220-1202 Operating Systems — 20 Questions

Question 1

A technician is preparing a Windows 11 workstation to run an application that requires hardware virtualization support. The workstation has a compatible CPU, but the application reports that virtualization is not enabled. The technician needs to enable the necessary firmware settings. Which two actions should the technician take? (Choose two.)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Verify that the CPU supports virtualization and that it is not disabled by policy.. Enabling hardware virtualization requires both turning on the CPU virtualization extension in UEFI/BIOS and ensuring the CPU supports it and that no policy blocks it. The firmware setting is the direct control, while verifying support and policy prevents wasted effort if the feature cannot be activated. Other options either disable unrelated features or address different subsystems.

Answer

Enable Data Execution Prevention (DEP) in Windows.

Answer

Disable Hyper-V in Windows Features.

Answer

Install the latest chipset drivers from the motherboard vendor.

Question 2

A user reports that their Windows 10 desktop is running very slowly, and they see frequent hard drive activity even when no applications are open. The computer has 4 GB of RAM and a traditional hard disk drive. Which Windows tool should you use to determine whether the system is using the page file excessively due to insufficient RAM?

Accepted Answer

Performance Monitor. Performance Monitor is the correct tool because it can track specific counters like Memory\Pages/sec and Paging File\% Usage, which directly measure page file activity. These counters reveal whether the system is thrashing due to low RAM. Other tools either lack the necessary detail or serve different purposes entirely.

Answer

Task Manager > Performance tab

Answer

Device Manager

Answer

Resource Monitor

Question 3

A user reports that their Windows 11 laptop's battery drains quickly and the fan runs constantly, even when idle. Task Manager shows a process named 'Service Host: SysMain' using high CPU. The user asks if they can disable this service to improve performance. What should you advise?

Accepted Answer

Yes, but only temporarily; disabling SysMain can reduce disk usage if the system has a fast SSD, but it may also affect performance.. The correct advice is that SysMain can be disabled, especially on systems with SSDs, to reduce resource usage, but it may affect performance. It is not essential, nor is it legacy. Disabling it is a valid troubleshooting step if it causes high CPU or disk usage, but the user should understand the trade-offs.

Answer

No, instead you should disable Windows Search to resolve the high CPU usage.

Answer

No, SysMain is essential for system stability and should never be disabled.

Answer

Yes, disable SysMain because it is a legacy service that is not needed on modern systems.

Question 4

A technician is preparing a new Windows 11 installation for a small office. The office uses a local printer shared from a Windows 11 workstation. The technician wants to ensure that other Windows 11 computers on the same network can automatically discover and install the shared printer without manual driver installation. Which Windows feature should the technician enable on the workstation sharing the printer?

Accepted Answer

Printer sharing with additional drivers. To enable automatic driver installation for a shared printer, the technician must share the printer and add additional drivers for the client architectures in use. This makes the drivers available to clients when they connect, so they can install the printer without manual driver steps. Network discovery and file and printer sharing are necessary for connectivity but do not provide the drivers themselves, and Point and Print Restrictions would limit installation.

Answer

Point and Print Restrictions

Answer

Network discovery

Answer

File and printer sharing

Question 5

A user reports that their Windows 11 laptop takes several minutes to reach the desktop after signing in, and the desktop icons and taskbar appear one by one. No error messages are displayed. You open Task Manager and see that disk usage is at 100% for several minutes after logon. Which Windows tool should you use first to identify the specific startup program causing the delay?

Accepted Answer

Task Manager > Startup tab. Task Manager's Startup tab is the built-in tool that specifically lists programs set to run at logon and provides an impact rating based on resource usage. Since the symptom is slow logon with high disk usage, checking this tab lets you quickly identify and disable the offending startup app. Other tools are either too broad or focus on the wrong object.

