Q241.

What is the ExceptionList member?

The head of the current thread’s exception handler list

A linear list of handlers that are called for every exception

A data structure that manages the hierarchy of exception handlers within a single function

A pointer to the currently active thread-specific data structures

Discuss

Answer: (a).The head of the current thread’s exception handler list Explanation:The ExceptionList member is the head of the current thread’s exception handler list.

Q242.

How does Windows handle user-mode page faults that aren't resolved by the memory manager?

Windows calls into a user-mode exception dispatcher routine called KiUserExceptionDispatcher in NTDLL.DLL

Windows calls into a kernel-mode exception dispatcher routine called KiKernelExceptionDispatcher in KERNEL32.DLL

Windows generates a new thread to handle the exception

Windows terminates the process

Discuss

Answer: (a).Windows calls into a user-mode exception dispatcher routine called KiUserExceptionDispatcher in NTDLL.DLL Explanation:Windows calls into a user-mode exception dispatcher routine called KiUserExceptionDispatcher in NTDLL.DLL to handle user-mode page faults that aren't resolved by the memory manager.

Q243.

What is the purpose of the _EXCEPTION_REGISTRATION_RECORD data structure?

To store the exception handler list

To provide support for nested exception-handling blocks and for multiple blocks within the same function

To manage the hierarchy of exception handlers within a single function

To call the correct exception filter and exception handler based on the current function’s layout

Discuss

Answer: (b).To provide support for nested exception-handling blocks and for multiple blocks within the same function Explanation:The _EXCEPTION_REGISTRATION_RECORD data structure is used to provide support for nested exception-handling blocks and for multiple blocks within the same function.

Q244.

What is the importance of understanding the executable file format?

It provides hints regarding programs and their architectures

It helps in observing and monitoring applications

It helps in deciphering programs

None of the above

Discuss

Answer: (a).It provides hints regarding programs and their architectures Explanation:Understanding the executable file format is crucial because it provides hints regarding programs and their architectures.

Q245.

Why is having a basic understanding of how the system communicates with the outside world helpful?

It helps in observing and monitoring applications

It helps in deciphering programs

It helps in understanding the system's executable file format

All of the above

Discuss

Answer: (a).It helps in observing and monitoring applications Explanation:Having a basic understanding of how the system communicates with the outside world is helpful for effectively observing and monitoring applications using the various system monitoring tools.

Q246.

What is the importance of understanding the basic APIs offered by the operating system?

It helps in observing and monitoring applications

It helps in deciphering programs

It helps in understanding the system's executable file format

All of the above

Discuss

Answer: (b).It helps in deciphering programs Explanation:Understanding the basic APIs offered by the operating system can be helpful in deciphering programs.

Q247.

What is virtual memory?

A layer between the software and the physical memory

Physical memory that is accessed directly by software

An invisible table that manages physical memory

A type of memory that can only be accessed by the operating system

Discuss

Answer: (a).A layer between the software and the physical memory Explanation:Virtual memory is a layer between the software and the physical memory.

Q248.

What is a handle in Windows?

A process-specific numeric identifier

A pointer to the underlying object

An access mask that determines which types of operations can be performed on the object

All of the above

Discuss

Answer: (d).All of the above Explanation:A handle is a process-specific numeric identifier which is essentially an index into the process’s private handle table. Each entry in the handle table contains a pointer to the underlying object, which is how the system associates handles with objects. Along with the object pointer, each handle entry also contains an access mask that determines which types of operations that can be performed on the object using this specific handle.

Q249.

What is the Win32 API?

The actual interface to the Windows NT system.

The layer above the native API in Windows NT.

The graphics-related services in Windows NT.

The high-level interface an application employs to communicate with the OS.

Discuss

Answer: (b).The layer above the native API in Windows NT. Explanation:The Win32 API is a layer above the native API in Windows NT.

Q250.

What is the native API?

A set of functions exported from NTDLL.DLL only

A set of functions exported from NTOSKRNL.EXE only

A set of functions exported from both NTDLL.DLL and NTOSKRNL.EXE

None of the above

Discuss

Answer: (c).A set of functions exported from both NTDLL.DLL and NTOSKRNL.EXE Explanation:The native API is a set of functions exported from both NTDLL.DLL (for user-mode callers) and from NTOSKRNL.EXE (for kernel-mode callers).
