Microsoft TS: Ms Virtual Earth 6.0, Application Development Sample Questions:
1. 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 + /%4); map.AddTileLayer(tileSourceSpec, true);
B) var tileSourceSpec = new VETileSourceSpecification("layer1", tileSrc + "/%4.png"); map.AddTileLayer(tileSourceSpec, true);
C) var tileSourceSpec = new VETileSourceSpecification("layer1", tileSrc + /%1.png); map.AddTileLayer(tileSourceSpec, true);
D) var tileSourceSpec = new VETileSourceSpecification("layer1/%4.png", tileSrc); map.AddTileLayer(tileSourceSpec, true);
2. 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) If(xmlHttp.status == 200){ eval(xmlHttp.responseText); } else{ // Update user with status here. }
B) try{ eval(xmlHttp.responseText); } catch(error){ eval(xmlHttp.responseXML); }
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); } }
3. You are creating a Web application by using the Virtual Earth 6.0 map control. A Web page of the application provides navigational aid to the users.
When the Web page loads, it must meet the following requirements:
The map must appear in the two-dimensional mode.
The users must be able to view the roads on the map and navigate through the map.
The users must not be able to change the map to the three-dimensional mode.
You need to ensure that the Web page meets the requirements.
Which code segment should you use?
A) map.LoadMap(new VELatLong(-33.85,18.6),11,'r', true, VEMapMode.Mode2D, true);
B) map.LoadMap(new VELatLong(-33.85,18.6), 11,'r', true, VEMapMode.Mode2D, false);
C) map.LoadMap(new VELatLong(-33.85,18.6),11,'r', false, VEMapMode.Mode2D, false);
D) map.LoadMap(new VELatLong(-33.85,18.6),11,'r', false, VEMapMode.Mode2D, true);
4. Your Microsoft MapPoint Web Service (MWS) User Id is 124566, and your MWS password is P@ssw0rd. You need to use MWS to create an application. Which code segment should you use?
A) System.Net.NetworkCredential appCredential = new
System.Net.NetworkCredential("124566", "P@ssw0rd");
B) System.Security.Principal.NTAccount appCredential = new
System.Security.Principal.NTAccount("124566", "P@ssw0rd");
C) System.EnterpriseServices.SecurityIdentity appCredential = new
System.EnterpriseServices.SecurityIdentity ("124566", "P@ssw0rd");
D) System.Security.Principal.GenericIdentity appCredential = new
System.Security.Principal.GenericIdentity ("124566", "P@ssw0rd");
5. You are creating a Web application by using the Virtual Earth 6.0 map control in the
Microsoft Visual Studio environment. A Web page in the application is programmed by using the client-side JavaScript code. You insert break points at appropriate locations within the code. When you debug the application, you find that you are able to step into the server-side code. However, you are unable to step into the client-side JavaScript code.
You need to debug the client-side JavaScript code. What should you do?
A) In Microsoft Internet Explorer, clear the Disable Script Debugging (Internet Explorer) option in the Internet Options dialog box.
B) In the client-side JavaScript code, insert the Debugger command before each break point.
C) In Visual Studio, select the Attach to Process option from the Debug menu. Then attach the debugger to the Microsoft Internet Explorer process.
D) In Microsoft Internet Explorer, select the Enable Display a notification about every script error option in the Internet Options dialog box.
