Disable root login and require admins to use sudo with their own accounts.

Create a group of admins and give them all the same password.

Use su for all administrative tasks.

Set the root password to a complex value and share it only with admins.

An admin needs to run a series of commands as root in a script. The script is long and contains many commands. The admin wants to avoid entering the password for each command. What is the most appropriate approach?

Use su -c 'script.sh' to run the script as root.

Run the script with sudo once, so the entire script executes with root privileges.

Use sudo -i to get a root shell and then run the script.

Add each command to the sudoers file individually.

Because it has the necessary privileges to modify system-wide settings