Answer

System Configuration (msconfig) > Services tab

Answer

Event Viewer > Windows Logs > Application

Answer

Performance Monitor with a Data Collector Set

Question 6

A technician is upgrading a Windows 11 Pro workstation from a SATA SSD to a larger NVMe drive. The user needs to retain installed applications, user profiles, and the existing domain join. Which tool should the technician use to move the installation to the new drive without reinstalling Windows?

Accepted Answer

Third-party drive cloning software, such as Macrium Reflect or Clonezilla. Cloning is the correct migration path because it duplicates the source disk's partitions and boot configuration onto the new NVMe drive, so the installed applications, profiles, and domain membership continue to work. Image-based restore and reset operations either rebuild the layout or strip applications, and Extend Volume cannot populate a blank disk.

Answer

Disk Management's Extend Volume on the new disk after cloning

Answer

Windows System Image Backup (wbadmin) restore to the new disk

Answer

Windows Recovery Environment's Reset this PC with Keep my files

Question 7

A technician is troubleshooting a Windows 10 workstation that fails to boot. The technician suspects a problem with the boot configuration data (BCD). Which two commands can be used to rebuild the BCD? (Choose two.)

Accepted Answer

bootrec /rebuildbcd. The two commands that rebuild the BCD are bootrec /rebuildbcd and bcdboot. bootrec /rebuildbcd scans for Windows installations and rebuilds the BCD store, while bcdboot creates or repairs the BCD and boot files from a specified Windows directory. The other commands either back up, fix the boot sector, or fix the MBR, but do not rebuild the BCD.

Answer

bootrec /fixboot

Answer

bootrec /fixmbr

Answer

bcdedit /export

Question 8

A user calls the help desk because their Windows 11 laptop will not boot. The screen displays the message "Bootmgr is missing" immediately after the manufacturer logo. The technician needs to repair the boot configuration data so the system can start normally. Which command should the technician run from the Windows Recovery Environment?

Accepted Answer

bootrec /rebuildbcd. The "Bootmgr is missing" error means the boot manager cannot find a valid Boot Configuration Data entry for the Windows installation. The bootrec /rebuildbcd command scans for Windows installations and rebuilds the BCD store, directly resolving this issue. Other recovery commands address different problems such as MBR corruption, system file damage, or disk errors, and would not restore the missing boot entry.

Answer

bootrec /fixmbr

Answer

chkdsk /f

Answer

sfc /scannow

Question 9

A help desk technician receives a Windows 11 laptop that displays a message that the operating system cannot be found at startup. The drive is detected in firmware, and the technician wants to rebuild the boot configuration without reinstalling Windows. Which command should be run from the Windows Recovery Environment?

Accepted Answer

bootrec /rebuildbcd. The missing operating system message on a detected drive usually means the Boot Configuration Data store lacks a valid entry. Rebuilding it with bootrec /rebuildbcd from the recovery environment re-creates the Windows Boot Manager entry and restores startup without a full reinstall.

Answer

chkdsk C: /f /r

Answer

sfc /scannow

Answer

bootrec /fixmbr

Question 10

An administrator needs to deploy a standardized Windows 11 image to 40 new workstations and must remove the built-in consumer applications while preserving the Start layout and driver set. Which deployment approach best meets these requirements with the least manual effort per machine?

Accepted Answer

Create a Windows system image with DISM and deploy it with an unattend.xml answer file. A DISM-captured image applied with an unattend.xml answer file delivers a consistent, automated deployment. The administrator can remove built-in applications during image preparation, inject drivers, and define the Start layout once, then apply the same image to all 40 workstations with minimal per-machine interaction.

Answer

Install Windows manually on each PC, then run a PowerShell script to remove applications

Answer

Perform an in-place upgrade on each workstation using a mounted ISO

Answer

Use Windows Backup to restore a reference workstation's files to each new PC

Question 11

A technician is configuring a Windows 11 workstation that will be shared by multiple users in a lab. The requirement is that each user's documents and settings remain separate, and that the disk space used by each user's profile is limited to 500 MB. Which Windows feature should the technician use to enforce the storage limit?

