Question

By default, a Linux user falls under which group?

1) staff
2) others
3) same as userid (UPG)
4) cannot be determined

Answer 1

In Linux systems, by default, a user is added to a primary group with the same name as their userid, known as the User Private Group (UPG).

Step-by-step explanation:

By default, when a user is created in a Linux system, the user is assigned to a primary group whose name is usually the same as the userid (also known as username). The correct answer to this question is 3) same as userid (UPG). The User Private Group (UPG) scheme automatically creates a group with the same name as each new user and sets that group as the user's primary group. This practice enhances security and simplifies file management for the user.
