- B. Each file is owned by exactly one user and one group.
- C. The owner of a file cannot be changed once it is assigned to an owner.
- D. The owner of a file always has full permissions when accessing the file.
- E. The user owning a file must be a member of the file's group.
正解：B
解説：
Explanation
In Linux, every file and directory is associated with an owner and a group. The owner is the user who created the file or directory, and the group is the group to which the owner belongs. Therefore, each file is owned by exactly one user and one group. This is true for option A. The other options are false for the following reasons:
* Option B: The owner of a file does not always have full permissions when accessing the file. The permissions are determined by the file mode, which can be changed by the owner or the root user. The file mode specifies the read, write, and execute permissions for the owner, the group, and others. The owner can have different permissions than the group or others.
* Option C: The user owning a file does not have to be a member of the file's group. The owner can change the group ownership of the file to any group on the system, regardless of whether the owner belongs to that group or not. However, only the root user or a user with the CAP_CHOWN capability can change the group ownership to a group that the owner is not a member of.
* Option D: When a user is deleted, all files owned by the user do not disappear. The files remain on the system, but their owner is changed to an invalid user ID (UID). The files can still be accessed by the group or others, depending on the permissions. The files can also be reclaimed by the root user or a user with the CAP_CHOWN capability, who can change the owner to a valid user.
* Option E: The owner of a file can be changed once it is assigned to an owner. The owner can transfer the ownership to another user, or the root user or a user with the CAP_CHOWN capability can change the owner to any user on the system. The command to change the owner of a file is chown.

質問 # 51
What is the UID of the user root?
- A. 0
- B. 1
- C. 2
- D. 3
- E. 4
正解：D
解説：
Explanation
The UID of the user root is always 0 on Linux systems. This is because the kernel uses the UID 0 to check for the superuser privileges and grant access to all system resources. The name of the user account with UID 0 is usually root, but it can be changed or have aliases. However, some applications may expect the name root and not work properly with a different name. The UID 0 is reserved for the root user and cannot be assigned to any other user. The UID 0 is stored in the /etc/passwd file along with other user information. References:

質問 # 55
A user is currently in the directory/home/user/Downloads/and runs the command ls ../Documents/ Assuming it exists, which directory's content is displayed?
- A. /home/Documents
- B. /home/user/Documents/
- C. /home/user/Downloads/Documents/
- D. /home/user/Documents/Downloads/
- E. /Documents/
正解：B
解説：
Explanation
The command ls .../Documents/ lists the contents of the directory /home/user/Documents/. The reason is that the argument .../Documents/ is a relative path that refers to the parent directory of the current directory, which is /home/user/, followed by the subdirectory Documents/. The ls command displays the files and directories in the specified path, or the current directory if no path is given. The command does not change the current directory, so the user remains in /home/user/Downloads/. References:

CentOS is a Linux distribution that is based on the source code of Red Hat Enterprise Linux (RHEL). It is a free and open-source community-supported OS that provides an enterprise-level computing platform. CentOS is fully compatible with RHEL and can run the same applications and packages. Therefore, CentOS allows the team members to apply as much of their Red Hat Enterprise Linux knowledge as possible for their hobby project. References:

質問 # 63
Which of the following commands sets the variable USERNAME to the value bob?
- A. USERNAME=bob
- B. var USERNAME=bob
- C. $USERNAME==bob
- D. USERNAME<=bob
- E. set USERNAME bob
正解：A
解説：
Explanation
The correct command to set the variable USERNAME to the value bob is USERNAME=bob. This command assigns the string bob to the variable name USERNAME, using the equal sign (=) as the assignment operator.
There is no space around the equal sign, and the variable name and value are case-sensitive. This command sets a shell variable, which is only valid in the current shell session. To make the variable an environment variable, which can be inherited by child processes and subshells, you need to use the export command, such as export USERNAME=bob. The other commands are not valid for setting variables in Linux. The set command is used to set orunset shell options and positional parameters, not variables. The $ sign is used to reference the value of a variable, not to assign it. The == sign is used for comparison, not assignment. The var keyword is not used in Linux, but in some other programming languages. The <= sign is used for redirection, not assignment. References:

質問 # 66
Which permissions are set on a regular file once the permissions have been modified with the command chmod 654 file.txt?
- A. -wxr-x--x
- B. drw-r-xr--
- C. d-wxr-x--
- D. -rw-r-xr--
- E. -rwxrw---x
正解：D
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:

質問 # 67
Which of the following characters in a shell prompt indicates the shell is running with root privileges?
- A. &
- B. !
- C. #
- D. $
- E. *
正解：C
解説：
Explanation
The shell prompt is a symbol or a string of characters that indicates the shell is ready to accept commands. The shell prompt can be customized by the user or by the system administrator. The default shell prompt for a normal user is usually a dollar sign ($), while the default shell prompt for the root user is usually a hash sign (#). The root user is the superuser or the administrator of the system, who has full access and control over all files, commands, and resources. Running commands as root can be dangerous, as it can cause irreversible damage to the system if done incorrectly. Therefore, it is advisable to use sudo or su to run commands as root only when necessary, and to switch back to a normal user as soon as possible. The shell prompt indicates the shell is running with root privileges when it ends with a hash sign (#). References:

質問 # 68
Which of the following permissions are set on the/tmp/directory?
- A. r-xr-X--t
- B. rwxrwS---
- C. rwSrw-rw-
- D. ------rwX
- E. rwxrwxrwt
正解：E
解説：
Explanation
The correct permissions for the /tmp directory are rwxrwxrwt, which means that the owner, group, and others have read, write, and execute permissions, and that the sticky bit is set. The sticky bit is a special permission that prevents users from deleting or renaming files that they do not own in a shared directory. The /tmp directory is used for storing temporary files that may be created by different users and processes, so it needs to be accessible and writable by all, but also protected from unauthorized deletion or modification of files. The rwxrwxrwt permissions can be set by using the chmod command with either the octal mode 1777 or the symbolic mode a+trwx. References: : [File system permissions] : [Sticky bit] : [chmod]
