存在する場合、どのファイルにcronスケジューリングシステムの使用を許可されているすべてのユーザーをリストする必要がありますか？ （パスを含むファイルのフルネームを指定してください。）
정답:
etccronallow
Explanation:
The /etc/cron.allow file is a file that contains a list of users who are allowed to use the cron scheduling system. The cron scheduling system is a way of running commands or scripts at specified times or intervals. Users can create their own cron jobs by using the crontab command, which edits a file called crontab that stores the user's scheduled tasks. However, not all users may have access to the crontab command or the cron system. The access is controlled by two files: /etc/cron.allow and /etc/cron.deny. If the /etc/cron.allow file exists, then only the users listed in this file can use the crontab command and the cron system. The file should have one user name per line. If the /etc/cron.allow file does not exist, then the /etc/cron.deny file is checked. If this file exists, then the users listed in this file are denied access to the crontab command and the cron system. If neither file exists, then the access depends on the configuration of the cron daemon, which is the program that runs the cron jobs. By default, only the root user can use the cron system if no files exist. The root user can always use the cron system regardless of the existence or content of these files. To create or edit the /etc/cron.allow file, the root user needs to use a text editor such as vi, nano, or emacs. For example, to allow the users alice and bob to use the cron system, the root user can use the following command:
sudo vi /etc/cron.allow
And then add the following lines to the file:
alice bob
And then save and exit the file. Reference:

IPv4サブネット192.168.2.128/28内の固有のホストにはいくつのIPアドレスを使用できますか？ （追加情報なしで番号のみを指定してください。）
정답:
14
Explanation:
To find the number of IP-addresses that can be used for unique hosts inside an IPv4 subnet, we need to calculate the number of bits that are used for the host part of the IP address. The host part is the part that is not used for the network prefix, which is indicated by the slash notation (/) followed by a number. The number after the slash represents the number of bits that are used for the network prefix, out of the total 32 bits of an IPv4 address. The remaining bits are used for the host part. For example, in the subnet 192.168.2.128/28, the number 28 means that the first 28 bits are used for the network prefix, and the last 4 bits are used for the host part.
The number of IP-addresses that can be used for unique hosts is equal to 2^n - 2, where n is the number of bits in the host part. The -2 is because the first and the last IP addresses in a subnet are reserved for the network address and the broadcast address, respectively, and cannot be assigned to hosts. Therefore, in the subnet 192.168.2.128/28, the number of IP-addresses that can be used for unique hosts is 2^4 - 2, which is 14.

バニラX11のインストールに付属のシンプルなグラフィカルログインマネージャの名前は何ですか？ （パスまたはパラメーターを指定せずにコマンドのみを指定してください。）
정답:
xdm
Explanation:
The name of the simple graphical login manager that comes with a vanilla X11 installation is xdm. XDM is the traditional graphical login manager for the X Window System, independent of any window manager or environment the user might choose. When it is run at system startup, it displays a graphical login prompt rather than the text-based login prompt at the console1. XDM is part of the xorg-x11-apps package, which provides the basic applications for the X Window System2. XDM is also one of the topics covered by the LPI Linux Professional - Exam 102 Objectives - Topic 111: Graphical Desktops3. Reference:

Xorg X11サーバー用の設定ファイルのデフォルト名は何ですか？ （ファイル名はパスなしでのみ指定してください。）
정답:
xorgconf
Explanation:
The default name of the configuration file for the Xorg X11 server is xorg.conf. This file is used to store initial setup for X, such as settings for video cards, monitors, input devices, and other options. The Xorg X11 server is a display server that uses a configuration file called xorg.conf and files ending in the suffix .conf for its initial setup1. The xorg.conf file is typically located in /etc/X11/xorg.conf, but its location may vary across operating system distributions2. The xorg.conf file is not mandatory, as the Xorg X11 server can automatically configure most hardware and settings. However, it can be created and edited manually if needed3. Reference:
