  public class Address

  {

  public int AddressType;

  public string Line1;

• Question 243:

  You are implementing an ASP.NET application that makes extensive use of JavaScript libraries. Not all pages use all scripts, and some scripts depend on other scripts. When these libraries load sequentially, some of your pages load too slowly. You need to use the ASP.NET Ajax Library Script Loader to load these scripts in parallel.

  A. In your site's master page, add a call to Sys.loader.defineScripts to define each of the scripts that are used in the site.
  B. In your site's master page, add a call to Sys.loader.registerScript to define each of the scripts that are used in the site.
  C. In each page that uses scripts, add a call to Sys.get for each script that is needed in that page.
  D. In each page that uses scripts, add a call to Sys.require for each script that is needed in that page.
  A. In your site's master page, add a call to Sys.loader.defineScripts to define each of the scripts that are used in the site.
  D. In each page that uses scripts, add a call to Sys.require for each script that is needed in that page.

• Question 245:

  You are developing an ASP.NET Web page.

  You add a data-bound GridView control. The GridView contains a TemplateField that includes a DropDownList. You set the GridViews ClientIDMode property to Static, and you set the ClientIDRowSuffix property to ProductID.

  What should you set the ClientIDMode property of the DropDownList to?

  A. AutoID
  B. Static
  C. Inherit

• Question 246:

  You are implementing an ASP.NET application that uses LINQ to Entities to access and update the database.

  The application includes the following method to update a detached entity of type Person.

  private NorthwindContext _entities;

  public void UpdatePerson(Person personToEdit)

  {

  }

  You need to implement the UpdatePerson method to update the database row that corresponds to the personToEdit object.

  Which code segment should you use?

  A. _entities.People.Attach(personToEdit);_entities.ObjectStateManager.ChangeObjectState (personToEdit, EntityState.Modified);_entities.SaveChanges();
  B. _entities.ObjectStateManager.ChangeObjectState (personToEdit,EntityState.Added);_entities.SaveChan ges();
  C. _entities.People.ApplyCurrentValues(personToEdit);_entities.SaveChanges();
  D. _entities.People.Attach(new Person() { Id = personToEdit.Id }); _entities.ObjectStateManager.ChangeObjectState(personToEdit,EntityState.Modified);_entities.SaveC hanges();
  A. _entities.People.Attach(personToEdit);_entities.ObjectStateManager.ChangeObjectState (personToEdit, EntityState.Modified);_entities.SaveChanges();

• Question 247:

  You are dynamically adding controls to an ASP.NET page in the Page_Load event handler. The page will have text boxes that correspond to the columns in a database table. Each text box will be preceded by a label that displays the name of

  the corresponding column.

  You need to create the form so that when the user clicks the label, the corresponding text box is selected for input.

  What should you do?

  A. For each column, output the following HTML, where COL is replaced by the name of the column.COL
  B. For each column, output the following HTML, where COL is replaced by the name of the column.COL
  C. For each column, create an asp:Label control and a corresponding asp:TextBox that have the same ID.
  D. For each column, create an asp:Label control and set the AssociatedControlID to the ID of thecorresponding asp:Textbox control.
  D. For each column, create an asp:Label control and set the AssociatedControlID to the ID of thecorresponding asp:Textbox control.

• Question 248:

  You are developing a Web page. The user types a credit card number into an input control named cc and clicks a button named submit. The submit button sends the credit card number to the server. A JavaScript library includes a

  CheckCreditCard function that returns a value of true if the credit card appears to be valid, based on its checksum.

  You need to ensure that the form cannot be used to submit invalid credit card numbers to the server.

  What should you do?

  A. Configure the input control to run on the server. On the submit button, add a server-side OnClick handler that calls CheckCreditCard and rejects the form submission if the input is invalid.
  B. On the input control, add an onChange handler that calls CheckCreditCard and cancels the form submission when the input is invalid.
  C. Configure the input control and the submit button to run on the server. Add a submit_OnClick handler that calls CheckCreditCard and rejects the form submission if the input is invalid.
  D. On the form, add an onSubmit handler that calls CheckCreditCard and cancels the form submission if the input is invalid.
  D. On the form, add an onSubmit handler that calls CheckCreditCard and cancels the form submission if the input is invalid.

  C. _entities.People.ApplyCurrentValues(personToEdit); _entities.SaveChanges(); _entities.People.Attach (new Person() { Id = personToEdit.Id });
  D. _entities.ObjectStateManager.ChangeObjectState( personToEdit, EntityState.Modified); _entities.SaveChanges();
  A. _entities.People.Attach(personToEdit); _entities.ObjectStateManager.ChangeObjectState( personToEdit, EntityState.Modified); _entities.SaveChanges();

• Question 250:

  You are implementing an ASP.NET application that includes the following requirements. Retrieve the number of active bugs from the cache, if the number is present. If the number is not found in the cache, call a method named GetActiveBugs, and save the result under the ActiveBugs cache key. Ensure that cached data expires after 30 seconds. You need to add code to fulfill the requirements.

  Which code segment should you add?

  A. Dim numOfActiveBugs As Integer? = DirectCast(Cache("ActiveBugs"), Integer?) If Not numOfActiveBugs.HasValue Then Dim result As Int32 = GetActiveBugs() Cache.Insert("ActiveBugs", result, Nothing, DateTime.Now.AddSeconds(30), Cache.NoSlidingExpiration) numOfActiveBugs = result End If ActiveBugs = numOfActiveBugs.Value
  B. Dim numOfActiveBugs As Integer = CInt(Cache.Get("ActiveBugs")) If numOfActiveBugs 0 Then Dim result As Integer = GetActiveBugs() Cache.Insert("ActiveBugs", result, Nothing, DateTime.Now.AddSeconds(30), Cache.NoSlidingExpiration) numOfActiveBugs = result End If ActiveBugs = numOfActiveBugs
  C. Dim numOfActiveBugs As Integer = 0 If Cache("ActiveBugs") Is Nothing Then Dim result As Integer = GetActiveBugs() Cache.Add("ActiveBugs", result, Nothing, DateTime.Now.AddSeconds(30), Cache.NoSlidingExpiration, CacheItemPriority.Normal, Nothing) numOfActiveBugs = result End If ActiveBugs = numOfActiveBugs
  D. Dim numOfActiveBugs? As Integer = DirectCast(Cache("ActiveBugs"), Integer?) If Not numOfActiveBugs.HasValue Then Dim result As Integer = GetActiveBugs() Cache.Insert("ActiveBugs", result, Nothing, Cache.NoAbsoluteExpiration, TimeSpan.FromSeconds(30)) numOfActiveBugs = result End If ActiveBugs = numOfActiveBugs.Value
  A. Dim numOfActiveBugs As Integer? = DirectCast(Cache("ActiveBugs"), Integer?) If Not numOfActiveBugs.HasValue Then Dim result As Int32 = GetActiveBugs() Cache.Insert("ActiveBugs", result, Nothing, DateTime.Now.AddSeconds(30), Cache.NoSlidingExpiration) numOfActiveBugs = result End If ActiveBugs = numOfActiveBugs.Value
