CompTIA Linux+ Certification Exam Sample Questions (Q105-Q110):

NEW QUESTION # 105
Which of the following would significantly help to reduce data loss if more than one drive fails at the same time?

  • A. Server clustering
  • B. RAID
  • C. Load balancing
  • D. VDI

Answer: B

Explanation:
RAID stands for Redundant Array of Independent Disks, which is a technology that combines multiple physical disks into a logical unit that provides improved performance, reliability, or both. RAID can significantly help to reduce data loss if more than one drive fails at the same time, depending on the RAID level used. For example, RAID 1 (mirroring) duplicates the data on two or more disks, so that if one disk fails, the data can be recovered from another disk. RAID 5 (striping with parity) distributes the data and parity information across three or more disks, so that if one disk fails, the data can be reconstructed from the remaining disks. RAID 6 (striping with double parity) extends RAID 5 by adding another parity block, so that if two disks fail, the data can still be recovered from the remaining disks. Reference: [What is RAID?]

  • A. test -f /etc/sudoers
  • B. sudo vi check
  • C. cat /etc/sudoers | tee test

Answer: D


NEW QUESTION # 108
A Linux system is failing to boot. The following error is displayed in the serial console:
[[1;33mDEPEND[Om] Dependency failed for /data.
[[1;33mDEPEND[Om] Dependency failed for Local File Systems
...
Welcome to emergency mode! After logging in, type "journalctl -xb" to viewsystem logs,
"systemctl reboot" to reboot, "systemctl default" to try again to boot into default mode.
Give root password for maintenance
(or type Control-D to continue)
Which of the following files will need to be modified for this server to be able to boot again?

  • A. /dev/sda
  • B. /ete/grub.conf
  • C. /etc/mtab
  • D. /etc/fstab

Answer: D

Explanation:
The file that will need to be modified for the server to be able to boot again is /etc/fstab. The
/etc/fstab file is a file that contains the information about the file systems that are mounted at boot time on Linux systems. The file specifies the device name, mount point, file system type, mount options, dump frequency, and pass number for each file system. The error message indicates that the dependency failed for /data, which is a mount point for a file system. This means that the system could not mount the /data file system at boot time, which caused the system to enter the emergency mode. The emergency mode is a mode that allows the administrator to log in as the root user and perform basic tasks such as repairing the system. The administrator should modify the /etc/fstab file and check the entry for the /data file system. The administrator should look for any errors or inconsistencies in the device name, file system type, or mount options, and correct them. The administrator should also verify that the device and the file system are intact and functional by using commands such as blkid, fdisk, fsck, or mount. The administrator should then reboot the system and see if the issue is resolved. The file that will need to be modified for the server to be able to boot again is /etc/fstab.
