Full set: 411 questionsCorrect Answer:
C. User ID 0
Explanation
The user ID (UID) of a user that has all the privileges of a root user is 0. The root user is the superuser account that can perform any action on the system, such as changing file ownership, binding to network ports below 1024, or executing any command. The root user is identified by the UID 0, not by the name “root”, which is just a convention. It is possible to have another user account with the name “root”, but not with the same UID 0.
