Cevap

The correct order of operations is to first enter WinRE Command Prompt, then query installed third-party drivers using DISM to locate the driver's published INF name, next remove the specific driver package via DISM remove-driver, and finally restart the computer to verify standard startup.
When a newly updated or corrupted driver causes a recurring early-boot Stop Screen (BSOD), the technician must perform offline driver servicing. The process starts by booting into WinRE Command Prompt. The technician must first enumerate the offline driver store using DISM to locate the specific Published Name assigned to the driver (e.g., oem12.inf). Once identified, DISM is used to remove that specific driver package from the offline image. Finally, rebooting the system confirms that Windows can initialize successfully without triggering the crash.

Adım Adım Çözüm

1
Access the Windows Recovery Environment (WinRE) Command Prompt.
Obtains an offline command-line environment targeting the unbootable C: drive.
Offline servicing is required because active driver files cannot be modified or uninstalled while Windows is running or continuously crashing.
2
Run dism /image:C:\ /get-drivers.
Generates a complete list of third-party drivers along with their assigned Published Names (e.g., oem12.inf).
DISM requires the specific published INF package name to targetedly remove a driver from an offline image.
3
Run dism /image:C:\ /remove-driver /driver:oem12.inf.
Uninstalls the specified driver package from the offline system image.
Removing the corrupted driver prevents Windows from attempting to initialize it during the early boot phase.
4
Reboot the workstation normally.
Windows completes initialization without crashing.
Verifies that eliminating the corrupted third-party driver successfully restores normal OS startup.

The technician suspects a memory leak from a background service combined with virtual memory exhaustion due to improper pagefile settings. Arrange the following diagnostic and remediation actions in the correct chronological order to systematically isolate the faulting process, reconfigure virtual memory, and confirm resolution.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct troubleshooting sequence is: 1) Open Task Manager to inspect physical RAM usage versus Commit Charge, 2) Launch Resource Monitor and sort processes by Commit (KB) to isolate the leaking service, 3) Configure virtual memory to automatic management in sysdm.cpl, 4) Disable the leaking third-party service via System Configuration (msconfig), and 5) Restart the system and verify stability using Reliability Monitor (perfmon /rel).
Systematic troubleshooting of Windows performance and application crashes requires progressing from macro-level metric assessment (Task Manager commit charge) to micro-level process isolation (Resource Monitor commit sorting), system resource reconfiguration (virtual memory pagefile adjustment in sysdm.cpl), root cause remediation (disabling the offending service in MSConfig), and post-fix validation (Reliability Monitor).

Adım Adım Çözüm

1
Examine overall system commit metrics in Task Manager.
Identified whether total memory allocation demands exceed physical RAM limits.
Task Manager provides immediate macro-level metrics showing if physical RAM is exhausted and if the system commit charge is approaching the commit limit.
2
Pinpoint the specific process consuming excessive memory in Resource Monitor.
Isolated the exact third-party executable responsible for the memory leak.
Resource Monitor breaks down private working set memory and commit charge per process, exposing background memory leaks.
3
Adjust virtual memory pagefile configuration in Advanced System Settings (sysdm.cpl).
Eliminated artificial pagefile size restrictions.
Enabling automatic pagefile management prevents Windows from abruptly crashing applications due to fixed paging file limits.
4
Prevent the faulty background service from launching on boot using msconfig.
Stopped the offending service from executing on system startup.
Disabling non-essential third-party services in System Configuration stops the memory leak at the root cause.
5

Cevap

The correct sequence is: 1) Isolate the infected workstation from the network, 2) Disable System Restore in Windows, 3) Update anti-malware signatures and perform full system remediation scans, and 4) Re-enable System Restore and create a clean restore point.
The standard CompTIA 7-step malware removal process strictly follows this sequence: 1. Identify malware symptoms, 2. Isolate the infected system, 3. Disable System Restore, 4. Remediate infected systems, 5. Schedule scans and run updates, 6. Enable System Restore and create a restore point, and 7. Educate the end user. Disconnecting network access comes first among these choices to contain the threat, followed by disabling restore points, executing anti-malware scans/remediation, and finally re-enabling System Restore once cleanliness is assured.

Adım Adım Çözüm

1
Isolate the system
The infected endpoint is disconnected from wireless and wired network connections.
Prevents the malware from spreading to other systems on the network or communicating with remote command-and-control servers.
2
Disable System Restore
System Restore is turned off and existing restore points containing infected files are cleared.
Ensures that malware cannot be restored inadvertently from an infected restore point later.
3
Remediate infected systems
Anti-malware software is updated with current definition files and full system scans are run.
Identifies and removes active malware threats and associated infected files.
4
Re-enable System Restore
System Restore is re-enabled and a new, verified clean system restore point is created.

CompTIA 7-Step Malware Remediation Procedure
Soru 359Soru

A Windows 11 workstation equipped with UEFI firmware fails to start, displaying an error stating that the Boot Configuration Data (BCD) file is missing or corrupted. Automatic Repair is unable to resolve the issue. A system administrator boots the computer using Windows installation media to manually rebuild the EFI System Partition (ESP) boot loader from the Command Prompt. Place the technician's administrative steps in the correct chronological order from first to last.

Cevabı ve açıklamayı göster

Cevap

The correct sequence begins with booting into the WinRE Command Prompt via installation media, using diskpart to identify and assign a drive letter to the hidden EFI System Partition, formatting that partition as FAT32, executing the bcdboot command to reconstruct the EFI boot store, and finally rebooting the workstation to confirm normal startup.
The correct order follows the standard procedure for repairing corrupted UEFI boot structures: first boot into an offline command shell, mounting/lettering the hidden EFI partition, wiping existing corrupt boot headers with a FAT32 format, writing new boot files with bcdboot, and rebooting to complete testing.

Adım Adım Çözüm

1
Boot from Windows 11 installation media and select 'Repair your computer' to open the WinRE Command Prompt.
Obtained offline administrative CLI access to the unbootable workstation.
System partition modification and offline BCD repairs require an unmounted, offline recovery environment.
2
Launch Diskpart, select the disk and EFI System Partition, and run 'assign letter=S'.
The hidden FAT32 EFI System Partition becomes accessible via drive letter S:.
UEFI bootloader recovery commands require a target drive letter path to apply new boot files.
3
Execute 'format S: /FS:FAT32' within Diskpart or Command Prompt.
The target partition is clean-formatted with the mandatory FAT32 file system.
Clearing corrupted file systems and damaged boot blocks ensures clean deployment of replacement boot infrastructure.
4
Run 'bcdboot C:\Windows /s S: /f UEFI'.
Fresh UEFI boot files and BCD entries are copied from C:\Windows into S:.
The bcdboot tool initializes the EFI System Partition with essential boot files and BCD configuration mandatory for UEFI startup.
5
Remove installation media, exit the command prompt, and restart the system.
The workstation successfully boots into the Windows operating system.
Rebooting verifies that the UEFI firmware correctly detects the restored EFI System Partition boot sequence.
