Instead of supplying an explicit device in /etc/fstab for mounting, what other options may be used to identify the intended partition? (Choose TWO correct answers). NAME. FIND. LABEL. ID. UUID.

Which of the following commands lists all currently installed packages when using RPM package management?. yum --query --all. rpm --query --all. rpm --list --installed. rpm --query --list. yum --list --installed.

Which of the following commands are valid in the GRUB 2 configuration file? (Choose TWO correct answers). menuentry. kpartx. uefi. pxe-ifconfig. insmod.

What is the purpose of the ldd command?. It lists which shared libraries a binary needs to run. It installs and updates installed shared libraries. It turns a dynamically linked binary into a static binary. It runs a binary with an alternate library search path. It defines which version of a library should be used by default.

What can the Logical Volume Manager (LVM) be used for? (Choose THREE correct answers). To dynamically create or delete logical volumes. To create RAID 9 arrays. To create snapshots. To encrypt logical volumes. To dynamically change the size of logical volumes.

What are the main differences between GPT and MBR partition tables regarding maximum number and size of partitions? (Choose TWO correct answers). MBR can handle partition sizes up to 2.2 TB, whereas GPT supports sizes up to 9.4 ZB. By default, GPT can manage up to 128 partitions while MBR only supports four primary partitions. Both GPT and MBR support up to four primary partitions, each with up to 4096 TB. By default, GPT can manage up to 64 partitions while MBR only supports 16 primary partitions. MBR can handle partition sizes up to 4 TB, where as GPT supports partition sizes up to 128 ZB.

A backup software heavily uses hard links between files which have not been changed in between two backup runs. Which benefits are realized due to these hard links? (Choose TWO correct answers). The backup runs faster because hard links are asynchronous operations, postponing the copy operation to a later point in time. The backup consumes less space because the hard links point to the same data on disk instead of storing redundant copies. The old backups can be moved to slow backup media, such as tapes, while still serving as hard link target in new backups. The backup runs faster because, instead of copying the data of each file, hard links only change file system meta data. The backup is guaranteed to be uncharged because a hard linked file cannot be modied after its creation.

How many fields are in a syntactically correct line of /etc/fstab?. 6. 4. 5. 3. 7.

Running chmod 640 filea.txt as a regular user doesn’t update filea.txt’s permission. What might be a reason why chmod cannot modify the permissions?. filea.txt has the sticky bit set and a regular user cannot remove this permission. filea.txt is a symbolic link whose permissions are a fixed value which cannot be charged. filea.txt is owned by another user and a regular user cannot change the permissions of another user’s file. filea.txt has the SetUID bit set which imposes the restriction that only the root user can make changes to the file. filea.txt is a hard link whose permissions are inherited from the target and cannot be set directly.

Which of the following Linux filesystems preallocate a fixed number of inodes when creating a new filesystem instead of generating them as needed? (Choose TWO correct answers). ext3. JFS. procfs. ext2. XFS.

A yum repository can declare sets of related packages. Which yum command installs all packages belonging to the group admintools?. yum install admintools/*. yum taskinstall admintools. yum pkgsel --install admintools. yum collection install admintools. yum groupinstall admintools.

Which of the following commands sets the SetUID permission on the executable /bin/foo?. chmod 4755 /bin/foo. chmod 1755 /bin/foo. chmod 755+s /bin/foo. chmod 2755 /bin/foo. chmod u-s /bin/foo.

Which of the following commands installs the GRUB boot files into the currently active file systems and the boot loader into the first partition of the first disk?. grub-install /dev/sda1. grub-install /dev/sda0. grub-install current /dev/sda0. grub-install current /dev/sda1. grub-install /dev/sda.

Which of the following files are found in the /boot/ file system? (Choose TWO correct answers). Bash shell binaries. systemd target and service units. Linux kernel images. fsck binaries. Initial ramdisk images.

Which file defines the network locations from where the Debian package manager downloads software packages?. /etc/apt/apt.conf. /etc/dpkg/dpkg.cfg. /etc/dpkg/dselect.cfg. /etc/apt/sources.list. /etc/apt/apt.conf.d.

When removing a package on a system using dpkg package management, which dpkg option ensures configuration files are removed as well?. --remove. --declare. --clean. --purge. --vacuum.

Which of the following statements are correct when comparing Linux containers with traditional virtual machines (e.g. LXC vs. KVM)? (Choose THREE correct answers). Containers are completely decoupled from the host system’s physical hardware and can only use emulated virtual hardware devices. Fully virtualized machines can run any operating system for a specific hardware architecture within the virtual machine. The guest environment for fully virtualized machines is created by a hypervisor which provides virtual and emulated hardware devices. Containers on the same host can use different operating systems, as the container hypervisor creates separate kernel execution. Containers are a lightweight virtualization method where the kernel controls process isolation and resource management.

The installation of a local Debian package failed due to unsatisfied dependencies. Which of the following commands installs missing dependencies and completes the interrupted package installation?. apt-get all. apt-get autoinstall. dpkg-reconfigure --all. apt-get install -f. dpkg --fix --all.

Which file from the /proc/ file system contains a list of all currently mounted devices? (Specify the full name of the file, including path).

What directory contains configuration files for additional yum repositories? (Specify the full path to the directory).
