• configure

• config.h.in

• makefile

• Makefile

• Makefile.in

Which of the following commands restores only those files containing lpi in their name from the archive lpifiles.tar.gz?

• tar xvzf lpifiles.tar.gz --wildcards "˜*lpi*'

• tar xvzwf lpifiles.tar.gz "˜*lpi*'

• tar -xvfz lpifiles.tar.gz --deep "˜*lpi*'

• tar -xvzf lpifiles.tar.gz --subdirs "˜*lpi*'

A regular user has just run ./configure && make && make install

to build and install a program. However, the installation fails. What could be done to install the program? (Choose two.)

• Install the binaries manually with suinstall

• Run make install with root privileges

• Do not run ./configure in order to maintain the default configuration for correct installation

• Rerun ./configure with a --prefix option where the user has permissions to write

• Run make install_local to install into /usr/local/

The following command has just been run successfully:

Cd /opt; tar xvf /dev/nst0;

What will happen if the command sequence is run again?

• An error saying that there is no tape present is generated because the tape has been ejected after being used

• The contents of /opt will be restored again

• The entire contents of /opt will be replaced with the contents of the next file on the tape

• The contents of /opt will have additional content added from the next file on the tape

What command discards unused blocks on a mounted file system in order to support SSD devices? (Specify ONLY the command without any path or parameters.)

Which single command simulates a failed device within a RAID 5 array?

• mdadm --remove /dev/md0 /dev/sdd1

• mdadm --zero-superblock /dev/sdf3

• mdadm --force-fault /dev/md2 /dev/sde2

• mdadm --fail /dev/md0 /dev/sdc1

• mdadm /dev/md0 --offline /dev/sdc1

What action should be performed after increasing the size of a logical volume?

• Run vgresize

• Increase the size of the filesystem used for the logical volume

• Run 1vresize

• Remount the logical volume

What information is found in the following excerpt from the file /proc/mdstat? (Choose two.)

• One of the disks in /dev/md0 has failed and a spare disk is used to recreate full redundancy

• The spare disk /dev/sda1 is used to restore full redundancy after the current recovery

• The information [UU_] means, that the raid is missing one disk and is not fully redundant

• The device is using version 1.2 metadata to allow LILO and GRUB Legacy to use /dev/md0 as the boot partition. This would not have been

  necessary with GRUB2

• The information [3/2] means that 3 RAID disks belong to the array and 2 disks are spare. Together they equal the number of available disks

What command will remove a physical volume from a volume group? (Specify ONLY the command without any path or parameters.)

What is the purpose of a system mount unit?

• It is used by the command systemd-mount and allows users to mount partitions to mount points of their choice

• It is used only to mount network file systems to local mount points. It cannot be used for local media

• It is created by the command systemd-fstab-generator to integrate entries from /etc/fstab into the system boot process

• It is used by the command mount when using system to mount and unmount file systems
