• Question 2:

  You work as an ASP.NET Web Application Developer for SomeCompany. The company uses Visual Studio .NET 2010 as its application development platform. You create an ASP.NET Web application using .NET Framework 4.0.

  The Web application connects to a SQL Server database. You use the ADO.NET Entity Framework to handle persistence-ignorant entities.

• Question 4:

  You create a Visual Studio 2010 solution that includes a WCF service project and an ASP.NET project. The service includes a method named GetPeople that takes no arguments and returns an array of Person objects. The ASP.NET application uses a proxy class to access the service. You use the Add Service Reference wizard to generate the class. After you create the proxy, you move the service endpoint to a different port. You need to configure the client to use the new service address. In addition, you must change the implementation so that calls to the client proxy will return a List instead of an array. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

  A. In the context menu for the service reference in the ASP.NET project, select the Configure Service Reference command, and set the collection type to System.Collections.Generic.List.
  B. In the context menu for the service reference in the ASP.NET project, select the Update Service Reference command to retrieve the new service configuration.
  C. Change the service interface and implementation to return a List.
  D. Edit the address property of the endpoint element in the web.config file to use the new service address.
  A. In the context menu for the service reference in the ASP.NET project, select the Configure Service Reference command, and set the collection type to System.Collections.Generic.List.
  D. Edit the address property of the endpoint element in the web.config file to use the new service address.

• Question 5:

  You are developing an ASP.Net MVC 2 view and controller. The controller includes an action method that retrieves rows from a Product table in Microsoft SQL Server database. You need to cache the data that the action method returns. What should you do?

  A. Add the following section to the web.config file.
  B. Add the following line of code to the controller.Cache.insert("key", "ProductView", null, DateTime.Now.AddMinutes(60),TimeSpan.Zero);
  C. Add the following attribute to the action method[OutputCache(Duration=60)];
  D. Add the following directive to the top of the view
  C. Add the following attribute to the action method[OutputCache(Duration=60)];

• Question 6:

  You are implementing an ASP.NET page that includes the following down list.

  You need to dynamically add values to the end of the drop-down list.

  What should you do?

  A. Add the following OnPreRender event handler to the asp:DropDownListPrivate Sub mydropdown_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles mydropdown.PreRenderDim ddl As DropDownList = TryCast (sender, DropDownList)Dim lbl As Label = New Label()lbl.Text = "Option"lbl.ID = "Option"ddl.Controls.Add(lbl)End Sub
  B. Add the following OnPreRender event handler to the asp:DropDownListPrivate Sub mydropdown_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles mydropdown.PreRender Dim ddl As DropDownList = TryCast (sender, DropDownList)ddl.Items.Add("Option")End Sub
  C. Add the following event handler to the page code-behind.Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)Handles Me.LoadDim ddl As DropDownList = TryCast(Page.FindControl ("mydropdown"),DropDownList)Dim lbl As Label = New Label()lbl.Text = "Option"lbl.ID = "Option"ddl.Controls.Add(lbl)End Sub
  D. Add the following event handler to the page code-behind.Private Sub Page_LoadComplete(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.LoadCompleteTryCast(Page.FindControl("mydropdown"), DropDownList)ddl.Items.Add("Option")End Sub
  B. Add the following OnPreRender event handler to the asp:DropDownListPrivate Sub mydropdown_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles mydropdown.PreRender Dim ddl As DropDownList = TryCast (sender, DropDownList)ddl.Items.Add("Option")End Sub

• Question 7:

  You are developing an ASP.NET web application.

  The application includes the following Entity Data Model (EDM):

  

  You instantiate an ObjectContext for the EDM named context. You need to find the total number of addresses that are associated with customers that have a non-null middle name. Which LINQ to Entities query should you use?

  A. var query = context.Customers.Where(c => c.MiddleName != null).Select(c =>
  B. CustomerAddresses.Count();
  C. var query = context.Customers.Where(c => c.MiddleName != null).SelectMany(c =>
  D. CustomerAddresses.Count();
  E. var query = context.Addresses.SelectMany(a =>
  F. CustomerAddresses.OfType().Where(c => c.MiddleName != null)).Count();
  G. var query = context.Addresses.GroupBy(a => a.CustomerAddresses.Where(ca => ca.Customer.MiddleName != null)).Count();
  B. CustomerAddresses.Count();

• Question 8:

  You are implementing an ASP.NET page. Client-side script requires datA.

  Your application includes a class named Person with a Name property of type string.

  The code-behind file of the page includes the following code segment.

  public string JsonValue;

  List people = GetPeopleList();

  JavaScriptSerializer json = new JavaScriptSerializer();

  You need to use the JavaScriptSerializer class to serialize only the Name property of each item in the people list.

  B. var names = from person in peopleselect person; JsonValue = "{" + json.Serialize(names) + "}";
  C. JsonValue = json.Serialize(people.SelectMany( p => p.Name.AsEnumerable()));
  D. var names = from person in peopleselect person; JsonValue = json.Serialize(names);
  A. JsonValue = json.Serialize(people.Select(p => p.Name));

• Question 9:

  You are implementing a new Dynamic Data Web site.

  The Web site includes a Web page that has an ObjectDataSource control named ObjectDataSource1. ObjectDataSource1 interacts with a Web service that exposes methods for listing and editing instances of a cla named Product.

  You add a GridView control named GridView1 to the page, and you specify that GridView1 should use ObjectDataSource1 as its data source.

  You then configure GridView1 to auto-generate fields and to enable editing. You need to add Dynamic Data behavior to GridView1. You also must ensure that users can use GridView1 to update Product instances.

  Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

  B. Disable the auto-generated fields on GridView1. Add a DynamicField control for each field of the Product class.
  C. Add the following code segment to the Application_Start method in the Global.asax.cs file.DefaultModel.RegisterContext(typeof(System.Web.UI.WebControls.ObjectDataSource),new ContextConfiguration() {ScaffoldAllTables = true});
  D. Add the following code segment to the Page_Init method of the Web page.GridView1.EnableDynamicData(typeof(Product));
  B. Disable the auto-generated fields on GridView1. Add a DynamicField control for each field of the Product class.
  D. Add the following code segment to the Page_Init method of the Web page.GridView1.EnableDynamicData(typeof(Product));
