EX294 Question #19: Real Exam Question with Answer & Explanation

Question

19. Create partitions (randomly selected with Question 9: creating logical volumes) Choose either partitions or LVM to complete. On the balancers host, perform partitioning: (1) Create a new partition on /dev/vdb, partition number 1, size 1500 MB, format it as ext4, and mount it to the /newpart1 directory. If there is not enough space, create a 800 MB partition instead. (Exam environment: /dev/vdb size is 2 GB.) (2) Create a new partition on /dev/vdc, partition number 1, size 1500 MB, format it as ext4, and mount it to the /newpart2 directory. If there is not enough space, create a 800 MB partition instead. (Exam environment: /dev/vdc size is 1 GB.) (3) If the volume group vdd does not exist, an error message should be displayed: Volume group vdd not exist Exam note: First check the target node to see which disk has enough space for 1500 MB, and perform that one first. For example, if /dev/vdc has enough space for 1500 MB, then the block of tasks should first partition /dev/vdc.
