Lpi LPIC-1 Exam 102, Part 2 of 2, version 5.0 Sample Questions (Q73-Q78):

NEW QUESTION # 73
Which command included in systemd supports selecting messages from the systemd journal by criteria such as time or unit name? (Specify only the command without any path or parameters.)

Answer:

Explanation:
journalctl
Explanation:
The command journalctl is included in systemd and supports selecting messages from the systemd journal by criteria such as time or unit name. The systemd journal is a binary log file that stores system and service messages. The journalctl command can be used to view, filter, export, and manipulate the journal entries. For example, to show all messages from a specific unit, such as sshd.service, the command would be:
journalctl -u sshd.service
To show all messages from a specific time range, such as yesterday, the command would be:
journalctl --since=yesterday
The journalctl command has many options and arguments that can be used to customize the output and perform various operations on the journal. For more information, see the man page of journalctl or the official documentation1. Reference: [LPI 102-500 Exam Objectives], Topic 106.2: System logging, Weight: 3. [systemd-journald.service(8) - systemd - Debian unstable - Debian Manpages], Section NAME.

NEW QUESTION # 75
The presence of what file will temporarily prevent all users except root from logging into the system? (Specify the full name of the file, including path.)

Answer:

Explanation:
etcnologin
Explanation:
The /etc/nologin file is used to prevent all users except root from logging into the system. This file is usually created by the system administrator when the system is going down for maintenance or reboot. The file can contain a message that is displayed to the users who try to log in, explaining the reason for the system shutdown. The file is automatically removed by the system when it boots up again.

NEW QUESTION # 76
Which file specifies the user accounts that can NOT submit jobs via at or batch? (Provide the full path and filename)

Answer:

Explanation:
etcatdeny
Explanation:
The /etc/at.deny file specifies the user accounts that can NOT submit jobs via at or batch. The format of the file is a list of usernames, one on each line. Whitespace is not permitted. The superuser may always use at. If the file /etc/at.allow exists, only usernames mentioned in it are allowed to use at. If /etc/at.allow does not exist, /etc/at.deny is checked12. The at and batch commands use the files /usr/lib/cron/at.allow and /usr/lib/cron/at.deny to restrict usage on some systems3. Reference:
at.allow(5) - Linux man page
at.deny(5) [linux man page] - The UNIX and Linux Forums
The at.allow and at.deny files - IBM

NEW QUESTION # 77
Which of the following commands can be used to limit the amount of memory a user may use?

A. usermod
B. ulimit
C. umask
D. chage
E. passwd

Answer: B

Explanation:
The ulimit command can be used to limit the amount of memory a user may use. The ulimit command is a shell builtin that allows the user to view or modify the resource limits imposed by the operating system. The resource limits can affect the maximum size of files, the maximum number of processes, the maximum amount of CPU time, and the maximum amount of virtual memory a user can access.
To limit the amount of memory a user may use, the -v option can be used with the ulimit command. The -v option sets the maximum amount of virtual memory available to the current shell and its children in kilobytes.
For example, the command ulimit -v 1000000 would limit the virtual memory to 1 GB. The -m option can also be used to set the maximum resident set size, which is the amount of physical memory used by a process, but this option is not supported by all systems.
The ulimit command can be used interactively in a shell session, or it can be placed in a shell initialization file, such as .bashrc or .profile, to apply the limits to all future shell sessions. The ulimit command can also be used in conjunction with the /etc/security/limits.conf file, which allows the system administrator to set global or per-user resource limits for all users and processes. The /etc/security/limits.conf file can specify hard and soft limits for each resource, as well as the scope of the limit, such as user, group, or domain.
The other commands listed are not related to limiting the amount of memory a user may use. The umask command sets the default file permissions for newly created files and directories. The usermod command modifies the user account information, such as the home directory, the login shell, or the password expiration date. The passwd command changes the user password. The chage command changes the password aging information, such as the minimum and maximum number of days between password changes, or the number of days before the password expires. References:
* ulimit(1) - Linux manual page
* How to limit user environment with ulimit Linux command
* Control server access using hosts.allow and hosts.deny files
