Q41.

What is the purpose of the evaluation stack in .NET?

To store intermediate results during the execution of IL code.

To store the original source code.

To store native code.

None of the above

Discuss

Answer: (a).To store intermediate results during the execution of IL code. Explanation:The evaluation stack is used to store intermediate results during the execution of IL code.

Q42.

What is an activation record in .NET?

A record of all the methods used in a program.

A record of all the classes used in a program.

A data structure used to store information about a method call.

None of the above

Discuss

Answer: (c).A data structure used to store information about a method call. Explanation:The activation record is a data structure used to store information about a method call.

Q43.

What is the function of IL instructions in .NET?

To define the layout of data types in .NET programs.

To compile the original source code to IL code.

To define the basic operations that can be performed on data types.

None of the above

Discuss

Answer: (c).To define the basic operations that can be performed on data types. Explanation:The IL instructions define the basic operations that can be performed on data types.

Q44.

What is the evaluation stack in .NET programs?

It is a stack of 32-bit entries used for managing state information

It is a fixed-size stack used for storing immediate information

It is a virtual stack used by IL code for managing state information

It is a polymorphic stack used for storing different data types

Discuss

Answer: (c).It is a virtual stack used by IL code for managing state information Explanation:The evaluation stack is a virtual stack used by IL code for managing state information in .NET programs. It is not a physical stack and has no meaning during runtime.

Q45.

How do instructions in the IL instruction set deal with different data types?

They require explicit instructions to handle different data types

They use a fixed data type for all operands

They are polymorphic and can handle a variety of data types

They use registers to handle different data types

Discuss

Answer: (c).They are polymorphic and can handle a variety of data types Explanation:Many instructions in the IL instruction set are polymorphic, meaning they can handle different data types and can properly deal with a variety of types.

Q46.

How do IL instructions access their operands?

By using a fixed data type for all operands

By using registers to access operands

By popping a value off of the stack or pushing a value onto it

By explicitly telling instructions which data types to expect

Discuss

Answer: (c).By popping a value off of the stack or pushing a value onto it Explanation:Practically every instruction in IL either pops a value off of the stack or pushes some kind of value back onto it, which is how they access their operands.

Q47.

What are activation records?

Data elements that represent the state of the currently running function

Data elements that represent the state of the currently running program

Data elements that represent the state of the currently running thread

Data elements that represent the state of the currently running object

Discuss

Answer: (a).Data elements that represent the state of the currently running function Explanation:Activation records are data elements that represent the state of the currently running function, containing the parameters passed to the current function along with all the local variables in that function.

Q48.

How are activation records allocated?

On the heap

In the CLR

On the stack

In the activation pool

Discuss

Answer: (c).On the stack Explanation:In most cases, the CLR allocates activation records on the stack, which means that they are essentially the same thing as the stack frames you’ve worked with in native assembly language code.

Q49.

What special instructions does the IL instruction set include for activation records?

Instructions that access the current activation record for function parameters and local variables

Instructions that access the current activation record for global variables

Instructions that access the current activation record for thread-local variables

Instructions that access the current activation record for static variables

Discuss

Answer: (a).Instructions that access the current activation record for function parameters and local variables Explanation:The IL instruction set includes special instructions that access the current activation record for both function parameters and local variables.

Q50.

What is IL?

A type of native executable code

An intermediate language used in .NET programs

A type of programming language

A type of programming paradigm

Discuss

Answer: (b).An intermediate language used in .NET programs Explanation:IL stands for Common Intermediate Language (CIL) or Microsoft Intermediate Language (MSIL), which is an intermediate language used in .NET programs.
