AWS, JavaScript, React - Deploy Web Apps on the Cloud - Introduction to User Accounts

The video tutorial explains the use of the root user account in Linux, highlighting its extensive administrative privileges and potential risks. It discusses the dangers of using the root account, such as security vulnerabilities and accidental system damage. To mitigate these risks, the tutorial introduces the concept of creating multiple user accounts with varying permissions and the use of user groups. It explains the pseudo and SU commands, which allow non-root users to perform administrative tasks. The video concludes with a preview of the next lecture, which will provide a hands-on guide to creating non-root accounts.

What is the primary role of the root user account in a Linux system?

• To provide limited access to system files

• To manage user accounts with restricted privileges

• To serve as the default administrative account with full privileges

• To act as a backup user account

Which of the following actions can be performed by the root account?

• Create and delete non-root accounts

• Modify hardware settings directly

• Install software without permissions

• Access the internet without restrictions

How can a security vulnerability in an application affect the system?

• It can grant root privileges to malicious scripts

• It can slow down the system performance

• It can automatically update the system

• It can improve system security

What is the purpose of creating user groups in Linux?

• To enhance the graphical user interface

• To assign and manage similar access rights to multiple users

• To limit the number of users on a system

• To increase the system's processing speed

What is the difference between the pseudo and SU commands?

• Pseudo is a graphical tool, while SU is a command-line tool

• Pseudo grants full root privileges, while SU grants limited access

• Pseudo is used for file management, while SU is for user management

• Pseudo grants partial administrative privileges, while SU grants full root privileges
