Which code segment should you insert at line 04?
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 the following object query to load a product from the database. (Line numbers are included for reference only.)
01using (AdventureWorksEntities advWorksContext = new AdventureWorksEntities())
02{
03ObjectQuery <Product> productQuery = advWorksContext.Product.Where(“it.ProductID = 900”);
04
05}
You need to log the command that the query executes against the data source. Which code segment should you insert at line 04?
Which XML segment should you add to the system.serviceModel configuration section of the web.config file?
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?
Which code segment should you use?
A performance issue exists in the application. The following code segment is causing a performance bottleneck:
var colors = context.Parts.GetColors();
You need to improve application performance by reducing the number of database calls. Which code segment should you use?
Which code segment should you use?
You are creating an ASP.NET Web site. You create a HTTP module named CustomModule, and you register the module in the web.config file.
The CustomModule class contains the following code.
public class CustomModule : IHttpModule
{
string footerContent = “<div>Footer Content</div>”;
public void Dispose() {}
}
You need to add code to CustomModule to append the footer content to each processed ASP.NET page.
Which code segment should you use?
What should you do?
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?
Which two actions should you perform?
You are adding a Windows Communication Foundation (WCF) service to an existing application. The application is configured as follows. (Line numbers are included for reference only.)
01 <configuration>
02 <system.serviceModel>
03 <services>
04 <service name=”Contoso.Sales.StockService”
05 behaviorConfiguration=”MetadataBehavior”>
06 <host>
07 <baseAddresses>
08 <add baseAddress=”http://contoso.com:8080/StockService” />
09 </baseAddresses>
10 </host>
11 </service>
12 </services>
13 <behaviors>
14 <serviceBehaviors>
15 <behavior name=”MetadataBehavior”>
16 </behavior>
17 </serviceBehaviors>
18 </behaviors>
You need to configure the service to publish the service metadata. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
What should you do?
The Entity Data Model file (.edmx file) must be updated to support inheritance mapping for Products and Componets.
You need to add the following code to the \Model\Model.edmx file:
* the code in line EX243 that maps the Product type
* the code in line EX250 that maps the Component type
What should you do?
Which code segment should you use?
You are creating an ASP.NET Web site.
The site is configured to use Membership and Role management providers.
You need to check whether the currently logged-on user is a member of a role named Administrators.
Which code segment should you use?
Which cryptography provider should you use?
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 stores encrypted credit card numbers in the database. You need to ensure that credit card numbers can be extracted from the database. Which cryptography provider should you use?
Which message encoding should you use?
A Windows Communication Foundation (WCF) service is responsible for transmitting XML documents between systems. The service has the following requirements: It must minimize the transmission size by attaching the XML document as is without using escape characters or base64 encoding. It must interoperate with systems that use SOAP but are not built on the .NET platform. You need to configure the service to support these requirements. Which message encoding should you use?