Accepted Answer

Disk Quotas. Disk Quotas are the Windows feature designed to limit the amount of disk space individual users can consume on a volume. By enabling quotas on the volume storing user profiles and setting a 500 MB limit per user, the technician ensures each user's profile cannot exceed the specified size. Other options address data redirection, storage pooling, or privilege elevation, none of which enforce per-user storage limits.

Answer

Storage Spaces

Answer

Folder Redirection

Answer

User Account Control

Question 12

A technician is troubleshooting a Windows 10 workstation that frequently becomes unresponsive. The user reports that the system slows down dramatically after a few hours of use, and the technician suspects a memory leak or resource exhaustion. The technician opens Task Manager and switches to the Performance tab. Which two counters should the technician monitor to confirm the suspicion? (Choose two.)

Accepted Answer

Memory usage percentage. Memory usage percentage and available memory are the two counters that directly reflect physical memory consumption and availability. A memory leak causes memory usage to climb and available memory to shrink over time, matching the reported slowdown. CPU utilization, disk queue length, and GPU usage can be affected indirectly but do not confirm memory exhaustion as directly as the memory-specific counters.

Answer

Disk queue length

Answer

CPU utilization

Answer

GPU usage

Question 13

A technician is troubleshooting a Windows 11 desktop that randomly freezes and displays a blue screen with the stop code DRIVER_IRQL_NOT_LESS_OR_EQUAL. The technician suspects a recently updated device driver. Which two tools or artifacts should the technician examine to identify the offending driver? (Choose two.)

Accepted Answer

The memory dump file analyzed with WinDbg. The memory dump analyzed with WinDbg names the faulting module directly, and Driver Verifier forces the misbehaving driver to crash deterministically so it can be identified. Together they move the investigation from a general bug check to a specific driver file that can be updated, rolled back, or removed.

Answer

Reliability Monitor

Answer

Event Viewer's System log

Answer

Performance Monitor's counter logs

Question 14

A technician needs to install a 64-bit application on a Windows 11 system. The application requires .NET Framework 3.5. When the technician tries to enable .NET Framework 3.5 through Windows Features, the installation fails with error 0x800F0906. What is the most likely cause?

Accepted Answer

The system does not have an internet connection to download the required files.. Error 0x800F0906 occurs when Windows cannot download the necessary files to enable .NET Framework 3.5. This is typically due to no internet connection or Windows Update being unavailable. The correct resolution is to use DISM with a source path pointing to the Windows installation media, or to enable the feature while connected to the internet. The other options do not match the error code.

Answer

The user does not have administrative privileges.

Answer

The .NET Framework 3.5 feature is corrupted in the Windows component store.

Answer

The application is not compatible with Windows 11.

Question 15

A user reports that a Ubuntu Linux workstation boots to a command-line prompt instead of the graphical desktop after a recent package update. The technician wants to check which systemd target is currently active and switch to the graphical environment without rebooting. Which sequence of commands should the technician use?

Accepted Answer

systemctl list-units --type=target, then systemctl isolate graphical.target. Listing active targets identifies the current systemd state, and isolating graphical.target transitions the running system into the graphical environment right away. This satisfies the requirement to switch without rebooting, and the default target can be corrected separately if the change needs to survive a restart.

Answer

systemctl get-default, then systemctl set-default graphical.target

Answer

systemctl isolate multi-user.target, then reboot

Answer

systemctl status graphical.target, then systemctl restart gdm

Question 16

A user reports that their Windows 11 laptop display appears very dim even at the highest brightness setting. The technician suspects that the display adapter driver may be causing the issue. Which tool should the technician use to verify the driver version and check for driver errors?

Accepted Answer

Device Manager. Device Manager is the Windows tool that provides a centralized view of hardware devices and their drivers. It allows the technician to check the display adapter's driver version, update it, and see error codes that might explain the dim display. Task Manager, Disk Management, and System Configuration serve different purposes and do not offer driver-level diagnostics for hardware devices.

Answer

Task Manager

Answer

Disk Management

Answer

System Configuration
