What is true about a recursive directory listing?
- A. It includes ownership information for the files.
- B. It includes the content of sub-directories.
- C. It includes the permissions of the directory listed.
- D. It includes details of file system internals, such as inodes.
- E. It includes a preview of content for each file in the directory.
Answer: B
Explanation:
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
NEW QUESTION # 32
Which of the following examples shows the general structure of a for loop in a shell script?
- A. foreach @{file} { echo $i
} - B. for *.txt ( echo $i )
- C. for *.txt as file => echo $file
- D. for file in *.txt do
echo $i done - E. for ls *.txt exec {} \;
Answer: D
Explanation:
Explanation
The general structure of a for loop in a shell script is as follows12:
for variable in list do commands done
The variable is the name of a loop counter or iterator that takes on the values of the items in the list. The list can be a sequence of words, numbers, filenames, or the output of a command. The commands are the body of the loop that are executed for each value of the variable. The do and done keywords mark the beginning and the end of the loop body.
The option C. for file in *.txt do echo $i done follows this structure, with the variable being file, the list being
*.txt (which matches all the files with the .txt extension in the current directory), and the command being echo
$i (which prints the value of the variable i, which is presumably set somewhere else in the script).
The other options are incorrect because:
* A. for *.txt as file => echo $file uses an invalid syntax for a for loop. The as keyword is not part of the shell script syntax, and the => symbol is not a valid operator. The correct way to write this loop would be:
for file in *.txt do echo $file done
* B. for *.txt ( echo $i ) uses an invalid syntax for a for loop. The parentheses are not part of the shell script syntax, and the loop body is missing the do and done keywords. The correct way to write this loop would be:
for i in *.txt do echo $i done
* D. for ls *.txt exec {} ; uses an invalid syntax for a for loop. The ls command is not a valid variable name, and the exec {} ; is not a valid command. This looks like a mix of a for loop and a find command.
The correct way to write this loop would be:
for file in *.txt do exec $file done
* E. foreach @{file} { echo $i } uses an invalid syntax for a for loop. The foreach keyword is not part of the shell script syntax, and the @{file} and { echo $i } are not valid expressions. This looks like a mix of a for loop and a Perl syntax. The correct way to write this loop would be:
for file in * do echo $file done

Which of the following are typical services offered by public cloud providers? (Choose three correct answers.)
- A. Infrastructure as a Service(IaaS)
- B. Platform as a Service(PaaS)
- C. Internet as a Service(IaaS)
- D. Graphics as a Service (GaaS)
- E. Software as a Service (SaaS)
Answer: A,B,E
Explanation:
Explanation
These are the three most common service models offered by public cloud providers12. They differ in the level of abstraction and control they provide to the customers.
* Platform as a Service (PaaS) is a service model where the public cloud provider offers a ready-to-use platform for developing, testing, and deploying applications. The provider manages the underlying infrastructure, such as servers, storage, network, and operating system, while the customer only needs to focus on the application code andconfiguration. Examples of PaaS include Google App Engine, IBM Cloud Foundry, and Microsoft Azure App Service12.
* Infrastructure as a Service (IaaS) is a service model where the public cloud provider offers access to fundamental compute, network, and storage resources on demand over the public Internet or through dedicated connections. The provider manages the physical hardware and virtualization layer, while the customer has full control over the configuration and management of the virtual machines, operating system, and applications. Examples of IaaS include Google Compute Engine, IBM Cloud Virtual Servers, and Microsoft Azure Virtual Machines12.
* Software as a Service (SaaS) is a service model where the public cloud provider offers ready-to-use software applications that run on the provider's infrastructure and are accessible through a web browser or a mobile app. The provider manages the entire software stack, including the infrastructure, platform, and application, while the customer only needs to pay for the usage or subscription of the service. Examples of SaaS include Google Workspace, IBM Watson, and Microsoft Office 36512.

