What is MVC architecture?

  1. Model-View-Controller

  2. Make-Value-Case

  3. Make-Value-Controller

  4. Model-Value-Controller
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

MVC (Model-View-Controller) is a design pattern that separates application logic into three interconnected components: Model (data/business logic), View (presentation/UI), and Controller (input handling and coordination). This separation enables modular development and maintenance.

Which is not an element of manifest.xml?

  1. FeatureManifests

  2. CodeAccessSecurity

  3. CabinetNameTemplate

  4. Assembly
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

CabinetNameTemplate is not a valid element in manifest.xml for SharePoint solution packages. The manifest.xml file contains elements like FeatureManifests, CodeAccessSecurity, and Assembly which define the solution structure and security permissions. CabinetNameTemplate is related to CAB file naming but is not part of the manifest schema itself.

  1. MVC

  2. View Model

  3. Small Talk

  4. Core page
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Struts implements the Model-View-Controller architectural pattern, separating application logic (Model), presentation (View), and request handling (Controller). This separation improves maintainability, enables parallel development, and follows standard web application architecture.

You're designing a paint application and as part of the user interface you have a toolbar along the left hand side of the screen. Each of the icons on the toolbar has different actions when you are using different tools. The way you've structured it, the application is required to pass commands from one object to another. When the appropriate object receives the command, it handles the request. This is an example of which pattern?

  1. Command

  2. Chain of Responsibility

  3. Adapter

  4. Interpreter

  5. Strategy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Chain of Responsibility pattern passes a request along a chain of handling objects, where each object can either handle the request or pass it to the next. This matches the toolbar scenario where commands are passed from one object to another until the appropriate handler processes it. The Command pattern encapsulates requests as objects but doesn't inherently chain them. Adapter converts interfaces, Interpreter evaluates language syntax, and Strategy encapsulates algorithms - none of which fit this command-passing behavior.

In order to use a value editor for business rules in rule studio, you must develop this editor in;

  1. javascript

  2. SWT

  3. .Net

  4. swing
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Value editors for business rules in Rule Studio must be developed using Java Swing, as Rule Studio is built on the Eclipse platform which uses SWT but custom editors require Swing components. The editor framework in Rule Studio expects Swing-based UI components for value editing. JavaScript and .Net are not supported for this purpose.

  1. Sets the zoom level

  2. Defines how many markers can be placed on the map

  3. Defines de version of google map api to be used

  4. Indicates the number of vertical controls available to the user

Which is the correct way to create a GMarker?

  1. var marker = new GMarker(point);

  2. var marker = new GoogleGMarker(point);

  3. var marker = map.overlayMarker(new GMarker(point));

  4. var marker = new Marker(point,"G");
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The GMarker class is instantiated with a GLatLng point object as its constructor argument. This is the standard syntax for creating markers in Google Maps API v2. Options B, C, and D either use incorrect class names or non-existent methods.

Which of the following is NOT a default supported map type in the version 2 of Google Maps API?

  1. G_NORMAL_MAP

  2. G_SATELLITE_MAP

  3. G_HYBRID_MAP

  4. G_STREET_MAP
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In Google Maps API v2, the three default map types were G_NORMAL_MAP (standard roadmap), G_SATELLITE_MAP (satellite imagery), and G_HYBRID_MAP (satellite with overlay). G_STREET_MAP was not a built-in map type in version 2 - Street View was a separate feature introduced later.

Which is the correct way to obtain a given point in the map, knowing the latitude and longitude of the point?

  1. var myGeographicCoordinates = new GPointM(new Lat(longitude),new Lng(longitude));

  2. var myGeographicCoordinates = new GLatLng(myLatitude, myLongitude);

  3. var myGeographicCoordinates = new GLatLng(GMarker.Lat(),GMarker.Lng())

  4. var myGeographicCoordinates = new GLatLng(GMarker.getLat(),GMarker.getLng())
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The GLatLng constructor takes latitude and longitude as parameters in that order. This is the correct way to create a geographic coordinate point in Google Maps API v2. Options A uses incorrect class names, and C/D incorrectly reference GMarker methods.

Which is the correct way of make a marker draggable?

  1. var Marker = new GMarker(center,true);

  2. var marker = new GMarker(center, {draggable: true});

  3. var Marker = new GMarker(center, enableDragAndDrop = true);

  4. var Marker = new GMarker(center, new draggableMarker(me,true));
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In the Google Maps API (specifically GMarker in version 2), the second parameter accepts a GMarkerOptions object, where setting the draggable property to true enables marker dragging. The other options use incorrect syntax, incorrect parameters, or invalid constructors.
