Microsoft TS: Ms Virtual Earth 6.0, Application Development : 070-544

You are integrating third-party data into a Virtual Earth 6.0 application. The data that is retrieved from the third party is stored in an array named Results. The Results array is stored inside a Web handler. The data is stored in the following format.
Results(0).Add("name", "Mike Pizzaria") Results(0).Add("address", "123 Main St., New
York, NY") Results(0).Add("latitude", "40.123") Results(0).Add("longitude", "-70.456")
Results(0).Add("thumbnail", "http://www.site.com/st3465.jpg") ... Return Results The Web handler uses the GeoRSSFeed class to accept items of type GeoRSSItem. The class contains the ToString() method that writes the GeoRSS feed to a string. The Web handler
GeoRSS integration is defined by the following code segment. (Line numbers are included for reference only.) 01 Dim feed As New GeoRSSFeed() 02 Dim curItem As GeoRSSItem
03 For i As Integer = 0 To Results.Count - 1 04 curItem = New GeoRSSItem() 05 ... 06 feed.Add(curItem) 07 Next 08 // Write feed to HTTP Response 09
context.Write(feed.ToString()); The Web handler uses the GeoRSSItem class that contains the following code segment. (Line numbers are included for reference only.) 10
Public Class GeoRSSItem 11 Public elements As Dictionary(Of String, String) 12 Public
Sub New() 13 elements = New Dictionary(Of String, String)() 14 End Sub 15 Public Sub
Add(ByVal pName As String, _ ByVal pValue As String) 16 elements.Add(pName, pValue)
17 End Sub 18 Public Overloads Overrides Function ToString() As String 19 Dim returnValue As New StringBuilder() 20 For Each key As String In elements.Keys 21 returnValue.AppendFormat("" & Chr(9) & "" & _ Chr(9) & "<{0}>{1}</{0}>" & Chr(10) & "", _ key, elements(key)) 22 Next 23 Return returnValue.ToString() 24 End Function 25 End
Class You need to encode the data inside the Results array into the GeoRSS format.
Which code segment should you insert at line 05?

• A. Dim objEnumerator As IEnumerator Dim Keys As Collections.Generic.Dictionary(Of
  String, _ String).KeyCollection = Results(i).Keys() Dim curKey As String objEnumerator =
  Keys.GetEnumerator() Do While objEnumerator.MoveNext curKey =
  objEnumerator.Current curItem.Add(curKey, Results(i)(curKey)) Loop
• B. curItem.Add("title", Results(i)("name")) curItem.Add("description", Results(i)("address")) curItem.Add("latitude", Results(i)("latitude")) curItem.Add("longitude",
  Results(i)("longitude")) curItem.Add("icon", Results(i)("thumbnail"))
• C. curItem.Add("name", Results(i)("name")) curItem.Add("address", string.Format("{0}|{1}",
  _ Results(i)("address"), Results(i)("thumbnail")) curItem.Add("latitude",
  Results(i)("latitude")) curItem.Add("longitude", Results(i)("longitude"))
• D. curItem.Add("title", Results(i)("name")) curItem.Add("description",
  String.Format("{0}|{1}", _ Results(i)("address"), Results(i)("thumbnail"))) curItem.Add("latitude", Results(i)("latitude")) curItem.Add("longitude",
  Results(i)("longitude"))

You are creating a Web application by using the Virtual Earth 6.0 map control in Microsoft
Visual Studio 2005. You program a Web page in the application by using client-side
JavaScript code. When you load the Web page, it returns an error message. You are unable to identify the point of failure in the code. You need to identify the line at which the code fails by executing the client-side JavaScript code step by step. Which code segment should you use?

• A. function GetMap(){ try{ map = new VEMap('myMap'); map.LoadMap(new
  VELatLong(-33.85,19),8,'h' ,false); } catch(e){ debugger; alert(e.message); } }
• B. function GetMap(){ try{ map = new VEMap('myMap'); map.LoadMap(new
  VELatLong(-33.85,19),8,'h' ,false); } catch(e){ alert(e.message); } }
• C. function GetMap(){ try{ debugger; map = new VEMap('myMap');
  map.LoadMap(new VELatLong(-33.85,19),8,'h' ,false); } catch(e){ alert(e.message); }
  }
• D. function GetMap(){ try{ map = new VEMap('myMap'); map.LoadMap(new
  VELatLong(-33.85,19),8,'h' ,false); debugger; } catch(e){ alert(e.message); } }

A news channel wants to display live traffic incident information for a city on a Web site.
You develop a three-tier architecture. The Microsoft MapPoint Web Service delivers traffic information that is managed by a user-defined class. The class acts as a SOAP-AJAX connector. Users interact with a Virtual Earth 6.0 map that is already loaded.
You need to ensure that the traffic incident information is displayed on a new layer of the
Virtual Earth map as the map is navigated by the users.
Which sequence of actions should you perform? (To answer, move all the actions from the list of actions to the answer area and arrange them in the correct order.)

You need to create a tile source specification that meets the following requirements:
It uses three tile servers named s0, s1, and s2.
It follows the standard Virtual Earth 6.0 numbering scheme.
It ensures that the tiles are visible in all the view types.
Which tile source parameter should you use within the tile source specification?

• A. http: //%4.yourserver.net/tiles/%2%1.jpg
• B. http: //%2.yourserver.net/tiles/%1%4.jpg
• C. http: //%1.yourserver.net/tiles/%4.jpg
• D. http: //%1.yourserver.net/tiles/%2%4.jpg

The location data of your company branch offices is stored as description and title in pushpins on a Virtual Earth 6.0 map.
You need to ensure that the data is displayed in a data panel named BranchInfo on top of the map every time a user moves the mouse over the pushpin.
What should you do? (To answer, move all the actions from the list of actions to the answer area and arrange them in the correct order.)
