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 = 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 .";
• C. var results = {
  0:{
  ID: 123,
  Latitude: 40.0,
  Longitude: -74.0,
  Address: " 123 Main St "
  }
  };
• D. var results = {
  ID: 123,
  Latitude: 40.0,
  Longitude: -74.0,
  Address: " 123 Main St ."
  };

You add a new pushpin to a Virtual Earth 6.0 map. You are creating an algorithm to calculate the polygon representation of a pushpin cluster. You write a step to verify that the pushpin belongs to the cluster. You need to identify whether to recalculate the polygon representation. What should you do?

• A. Calculate the bounding box of all pushpins and verify whether the location of the new pushpin lies inside the bounding box.
• B. Calculate the convex hull of all pushpins and verify whether the location of the new pushpin lies outside the convex hull.
• C. Calculate whether the location of the new pushpin overlaps the center point of all pushpins.
• D. Calculate the minimum bounding rectangle of the polygon and verify whether the location of the new pushpin lies inside the minimum bounding rectangle.

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 = 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);
• C. var shape = map.AddPushpin(map.GetCenter()); shape.SetTitle('My pushpin'); shape.SetDescription('This is a default shape');
• D. 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);

DRAG DROP - (Topic 0)
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 define a callback function that updates the data on a Virtual Earth 6.0 map. You need to ensure that the callback function runs every time a user pans or zooms the Virtual Earth map. Which event should you attach to the Virtual Earth map?

• A. onloadmap
• B. oninitmode
• C. onobliquechange
• D. onmousemove
• E. onchangeview
