Microsoft 070-544 real exam prep : TS: Ms Virtual Earth 6.0, Application Development

You create a Microsoft MapPoint Web Service application that accepts routes from users.
You need to find points of interest that are within one mile of a route or within three miles of the endpoints of the route. What are two possible ways to achieve the goal? (Each correct answer presents a complete solution. Choose two.)

• A. findNearRouteSpec.Distance = 1; findResults =
  findService.FindNearRoute(findNearRouteSpec); foundLocations.Add(findResults); findNearbySpec.Distance = 3; findNearbySpec.LatLong = startLatLong; findResults = findService.FindNearby(findNearbySpec); foundLocations.Add(findResults); findNearbySpec.LatLong = endLatLong; findResults =
  findService.FindNearby(findNearbySpec); foundLocations.Add(findResults);
• B. findNearRouteSpec.Distance = 1; findResults =
  findService.FindNearRoute(findNearRouteSpec); foundLocations.Add(findResults); findNearbySpec.Distance = 3; foreach (FindResult findResult in findResults.Results) { findNearbySpec.LatLong = findResult.FoundLocation.LatLong; findResults = findService.FindNearby(findNearbySpec); foundLocations.Add(findResults); }
• C. findNearRouteSpec.Distance = 1; findResults =
  findService.FindNearRoute(findNearRouteSpec); foundLocations.Add(findResults); findNearbySpec.Distance = 3; foreach (Segment segment in route.Itinerary.Segments) { foreach (Direction direction in segment.Directions) { findNearbySpec.LatLong = direction.LatLong; findResults = findService.FindNearby(findNearbySpec); foundLocations.Add(findResults); } }
• D. findNearRouteSpec.Distance = 1; findResults =
  findService.FindNearRoute(findNearRouteSpec); foundLocations.Add(findResults); findNearbySpec.Distance = 3; foreach (Segment segment in route.Itinerary.Segments) { findNearbySpec.LatLong = segment.Waypoint.Location.LatLong; findResults = findService.FindNearby(findNearbySpec); foundLocations.Add(findResults); }

DRAG DROP
The location data of your company branch offices is stored as description and title in pushpins on a Virtual Earth 6.0 map.
You need to ensure that the data is displayed in a data panel named BranchInfo on top of the map every time a user moves the mouse over the pushpin.
What should you do? (To answer, move all the actions from the list of actions to the answer area and arrange them in the correct order.)

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

You are updating a Virtual Earth 6.0 store locator. A database table named Stores contains the City and State fields. A Microsoft SQL Server 2005 function named CalculateDistance measures the distance between two points.
The store locator contains a stored procedure named LookupStores that retrieves the names of stores located in a given city and state. The city and state are passed in as parameters to the stored procedure.
You need to extend the store locator to support a proximity search within a given radius.
Which two tasks should you perform? (Each correct answer presents part of the solution.
Choose two.)

• A. Add Latitude and Longitude fields to the Stores table.
• B. Create a new stored procedure that uses CalculateDistance along with the result set from the LookupStores stored procedure.
• C. Extend the LookupStores stored procedure to use CalculateDistance.
• D. Add a Radius field to the Stores table.
• E. Add a Distance field to the Stores table.
• F. Create a new stored procedure that uses CalculateDistance along with the entire data set from the Stores table.

You are creating a Virtual Earth 6.0 application.
A Web page of the application contains the following code segment.
control = document.createElement ("div");
control.id = " CustomControl ";
A custom control must be added on top of the map on the Web page.
You need to ensure that the custom control responds only to its own mouse-click events.
Which code segment should you use?

• A. control.innerHTML = "<input type='button' value='Click' onclick =' ClickHandler ()' />"; map.AddControl (control);
• B. control.innerHTML = "<input type='button' value='Click' />"; document.getElementById
  ('Map'). appendChild (control); document.getElementById (' CustomControl '). attachEvent
  (" onclick ", ClickHandler );
• C. control.innerHTML = "<input type='button' value='Click' />"; map.AddControl (control); map.AttachEvent (" onclick ", ClickHandler );
• D. control.innerHTML = "<input type='button' value='Click' onclick =' ClickHandler ()' />"; document.getElementById ('Map'). appendChild (control);
