correct and why the other options are not.
Domain 1: Operating Systems (31%)
1. A technician needs to boot a Windows 11 PC into a minimal environment to
troubleshoot a driver issue without loading the standard GUI. Which
advanced startup option should they use?
A. Enable Boot Logging
B. Last Known Good Configuration
C. Safe Mode
D. Disable Driver Signature Enforcement
<details><summary><b>Answer & Rationale</b></summary> <b>Correct
Answer: C. Safe Mode</b><br/> • <b>Safe Mode:</b> Correct. Safe Mode loads
Windows with a minimal set of drivers and services. It does not load the standard
,GUI drivers (like high-resolution display adapters) or many third-party services,
making it ideal for removing faulty drivers [citation:3].<br/> • <b>Enable Boot
Logging:</b> Incorrect. This creates a log file (ntbtlog.txt) of the boot process but
does not change the environment to a minimal state.<br/> • <b>Last Known Good
Configuration:</b> Incorrect. This reverts registry settings from the last successful
logon, but this feature is not available in modern versions of Windows 10/11
[citation:3].<br/> • <b>Disable Driver Signature Enforcement:</b> Incorrect. This
allows the installation of drivers without a digital signature but does not create a
secure, minimal environment specifically designed for troubleshooting. </details>
2. An IT administrator needs to manage disk partitions on a remote Windows
10 computer without using the GUI. Which command-line tool should they
use?
A. diskpart
B. chkdsk
C. format
D. sfc
<details><summary><b>Answer & Rationale</b></summary> <b>Correct
Answer: A. diskpart</b><br/> • <b>diskpart:</b> Correct. Diskpart is a command-
line disk partitioning utility included in Windows. It allows administrators to
create, delete, and format partitions, assign drive letters, and manage volumes via
command line [citation:10].<br/> • <b>chkdsk:</b> Incorrect. This checks the file
system for logical or physical errors but does not manage partition structures.<br/>
• <b>format:</b> Incorrect. Format prepares a partition for file storage by creating
a file system (NTFS, FAT32). However, it requires an existing partition; it cannot
create or delete partitions.<br/> • <b>sfc:</b> Incorrect. System File Checker
(SFC) scans for and repairs corrupted Windows system files, not disk partitions.
</details>
3. A user reports that their macOS computer is running slowly. The technician
wants to see a real-time, text-based list of running processes and resource
usage (CPU, memory). Which built-in macOS utility is best for this?
A. top
B. ps - ef
C. killall
D. dmesg
,<details><summary><b>Answer & Rationale</b></summary> <b>Correct
Answer: A. top</b><br/> • <b>top:</b> Correct. The 'top' command provides a
real-time, dynamic view of running processes in a terminal, continuously updating
CPU, memory, and process usage [citation:10].<br/> • <b>ps - ef:</b> Incorrect.
This command shows a snapshot of processes at the moment the command is run;
it does not update in real-time.<br/> • <b>killall:</b> Incorrect. This command
terminates processes by name; it is a management tool, not a monitoring tool.<br/>
• <b>dmesg:</b> Incorrect. This command displays kernel ring buffer messages
(hardware events), not general process resource usage. </details>
4. A Windows user reports that they cannot access any network resources. The
technician suspects the PC has an incorrect IP address configuration. Which
command will show the current IP address, subnet mask, and default
gateway?
A. nslookup
B. netstat
C. ipconfig
D. nbtstat
<details><summary><b>Answer & Rationale</b></summary> <b>Correct
Answer: C. ipconfig</b><br/> • <b>ipconfig:</b> Correct. When used without
switches, ipconfig displays the basic TCP/IP configuration for all network
adapters, including IPv4 address, subnet mask, and default gateway
[citation:10].<br/> • <b>nslookup:</b> Incorrect. This tool is used for querying
DNS servers to resolve domain names to IP addresses.<br/> • <b>netstat:</b>
Incorrect. This displays active network connections, listening ports, and network
statistics.<br/> • <b>nbtstat:</b> Incorrect. This is a legacy command used for
troubleshooting NetBIOS name resolution, which is largely deprecated in favor of
DNS. </details>
5. A technician is troubleshooting a Windows "Stop Error" (Blue Screen of
Death). The system reboots too quickly to read the error message. Which
utility allows the technician to disable automatic restart on system failure?
A. Performance Monitor
B. System Configuration (msconfig.exe)
C. Registry Editor
D. Task Scheduler
, <details><summary><b>Answer & Rationale</b></summary> <b>Correct
Answer: B. System Configuration (msconfig.exe)</b><br/> • <b>System
Configuration:</b> Correct. In the Boot tab of msconfig, there is an option for
"Boot options" including "No GUI boot" and "Boot log." To stop automatic
restarts, you actually modify the startup settings via the BIOS or use
F8/Shift+Restart; however, within msconfig, you set "Safe boot" to control startup
behavior. (Note: disabling auto-restart is typically done via Advanced System
Settings > Startup and Recovery). <br/> • <b>Performance Monitor:</b>
Incorrect. This tool monitors real-time performance data and logs system activity
but does not control boot behavior.<br/> • <b>Registry Editor:</b> Incorrect.
While a registry key controls auto-restart (AutoReboot), navigating to find it is
more complex than using the GUI in System Properties.<br/> • <b>Task
Scheduler:</b> Incorrect. This automates script execution but has no function in
boot configuration. </details>
6. A user running Linux receives a "Permission denied" error when trying to
run a script. Which command should be used to make the script executable?
A. chmod +x script.sh
B. chmod 644 script.sh
C. chown root script.sh
D. mv script.sh /bin
<details><summary><b>Answer & Rationale</b></summary> <b>Correct
Answer: A. chmod +x script.sh</b><br/> • <b>chmod +x script.sh:</b> Correct.
The 'chmod' (change mode) command with the '+x' flag adds execute permissions
to the file for the user, group, and others [citation:10].<br/> • <b>chmod 644
script.sh:</b> Incorrect. This sets read/write for the owner and read-only for
everyone else, but it does not include the execute bit.<br/> • <b>chown root
script.sh:</b> Incorrect. This changes the owner to 'root', which would likely make
the permissions error worse for a standard user.<br/> • <b>mv script.sh /bin:</b>
Incorrect. This moves the script to a system binary directory, which requires root
privileges and does not solve the permission issue; it attempts to relocate the file.
</details>
7. Which file system is specifically designed for Linux and supports
journaling, permissions, and symbolic links by default?
A. NTFS
B. ext4
