmlns:addr="http://www.w3.org/2005/08/addressing"> //addr:Action[text() = 'http://contoso.com/IShipping/DoWorkResponse'] </add>
• B.<add xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> //soap:Action[text() = 'http://contoso.com/IShipping/DoWorkResponse'] </add>
• C.<add xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> //soap:Action[text() = 'http://contoso.com/IShipping/DoWork'] </add>
• D.<add xmlns:addr="http://www.w3.org/2005/08/addressing"> //addr:Action[text() = 'http://contoso.com/IShipping/DoWork'] </add>

You are designing the user interface for an ASP.NET Web application. The Web application allows several departments to personalize the style of their sections of the Web application.
All departmental section styles derive from the core styles of the Web application and can only append to
the Web application's core styles. The departmental master pages inherit from the Web application's
master page.
You need to ensure that core CSS styles appear in all pages of the Web application.
Which approach should you recommend?

• A.Link from the Web application's master page to a css.ascx file containing the CSS styles.
• B.Add a master.css file containing the CSS styles to the Web application.
• C.Link from the Web application's master page to a .css file containing the CSS styles.
• D.Add a ContentPlaceHolder containing the CSS styles to the Web application's master page.
