次のコマンドのどれが、名前が.txtで終わる現在のディレクトリ内のすべてのファイルを含むZIPアーカイブpoems.zipを作成しますか？
- A. zcat *.txt poems.zip
- B. zip *.txt > poems.zip
- C. zip cfz poems.zip *.txt
- D. cat *.txt | zip poems.zip
- E. zip poems.zip *.txt
正解：E
解説：
The zip command is used to create compressed archive files that can contain one or more files or directories. The zip command takes the name of the archive file as the first argument, followed by the names of the files or directories to be included in the archive. You can also use wildcards to match multiple files or directories with a common pattern. For example, the command zip poems.zip *.txt will create the ZIP archive poems.zip containing all files in the current directory whose names end in .txt. The other commands are either invalid or do not perform the desired operation. The command zip *.txt > poems.zip will try to create an archive for each file ending in .txt and redirect the output to poems.zip, which is not a valid archive file. The command zcat *.txt poems.zip will try to decompress and concatenate the contents of the files ending in .txt and poems.zip, which is not a valid ZIP file. The command zip cfz poems.zip *.txt will fail because the options c, f, and z are not valid for the zip command. The command cat *.txt | zip poems.zip will try to read the contents of the files ending in .txt from the standard input and create an archive named poems.zip, but this will not preserve the file names or attributes of the original files.

Explanation
A recursive directory listing is a way of displaying the files and folders in a directory and all its sub-directories. The recursive option can be used with various commands, such as ls, find, or dir, to list the files recursively. For example, the command ls -R will list all the files and folders inthe current directory and any sub-directories, showing the hierarchy of the file system123 A recursive directory listing does not include the permissions, ownership, or file system details ofthe files, unless specified by other options. For example, the command ls -lR will list the files recursively and also show the permissions, ownership, size, and modification date of each file1 A recursive directory listing also does not include a preview of the content of each file, unless specified by other options. For example, the command ls -R --file-type will list the files recursively and also show the file type indicator, such as / for directories, * for executable files, @ for symbolic links, etc1 References: 1: ls (Unix) - Wikipedia 2: Recursively List all directories and files - Stack Overflow 3: Why is ls -R called "recursive" listing? - Ask Ubuntu

質問 # 37
次の出力の情報のソースはどのファイルですか？ （2つ選択してください。）uid = 1000（bob）gid = 1000（bob）groups = 1000（bob）、10（wheel）、150（docker）、1001（libvirt）（wireshark）、989
- A. /etc/id
- B. /var/db/users
- C. /etc/passwd
- D. /etc/group
- E. /home/index
正解：C、D
解説：
The files /etc/passwd and /etc/group are the source of the information in the following output:
uid=1000 (bob) gid=1000 (bob) groups=1000 (bob), 10 (wheel), 150 (docker), 1001 (libvirt) (wireshark), 989 The /etc/passwd file contains information about user accounts, such as the username, password, user ID (UID), group ID (GID), full name, home directory, and login shell1. The /etc/group file contains information about groups, such as the group name, password, group ID (GID), and members2.
The output shows the UID, GID, and group membership of the user bob. The UID and GID of bob are 1000, which can be found in the /etc/passwd file. The groups that bob belongs to are bob, wheel, docker, libvirt, wireshark, and 989, which can be found in the /etc/group file. The group names are shown in parentheses after the GID, except for the last group, which has no name.
The other options are not files that store user and group information in Linux. The /etc/id file does not exist by default. The /home/index file is not a standard file and has no relation to user and group information. The /var/db/users file is not a standard file and has no relation to user and group information.

Raspberry Piのオペレーティングシステムはどこに保存されていますか？
- A. Raspberry Piに装着されているリムーバブルSDカード
- B. Raspberry Piに内蔵されている書き換え可能なフラッシュストレージ。
- C. Raspberry PiのGPIOピンに接続されているLinux拡張モジュール上。
- D. Raspberry PiのファームウェアのBIOSの横にある読み取り専用パーティション。
- E. Raspberry PiのIDEバスに接続されているマスターデバイスです。
正解：A
解説：
Explanation
The Raspberry Pi uses an SD card (or microSD card for newer models) as its main storage device. This means that the operating system and any other files are stored on the SD card, which can be easily inserted or removed from the Raspberry Pi. The SD card also allows the user to switch between different operating systems by using different cards or partitions. The Raspberry Pi does not have any internal storage, such as a hard disk drive or a solid state drive, nor does it use any external devices, such as an IDE bus, a firmware partition, or a GPIO module, to store the operating system.

