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

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: //staging.mappoint.net/standard-30/mappoint.asmx
• B. http: //service.mappoint.net/standard-30/mappoint.asmx
• C. http: //staging.mappoint.net/standard-30/mappoint.wsdl
• D. http: //service.mappoint.net/standard-30/mappoint.wsdl

Your company displays apartments as pushpins on a Virtual Earth 6.0 map. You need to display the images of the apartments along with associated information in a tabular format within a pushpin pop-up bubble. What should you do?

• A. Use the VEShape.SetDescription method with the object information as HTML to set the information in the pop-up bubble.
• B. Use the VEShape.SetMoreInfoUrl method to import object information as HTML to set the information in the pop-up bubble.
• C. Use the VEShape.SetDescription method with the object information as plain text to set the information in the pop-up bubble.
• D. Use the VEShape.SetMoreInfoUrl method to import object information as plain text to set the information in the pop-up bubble.

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

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