6. 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

   • mdadm --remove /dev/md0 /dev/sdd1

   • mdadm --zero-superblock /dev/sdf3

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

   • mdadm /dev/md0 --offline /dev/sdc1

9. What is the minimum number of disks required in a fully redundant RAID5 array?

   • 1
   • 2
   • 3
   • 4
   • 5

10. A system has one hard disk and one CD writer which are both connected to SATA controllers. Which device represents the CD writer?

    • /dev/hdb

    • /dev/sdd

    • /dev/scd1

    • /dev/sr0

    • /dev/sr1

11. 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

12. 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
