CompTIA Linux+ Certification Exam Sample Questions (Q30-Q35):

NEW QUESTION # 30
A Linux administrator needs to set the permissions on a server. The administrator wants to have the files within the directory set to read-write permissions and the directory set to read-write-execute permissions.
Which of the following commands should the administrator use?

A. umask 0077
B. chown 0027
C. setfacl 0007
D. chmod 0022

Answer: C

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* setfacl (Set File Access Control Lists) is used to define more granular permissions for files and directories.
* chmod 0022 sets specific permissions on files but does not affect newly created files.
* chown 0027 is incorrect because chown is used to change file ownership, not permissions.
* umask 0077 restricts permissions too much, making files private rather than just read/write.

NEW QUESTION # 31
A Linux systems administrator is troubleshooting an I/O latency on a single CPU server. The administrator runs a top command and receives the following output:
%Cpu(s): 0.2 us, 33.1 sy, 0.0 ni, 0.0 id, 52.4 wa, 0.0 hi, 0.2 si, 0.0 st Which of the following is correct based on the output received from the executed command?

A. The server's CPU is spending too much time waiting for data inputs.
B. The server's CPU is taking too long to process users' requests.
C. The server's CPU value for the time spent on system processes is low.
D. The server's CPU shows a high idle-time value.

Answer: A

Explanation:
The server's CPU is spending too much time waiting for data inputs. This can be inferred from the output of the top command, which shows the percentage of CPU time spent in different states. The wa state stands for wait, and it indicates that the CPU is idle while waiting for an I/O operation to complete. In this case, the wa state is 52.4%, which means that more than half of the CPU time is wasted on waiting for data inputs. This can cause a high I/O latency and affect the performance of the server.
The other options are not correct based on the output received from the executed command. The server's CPU is not taking too long to process users' requests, because the us state, which stands for user, is only 0.2%, which means that the CPU is barely used by user processes. The server's CPU does not show a high idle-time value, because the id state, which stands for idle, is 0.0%, which means that the CPU is not idle at all. The server's CPU value for the time spent on system processes is not low, because the sy state, which stands for system, is 33.1%, which means that the CPU is heavily used by system processes.

NEW QUESTION # 32
Which of the following would significantly help to reduce data loss if more than one drive fails at the same time?

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

Answer: D

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. References: [What is RAID?]

NEW QUESTION # 33
A systems administrator is investigating an issue in which one of the servers is not booting up properly. The journalctl entries show the following:

Which of the following will allow the administrator to boot the Linux system to normal mode quickly?

A. Trigger a filesystem relabel and reboot.
B. Perform filesystem checks on local filesystems and reboot.
C. Reformat the /opt/app filesystem and reboot.
D. Comment out the /opt/app filesystem in /etc/fstab and reboot.

Answer: D

Explanation:
Explanation
The fastest way to boot the Linux system to normal mode is to comment out the /opt/app filesystem in
/etc/fstab and reboot. This will prevent the system from trying to mount the /opt/app filesystem at boot time, which causes an error because the filesystem does not exist or is corrupted. Commenting out a line in /etc/fstab can be done by adding a # symbol at the beginning of the line. Rebooting the system will apply the changes and allow the system to boot normally. Reformatting the /opt/app filesystem will not help to boot the system, as it will erase any data on the filesystem and require manual intervention to create a new filesystem.
Performing filesystem checks on local filesystems will not help to boot the system, as it will not fix the missing or corrupted /opt/app filesystem. Triggering a filesystem relabel will not help to boot the system, as it will only change the security context of files and directories according to SELinux policy.

NEW QUESTION # 34
A Linux system is failing to boot with the following error:

Which of the following actions will resolve this issue? (Choose two.)

A. Interrupt the boot process in the GRUB menu and add rescue to the kernel line.
B. Execute grub-install /dev/sdX and reboot.
C. Interrupt the boot process in the GRUB menu and add single to the kernel line.
D. Fix the partition modifying /etc/default/grub and reboot.
E. Execute grub-install --root-directory=/mnt and reboot.
F. Boot the system on a LiveCD/ISO.

Answer: B,F

Explanation:
The administrator should do the following two actions to resolve the issue:
* Boot the system on a LiveCD/ISO. This is necessary to access the system and repair the boot loader. A LiveCD/ISO is a bootable media that contains a Linux distribution that can run without installation. The administrator can boot the system from the LiveCD/ISO and mount the root partition of the system to a temporary directory, such as /mnt.
* Execute grub-install /dev/sdX and reboot. This will reinstall the GRUB boot loader to the disk device, where sdX is the device name of the disk, such as sda or sdb. The GRUB boot loader is a program that runs when the system is powered on and allows the user to choose which operating system or kernel to boot. The issue is caused by a corrupted or missing GRUB boot loader, which prevents the system from booting. The command grub-install will restore the GRUB boot loader and fix the issue.
The other options are incorrect because they either do not fix the boot loader (interrupt the boot process in the GRUB menu or fix the partition modifying /etc/default/grub) or do not use the correct syntax (grub-install -- root-directory=/mnt instead of grub-install /dev/sdX or rescue or single instead of recovery in the GRUB menu).
