You have created and tested an application by using Microsoft MapPoint Web Service
(MWS). You need to deploy the live version of the application. Which Web reference should you add to your application?
- A. http: //service.mappoint.net/standard-30/mappoint.wsdl
- B. http: //staging.mappoint.net/standard-30/mappoint.asmx
- C. http: //staging.mappoint.net/standard-30/mappoint.wsdl

You are creating a Virtual Earth 6.0 application that retrieves locations from a Microsoft SQL Server 2005 database.
A stored procedure will be used to retrieve only locations that lie within the currently displayed map area. You need to define the boundary within which the locations displayed on the map must lie. How should you define the boundary?
- A. points represented by the bottom-right and top-left latitude and longitude coordinates
- B. the center point of a circle whose radius is equal to the size of the map based on pixel coordinates
- C. the center point of a circle whose radius is equal to the size of the map based on latitude and longitude coordinates
- D. points represented by the bottom-right and top-left pixel coordinates
Correct Answer: A 🗳️
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){ // Update user with status here. }
- B. If(xmlHttp.status == 200){ eval(xmlHttp.responseText); } else{ // Update user with status here. }
- C. try{ eval(xmlHttp.responseText); } catch(error){ eval(xmlHttp.responseXML); }
- D. try{ eval(xmlHttp.responseText); } catch(error){ if(xmlHttp.status == 200){ eval(xmlHttp.responseText); } }
Correct Answer: B 🗳️
