Which of the following is not correct about StoryBoard in Silverlight?

  1. Controls animations with a timeline, and provides object and property targeting information for its child animations

D Correct answer
Explanation

Storyboards CAN be nested within each other in Silverlight - this is a common pattern for complex animations. Option A correctly describes Storyboard's timeline-based animation control. Option B is correct - Storyboard serves as a container. Option C accurately lists the interactive control methods available.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Silverlight is intentionally a subset of WPF, designed for cross-platform web delivery with limited functionality. WPF offers full desktop application capabilities including 3D, advanced text, and full OS integration that Silverlight lacks. They serve different purposes.

Which of the following is not part of built-in layout containers in Silverlight?

  1. Canvas

  2. DockPanel

  3. Grid

  4. StackPanel
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

DockPanel is NOT a built-in Silverlight layout container - it exists only in WPF. Canvas (absolute positioning), Grid (row/column layout), and StackPanel (sequential stacking) are all standard Silverlight containers. Silverlight's layout system is intentionally simplified.

Silverlight enables you to customize controls in several ways. Select the option that is not applicable to control customization in Silverlight.

  1. ContentTemplate

  2. Styles

  3. CSS

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

Silverlight uses XAML-based templating, not web CSS. ContentTemplate defines content presentation, ControlTemplate defines entire control structure, and Styles provide property setters. CSS is a web technology completely separate from Silverlight's XAML styling system.

Which of the following is not introduced as new features in Silverlight 3.0?

  1. Printing

  2. 3D Effects

  3. SaveFileDialog

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Silverlight 3.0 introduced several major features including 3D Effects (for perspective transforms), Out-of-Browser Support (allowing apps to run offline), and SaveFileDialog (for user-initiated file saving). Printing was actually introduced in Silverlight 4, not Silverlight 3.0, making it the correct answer to what was NOT a new feature in version 3.0.

Which of the following is not installed by Silverlight 3 Tools for Visual Studio 2008

  1. Silverlight SDK

  2. XAMLPad

  3. Silverlight developer runtime

  4. Silverlight Tools
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Silverlight 3 Tools for Visual Studio 2008 installs the Silverlight SDK, Silverlight developer runtime, and Silverlight Tools (project templates and Visual Studio integration). XAMLPad is a standalone tool that is NOT included with the Silverlight 3 Tools installation - it's a separate utility for testing XAML markup independently.

Which of the following is not a Silverlight tool?

  1. XamlPadX

  2. Visual C# 2008 Expression Edition

  3. Expression Blend

  4. Visual Web Developer 2008 Express Edition
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

XamlPadX is a XAML editing tool. Expression Blend is a design tool for Silverlight/WPF applications. Visual Web Developer 2008 Express Edition is a free IDE that supports Silverlight development. Visual C# 2008 Expression Edition does not exist as a product - there's no C# Express Edition from Expression (Expression Studio is for designers, not programming languages).

Which of the following is used for enabling cross-domain connectivity for Silverlight applications to access network resources?

  1. crossdomain.xml

  2. Web.config

  3. App.xaml

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

Silverlight uses policy files to enable cross-domain network access. While crossdomain.xml is supported (for Flash compatibility), the primary and more flexible Silverlight-specific policy file is clientaccesspolicy.xml. Web.config is for ASP.NET configuration, and App.xaml is for Silverlight application settings - neither handles cross-domain policy.

Which of the following is not installed by Silverlight 3 Tools for Visual Studio 2008?

  1. Silverlight SDK

  2. XAMLPad

  3. Silverlight developer runtime

  4. Silverlight Tools
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This is a duplicate of question 140642. Silverlight 3 Tools for Visual Studio 2008 installs the SDK, developer runtime, and Tools. XAMLPad is NOT included in this installation - it's a separate standalone XAML testing utility.

Which of the following statements is not true about Deep Zoom in Silverlight?

  1. Deep Zoom uses multi-resolution images to achieve a high frame-rate and fast open experience for images

  2. On the initial load, Deep Zoom takes a bit more time to load image data for large images

  3. Deep Zoom uses spring animations, which gives users the impression of a smooth movement (pan or zoom) around image

  4. A Deep Zoom image is typically composed of 256x256 size tiles of JPEG or PNG images at different resolutions that make up an image pyramid
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Deep Zoom in Silverlight uses multi-resolution image pyramids (256x256 tiles) for performance, enabling fast initial load and smooth animations. Statement B claims Deep Zoom takes more time to load initially for large images, which contradicts the core purpose of Deep Zoom - it's specifically designed to load quickly by only loading necessary tiles at the current zoom level, not the entire large image.

Which of the following is not correct about XAP file in Silverlight?

  1. .xap file is a Silverlight-based application package (.xap) that is generated when the Silverlight project is built

  2. .xap file is encrypted for security and we can not view its contents

  3. .xap file includes AppManifest.xaml, compiled output assembly of the Silverlight project (.dll) and any other resource files referred by the Silverlight application

  4. Web pages like .aspx files and .html files use the Silverlight components by loading the .xap files using the <object> tag in the HTML or by using <asp:Silverlight> tag in the ASP.NET pages
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The .xap file is a Silverlight application package generated at build time, containing AppManifest.xaml, compiled assemblies (.dll), and resources. Web pages load .xap files using object or asp:Silverlight tags. Statement B incorrectly claims .xap files are encrypted - they are actually just ZIP archives that can be opened and viewed with any ZIP utility.
