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 = {
  0:{
  ID: 123,
  Latitude: 40.0,
  Longitude: -74.0,
  Address: " 123 Main St "
  }
  };
• B.var results = {
  ID: 123,
  Latitude: 40.0,
  Longitude: -74.0,
  Address: " 123 Main St ."
  };
• C.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 .";
• D.var results = new Array();
  results[0] = 123;
  results[1] = 40.0;
  results[2] = -74.0;
  results[3] = " 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 minimum bounding rectangle of the polygon and verify whether the location of the new pushpin lies inside the minimum bounding rectangle.
• C.Calculate the convex hull of all pushpins and verify whether the location of the new pushpin lies outside the convex hull.
• D.Calculate whether the location of the new pushpin overlaps the center point of all pushpins.

You are creating a Virtual Earth 6.0 application. The application will use data that is stored in the Microsoft MapCruncher output format.
The MapCruncher output is defined in the following manner:
var tileSrc =
http://dev.live.com/virtualearth/sdk/layers/layer1
You need to ensure that the application displays the data as a new layer on the Virtual
Earth map.
Which code segment should you use?

• A.var tileSourceSpec = new VETileSourceSpecification("layer1/%4.png", tileSrc); map.AddTileLayer(tileSourceSpec, true);
• B.var tileSourceSpec = new VETileSourceSpecification("layer1", tileSrc + /%1.png); map.AddTileLayer(tileSourceSpec, true);
• C.var tileSourceSpec = new VETileSourceSpecification("layer1", tileSrc + /%4); map.AddTileLayer(tileSourceSpec, true);
• D.var tileSourceSpec = new VETileSourceSpecification("layer1", tileSrc + "/%4.png"); map.AddTileLayer(tileSourceSpec, true);

Your company plans to implement a store locator on its Web site. You need to center a
Virtual Earth 6.0 map on a selected store location. What are two possible methods you can use to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

• A.VEMap.StartContinousPan
• B.VEMap.SetMapMode
• C.VEMap.SetCenterAndZoom
• D.VEMap.PanToLatLong
• E.VEMap.SetPitch

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