The locations of the vehicles of your company are available as coordinates. You need to display only the current location of a vehicle on a Virtual Earth 6.0 base map layer. What are two possible code segments you can use to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

• A. map = new VEMap('myMap'); map.LoadMap(); layer = new VEShapeLayer(); map.AddShapeLayer(layer); shape = new VEShape(VEShapeType.Pushpin, new VELatLong(latitude, longitude)); layer.AddShape(shape);
• B. map = new VEMap('myMap'); map.LoadMap(); layer = new VEShapeLayer(); map.AddShapeLayer(layer); shape = new VEShape(VEShapeType.Pushpin, new VELatLong(longitude, latitude)); layer.AddShape(shape);
• C. map = new VEMap('myMap'); map.LoadMap(); shape = new VEShape(VEShapeType.Pushpin, new VELatLong(latitude, longitude)); map.AddShape(shape);
• D. map = new VEMap('myMap'); map.LoadMap(); map.AddPushpin(new VELatLong(longitude, latitude));
• E. map = new VEMap('myMap'); map.LoadMap(); map.AddPushpin(new VELatLong(latitude, longitude));

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

You are integrating third-party data into a Virtual Earth 6.0 application. The data that is retrieved from the third party is stored in an array named Results. The Results array is stored inside a Web handler. The data is stored in the following format.
R esults[0]["name"] = "A. Datum Corporation";
Results[0]["address"] = " 123 Main St. , New York , NY ";
Results[0]["latitude"] = "40.123";
Results[0]["longitude"] = "-70.456";
Results[0]["thumbnail"] = "http://www.adatum.com/st3465.jpg";
...
Results[x]
The Web handler uses the GeoRSSFeed class to accept items of type GeoRSSItem. The class contains the ToString() method that writes the GeoRSS feed to a string.
The Web handler GeoRSS integration is defined by the following code segment. (Line numbers are included for reference only.)
0 1 GeoRSSFeed feed = new GeoRSSFeed();
0 2 GeoRSSItem curItem;
0 3 for (int i = 0; i < Results.length; i++){
0 4 curItem = new GeoRSSItem();
0 5 ...
0 6 feed.Add(curItem);
0 7 }
0 8 // Write feed to HTTP Response
0 9 context.Write(feed.ToString());
The Web handler uses the GeoRSSItem class that contains the following code segment.
(Line numbers are included for reference only.)
1 0 public class GeoRSSItem {
1 1 public Dictionary < string, string > elements;
1 2 publ ic GeoRSSItem(){
1 3 elements = Dictionary < string, string > ();
1 4 }
1 5 public void Add(string pName, string pValue){
1 6 elements.Add(pName, pValue);
1 7 }
1 8 }
You need to encode the data inside the Results array into the GeoRSS format.
Which code segment should you insert at line 05?

• A. curItem.Add("name", Results[i]["name"]);
  curItem.Add("address", string.Format("{0}|{1}", _
  Results[i]["address"], _
  Results[i]["thumbnail"]);
  curItem.Add("latitude", Results[i]["latitude"]);
  curItem.Add("longitude", Results[i]["longitude"]);
• B. String [] keys = Results[i].Keys; String curKey; For (int i = 0; i < keys.length; i++){ curKey = keys[i]; curItem.Add(curKey, Results[i][curKey]); }
• C. curItem.Add("title", Results[i]["name"]); curItem.Add("description", string.Format("{0}|{1}",
  _ Results[i]["address"], _ Results[i]["thumbnail"]); curItem.Add("latitude",
  Results[i]["latitude"]); cur Item.Add("longitude", Results[i]["longitude"]);
• D. curItem.Add("title", Results[i]["name"]); curItem.Add("description", Results[i]["address"]); curItem.Add("latitude", Results[i]["latitude"]); curItem.Add("longitude",
  Results[i]["longitude"]); curItem.Add("icon", Results[i]["thumbnail"]);

You create a Web page that contains a Virtual Earth 6.0 map. You want to track how your users are interacting with the map.
You need to track the following usage data.
number of Virtual Earth transactions
zoom usage
map styles that are being used
Which two methods or events should you use? (Each correct answer presents part of the solution. Choose two.)

• A. scroll
• B. VEMap.Find
• C. VEMap.ShowInfoBox
• D. onchangeview
• E. onmousemove
