Q61.
What is one area where WinDbg surpasses OllyDbg?

a.

GUI-based interface

b.

Integration with the operating system

c.

Support for multiple programming languages

d.

Ability to display register values

Discuss
Answer: (b).Integration with the operating system Explanation:One place where WinDbg is unbeatable and far surpasses OllyDbg is in its integration with the operating system.
Q62.
What type of information can WinDbg extensions provide?

a.

Information on currently active user-mode heaps

b.

Information on security tokens

c.

Information on the PEB and TEB

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:WinDbg extensions can provide a wealth of information on a variety of internal system data structures including currently active user-mode heaps, security tokens, the PEB, and TEB.
Q63.
What is the system loader responsible for?

a.

Loading and initializing program executables

b.

Providing a GUI-based interface for WinDbg

c.

Disassembling code

d.

Providing information on system data structures

Discuss
Answer: (a).Loading and initializing program executables Explanation:The system loader is responsible for loading and initializing program executables.
Q64.
What does WinDbg support that OllyDbg does not?

a.

Debugging at the primary executable's WinMain

b.

Stepping through the earliest phases of process initialization

c.

GUI-based interface

d.

Disassembling code

Discuss
Answer: (b).Stepping through the earliest phases of process initialization Explanation:WinDbg supports stepping through the earliest phases of process initialization, even before statically linked DLLs are initialized. This is different from OllyDbg, where debugging starts at the primary executable's WinMain after all statically linked DLLs are initialized.
Q65.
What type of code is being debugged in the screenshot from WinDbg?

a.

Code from the primary executable's WinMain

b.

Code from statically linked DLLs

c.

Code from the NTDLL loader code that initializes DLLs

d.

Code from the operating system kernel

Discuss
Answer: (c).Code from the NTDLL loader code that initializes DLLs Explanation:The code being debugged in the screenshot from WinDbg is a part of the NTDLL loader code that initializes DLLs while the process is coming.
Q66.
What is the limitation of WinDbg's disassembler?

a.

Inability to scroll backward in the disassembly window

b.

Inability to scroll forward in the disassembly window

c.

Limited number of instructions that can be disassembled

d.

None of the above

Discuss
Answer: (a).Inability to scroll backward in the disassembly window Explanation:WinDbg’s disassembler is quite limited, and has some annoying anomalies (such as the inability to scroll backward in the disassembly window).
Q67.
What is one advantage of WinDbg over OllyDbg?

a.

Better user interface

b.

Better disassembler

c.

Integration with the operating system

d.

None of the above

Discuss
Answer: (c).Integration with the operating system Explanation:Unsurprisingly, one place where WinDbg is unbeatable and far surpasses OllyDbg is in its integration with the operating system.
Q68.
What can WinDbg's extensions provide information on?

a.

Currently active user-mode heaps

b.

Security tokens

c.

The PEB (Process Environment Block) and the TEB (Thread Environment Block)

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:WinDbg has powerful extensions that can provide a wealth of information on a variety of internal system data structures. This includes dumping currently active user-mode heaps, security tokens, the PEB (Process Environment Block) and the TEB (Thread Environment Block), the current state of the system loader (the component responsible for loading and initializing program executables), and so on.
Q69.
What is one way in which WinDbg differs from OllyDbg in terms of debugging?

a.

WinDbg supports stepping through the earliest phases of process initialization

b.

OllyDbg supports stepping through the earliest phases of process initialization

c.

WinDbg and OllyDbg both support stepping through the earliest phases of process initialization

d.

None of the above

Discuss
Answer: (a).WinDbg supports stepping through the earliest phases of process initialization Explanation:Beyond the extensions, WinDbg also supports stepping through the earliest phases of process initialization, even before statically linked DLLs are initialized. This is different from OllyDbg, where debugging starts at the primary executable’s WinMain (this is the .exe file launched by the user), after all statically linked DLLs are initialized.
Q70.
What advantage does OllyDbg have over WinDbg?

a.

Better user interface

b.

Better disassembler

c.

More powerful code analysis capabilities

d.

None of the above

Discuss
Answer: (c).More powerful code analysis capabilities Explanation:Still, for reversing applications that aren’t heavily integrated with the operating systems, OllyDbg has significant advantages. Olly has a far better user interface, has a better disassembler, and provides powerful code analysis capabilities that really make reversing a lot easier.
