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 are creating a custom tile set by using Microsoft MapCruncher. The tile set must overlay a weather map image in a Virtual Earth 6.0 application by using MapCruncher.
You need to perform two tasks before using MapCruncher to create the custom tile set.
Which two tasks should you perform? (Each correct answer presents part of the solution.
Choose two.)

• A. Split the weather map image into tiles.
• B. Obtain low resolution weather map images for low zoom levels and high resolution weather map images for high zoom levels.
• C. Apply the proper alpha filter to the weather map image to display any transparent portions on the Virtual Earth map.
• D. Obtain the latitude and longitude coordinates for the corners of the weather map image.

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 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);
• 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);

You need to create a cluster of pushpins for a large dataset that takes the least amount of time to load on a Virtual Earth 6.0 map. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

• A. Start clustering by using the VEMap.onchangeview event.
• B. Implement client-side clustering by using JavaScript.
• C. Start clustering by using the VEMap.onendzoom event.
• D. Implement server-side clustering by using Microsoft ASP.NET 2.0.

You are creating a Virtual Earth 6.0 application.
A Web page of the application contains the following code segment.
control = document.createElement("div");
control.id = "CustomControl";
A custom control must be added on top of the map on the Web page.
You need to ensure that the custom control responds only to its own mouse-click events.
Which code segment should you use?

• A. control.innerHTML = "<input type='button' value='Click' />";
  document.getElementById('Map').appendChild(control);
  document.getElementById('CustomControl').attachEvent("onclick", ClickHandler);
• B. control.innerHTML = "<input type='button' value='Click' />"; map.AddControl(control); map.AttachEvent("onclick", ClickHandler);
• C. control.innerHTML = "<input type='button' value='Click' onclick='ClickHandler()' />"; map.AddControl(control);
• D. control.innerHTML = "<input type='button' value='Click' onclick='ClickHandler()' />"; document.getElementById('Map').appendChild(control);
