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

1. 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) Implement server-side clustering by using Microsoft ASP.NET 2.0.
D) Start clustering by using the VEMap.onendzoom event.

A news channel wants to display live traffic incident information for a city on a Web site.
You develop a three-tier architecture. The Microsoft MapPoint Web Service delivers traffic information that is managed by a user-defined class. The class acts as a SOAP-AJAX connector. Users interact with a Virtual Earth 6.0 map that is already loaded.
You need to ensure that the traffic incident information is displayed on a new layer of the
Virtual Earth map as the map is navigated by the users.
Which sequence of actions should you perform? (To answer, move all the actions from the list of actions to the answer area and arrange them in the correct order.)

3. You are creating a browser-based Web application by using Virtual Earth 6.0 map control.
A Web page of the application has a map and a list of locations.
When a user selects a location from the list, the application must meet the following requirements:
A default view of the selected location is loaded.
The selected location is centered.
The selected location appears in the three-dimensional mode, at an oblique pitch, and heads due north.
You need to program Virtual Earth map control to ensure that the requirements are met.
Which code segment should you use?

A) var defView1= new VEMapViewSpecification(new VELatLongRectangle (40.88,-73.8,
4 0.48, -74.28), 16, 360, 45, 0); map.Loadmap(defView1);
map.SetMapMode(VEMapMode.Mode3D);
B) var defView1= new VEMapViewSpecification(new VELatLong(40.68,-74.04), 16, 360,
4 5, 0); map.Loadmap(defView1); map.SetMapMode(VEMapMode.Mode3D);
C) var defView1= new VEMapViewSpecification(new VELatLong(40.68,-74.04), 16, 360, -
4 5, 0); map.SetMapMode(VEMapMode.Mode3D); map.SetMapView(defView1);
D) var defView1= new VEMapViewSpecification(new VELatLongRectangle (40.88,-73.8,
4 0.48,-74.28), 16, 360, -45, 0); map.SetMapMode(VEMapMode.Mode3D);
map.SetMapMode(defView1);

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) Dim appCredential As New System.EnterpriseServices.SecurityIdentity("124566",
"P@ssw0rd")
B) Dim appCredential = New System.Security.Principal.NTAccount("124566", "P@ssw0rd")
C) Dim appCredential As New System.Net.NetworkCredential("124566", "P@ssw0rd")
D) Dim appCredential As New System.Security.Principal.GenericIdentity("124566",
"P@ssw0rd")

Your customer is using a Virtual Earth 6.0 map. The pushpins on the map represent apartments.
You need to ensure that the customer can display the rooms in the apartments along with related information. The information must appear in a tabular format on a scratch pad.
Which sequence of four steps should you perform after loading the map? (To answer, move the four appropriate actions from the list of actions to the answer area and arrange them in the correct order.)
