Cevabı ve açıklamayı göster

Cevap

Disabling NetBIOS over TCP/IP matches with blocking LLMNR/NBT-NS spoofing; Implementing LAPS matches with mitigating lateral movement from reused local admin credentials; Enforcing Application Allowlisting matches with preventing execution of untrusted binaries; Configuring Screensaver Lock Timeout matches with preventing unauthorized session access to unattended devices.
Each security control targets a specific workstation vulnerability: disabling NetBIOS prevents broadcast name resolution spoofing; LAPS prevents credential reuse and lateral movement; AppLocker restricts binary execution to trusted software; screensaver timeout protects open physical sessions on idle machines.

Adım Adım Çözüm

1
Analyze the purpose of network protocol hardening controls
Disabling NetBIOS over TCP/IP eliminates unauthenticated broadcast name resolution traffic, neutralizing NBT-NS/LLMNR spoofing vectors.
Legacy protocols broadcast requests across the local subnet, which malicious actors on the segment can easily intercept.
2
Analyze local account privilege management solutions
LAPS ensures unique, randomized passwords for local administrator accounts on every endpoint.
If local administrator passwords are standard across machines, compromising one system leads to lateral movement across the entire network.
3
Analyze software execution restriction policies
AppLocker enforce allowlisting rules to block unauthorized executables, installers, and scripts.
Allowlisting operates on a default-deny principle, blocking malware or unauthorized software even if the user attempts to launch it.
4
Analyze physical and environmental workstation controls
Screensaver lock policies require user re-authentication after a set interval of system inactivity.
This control mitigates physical security risks when users leave their desks unattended without manually locking their operating system.

Cevabı ve açıklamayı göster

Cevap

The correct repair sequence requires identifying the EFI System Partition using diskpart, assigning it a temporary drive letter, exiting diskpart to access that drive volume, and running the bcdboot command targeting the new drive letter.
On UEFI systems utilizing GPT disks, startup information is contained within an unassigned FAT32 EFI System Partition (ESP). To repair corrupted BCD files manually, a technician must first open `diskpart` to locate and select the ESP volume, assign a temporary drive letter (e.g., `S:`), exit `diskpart`, and then execute `bcdboot C:\Windows /s S: /f UEFI` to write fresh system boot files to the partition.

Adım Adım Çözüm

1
Open diskpart to locate the hidden partition
Identifies the FAT32 volume representing the EFI System Partition (ESP).
On GPT/UEFI systems, boot files are stored on a separate hidden FAT32 partition rather than the main C: drive.
2
Assign a drive letter to the EFI partition
The hidden ESP becomes accessible under a specific drive letter such as S:.
Command-line repair utilities require a reachable drive path to write new boot files.
3
Exit diskpart utility
Returns control to the standard WinRE Command Prompt interface.
File structure operations and bcdboot utility execution must be executed outside of diskpart.
4
Run BCDBoot repair tool
Generates a clean Boot Configuration Data file and installs UEFI boot binaries to the ESP.
The bcdboot command extracts fresh startup files from C:\Windows and initializes the BCD on the target partition.

Cevabı ve açıklamayı göster

Cevap: Boot the system into Safe Mode to uninstall recently updated drivers or disable problematic startup services.; Use System Restore from WinRE Advanced Options to roll back the system state to a restore point created before the update.

Cevap

The correct actions are booting into Safe Mode to uninstall problematic drivers/services and using System Restore from Advanced Options to revert system files to a known working restore point.
Booting into Safe Mode allows the technician to load a minimal set of drivers to disable or uninstall recently added updates causing the boot loop. Additionally, running System Restore from WinRE Advanced Options reverts system settings, drivers, and registry states to a functional state prior to the interrupted update.

Adım Adım Çözüm

1
Analyze the boot failure stage.
The spinning circle indicator confirms the bootloader (BOOTMGR/BCD) has successfully initialized, and the OS is hanging during the driver/service loading phase.
Identifying the exact phase of boot failure prevents executing unnecessary bootloader repair commands.
2
Select non-destructive software isolation steps.
Safe Mode allows targeted removal of problematic software or drivers, while System Restore safely reverts system state to prior configuration.
Both methods address OS-level driver and file corruption without performing destructive disk operations.

A technician is troubleshooting a Windows 10 workstation that enters a continuous reboot loop displaying a stop error (BSOD) immediately after the Windows splash screen appears. The issue began right after a user installed an updated video card driver. The technician boots the system into the Windows Recovery Environment (WinRE). Which of the following is the most appropriate action to take first to resolve the startup failure?

Cevabı ve açıklamayı göster

Cevap: Boot the system into Safe Mode and roll back the display adapter driver using Device Manager.

Cevap

Boot the system into Safe Mode and roll back the display adapter driver using Device Manager.
Because the system crashes during kernel initialization right after a driver update, entering Safe Mode allows Windows to start using generic base drivers. Once logged in under Safe Mode, the technician can access Device Manager and revert the display adapter driver to its previous functional state.

Adım Adım Çözüm

1
Identify the root cause of the startup failure.
The BSOD during startup following a driver update indicates a kernel-level driver incompatibility rather than a damaged boot file or hardware disk failure.
Understanding the timeline (occurring immediately after a driver update) isolates the fault to the updated display driver.
2
Select the appropriate recovery environment option to bypass the faulty driver.
Booting into Safe Mode loads basic display drivers (VGA/GOP) instead of the corrupted third-party graphics driver.
Safe Mode prevents non-essential drivers from loading, allowing Windows to boot successfully into a basic desktop state.
3
Remediate the driver issue.
Device Manager is opened to select the graphics card properties and execute 'Roll Back Driver'.
Rolling back reinstates the previously working driver version and resolves the boot loop.

Cevap: Execute sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows to verify and repair system files in the offline installation.; Use bcdedit /set {default} safeboot minimal to force the system to launch in Safe Mode on the next startup.

Cevap

The correct troubleshooting actions are executing the System File Checker command with offline directory parameters to replace corrupted files and configuring BCDedit to force the workstation into Safe Mode to isolate and remove the faulty driver.
When Windows fails during the driver loading phase, running System File Checker with offline flags (/offbootdir and /offwindir) allows WinRE to replace damaged binaries. Concurrently, setting the safeboot minimal flag via BCDedit forces Windows into Safe Mode on the next reboot, which bypasses non-essential third-party drivers and allows the technician to log in and uninstall the offending update.

Adım Adım Çözüm

1
Identify the cause of the boot failure.
The failure occurs during driver initialization after a driver update, pointing to corrupt system files or a third-party driver conflict.
Isolating whether the boot failure is caused by boot loader corruption versus driver/system file corruption dictates the appropriate repair commands.
2
