Q41.
What are the two types of debuggers in modern operating systems?

a.

User-mode debuggers and kernel-mode debuggers

b.

Assembly language debuggers and high-level language debuggers

c.

Static analysis tools and dynamic analysis tools

d.

Disassemblers and decompilers

Discuss
Answer: (a).User-mode debuggers and kernel-mode debuggers Explanation:Modern operating systems have two different types of debuggers: user-mode debuggers and kernel-mode debuggers.
Q42.
What is the primary use of user-mode debuggers?

a.

Debugging operating system code

b.

Debugging kernel mode applications

c.

Debugging regular user-mode applications

d.

Reverse engineering software

Discuss
Answer: (c).Debugging regular user-mode applications Explanation:User-mode debuggers are typically used by software developers and run as normal applications in user mode, and they can only be used for debugging regular user-mode applications.
Q43.
What is the main advantage of kernel-mode debuggers over user-mode debuggers?

a.

They are easier to use

b.

They allow unlimited control of the target system

c.

They have a more powerful disassembler

d.

They can be used to reverse engineer software

Discuss
Answer: (b).They allow unlimited control of the target system Explanation:Kernel-mode debuggers are far more powerful than user-mode debuggers because they allow unlimited control of the target system and provide a full view of everything happening on the system, regardless of whether it is happening inside application code or inside operating system code.
Q44.
What type of debugger is typically used by software developers?

a.

User-mode debugger

b.

Kernel-mode debugger

c.

Assembly language debugger

d.

High-level language debugger

Discuss
Answer: (a).User-mode debugger Explanation:User-mode debuggers are typically used by software developers.
Q45.
What is the advantage of debuggers that contain powerful disassemblers?

a.

They provide a highly readable and detailed representation of the code

b.

They allow unlimited control of the target system

c.

They can be used to reverse engineer software

d.

They have a more powerful memory dump view

Discuss
Answer: (a).They provide a highly readable and detailed representation of the code Explanation:Debuggers that contain powerful disassemblers are usually the best reversing tools you’ll find because they provide a highly readable and detailed representation of the code, and you can conveniently step through it and see what the code does at every step.
Q46.
What are user-mode debuggers?

a.

Debuggers used by software developers

b.

Debuggers that provide unlimited control of the target system

c.

Debuggers that run in kernel mode

d.

Debuggers that attach to another process and can take full control of it

Discuss
Answer: (d).Debuggers that attach to another process and can take full control of it Explanation:User-mode debuggers are conventional applications that attach to another process (the debugee) and can take full control of it.
Q47.
What is the advantage of user-mode debuggers?

a.

They provide unlimited control of the target system

b.

They can view kernel-mode code within a process

c.

They are easy to set up and use

d.

They can debug a program before execution reaches the main executable's entry point

Discuss
Answer: (c).They are easy to set up and use Explanation:The advantage of user-mode debuggers is that they are very easy to set up and use.
Q48.
What is the downside of user-mode debuggers?

a.

They can only view a single process

b.

They can only view kernel-mode code within a process

c.

They are difficult to set up and use

d.

They cannot debug a program before execution reaches the main executable's entry point

Discuss
Answer: (a).They can only view a single process Explanation:The downside of user-mode debuggers is that they can only view a single process.
Q49.
When might it be difficult to know which process runs the code you're interested in?

a.

When there are several interconnected processes

b.

When the product being debugged has its own kernel-mode components

c.

When the program is implemented purely in user mode

d.

When the debugger is unable to debug a program before execution reaches the main executable's entry point

Discuss
Answer: (a).When there are several interconnected processes Explanation:It can be difficult to know which process runs the code you're interested in when there are several processes that are somehow interconnected.
Q50.
When is being restricted to viewing user-mode code a problem?

a.

When the program being debugged has its own kernel-mode components

b.

When the debugger is unable to debug a program before execution reaches the main executable's entry point

c.

When the program is implemented purely in user mode

d.

When there are several interconnected processes

Discuss
Answer: (a).When the program being debugged has its own kernel-mode components Explanation:Being restricted to viewing user-mode code is usually not a problem unless the program being debugged has its own kernel-mode components.
