Q81.
Why is it important for a reverser to have a good understanding of operating systems?

a.

Because operating systems are a key element in a computer.

b.

Because reversing techniques revolve around the operating system.

c.

Both a and b

d.

None of the above.

Discuss
Answer: (c).Both a and b Explanation:Operating systems are a key element in a computer, and that many reversing techniques revolve around the operating system.
Q82.
What is the connection between operating systems and reverse-engineering techniques?

a.

Operating systems serve as a gatekeeper that controls the link between applications and the outside world.

b.

Operating systems are the subject of reverse-engineering techniques.

c.

Both a and b.

d.

None of the above.

Discuss
Answer: (a).Operating systems serve as a gatekeeper that controls the link between applications and the outside world. Explanation:The operating system serves as a gatekeeper that controls the link between applications and the outside world.
Q83.
What is system-level reversing?

a.

Reversing the program code to extract design concepts and algorithms.

b.

Running various tools on the program to obtain information about the target program being investigated.

c.

Understanding software development, the CPU, and the operating system to comprehend a program.

d.

None of the above.

Discuss
Answer: (b).Running various tools on the program to obtain information about the target program being investigated. Explanation:System-level reversing involves running various tools on the program and utilizing various operating system services to obtain information, inspect program executables, track program input and output, and so forth.
Q84.
Where does most of the information come from in system-level reversing?

a.

The program code.

b.

The operating system.

c.

The software developer.

d.

The CPU.

Discuss
Answer: (b).The operating system. Explanation:Most of the information in system-level reversing comes from the operating system, because every interaction that a program has with the outside world must go through the operating system.
Q85.
What is code-level reversing?

a.

Reversing the program code to extract design concepts and algorithms.

b.

Running various tools on the program to obtain information about the target program being investigated.

c.

Understanding software development, the CPU, and the operating system to comprehend a program.

d.

None of the above.

Discuss
Answer: (a).Reversing the program code to extract design concepts and algorithms. Explanation:Code-level reversing involves extracting design concepts and algorithms from a program binary.
Q86.
Why is code-level reversing a complex process?

a.

Because the program code is always poorly written and improperly documented.

b.

Because software can be highly complex and even well-written source code can be difficult to comprehend.

c.

Because code-level reversing requires a mastery of operating systems.

d.

Because code-level reversing requires a solid understanding of high-level programming constructs.

Discuss
Answer: (b).Because software can be highly complex and even well-written source code can be difficult to comprehend. Explanation:Software can be highly complex, and even those with access to a program’s well-written and properly-documented source code are often amazed at how difficult it can be to comprehend.
Q87.
What is required to perform effective code-level reversing?

a.

Knowledge of operating systems.

b.

Knowledge of software development, the CPU, and the operating system.

c.

Knowledge of high-level programming constructs.

d.

None of the above.

Discuss
Answer: (b).Knowledge of software development, the CPU, and the operating system. Explanation:To perform effective code-level reversing, one needs knowledge of software development, the CPU, and the operating system.
Q88.
Why do reversers need to understand operating systems?

a.

To monitor networking activity

b.

To track program input and output

c.

To obtain a wealth of information about the target program

d.

To expose a program's use of operating system objects

Discuss
Answer: (c).To obtain a wealth of information about the target program Explanation:Reversers must understand operating systems because they can be used during reversing sessions to obtain a wealth of information about the target program being investigated.
Q89.
What kind of tools can expose a program's use of operating system objects?

a.

System-monitoring tools

b.

Code-level reversing tools

c.

Network-monitoring tools

d.

File-access monitoring tools

Discuss
Answer: (a).System-monitoring tools Explanation:There are tools that expose a program’s use of operating system objects such as mutexes, pipes, events, and so forth. Many of these tools are system-monitoring tools.
Q90.
What are disassemblers?

a.

Programs that generate executable binary files

b.

Programs that take a program’s executable binary as input and generate textual files that contain the assembly language code

c.

Programs that allow software developers to observe their program while it is running

d.

Programs that monitor networking activity, file accesses, registry access, and so on

Discuss
Answer: (b).Programs that take a program’s executable binary as input and generate textual files that contain the assembly language code Explanation:Disassemblers are programs that take a program’s executable binary as input and generate textual files that contain the assembly language code for the entire program or parts of it.
