answer is highlighted, and a detailed rationale is provided below.
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><strong>Answer & Rationale</strong></summary>
<strong>Correct Answer: C. Safe Mode</strong><br> • <strong>Safe
Mode:</strong> 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:4].<br> • <strong>Enable Boot Logging:</strong> Incorrect. This
creates a log file (ntbtlog.txt) of the boot process but does not change the
environment to a minimal state.<br> • <strong>Last Known Good
Configuration:</strong> Incorrect. This reverts registry settings from the last
successful logon, but this feature is not available in modern versions of Windows
10/11[citation:4].<br> • <strong>Disable Driver Signature Enforcement:</strong>
Incorrect. This allows the installation of drivers without a digital signature but does
,not create a secure, minimal environment specifically designed for troubleshooting.

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><strong>Answer & Rationale</strong></summary>
<strong>Correct Answer: A. diskpart</strong><br> • <strong>diskpart:</strong>
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:4].<br> •
<strong>chkdsk:</strong> Incorrect. This checks the file system for logical or
physical errors but does not manage partition structures.<br> • <strong>system file
checker (SFC):</strong> Incorrect. 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><strong>Answer & Rationale</strong></summary>
<strong>Correct Answer: A. top</strong><br> • <strong>top:</strong> Correct.
The 'top' command provides a real-time, dynamic view of running processes in a
terminal, continuously updating CPU, memory, and process usage[citation:4].<br>
• <strong>ps -ef:</strong> Incorrect. This command shows a snapshot of processes
at the moment the command is run; it does not update in real-time.<br> •
<strong>killall:</strong> Incorrect. This command terminates processes by name;
it is a management tool, not a monitoring tool.<br> • <strong>dmesg:</strong>
Incorrect. This command displays kernel ring buffer messages (hardware events),
not general process resource usage. </details>
,4. Which Windows feature allows a user to take a desk, walk to a meeting, and
have their applications and documents follow them seamlessly without logging
off?
A. Remote Desktop Protocol (RDP)
B. Virtual Private Network (VPN)
C. DirectAccess
D. Work Folders
<details> <summary><strong>Answer & Rationale</strong></summary>
<strong>Correct Answer: C. DirectAccess</strong><br> •
<strong>DirectAccess:</strong> Correct. DirectAccess provides seamless, always-
on connectivity without requiring the user to initiate a connection. It maintains
session state as the user moves between network segments, effectively allowing
their "applications and documents to follow them" without logging off and on
again.<br> • <strong>Remote Desktop Protocol (RDP):</strong> Incorrect. RDP
allows a user to control a remote computer, but it does not seamlessly transfer the
local session state to another physical location.<br> • <strong>Work
Folders:</strong> Incorrect. This allows file synchronization but does not preserve
open application states or documents.<br> • <strong>Virtual Private Network
(VPN):</strong> Incorrect. VPN secures network traffic over the internet but does
not automatically transfer application state between physical locations. </details>
5. A technician needs to clear the DNS cache on a local Windows workstation
to resolve a website connectivity issue. Which command-line tool will
accomplish this?
A. ipconfig /release
B. ipconfig /renew
C. ipconfig /flushdns
D. ipconfig /registerdns
<details> <summary><strong>Answer & Rationale</strong></summary>
<strong>Correct Answer: C. ipconfig /flushdns</strong><br> • <strong>ipconfig
/flushdns:</strong> Correct. This command purges the local DNS resolver cache.
If a website's IP address changed recently, the old entry in the cache would cause a
connection failure; flushing forces the PC to query the DNS server
again[citation:4].<br> • <strong>ipconfig /release:</strong> Incorrect. This
releases the current DHCP IP address configuration, disconnecting the PC from the
network.<br> • <strong>ipconfig /renew:</strong> Incorrect. This requests a new
, IP address from the DHCP server.<br> • <strong>ipconfig /registerdns:</strong>
Incorrect. This refreshes DHCP leases and registers the computer's DNS names
with the DNS server (used for publishing, not resolving). </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><strong>Answer & Rationale</strong></summary>
<strong>Correct Answer: A. chmod +x script.sh</strong><br> • <strong>chmod
+x script.sh:</strong> Correct. The 'chmod' (change mode) command with the '+x'
flag adds execute permissions to the file for the user, group, and
others[citation:4].<br> • <strong>chmod 644 script.sh:</strong> Incorrect. This
sets read/write for the owner and read-only for everyone else, but it does not
include the execute bit.<br> • <strong>chown root script.sh:</strong> Incorrect.
This changes the owner to 'root', which would likely make the permissions error
worse for a standard user. </details>
7. Which file system is specifically designed for Linux and supports
journaling, permissions, and symbolic links by default?
A. NTFS
B. ext4
C. APFS
D. exFAT
<details> <summary><strong>Answer & Rationale</strong></summary>
<strong>Correct Answer: B. ext4</strong><br> • <strong>ext4:</strong> Correct.
The Fourth Extended File System (ext4) is the default file system for many Linux
distributions. It is a journaling file system, meaning it tracks changes not yet
committed to the disk to prevent corruption[citation:4].<br> •
<strong>NTFS:</strong> Incorrect. NTFS is the default for Windows. Linux can
read/write to NTFS, but it is not "designed for Linux."<br> •
<strong>APFS:</strong> Incorrect. Apple File System is designed for macOS,
iOS, and other Apple devices.<br> • <strong>exFAT:</strong> Incorrect. Extended
File Allocation Table (exFAT) is a cross-platform file system designed for flash
drives (no journaling), optimized for large files. </details>