NEW QUESTION # 40
What are the differences between a private web browser window and a regular web browser window? (Choose three.)
- A. Private web browser windows do not store cookies persistently.
- B. Private web browser windows do not keep records in the browser history.
- C. Private web browser windows do not send regular stored cookies.
- D. Private web browser windows do not support logins into websites.
- E. Private web browser windows do not allow printing or storing websites.
Answer: A,B,C
Explanation:
Explanation
A private web browser window is a mode of browsing that prevents the browser from saving your browsing history, cookies, and other site data, or information entered in forms. However, it does not prevent websites, your employer or school, or your internet service provider from tracking your online activity. The main differences between a private web browser window and a regular web browser window are:
* Private web browser windows do not store cookies persistently. Cookies are small files that websites use to store information on your device, such as your preferences, login status, or tracking data. In a regular web browser window, cookies are stored until they expire or you delete them. In a private web browser window, cookies are deleted when you close all private windows.
* Private web browser windows do not keep records in the browser history. The browser history is a list of
* web pages that you have visited in the past. In a regular web browser window, the browser history is saved and can be accessed by anyone who uses the same device or profile. In a private web browser window, the browser history is not saved and cannot be viewed by anyone.
* Private web browser windows do not send regular stored cookies. When you visit a website in a regular web browser window, the browser sends any cookies that are stored for that website. This allows the website to recognize you and provide personalized content or services. When you visit a website in a private web browser window, the browser does not send any cookies that are stored in regular windows.
This prevents the website from identifying you or linking your activity across different sessions.

Which of the following programs are web servers? (Choose two.)
- A. Dovecot
- B. Curl
- C. Postfix
- D. Apache HTTPD
- E. NGINX
Answer: D,E
Explanation:
Explanation
A web server is a program that listens for requests from web browsers and serves web pages, images, or other resources. Apache HTTPD and NGINX are two popular web servers that can run on Linux systems. They can handle multiple protocols, such as HTTP, HTTPS, FTP, and SMTP. Postfix, Curl, and Dovecot are not web servers, but they are related to web or network services. Postfix is a mail transfer agent (MTA) that can send and receive emails. Curl is a command-line tool that can transfer data from or to a web server. Dovecot is a mail delivery agent (MDA) that can store and retrieve emails from a local mailbox. References:

NEW QUESTION # 46
What is true about links in a Linux file system?
- A. Only the root user can create hard links.
- B. A symbolic link can point to a file on another file system.
- C. A symbolic link can only point to a file and not to a directory.
- D. When the target of the symbolic link is moved, the link is automatically updated.
- E. A hard link can only point to a directory and never to a file.
Answer: B
Explanation:
Explanation
A symbolic link, also known as a symlink or soft link, is a special type of file that points to another file or directory by its name. A symbolic link can point to a file or directory on the same or different file system, as long as the target is accessible. For example, you can create a symbolic link to a file on a USB drive or a network share, as long as the device is mounted or the connection is established. However, if the target of the symbolic link is moved, renamed, or deleted, the link becomes broken and does not work. To create a symbolic link, you can use the ln command with the -s or --symbolic option, followed by the target name and the link name. For example, ln -s /mnt/usb/file.txt link.txt creates a symbolic link named link.txt that points to the file.txt on the USB drive mounted at /mnt/usb.
The other options are not true about links in a Linux file system. A symbolic link can point to a directory as well as a file. A hard link, which is a direct reference to the same data as another file, can only point to a file and not a directory. A hard link cannot span across different file systems, because it depends on the inode number, which is unique within a file system. When the target of the symbolic link is moved, the link is not automatically updated, but becomes broken. Any user can create hard links, as long as they have the permission to read and write the target file and the link directory.

NEW QUESTION # 48
What is the preferred source for the installation of new applications in a Linux based operating system?
- A. A retail store
- B. A CD-ROM disk
- C. The vendor's version management system
- D. The vendor's website
- E. The distribution's package repository
Answer: E
Explanation:
Explanation
The distribution's package repository is the preferred source for the installation of new applications in a Linux based operating system. A package repository is a collection of software packages that are maintained by the distribution and can be easily installed, updated, or removed using a package manager. Package repositories offer several advantages, such as:
* They ensure compatibility and stability with the system and other packages.
* They provide security updates and bug fixes for the packages.
* They reduce the risk of malware or corrupted files.
* They simplify the dependency management and configuration of the packages.
The other sources are not preferred because they may not offer these benefits and may cause problems with the system. The vendor's version management system, the vendor's website, or a CD-ROM disk may contain packages that are not compatible with the distribution or may conflict with other packages. A retail store may not have the latest or the most suitable packages for the system. References:
