LPIC-1 Timed Practice Test 2 — 10 Questions

Question 1

Refer to the exhibit. An administrator runs 'ntpq -p' and sees the output shown. What is the most likely cause of the '16' stratum and '0.000' delay/offset?

Accepted Answer

The NTP daemon has recently started and has not yet synchronized.. The '16' stratum and '0.000' delay/offset values in the 'ntpq -p' output indicate that the NTP daemon has not yet synchronized with any time source. When ntpd starts, it initially sets the stratum to 16 (unsynchronized) and shows zero values for delay and offset until it completes the synchronization process. This is a normal transient state that resolves once the daemon successfully contacts and synchronizes with an NTP server.

Answer

The NTP service is not running.

Answer

The firewall is blocking UDP port 123.

Answer

The restrict lines are blocking all NTP queries.

Question 2

Arrange the steps to troubleshoot a service that fails to start.

Question 3

Arrange the steps to configure a static IP address on a Linux system using the command line.

Question 4

Order the steps to create and apply a file system permission using ACLs.

Question 5

Order the steps to add a new user to the system and grant sudo privileges.

Question 6

Arrange the steps to create a LVM logical volume and mount it.

Question 7

An administrator needs to ensure that a specific kernel module is loaded automatically at boot. Which file should be used to permanently load the module?

Accepted Answer

/etc/modules. Option C is correct because on modern Linux systems using a standard init system, the file /etc/modules (or /etc/modules-load.d/*.conf on systemd-based distributions) is read at boot to load specified kernel modules automatically. This file lists module names one per line, and the kernel's module loading mechanism processes it early in the boot sequence to ensure the module is available before services that depend on it start.

Answer

/etc/modprobe.d/modules.conf

Answer

/etc/sysconfig/modules

Answer

/etc/conf.modules

Question 8

Which TWO commands can be used to display the amount of free and used memory on a Linux system? (Select exactly 2.)

Accepted Answer

cat /proc/meminfo. Option C is correct because `/proc/meminfo` is a virtual file maintained by the kernel that provides detailed, real-time memory statistics, including total, free, available, and used memory. Reading this file with `cat` directly displays the current memory usage without any additional processing.

Answer

vmstat

Question 9

A server has two disk drives: /dev/sda (SSD) and /dev/sdb (HDD). The administrator wants to place frequently accessed files on the SSD for performance. Which approach best achieves this using Linux filesystem features?

Accepted Answer

Create separate LVM logical volumes on each disk and mount them at different mount points.. Option A is correct because LVM allows the administrator to create separate logical volumes on each physical disk (/dev/sda and /dev/sdb) and mount them at distinct mount points. By placing frequently accessed files on the SSD logical volume and less critical data on the HDD logical volume, the administrator can directly control which files benefit from the SSD's faster performance without mixing data or requiring complex overlays.

Answer

Configure RAID 0 across both disks to combine speed.

Answer

Use symbolic links to redirect file access to the SSD.

Answer

Use a union mount to overlay the SSD on top of the HDD.

Question 10

Refer to the exhibit. The system has a single disk with three partitions. Which partition contains the root filesystem?

Accepted Answer

sda3. The root filesystem is mounted from the partition that contains the / (root) directory. In Linux, partitions are numbered starting from 1 (e.g., sda1, sda2, sda3). The device sda itself refers to the entire disk, not a partition. Since the system has three partitions and the correct answer is sda3, partition sda3 must be the one designated as the root filesystem, typically identified by the mount point '/' in /etc/fstab or by the kernel boot parameter root=.

Answer

sda

Answer

sda1

Answer

sda2
