A)1,2
B)2,3
C)3,4
D)2,5

Accepted Answer

The .NET Framework is made up of the Common Language Runtime (CLR) and the Framework Class Library (FCL). The CLR is the execution engine that handles running applications, and the FCL provides a vast library of reusable types, classes, and interfaces.

Question 9

Which of the following assemblies can be stored in Global Assembly Cache?
A)Private Assemblies
B)Friend Assemblies
C)Shared Assemblies
D)Public Assemblies

Accepted Answer

The Global Assembly Cache (GAC) is a machine-wide code cache designed for storing assemblies specifically designated to be shared by several applications on the computer. Shared Assemblies are the ones that can be installed into the GAC, allowing them to be shared among multiple applications.

Question 10

Code that targets the Common Language Runtime is known as
A)Unmanaged
B)Distributed
C)Legacy
D)Managed code

Accepted Answer

Managed code is the term used for code that is executed by the Common Language Runtime (CLR) in the .NET framework. It benefits from features such as garbage collection, type safety, and interoperability.

Question 11

Which of the following statements is correct about the .NET Framework?
A)NET Framework uses DCOM for achieving language interoperability.
B)NET Framework is built on the DCOM technology.
C)NET Framework uses DCOM for making transition between managed and unmanaged code.
D)NET Framework uses DCOM for creating unmanaged applications.

Accepted Answer

The .NET Framework uses COM Interop, not DCOM, to facilitate interaction between managed and unmanaged code. DCOM is not used for language interoperability or creating unmanaged applications in .NET.

Question 12

Which of the following benefits do we get on running managed code under CLR?1. Type safety of the code running under CLR is assured.2. It is ensured that an application would not access the memory that it is not authorized to access.3. It launches separate process for every application running under it.4. The resources are Garbage collected.
A)Only 1 and 2

Question 17

In C#, a subroutine is called a ________.
A)Function
B)Metadata
C)Method
D)Managed code

Accepted Answer

In C#, a subroutine is referred to as a "Method." Methods are blocks of code that perform specific tasks and can be called upon to execute those tasks when needed.

Question 18

All C# applications begin execution by calling the _____ method.
A)Class()
B)Main()
C)Submain()
D)Namespace

The entry point for all C# applications is the Main() method, from which execution starts.

Question 19

A _______ is an identifier that denotes a storage location
A)Constant
B)Reference type
C)Variable
D)Object

Accepted Answer

A variable is an identifier used in programming languages to denote a storage location that can hold values. Constants, reference types, and objects have different roles in programming. Constants refer to fixed values that cannot be altered during the execution of a program, reference types refer to references to memory locations where data is stored, and objects are instances of classes in object-oriented programming.

Question 20

_________ are reserved, and cannot be used as identifiers.
A)Keywords
