Question 1:
You are examining an old CD-ROM intended for both Windows and Linux systems. It uses a filesystem extension to store long filenames that Windows 95 and later versions can recognize. Which CD-ROM filesystem extension is this referring to?
A. Rock Ridge
B. El Torito
C. Joliet
D. HFS
Answer: C
Explanation:
The Joliet filesystem extension was developed by Microsoft for the Windows platform.
• Enables long filenames on CD-ROMs
• Overcomes the limitations of the standard ISO 9660 format
• Designed for compatibility with Windows 95 and later versions
Incorrect
• A. Rock Ridge
○ An extension of ISO 9660 that adds POSIX filesystem semantics
○ Primarily used by Unix and Linux systems
○ Not intended for long filename support on Windows
• B. El Torito
○ An ISO 9660 extension that enables bootable CD-ROMs
○ Unrelated to filename length support
• D. HFS (Hierarchical File System)
○ A filesystem designed for Apple Macintosh computers
○ Not an ISO 9660 CD-ROM filesystem extension
Question 2:
You want to inform all users about a scheduled system maintenance activity. How can you use the wall command to send a message from a file named maintenance_notice.txt to all users?
A. cat maintenance_notice.txt | wall
B. wall < maintenance_notice.txt
C. wall -f maintenance_notice.txt
D. wall --file maintenance_notice.txt
Answer: A
Explanation:
The correct way to send a message stored in a file to all logged-in users using the wall command is to:
• Use cat to read the contents of the file
• Pipe (|) the output to the wall command
This ensures the file’s content is broadcast to all users.
Incorrect
• B. < maintenance_notice.txt wall
○ The < operator is used for input redirection
○ It is not the correct syntax for using wall with a file
• C. wall -f maintenance_notice.txt
○ The -f option is not used to specify a file for the wall command
○ wall reads input from standard input, not from a file flag
• D. wall --file maintenance_notice.txt
○ The wall command does not support a --file option
○ The correct approach is to use a pipe with cat
Question 3:
You've encountered an issue where a specific module, badmod, is causing system instability when loaded. You decide to prevent the module from being loaded automatically. Which file would you create or modify in /etc/ to blacklist the module?
A. /etc/modprobe.conf
B. /etc/modules/badmod.conf
C. /etc/modprobe.d/blacklist.conf
D. /etc/kernel/badmod.list
Answer: C
Explanation:
To blacklist a kernel module, you typically add an entry such as:
blacklist badmod
to a configuration file located under /etc/modprobe.d/.
• While the exact filename can vary, blacklist.conf is a commonly used and recognized file for this purpose.
• Using files within /etc/modprobe.d/ is the standard and organized approach for managing module options and blacklisting.
Incorrect
• A. /etc/modprobe.conf
○ Can contain module configurations
○ However, modern systems recommend using individual files in /etc/modprobe.d/ for better organization and maintainability
• B. /etc/modules/
○ Not a standard location for module blacklisting or configuration
• D. /etc/kernel/badmod.list
○ No standard file or directory exists with this name for module blacklisting
Question 4:
You're troubleshooting a server that's failing to boot correctly. While investigating, you discover that it uses the EXTLINUX bootloader. Which file should you check to ensure the bootloader's configuration is correct?
A. /boot/grub/grub.cfg
B. /boot/extlinux/extlinux.conf
C. /etc/fstab
D. /boot/syslinux/syslinux.cfg
Answer: B
Explanation:
For systems using the EXTLINUX bootloader, the primary configuration file is typically located at:
/boot/extlinux/extlinux.conf
This file defines key boot parameters, including:
• The kernel to boot
• The initial ramdisk (initrd)
• Other boot-time options
EXTLINUX is designed for ext2/ext3/ext4 filesystems, and this file controls its boot behavior.
Incorrect:
• A. /boot/grub/grub.cfg
○ Configuration file for the GRUB bootloader
○ Not used by EXTLINUX
• C. /etc/fstab
○ Specifies filesystem mount points
○ Unrelated to bootloader configuration
• D. /boot/syslinux/syslinux.cfg
○ Used by SYSLINUX for FAT-based filesystems
○ Not applicable to EXTLINUX
Question 5:
While troubleshooting a system boot issue, an administrator decides to check the kernel ring buffer for any error messages. Which command would provide the most recent kernel messages?
A. /bin/dmesg | tail
B. /bin/dmesg -c
C. /bin/dmesg | grep error
D. /bin/dmesg -l warn
Answer: A
Explanation:
• The command /bin/dmesg displays the contents of the kernel ring buffer.
• Piping the output to tail shows only the most recent messages, which is ideal for troubleshooting recent issues.
Incorrect
• B. /bin/dmesg -c
○ Clears the kernel ring buffer after displaying messages
○ Not recommended if you want to retain logs for further troubleshooting
• C. /bin/dmesg | grep error
○ Filters for messages containing “error”
○ Does not necessarily show the most recent messages
• D. /bin/dmesg -l warn
• Filters output to warning messages only
Does not guarantee viewing the latest kernel messages

Question 6:
Michael, a new Linux system administrator, is asked to determine how many other modules depend on a particular module named my_module. Which command would help him determine this?
A. /sbin/lsmod | grep my_module
B. /sbin/lsmod --dependent my_module
C. /sbin/lsmod -d my_module
D. /sbin/lsmod --info my_module
Answer: A
Explanation:
• The command /sbin/lsmod lists all currently loaded kernel modules.
• Piping the output to grep my_module filters the results to show details for the specific module, including:
○ Module name
○ Size
○ Number of dependent modules
This is the standard method to check module details and dependencies.
Incorrect
• B. /sbin/lsmod --dependent
○ Incorrect because lsmod has no --dependent option
• C. /sbin/lsmod -d
○ Incorrect because lsmod does not support the -d option
• D. /sbin/lsmod --info
• Incorrect because lsmod does not have an --info option
Question 7:
While working on an UEFI-based system, your team leader mentions the use of efiboot.img in the context of bootable ISOs for Linux distributions. What is the primary purpose of this file?
A. It acts as a Master Boot Record (MBR) for ISOs
B. It contains the GRUB bootloader configuration
C. It serves as a container for UEFI boot files needed for the ISO
D. It is a compressed image of the Linux kernel
Answer: C
Explanation:
efiboot.img is a FAT-formatted filesystem image that contains the UEFI boot files required for booting UEFI-based systems.
When creating bootable ISOs for UEFI systems, this image ensures that all necessary boot files are encapsulated and accessible.
Incorrect
A. Acts as a Master Boot Record (MBR)
Incorrect because efiboot.img does not function as an MBR
B. Contains the GRUB bootloader configuration
Incorrect because it focuses on UEFI boot files, not GRUB configuration
D. Compressed Linux kernel image
Incorrect because efiboot.img is a filesystem image, not a kernel image
Question 8:
Lisa, a system administrator, needs to set up an autofs map for users home directories located on a remote NFS server nfs-server.company.com. The user home directories are located in /exports/users/. Which line should she include in the /etc/auto.home file to achieve this?
A. * nfs-server.company.com:/exports/users/&
B. /exports/users nfs-server.company.com:*
C. & nfs-server.company.com:/exports/users/*
D. /home/* nfs-server.company.com:/exports/users/&
Answer: A
Explanation:
• In autofs:
○ * acts as a wildcard for the key in a map file
○ & is a placeholder representing the key itself
• This configuration mounts a user’s home directory from the NFS server to the appropriate local directory automatically.
Incorrect
• B. Wrong format
○ The key should be on the left and the mount location on the right
○ Option B reverses this, so it’s invalid
• C. Misplaced &
○ The & placeholder represents the key (e.g., usernames)
○ It should appear in the mount path, not as the key
• D. Using /home/*
• Incorrect because keys in an autofs map file are represented with just *
• /home/* is not valid for the key definition
Question 9:
An administrator wants to gather a verbose list of all PCI devices on the system, along with their detailed configuration. Which command should they use to achieve this?
A. /sbin/lspci -k
B. /sbin/lspci -n
C. /sbin/lspci -v
D. /sbin/lspci -t
Answer: C
Explanation:
• The command /sbin/lspci -v provides verbose output for all PCI devices, including:
○ Vendor and device information
○ IRQ assignments
○ I/O port addresses
○ Additional configuration details
This makes it ideal for detailed PCI device inspection.
Incorrect
• A. /sbin/lspci -k
○ Shows kernel drivers handling each device
○ Does not provide a verbose list of device configurations
• B. /sbin/lspci -n
○ Displays PCI IDs numerically
○ Lacks detailed human-readable configuration information
• D. /sbin/lspci -t
• Shows a tree structure of PCI devices
• Does not provide verbose configuration details
Question 10:
After performing maintenance on a server, you need to ensure that the volume group vgWeb is active. Which command will you use to activate this volume group?
A. vgscan --activate vgWeb
B. vgactivate vgWeb
C. vgchange -a y vgWeb
D. lvchange -a y /dev/vgWeb
Answer: C
Explanation:
• The command vgchange -a y vgWeb is used to activate a volume group:
○ -a y → activates the volume group
○ vgWeb → name of the volume group to activate
This makes the logical volumes within the group available for use.
Incorrect
• A. vgscan --activate
○ vgscan scans all disks for volume groups and rebuilds caches
○ The --activate option does not exist with vgscan
• B. vgactivate
○ No such command exists in the LVM toolset
• D. lvchange
• Used to change attributes of logical volumes, not volume groups
