MCTS - Microsoft Certified Technology Specialist .NET Application Development Questions and Answers

Question 1

A developer needs to ensure that a compiled .NET assembly can be shared across multiple applications on a single machine. Which of the following is a mandatory prerequisite for deploying an assembly to the Global Assembly Cache (GAC)?

Accepted Answer

The assembly must have a strong name.

Answer

To be installed in the Global Assembly Cache (GAC), an assembly must have a strong name. A strong name consists of the assembly's identity—its simple text name, version number, and culture information (if provided)—plus a public key and a digital signature. This ensures the uniqueness of the assembly and prevents conflicts.

Question 2

In the context of the .NET garbage collector, which generation is collected most frequently and contains newly allocated, short-lived objects?

Accepted Answer

Generation 0

Answer

The .NET garbage collector uses a generational approach to optimize performance. New objects are allocated in Generation 0. The GC collects Generation 0 most frequently because most objects are short-lived and can be reclaimed quickly. Objects that survive a Generation 0 collection are promoted to Generation 1, and those that survive a Generation 1 collection move to Generation 2.

Question 3

A developer is building an ASP.NET Web Forms application and needs to programmatically create and add dynamic controls to a page. In which of the following page life cycle events is it most appropriate to create these controls to ensure their view state is correctly managed on subsequent postbacks?

Accepted Answer

PreInit

Answer

The PreInit event is the earliest stage in the page life cycle where it is appropriate to create dynamic controls. Creating controls this early ensures they are part of the page's control tree and can properly participate in the rest of the life cycle, including the loading of view state and postback data.

Question 4

What is the primary role of the Common Intermediate Language (CIL) in the .NET Framework?

Accepted Answer

To serve as a common, platform-independent instruction set that all .NET languages compile into.

Answer

Common Intermediate Language (CIL), formerly known as MSIL, is the low-level, platform-independent instruction set into which all .NET source code (from languages like C#, VB.NET, etc.) is compiled. This CIL code is later compiled into native machine code by the Just-In-Time (JIT) compiler at runtime, enabling language interoperability and platform independence.

Question 5

You are developing a Windows Presentation Foundation (WPF) application and need to define a custom property for a UserControl that supports data binding, styling, and animation. Which type of property should you implement?

Accepted Answer

A dependency property.

Answer

Dependency properties are a specific type of property system provided by WPF. They are required for a property to support features like data binding, styling, animation, and property value inheritance. Standard CLR properties do not have this built-in infrastructure.
