Which type of file system is created by mkfs when it is executed with the block device name only and without any additional parameters?. ext3. ext4. VFAT. XFS. ext2.

In order to display all currently mounted filesystems, which of the following commands could be used? (Choose TWO correct answers). cat /proc/filesystems. mount. cat /proc/self/mounts. lsmounts. free.

Which chown command changes the ownership to dave and the group to staff on a file named data.txt?. chown dave+staff data.txt. chown –u dave –g staff data.txt. chown dave:staff data.txt. chown dave/staff data.txt. chown --user dave --group staff data.txt.

When considering the use of hard links, what are valid reasons not to use hardlinks?. Each hard link has individual ownership, permissions and ACLs which can lead to unintended disclosure of file content. If users other than root should be able to create hard links, suln has to be installed and configured. Hard links are specific to one filesystem and cannot point to files on another filesystem. When a hard linked file is changed, a copy of the file is created and consumes additional space. Hard links are not available on all Linux systems because traditional filesystems, such as ext4, do not support them.

In compliance with the FHS, in which of the directories are man pages found?. /var/man/. /opt/man/. /var/pkg/man. /usr/doc/. /usr/share/man/.

What is the process ID number of the init process on a System V init based system?. -1. It is different with each reboot. 0. 1. It is set to the current run level.

Which daemon handles power management events on a Linux system?. batteryd. acpid. inetd. pwrmgntd. psd.

Which of the following statements are true about the boot sequence of a PC using a BIOS? (Choose TWO correct answers). The BIOS is started by loading hardware drivers from secondary storage, such as the hard disk. The BIOS boot process starts only if secondary storage, such as the hard disk, is functional. Linux does not require the assistance of the BIOS to boot a computer. The BIOS initiates the boot process after turning the computer on. Some parts of the boot process can be configured from the BIOS.

What is true regarding UEFI firmware? (Choose TWO correct answers). It stores its entire configuration on the /boot/ partition. It is stored in a special area within the GPT metadata. It can use and read certain file systems. It is loaded from a fixed boot disk position. It can read and interpret partition tables.

Which umask value ensures that new directories can be read, written and listed by their owning user, read and listed by their owning group and are not accessible at all for everyone else?. 0027. 0750. 0029. 0036. 7640.

A faulty kernel module is causing issues with a network interface card. Which of the following actions ensures that this module is not loaded automatically when the system boots?. Using lsmod --remove --autoclean without specifying the name of a specific module. Using modinfo –k followed by the name of the offending module. Adding a blacklist line including the name of the offending module to the file /etc/modprobe.d/blacklist.conf. Using modprobe –r followed by the name of the offending module. Deleting the kernel module’s directory from the file system and recompiling the kernel, including its modules.

Which of the following commands changes the number of days before the ext3 filesystem on /dev/sda1 has to run through a full filesystem check while booting?. tune2fs –i 200 /dev/sda1. tune2fs –d 200 /dev/sda1. tune2fs --days 200 /dev/sda1. tune2fs –c 200 /dev/sda1. tune2fs –n 200 /dev/sda1.

Which is the default percentage of reserved space for the root user on new ext4 filesystems?. 0%. 15%. 5%. 3%. 10%.

Which of the following is true when a file system, which is neither listed in /etc/fstab nor known to system, is mounted manually?. systemd automatically generates a mount unit and monitors the mount point without changing it. The command systemctl mountsync can be used to create a mount unit based on the existing mount. systemd ignores any manual mounts which are not done using the systemctl mount command. Unless a systemd mount unit is created, systemd unmounts the file system after a short period of time. systemctl unmount must be used to remove the mount because system opens a file descriptor on the mount point.

What does the command mount --bind do?. It makes the contents of one directory available in another directory. It mounts all available filesystems to the current directory. It permanently mounts a regular file to a directory. It mounts all file systems listed in /etc/fstab which have the option userbind set. It mounts all user mountable filesystems to the user’s home directory.

Consider the following output from the command ls –i: How would a new file named c.txt be created with the same inode number as a.txt (Inode 525385)?. ln –f c.txt a.txt. ln c.txt a.txt. ln –h a.txt c.txt. ln a.txt c.txt. ln –i 525385 c.txt.

Consider the following directory: drwxrwxr-x 2 root sales 4096 Jan 1 15:21 sales Which command ensures new files created within the directory sales are owned by the group sales? (Choose TWO correct answers). chmod 2775 sales. chgrp –p sales sales. chmod g+s sales. setpol –R newgroup=sales sales. chown --persistent *.sales sales.

Which command displays the current disk space usage for all mounted file systems? (Specify ONLY the command without any path or parameters).

Which file in the /proc filesystem lists parameters passed from the bootloader to the kernel? (Specify the file name only without any path).

Which program updates the database that is used by the locate command? (Specify ONLY the command without any path or parameters).
