A directory contains the following three files:
texts 1.txt
texts 2.txt
texts 3.csv
Which command copies the two files ending in.txtto the/tmp/directory?
A. cp ?.txt /tmp/
B. cp *.txt /tmp/
C. cp ??.txt /tmp/
D. cp. .txt /tmp/
E. cp $?.txt /tmp/
正解:B
解説:
Explanation
The correct command to copy the two files ending in .txt to the /tmp/ directory is cp *.txt /tmp/. This command uses the wildcard character * to match any number of characters beforethe .txt extension. Therefore, it will copy both texts 1.txt and texts 2.txt to the destination directory /tmp/. The other options are incorrect because they use different wildcard characters or syntax that do not match the desired files. For example, option A uses ?? to match exactly two characters before the .txt extension, but the files have a space and a number, which are not considered as one character. Option C uses a backslash to escape the dot . before the .txt extension, but this is unnecessary and will cause the command to fail. Option D uses ? to match exactly one character before the .txt extension, but the files have more than one character. Option E uses $? to match the exit status of the previous command before the .txt extension, but this is not relevant and will cause the command to fail123 References: 1: Linux wildcards | How do wildcards work in Linux with examples? - EDUCBA 2: Wildcards in Linux explained with 10 examples | FOSS Linux 3: What are wildcard characters in Linux? - Sage-Answers

Which of the following statements is true about Free Software?
A. It must always be available free of charge.
B. It only runs on Linux.
C. It is developed by volunteers only.
D. It is only distributed as a compiled binary.
E. It may be modified by anyone using it.
正解:E
解説:
The correct statement about Free Software is that it may be modified by anyone using it. This is one of the four essential freedoms of Free Software, which are: the freedom to run the program as you wish, for any purpose; the freedom to study how the program works, and change it so it does your computing as you wish; the freedom to redistribute copies so you can help your neighbor; and the freedom to distribute copies of your modified versions to others1. Access to the source code is a precondition for these freedoms1.
The other statements are false for the following reasons:
Free Software is not developed by volunteers only. It can be developed by anyone, including individuals, companies, organizations, or communities. Some Free Software developers are paid for their work, while others do it as a hobby or for social benefit1.
Free Software does not have to be available free of charge. It can be sold or given away for any price. The term "free" refers to the users' freedom, not the price of the software1. However, Free Software users have the freedom to redistribute copies, so they can obtain the software at no charge from someone who has a copy1.
Free Software does not only run on Linux. It can run on any operating system that supports it, such as Windows, MacOS, BSD, or Android. Linux is an example of a Free Software operating system, but not the only one1.
Free Software is not only distributed as a compiled binary. It can also be distributed as source code, or both. In fact, Free Software must provide access to the source code, otherwise the users cannot study or modify the software1.

Which statements about the directory /etc/skel are correct? (Choose two.)
A. The directory contains a default set of configuration files used by the useradd command.
B. The files from the directory are copied to the home directory of the new user when starting the system.
C. The files from the directory are copied to the home directory of a new user when the account is created.
D. The personal user settings of root are stored in this directory.
E. The directory contains the global settings for the Linux system.
正解:A、C
解説:
Explanation
The /etc/skel directory is a skeleton directory that contains the default files and directories that are automatically copied to the home directory of a new user when the account is created by the useradd command12. The purpose of this directory is to provide a consistent and uniform environment for all new users and to save the system administrator's time and effort in configuring the user settings12. The /etc/skel directory can be customized by adding or removing files and directories as needed, depending on the desired default settings for the new users12.
The other options are incorrect because:
* A. The personal user settings of root are stored in this directory. This is not true, as the personal user settings of root are stored in the /root directory, which is the home directory of the root user3. The
/etc/skel directory does not affect the root user's settings, but only the settings of the new users created by the useradd command12.
* B. The files from the directory are copied to the home directory of the new user when starting the system. This is not true, as the files from the directory are copied to the home directory of the new user when the account is created, not when starting the system12. The copying process only happens once, when the useradd command is executed, and not every time the system is started12.
* E. The directory contains the global settings for the Linux system. This is not true, as the directory contains the default settings for the new users, not the global settings for theLinux system12. The global settings for the Linux system are usually stored in other directories under /etc, such as /etc/default,
/etc/sysconfig, /etc/init.d, etc4.

How is a new Linux computing instance provisioned in an laaS cloud?
A. The standard Linux installer has to be run through a remote console.
B. The installation has to be prepared in a local virtual machine which is then copied to the cloud.
C. After buying a Linux distribution, its vendor delivers it to a cloud instance.
D. A provider-specific configuration file describing the desired installation is uploaded to the cloud provider.
E. The cloud hosting organization provides a set of pre-prepared images of popular Linux distributions.
正解:E
解説:
In an Infrastructure as a Service (IaaS) cloud, the provider offers virtualized computing resources such as servers, storage, and network over the internet. The user can provision and manage these resources according to their needs. One of the common ways to provision a new Linux computing instance in an IaaS cloud is to use a pre-prepared image of a Linux distribution provided by the cloud hosting organization. An image is a snapshot of a virtual machine that contains the operating system and other software components. The user can choose from a variety of images that suit their requirements and launch a new instance from the image. This way, the user does not have to install and configure the Linux operating system from scratch, which saves time and effort. Some examples of cloud hosting organizations that provide pre-prepared images of popular Linux distributions are Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and DigitalOcean.
