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

You are creating a Web application by using the Virtual Earth 6.0 map control in the
Microsoft Visual Studio environment. A Web page in the application is programmed by using the client-side JavaScript code. You insert break points at appropriate locations within the code. When you debug the application, you find that you are able to step into the server-side code. However, you are unable to step into the client-side JavaScript code.
You need to debug the client-side JavaScript code. What should you do?

• A.In Visual Studio, select the Attach to Process option from the Debug menu. Then attach the debugger to the Microsoft Internet Explorer process.
• B.In Microsoft Internet Explorer, select the Enable Display a notification about every script error option in the Internet Options dialog box.
• C.In Microsoft Internet Explorer, clear the Disable Script Debugging (Internet Explorer) option in the Internet Options dialog box.
• D.In the client-side JavaScript code, insert the Debugger command before each break point.

Each sales executive in your company is assigned a sales territory. You need to add the sales territories as a vector area to a Virtual Earth 6.0 map. What are two possible geometry types you can add to the Virtual Earth map to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

• A.Polygon
• B.Shape with a polygon
• C.Pushpin
• D.Polyline
• E.Tile

You are writing a code segment for a Virtual Earth 6.0 application. The code segment returns data for multiple locations to a client-side JavaScript function that makes the initial request.
The returned data contains the following properties for each location:
ID
Latitude
Longitude
Address
You need to format all locations and their properties in JavaScript Object Notation (JSON) format.
Which code segment should you use?

• A.var results = new Array();
  results[0] = 123;
  results[1] = 40.0;
  results[2] = -74.0;
  results[3] = " 123 Main St .";
• B.var results = {
  ID: 123,
  Latitude: 40.0,
  Longitude: -74.0,
  Address: " 123 Main St ."
  };
• C.var results = {
  0:{
  ID: 123,
  Latitude: 40.0,
  Longitude: -74.0,
  Address: " 123 Main St "
  }
  };
• D.var results = new Array();
  results[0] = new Array();
  results[0][0] = 123;
  results[0][1] = 40.0;
  results[0][2] = -74.0;
  results[0][3]= " 123 Main St .";

You need to add a default pushpin as a shape to the base map layer at a specific latitude and longitude. Which code segment should you use?

• A.var shape = new VEShape(VEShapeType.Pushpin, map.GetCenter()); shape.SetTitle('My pushpin'); shape.SetDescription('This is a default shape'); map.AddShape(shape);
• B.var shape = map.AddPushpin(map.GetCenter()); shape.SetTitle('My pushpin'); shape.SetDescription('This is a default shape');
• C.var shapeLayer = new VEShapeLayer(); map.AddShapeLayer(shapeLayer); var shape = new VEShape(VEShapeType.Pushpin, new VELatLong(latitude,longitude)); shape.SetTitle('My pushpin'); shape.SetDescription('This is a default shape'); shapeLayer.AddShape(shape);
• D.var shape = new VEShape(VEShapeType.Pushpin, new VELatLong(0,0)); shape.SetTitle('My pushpin'); shape.SetDescription('This is a default shape'); shape.SetPoints([new VELatLong(latitude,longitude)]); map.AddShape(shape);
