Q11.
What is metadata in .NET?

a.

A software execution environment

b.

A virtual machine for .NET programs

c.

A binary module containing IL code and metadata

d.

A special data block storing data type information for objects used in an assembly

Discuss
Answer: (d).A special data block storing data type information for objects used in an assembly Explanation:Metadata is a special data block that stores data type information describing the various objects used in an assembly.
Q12.
How are .NET assemblies executed?

a.

By the metadata block

b.

By the native code

c.

By the CLR, which loads the metadata into memory and compiles the IL code into native code using a just-in-time compiler

d.

By the .NET class library

Discuss
Answer: (c).By the CLR, which loads the metadata into memory and compiles the IL code into native code using a just-in-time compiler Explanation:.NET assemblies are executed by the CLR, which loads the metadata into memory and compiles the IL code into native code using a just-in-time compiler.
Q13.
What services does the .NET class library offer to .NET programs?

a.

User-interface services, networking, file I/O, string management, and more

b.

Virtual machine services, metadata management, and more

c.

Assembly management, native code compilation, and more

d.

Class hierarchy management, method invocation, and more

Discuss
Answer: (a).User-interface services, networking, file I/O, string management, and more Explanation:The .NET class library offers services such as user-interface services, networking, file I/O, string management, and more to .NET programs.
Q14.
What is managed code?

a.

Code that is verified by the CLR in runtime for security, type safety, and memory usage

b.

Code that is executed outside of the .NET Framework

c.

Code that is executed only in the class library

d.

Code that is compiled directly to native code

Discuss
Answer: (a).Code that is verified by the CLR in runtime for security, type safety, and memory usage Explanation:Managed code is any code that is verified by the CLR in runtime for security, type safety, and memory usage.
Q15.
What are the two basic .NET elements that make up managed code?

a.

MSIL code and metadata

b.

Native code and metadata

c.

Common language runtime and metadata

d.

.NET Framework and class hierarchy

Discuss
Answer: (a).MSIL code and metadata Explanation:Managed code consists of the two basic .NET elements: MSIL code and metadata.
Q16.
What is metadata in managed code?

a.

A special data block that stores data type information describing the various objects used in the assembly

b.

A set of instructions that are compiled to native code

c.

A virtual machine inside which .NET programs are safely executed

d.

An environment that loads and verifies .NET assemblies

Discuss
Answer: (a).A special data block that stores data type information describing the various objects used in the assembly Explanation:Metadata is a special data block that stores data type information describing the various objects used in the assembly.
Q17.
How does the CLR validate operations performed by the IL code in managed code?

a.

By using the information from the metadata about class definitions, methods, and parameters they receive, and the types of every local variable in each method

b.

By loading a pointer into memory and calculating the specific offset that needs to be accessed

c.

By executing the code directly in the .NET Framework

d.

By using the class hierarchy to validate the code

Discuss
Answer: (a).By using the information from the metadata about class definitions, methods, and parameters they receive, and the types of every local variable in each method Explanation:The CLR validates operations performed by the IL code by using the information from the metadata about class definitions, methods, and parameters they receive, and the types of every local variable in each method.
Q18.
Can the CLR easily check the size of an array and raise an exception if the index is out of bounds in managed code?

a.

Yes

b.

No

c.

May be Yes or No

d.

Can't say

Discuss
Answer: (a).Yes Explanation:When an assembly that contains managed code accesses an array item, the CLR can easily check the size of the array and simply raise an exception if the index is out of bounds.
Q19.
Which programming language was designed from the ground up as the "native" .NET language?

a.

C++

b.

Java

c.

C#

d.

Visual Basic .NET

Discuss
Answer: (c).C# Explanation:C# was designed from the ground up as the "native" .NET language.

C#

b.

Visual Basic .NET

c.

Managed C++

d.

J#

Discuss
Answer: (a).C# Explanation:C# is similar to C++ in syntax but functionally more similar to Java.
