GCIA · Question #27

Which of the following is the correct order of loading system files into the main memory of the system, when the computer is running on Microsoft's Windows XP operating system?

The correct answer is D. NTLDR, BOOT.ini, NTDETECT.com, HAL.dll, NTOSKRNL.exe. The Windows XP boot sequence requires NTLDR to run first, then read BOOT.ini, then call NTDETECT.COM to inventory hardware before HAL.dll can abstract that hardware for the kernel, and finally NTOSKRNL.exe loads.

Question

Which of the following is the correct order of loading system files into the main memory of the system, when the computer is running on Microsoft's Windows XP operating system?

Options

  • ANTLDR, BOOT.ini, HAL.dll, NTDETECT.com, NTOSKRNL.exe
  • BBOOT.ini, HAL.dll, NTDETECT.com, NTLDR, NTOSKRNL.exe
  • CNTLDR, BOOT.ini, HAL.dll, NTDETECT.com, NTOSKRNL.exe
  • DNTLDR, BOOT.ini, NTDETECT.com, HAL.dll, NTOSKRNL.exe

Why each option

The Windows XP boot sequence requires NTLDR to run first, then read BOOT.ini, then call NTDETECT.COM to inventory hardware before HAL.dll can abstract that hardware for the kernel, and finally NTOSKRNL.exe loads.

ANTLDR, BOOT.ini, HAL.dll, NTDETECT.com, NTOSKRNL.exe

This sequence loads HAL.dll before NTDETECT.COM, which is incorrect because HAL.dll requires the hardware inventory that NTDETECT.COM produces in order to build its abstraction layer.

BBOOT.ini, HAL.dll, NTDETECT.com, NTLDR, NTOSKRNL.exe

This sequence starts with BOOT.ini before NTLDR, which is impossible - BOOT.ini is a plain text configuration file that has no executable capability and cannot initiate the boot process.

CNTLDR, BOOT.ini, HAL.dll, NTDETECT.com, NTOSKRNL.exe

Like option A, this sequence incorrectly positions HAL.dll ahead of NTDETECT.COM, reversing the required dependency between hardware detection and hardware abstraction.

DNTLDR, BOOT.ini, NTDETECT.com, HAL.dll, NTOSKRNL.exeCorrect

The correct order is NTLDR (bootstrap loader activates), BOOT.ini (NTLDR parses it for OS menu options), NTDETECT.COM (scans and reports installed hardware back to NTLDR), HAL.dll (uses the hardware inventory to abstract physical devices for the kernel), and NTOSKRNL.exe (kernel initializes using the abstracted hardware environment). Hardware detection by NTDETECT.COM is a prerequisite for HAL.dll to function correctly.
