Q31.
What is ILDasm?

a.

A disassembler for the IA-32 architecture

b.

A disassembler for ELF file format

c.

A disassembler for Microsoft Intermediate Language (MSIL)

d.

A debugger for .NET reversing

Discuss
Answer: (c).A disassembler for Microsoft Intermediate Language (MSIL) Explanation:ILDasm is a disassembler for the Microsoft Intermediate Language (MSIL), which is the low-level assembly language used in .NET programs.
Q32.
What is the use of ILDasm in .NET reversing?

a.

To view classes and their internal members

b.

To view disassembled listing of functions

c.

To view IA-32 assembly language

d.

Both a and b

Discuss
Answer: (d).Both a and b Explanation:ILDasm is a fundamental tool for .NET reversing and is used to view classes and their internal members, as well as a disassembled listing for one of the functions.
Q33.
What is the difference between the assembly language used in IA-32 architecture and the MSIL?

a.

There is no difference between them

b.

The MSIL is a high-level assembly language, while the IA-32 assembly language is low-level

c.

The IA-32 assembly language is used in .NET programs, while the MSIL is used in other programs

d.

The MSIL is used in .NET programs, while the IA-32 assembly language is used in other programs

Discuss
Answer: (b).The MSIL is a high-level assembly language, while the IA-32 assembly language is low-level Explanation:The MSIL is the low-level assembly language used in .NET programs, but it is a high-level assembly language compared to the IA-32 assembly language that has been described so far.
Q34.
What is the primary purpose of debuggers?

a.

To assist software developers with locating and correcting errors in their programs

b.

To assist software developers with writing new code

c.

To assist software developers with testing their programs

d.

To assist software developers with deploying their programs

Discuss
Answer: (a).To assist software developers with locating and correcting errors in their programs Explanation:Debuggers are primarily designed to help software developers with locating and correcting errors in their programs.
Q35.
How can debuggers be used as reversing tools?

a.

By providing a disassembled view of the currently running function and allowing the user to step through the disassembled code

b.

By providing an interpreted view of the currently running function and allowing the user to modify the interpreted code

c.

By providing a visual representation of the program's data structures and allowing the user to modify them

d.

By providing a list of the program's function calls and allowing the user to modify them

Discuss
Answer: (a).By providing a disassembled view of the currently running function and allowing the user to step through the disassembled code Explanation:Debuggers can be used as reversing tools by providing a disassembled view of the currently running function and allowing the user to step through the disassembled code to understand what the program does at every line.
Q36.
Why is a powerful disassembler a mandatory feature in a good reversing debugger?

a.

Because it allows the user to view the code clearly, with cross-references that reveal which branch goes where and where a certain instruction is called from

b.

Because it allows the user to modify the code of the program being debugged

c.

Because it allows the user to view the program's data structures in a clear and organized manner

d.

Because it allows the user to view the program's memory dump

Discuss
Answer: (a).Because it allows the user to view the code clearly, with cross-references that reveal which branch goes where and where a certain instruction is called from Explanation:A powerful disassembler is a mandatory feature in a good reversing debugger because it allows the user to view the code clearly, with cross-references that reveal which branch goes where and where a certain instruction is called from.
Q37.
What are software and hardware breakpoints?

a.

Features that allow the debugger to pause program execution and transfer control to the debugger when a certain instruction is reached during execution

b.

Features that allow the debugger to modify the code of the program being debugged

c.

Features that allow the debugger to view the program's memory dump

d.

Features that allow the debugger to view the program's data structures in a clear and organized manner

Discuss
Answer: (a).Features that allow the debugger to pause program execution and transfer control to the debugger when a certain instruction is reached during execution Explanation:Software and hardware breakpoints are features that allow the debugger to pause program execution and transfer control to the debugger when a certain instruction is reached during execution.
Q38.
Why is a powerful disassembler important in a good reversing debugger?

a.

To view the code clearly, with cross-references that reveal which branch goes where and where a certain instruction is called from

b.

To control the data/code recognition heuristics manually

c.

To identify code/data ambiguities

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:A powerful disassembler is important in a good reversing debugger to view the code clearly, with cross-references that reveal which branch goes where and where a certain instruction is called from, to control the data/code recognition heuristics manually, and to identify code/data ambiguities.
Q39.
Why are hardware breakpoints especially powerful for reversers?

a.

Because they can greatly simplify the process of mapping and deciphering data structures in a program

b.

Because they can expose the relevant code areas in the program that are responsible for manipulating the data structure in question

c.

Because they can be placed on specific areas of interest in a data structure

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Hardware breakpoints are especially powerful for reversers because they can greatly simplify the process of mapping and deciphering data structures in a program, they can expose the relevant code areas in the program that are responsible for manipulating the data structure in question, and they can be placed on specific areas of interest in a data structure.
Q40.
What are the key features required for a good reversing debugger?

a.

Powerful disassembler, software and hardware breakpoints, view of registers and memory, and process information

b.

Powerful compiler, optimization techniques, support for multiple languages, and code analysis tools

c.

User-friendly interface, code completion, debugging support for mobile devices, and cloud integration

d.

None of the above

Discuss
Answer: (a).Powerful disassembler, software and hardware breakpoints, view of registers and memory, and process information Explanation:The key features required for a good reversing debugger are a powerful disassembler, software and hardware breakpoints, view of registers and memory, and process information.
