Microsoft 070-544 Exam Syllabus Topics:

Microsoft TS: Ms Virtual Earth 6.0, Application Development Sample Questions:

1. A Virtual Earth 6.0 application loads locations from a local Microsoft SQL Server 2005 database. You update locations in the database manually. You plan to automate the manual process. You need to ensure that the automation process updates the maximum number of locations in the least amount of time. What should you do?

A) Call the FindAddress method for each location by using Microsoft MapPoint Web
Service.
B) Push all locations to Customer Data Services by using the BatchGeocodeSpecification class, and retrieve the results.
C) Push all locations to Customer Data Services by using the UploadSpecification class, and retrieve the results.
D) Call the Find method for each location by using Microsoft MapPoint Web Service.

2. Your companys Web site has a Virtual Earth 6.0 map. You create custom buttons. You need to ensure that Web site users are able to pan the map to the north-east direction.
What should you do?

A) Use VEMap.Pan with delta x > 0 and delta y > 0.
B) Use VEMap.Pan with delta x > 0 and delta y < 0.
C) Use VEMap.Pan with delta x < 0 and delta y < 0.
D) Use VEMap.Pan with delta x < 0 and delta y > 0.

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

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

5. 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("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"]);
B) 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"]);
C) String [] keys = Results[i].Keys; String curKey; For (int i = 0; i < keys.length; i++){ curKey = keys[i]; curItem.Add(curKey, Results[i][curKey]); }
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"]);
