Q11.
When searching for undocumented APIs, what should be the starting point?

a.

Dumping the import and export directories of the modules

b.

Searching the internet for relevant keywords

c.

Reading the program's source code

d.

Contacting the software manufacturer

Discuss
Answer: (a).Dumping the import and export directories of the modules Explanation:The starting point for searching for undocumented APIs is typically dumping the import and export directories of the relevant modules.
Q12.
What should you search for when looking for a specific type of undocumented API?

a.

Relevant keywords

b.

Source code

c.

The software manufacturer's documentation

d.

The module's version number

Discuss
Answer: (a).Relevant keywords Explanation:When looking for a specific type of undocumented API, it is recommended to search the export list of relevant modules for relevant keywords.
Q13.
What is the benefit of finding an executable that calls an undocumented API?

a.

It sheds additional light on what the API does.

b.

It guarantees that the API is properly documented.

c.

It provides a way to modify the API's functionality.

d.

It can be used to bypass security measures.

Discuss
Answer: (a).It sheds additional light on what the API does. Explanation:Finding an executable that calls an undocumented API can provide additional information on what the API does, and how it is used.
Q14.
What is the advantage of using a kernel-mode debugger when looking for code that uses a specific function?

a.

It can install system-wide breakpoints that will get hit whenever any process calls the function.

b.

It is easier to use than a user-mode debugger.

c.

It can modify the behavior of the function.

d.

It can bypass security measures.

Discuss
Answer: (a).It can install system-wide breakpoints that will get hit whenever any process calls the function. Explanation:A kernel-mode debugger can install system-wide breakpoints that will get hit whenever any process calls a specific function, making it easier to locate code that uses that function.
Q15.
What is the generic table API?

a.

A set of functions from the RTL group

b.

A set of functions from the kernel-mode group

c.

A set of functions from the user-mode group

d.

A set of functions from the graphics group

Discuss
Answer: (a).A set of functions from the RTL group Explanation:The generic table API is a set of functions from the RTL group, which contain commonly required services such as string manipulation, data management, and so on.
Q16.
Where is the generic table API implemented?

a.

In NTDLL.DLL

b.

In KERNEL32.DLL

c.

In USER32.DLL

d.

In GDI32.DLL

Discuss
Answer: (a).In NTDLL.DLL Explanation:The generic table API is implemented in NTDLL.DLL.
Q17.
How can you locate relevant functions in NTDLL.DLL?

a.

Look through the list of exported symbols in NTDLL.DLL

b.

Search the Windows Registry

c.

Look through the list of installed Windows updates

d.

Look through the list of installed programs

Discuss
Answer: (a).Look through the list of exported symbols in NTDLL.DLL Explanation:To locate relevant functions in NTDLL.DLL, you can look through the list of exported symbols in NTDLL.DLL.
Q18.
What are some of the functions in the RTL group of APIs?

a.

String manipulation functions, data management functions, etc

b.

Graphics functions, sound functions, etc

c.

File management functions, network functions, etc

d.

Security functions, memory management functions, etc

Discuss
Answer: (a).String manipulation functions, data management functions, etc Explanation:Some of the functions in the RTL group of APIs include string manipulation functions, data management functions, and so on.
Q19.
What is the purpose of searching for binaries that use an undocumented API?

a.

To shed additional light on what the API does

b.

To make it more difficult to use the API in your own code

c.

To prevent other reverse engineers from discovering the API

d.

To identify other undocumented APIs

Discuss
Answer: (a).To shed additional light on what the API does Explanation:The purpose of searching for binaries that use an undocumented API is to shed additional light on what the API does and to provide an example of how the API is used in live code.
Q20.
How can a kernel-mode debugger help in locating code that uses a specific function systemwide?

a.

By installing systemwide breakpoints that get hit whenever any process calls the function

b.

By searching through the Windows Registry for references to the function

c.

By analyzing the source code of all installed programs

d.

By analyzing the memory dumps of all running processes

Discuss
Answer: (a).By installing systemwide breakpoints that get hit whenever any process calls the function Explanation:A kernel-mode debugger can help in locating code that uses a specific function systemwide by installing systemwide breakpoints that get hit whenever any process calls the function.
