Which command is used to elevate privileges in Linux?

• A. sudo
• B. su
• C. elevate
• D. root

Answer: (A)

Privilege elevation in Linux is about running a command with superuser rights for that moment, without staying in a root session. The standard way to do this is with a tool that grants elevated privileges on a per-command basis: sudo. When you run a command with sudo, the system checks your permissions in the sudoers policy, prompts for your own password if needed, executes the command with root privileges, and logs the action for auditing. This approach keeps root access controlled and auditable and avoids giving you a persistent root shell. In contrast, a different method exists that switches you into a root session, requiring the root password and giving you a shell with elevated privileges until you exit. That approach is less about elevating a single command and more about staying in a privileged environment. The other options aren’t standard commands for privilege elevation: elevate isn’t a typical Linux command, and root is a user account rather than a command to elevate privileges.
