Q1.
Why is reversing important for achieving interoperability?

a.

It helps software developers communicate more effectively with hardware

b.

It allows software developers to bypass using third-party libraries

c.

It provides insight into third-party code beyond what is documented

d.

It enables developers to create their own APIs

Discuss
Answer: (c).It provides insight into third-party code beyond what is documented Explanation:One of the most important applications of reversing is to achieve interoperability. The idea is that by learning reversing techniques, software developers can more efficiently interoperate with third-party code, which is something every software developer does every day. Reversing provides the ultimate insight into the third-party’s code, which takes you beyond the documentation.
Q2.
What is the purpose of dissecting functions in the Windows native API?

a.

To create new APIs

b.

To learn how to reverse engineer software

c.

To understand what each function does and how to use it

d.

To demonstrate the complexity of undocumented APIs

Discuss
Answer: (c).To understand what each function does and how to use it Explanation:The purpose of dissecting functions in the Windows native API is to understand what each function does and how to use it.
Q3.
What is interoperability for a software engineer?

a.

Getting software to cooperate with hardware

b.

Getting software to cooperate with software written by someone else

c.

Creating new software components

d.

Debugging software code

Discuss
Answer: (b).Getting software to cooperate with software written by someone else Explanation:Interoperability for a software engineer means getting the software to cooperate with software written by someone else.
Q4.
What is one of the biggest challenges in large-scale software development?

a.

Getting software to communicate with hardware

b.

Getting software to communicate with other components of the same program

c.

Getting software to communicate with other programs

d.

All of the above

Discuss
Answer: (b).Getting software to communicate with other components of the same program Explanation:Getting software to communicate with other components of the same program, other programs, software libraries, and the operating system can be one of the biggest challenges in large-scale software development.
Q5.
What is a common problem with relying exclusively on vendor-supplied documentation?

a.

The documentation is too detailed

b.

The documentation always mentions every function and parameter

c.

The documentation almost always neglects to mention certain functions, parameters, or entire features

d.

The documentation is written in a foreign language

Discuss
Answer: (c).The documentation almost always neglects to mention certain functions, parameters, or entire features Explanation:Any seasoned software developer knows that relying exclusively on vendor-supplied documentation is rarely a smooth and easy process because the documentation almost always neglects to mention certain functions, parameters, or entire features.
Q6.
What is an example of undocumented APIs in the Windows operating system?

a.

APIs that were kept undocumented to give Microsoft an edge over one software vendor or another

b.

APIs that were kept undocumented to maintain compatibility with other Windows platforms

c.

APIs that were kept undocumented because they were not useful

d.

Both a and b

Discuss
Answer: (d).Both a and b Explanation:The Windows operating system historically contained hundreds of undocumented APIs that were kept undocumented for a variety of reasons, such as to maintain compatibility with other Windows platforms and to give Microsoft an edge over one software vendor or another.
Q7.
When might a software developer use techniques for digging into third-party code on their own?

a.

When they have sufficient documentation

b.

When they have access to the source code of the component with which they’re interfacing

c.

When they are experiencing problems with third-party code and have no choice but to try to solve these problems on their own

d.

All of the above

Discuss
Answer: (c).When they are experiencing problems with third-party code and have no choice but to try to solve these problems on their own Explanation:A software developer might use techniques for digging into third-party code on their own when they are experiencing problems with third-party code and have no choice but to try to solve these problems on their own.
Q8.
What is the first step in dealing with undocumented code?

a.

Reverse engineering the code

b.

Identifying missing functionality

c.

Analyzing executable modules

d.

Dumping import and export directories

Discuss
Answer: (b).Identifying missing functionality Explanation:The first step is to identify missing functionality.
Q9.
How can interfaces between binary modules be observed?

a.

By reverse engineering the code

b.

By identifying missing functionality

c.

By analyzing executable modules

d.

By dumping import and export directories

Discuss
Answer: (d).By dumping import and export directories Explanation:Interfaces between binary modules can be observed by dumping import and export directories.
Q10.
Where are the majority of undocumented user-mode services in Windows implemented?

a.

KERNEL32.DLL

b.

ADVAPI32.DLL

c.

NTDLL.DLL

d.

USER32.DLL

Discuss
Answer: (c).NTDLL.DLL Explanation:The majority of undocumented user-mode services in Windows are implemented in NTDLL.DLL.