質問 # 40
次のコマンドのうち、圧縮アーカイブfile1.tar.gzの内容を抽出するものはどれですか？
- A. tar -xzf file1.tar.gz
- B. detar file1.tar.gz
- C. tar -czf file1.tar.gz
- D. tar --extract file1.tar.gz
- E. ztar file1.tar.gz
正解：A
解説：
Explanation
The correct command to extract the contents of the compressed archive file1.tar.gz is tar -xzf file1.tar.gz. This command uses the following options:
* -x means extract files from an archive.
* -z means filter the archive through gzip, which is a compression program that reduces the size of files.
* -f means use the following archive file name, which is file1.tar.gz in this case.
The other commands are incorrect for the following reasons:
* tar -czf file1.tar.gz creates a compressed archive file1.tar.gz from the files specified after the command, not extract it.
* ztar file1.tar.gz is not a valid command, as ztar is not a standard program or option for tar.
* tar --extract file1.tar.gz is missing the -z option to handle the gzip compression, and also the -f option to specify the file name.
* detar file1.tar.gz is not a valid command, as detar is not a standard program or option for tar.

質問 # 42
コマンドchmod 654 file.txtを使用して権限が変更されると、通常のファイルにどの権限が設定されますか。
- A. -rw-r-xr--
- B. -rwxrw---x
- C. d-wxr-x--
- D. -wxr-x--x
- E. drw-r-xr--
正解：A
解説：
Explanation
The chmod command is used to change the permissions of files and directories. The permissions are represented by three sets of three characters, indicating the permissions for the owner, the group, and the others. Each character can be either r (read), w (write), x (execute), or - (no permission). The chmod command can use either symbolic or numeric mode to specify the permissions. In this question, the numeric mode is used, which consists of three digits from 0 to 7. Each digit is the sum of the permissions for each set, where r is 4, w is 2, and x is 1. For example, 7 means rwx, 6 means rw-, and 4 means r-. Therefore, the command chmod 654 file.txt sets the permissions as follows:
* The first digit 6 means rw- for the owner, which means the owner can read and write the file, but not execute it.
* The second digit 5 means r-x for the group, which means the group can read and execute the file, but not write it.
* The third digit 4 means r-- for the others, which means the others can only read the file, but not write or execute it.
The resulting permissions are -rw-r-xr-, which is the correct answer. The other options are incorrect because they either have the wrong permissions or the wrong file type. A regular file does not have the d (directory) prefix, and a directory cannot have the - (no file type) prefix. References:

リバースDNSは、ホスト名をIPアドレスに割り当てます。 DNSサーバーに保存されているIPアドレス198.51.100.165の名前はどのようになっていますか？
- A. In the RNAME record for198-51-100-165.rev.arpA.
- B. In the PTR record for165.100.51.198.in-addr.arpA.
- C. In the REV record forarpA.in-addr.198.51.100.165.
- D. In the A record for165.100.51.198.ipv4.arpA.
- E. In the ARPA record for165.100.51.198.rev.
正解：B
解説：
Explanation
Reverse DNS lookups query DNS servers for a PTR (pointer) record; if the server does not have a PTR record, it cannot resolve a reverse lookup. PTR records store IP addresses with their segments reversed, and they append ".in-addr.arpa" to that. For example, if a domain has an IP address of 192.0.2.1, the PTR record will store the domain's information under 1.2.0.192.in-addr.arpa. In IPv6, the latest version of the Internet Protocol, PTR records are stored within the ".ip6.arpa" domain instead of ".in-addr.arpa."1 Therefore, the name of the IP address 198.51.100.165 is stored in the PTR record for
165.100.51.198.in-addr.arpa. References: 1: Reverse DNS lookup - Wikipedia 1

Red HatベースのLinuxシステムではどのパッケージ管理ツールが使用されていますか？
- A. packagectl
- B. portage
- C. apt-get
- D. dpkg
- E. rpm
正解：E
解説：
Explanation
RPM stands for RPM Package Manager (formerly known as Red Hat Package Manager), which is a powerful, command-line package management tool developed for the Red Hat operating system. It is now used as a core component in many Linux distributions such as CentOS, Fedora, Oracle Linux, openSUSE and Mageia1. RPM can install, uninstall,and query individual software packages, but it cannot manage dependency resolution like YUM2. YUM is another package management tool that is based on RPM and can handle dependencies automatically. YUM is the primary package management tool for installing, updating, removing, and managing software packages in Red Hat Enterprise Linux2. Therefore, the correct answer is B. rpm, as it is the underlying package management tool used in Red Hat-based Linux systems. References:
