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

A Virtual Earth 6.0 application loads locations from a local Microsoft SQL Server 2005 database. You update locations in the database manually. You plan to automate the manual process. You need to ensure that the automation process updates the maximum number of locations in the least amount of time. What should you do?

• A. Call the Find method for each location by using Microsoft MapPoint Web Service.
• B. Push all locations to Customer Data Services by using the BatchGeocodeSpecification class, and retrieve the results.
• C. Push all locations to Customer Data Services by using the UploadSpecification class, and retrieve the results.
• D. Call the FindAddress method for each location by using Microsoft MapPoint Web
  Service.

You deploy a Virtual Earth 6.0 application that uses Microsoft ASP.NET Asynchronous
JavaScript and XML (AJAX) implementation to retrieve data.
The myAjaxCallback function evaluates any AJAX response. The function contains the following code segment. (Line numbers are included for reference only.)
0 1 function myAjaxCallback (){
0 2 if (xmlHttp.readyState == 4){
0 3 ...
0 4 }
0 5 }
At the time the request was made, the server was overloaded. When the server processed the AJAX request, the server returned an error message.
You need to ensure that the application does not produce a fatal exception due to the error generated from the AJAX response.
Which code segment should you insert at line 03?

• A. try{ eval(xmlHttp.responseText); } catch(error){ if(xmlHttp.status == 200){ eval(xmlHttp.responseText); } }
• B. try{ eval(xmlHttp.responseText); } catch(error){ eval(xmlHttp.responseXML); }
• C. try{ eval(xmlHttp.responseText); } catch(error){ // Update user with status here. }
• D. If(xmlHttp.status == 200){ eval(xmlHttp.responseText); } else{ // Update user with status here. }

You are creating a browser-based Web application by using Virtual Earth 6.0 map control.
A Web page of the application has a map and a list of locations.
When a user selects a location from the list, the application must meet the following requirements:
A default view of the selected location is loaded.
The selected location is centered.
The selected location appears in the three-dimensional mode, at an oblique pitch, and heads due north.
You need to program Virtual Earth map control to ensure that the requirements are met.
Which code segment should you use?

• A. var defView1= new VEMapViewSpecification(new VELatLong(40.68,-74.04), 16, 360, -
  4 5, 0); map.SetMapMode(VEMapMode.Mode3D); map.SetMapView(defView1);
• B. var defView1= new VEMapViewSpecification(new VELatLong(40.68,-74.04), 16, 360,
  4 5, 0); map.Loadmap(defView1); map.SetMapMode(VEMapMode.Mode3D);
• C. var defView1= new VEMapViewSpecification(new VELatLongRectangle (40.88,-73.8,
  4 0.48,-74.28), 16, 360, -45, 0); map.SetMapMode(VEMapMode.Mode3D);
  map.SetMapMode(defView1);
• D. var defView1= new VEMapViewSpecification(new VELatLongRectangle (40.88,-73.8,
  4 0.48, -74.28), 16, 360, 45, 0); map.Loadmap(defView1);
  map.SetMapMode(VEMapMode.Mode3D);

Your companys Web site has a Virtual Earth 6.0 map. You create custom buttons. You need to ensure that Web site users are able to pan the map to the north-east direction.
What should you do?

• A. Use VEMap.Pan with delta x < 0 and delta y > 0.
• B. Use VEMap.Pan with delta x > 0 and delta y < 0.
• C. Use VEMap.Pan with delta x < 0 and delta y < 0.
• D. Use VEMap.Pan with delta x > 0 and delta y > 0.
