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, instead of copying the data of each file, hard links only change file system meta data. The backup runs faster because hard links are asynchronous operations, postponing the copy operation to a later point in time. The old backup can be moved to slow backup media, such as tapes, while still serving as hard link target in new backups. The backup is guaranteed to be unchanged because the hard links point to the same data on disk instead of storing redundant copies.

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

After a power outage, the XFS file system of /dev/sda3 is inconsistent. How can the existing file system errors be fixed?. By using mount -f to force a mount of the filesystem. By mounting the filesystem with the option xfs_repair. By running xfsck on the filesystem. By runnig xfsadmin repair on the filesystem. By running xfs_repair on the filesystem.

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). LABEL. UUID. NAME. FIND. ID.

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

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

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

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

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

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

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

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

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

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

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

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). procfs. ext3. JFS. XFS. ext2.

Which of the following setting for umask ensures that new files have the default permissions -rw-r-----?. 0017. 0038. 0027. 0227. 0640.

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. The guest environmnet for fully virtualized machines is created by a hypervisor which provides virtual an emulated hardware devices. Containers are a lightweight virtualization method where the kernel controls process isolation and resource management. Fully virtualized machines can run any operating system for a specific hardware and can only use emulated virtual machine. Containers on the same host can use different operating systems as the container hypervisor creates separate kernel execution environments.

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

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