どのコマンドが、そのオプションに応じて、開いているネットワーク接続、ルーティングテーブル、およびネットワークインターフェイスの統計情報を表示できます。 （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:
etstatbinnetstatssusrbinss
Explanation:
The netstat command, meaning network statistics, is a command-line utility in the Linux system to display network configuration and activity, including network connections, routing tables, interface statistics, masquerade connections, and multicast memberships1. The netstat command can display different types of network data depending on the command line option selected. Some of the common options are:
-a: This option displays active TCP connections, TCP connections with the listening state, as well as UDP ports that are being listened to.
-r: This option displays the routing table information, which is a list of rules that determine where the packets are sent.
-i: This option displays the network interface information, such as the name, MTU, RX-OK, TX-OK, etc.
-s: This option displays the network statistics by protocol, such as TCP, UDP, ICMP, IP, etc.
For example, to display the open network connections, one can run:
netstat -a
To display the routing table, one can run:
netstat -r
To display the network interface statistics, one can run:
netstat -i
To display the network statistics by protocol, one can run:
netstat -s

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:

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:

정답:
usrbinxwininfoxwininfo
Explanation:
The xwininfo command is a utility for displaying information about windows in X. It can show various attributes of a window, such as its location, size, depth, border width, visual class, colormap, map state, and event masks. The -metric option specifies that all dimensions should be displayed in metric units (millimeters) rather than pixels. By issuing the xwininfo -metric command and then clicking on a window, the administrator can determine the geometry of that window, including the decorations, in millimeters. Reference:
