CompTIA Linux+ Certification Exam Sample Questions (Q50-Q55):

NEW QUESTION # 50
A systems administrator is encountering performance issues. The administrator runs 3 commands with the following output

The Linux server has the following system properties
CPU: 4 vCPU
Memory: 50GB
Which of the following accurately describes this situation?

  • A. The system is under CPU pressure and will require additional vCPUs
  • B. The system has been running for over a year and requires a reboot.
  • C. The system requires more memory
  • D. Too many users are currently logged in to the system

Answer: A

Explanation:
Based on the output of the image sent by the user, the system is under CPU pressure and will require additional vCPUs. The output shows that there are four processes running upload.sh scripts that are consuming a high percentage of CPU time (99.7%, 99.6%, 99.5%, and 99.4%). The output also shows that the system has only 4 vCPUs, which means that each process is using almost one entire vCPU. This indicates that the system is struggling to handle the CPU load and may experience performance issues or slowdowns.
Adding more vCPUs to the system would help to alleviate the CPU pressure and improve the system performance. The system has not been running for over a year, as the uptime command shows that it has been up for only 1 day, 2hours, and 13 minutes. The number of users logged in to the system is not relevant to the performance issue, as they are not consuming significant CPU resources. The system does not require more memory, as the free command shows that it has plenty of available memory (49 GB total, 48 GB free).

NEW QUESTION # 52
A junior developer is unable to access an application server and receives the following output:

The systems administrator investigates the issue and receives the following output:

Which of the following commands will help unlock the account?

  • A. pam_ tally2 --user=dev2
  • B. Pam_tally2 --user=dev2 --quiet
  • C. pam_tally2 --user=dev2 --reset
  • D. pam_tally2 --user+dev2 --quiet

Answer: C

Explanation:
Explanation
To unlock an account that has been locked due to login failures, the administrator can use the command pam_tally2 --user=dev2 --reset (D). This will reset the failure counter for the user "dev2" and allow the user to log in again. The other commands will not unlock the account, but either display or increase the failure count.

NEW QUESTION # 53
A Linux system is failing to start due to issues with several critical system processes. Which of the following options can be used to boot the system into the single user mode? (Choose two.)

  • A. Interrupt the boot process in the GRUB menu and add single=user in the kernel line.
  • B. Interrupt the boot process in the GRUB menu and add systemd.unit=single in the kernel line.
  • C. Interrupt the boot process in the GRUB menu and add init=/bin/bash in the kernel line.
  • D. Interrupt the boot process in the GRUB menu and add systemd.unit=single.target in the kernel line.
  • E. Interrupt the boot process in the GRUB menu and add systemd.unit=rescue.target in the kernel line.
  • F. Execute the following command from the GRUB rescue shell: mount -o remount, ro/sysroot.

Answer: D,E

Explanation:
Explanation
The administrator can use the following two options to boot the system into the single user mode:
Interrupt the boot process in the GRUB menu and add systemd.unit=rescue.target in the kernel line. This option will boot the system into the rescue mode, which is a minimal environment that allows the administrator to perform basic tasks such as repairing the system. The GRUB menu is a screen that appears when the system is powered on and allows the administrator to choose which kernel or operating system to boot. The kernel line is a line that specifies the parameters for the kernel, such as the root device, the init system, and the boot options. The administrator can interrupt the boot process by pressing the e key in the GRUB menu and edit the kernel line by adding systemd.unit=rescue.target at the end. This option will tell the system to use the rescue target, which is a unit that defines the state of the system in the rescue mode. The administrator canthen press Ctrl+X to boot the system with the modified kernel line. This option will boot the system into the single user mode and allow the administrator to troubleshoot the issues.
Interrupt the boot process in the GRUB menu and add systemd.unit=single.target in the kernel line. This option will boot the system into the single user mode, which is a mode that allows the administrator to log in as the root user and perform maintenance tasks. The GRUB menu and the kernel line are the same as the previous option. The administrator can interrupt the boot process by pressing the e key in the GRUB menu and edit the kernel line by adding systemd.unit=single.target at the end. This option will tell the system to use the single target, which is a unit that defines the state of the system in the single user mode. The administrator can then press Ctrl+X to boot the system with the modified kernel line.
This option will boot the system into the single user mode and allow the administrator to troubleshoot the issues.
The other options are incorrect because they either do not boot the system into the single user mode (execute the following command from the GRUB rescue shell: mount -o remount, ro/sysroot or interrupt the boot process in the GRUB menu and add systemd.unit=single in the kernel line) or do not use the correct syntax (interrupt the boot process in the GRUB menu and add single=user in the kernel line or interrupt the boot process in the GRUB menu and add init=/bin/bash in the kernel line).

  • C. rpm -query /etc/httpd/conf/httpd.conf
  • D. rpm -ql /etc/httpd/conf/httpd.conf
