How do we know if the question should be addressed as root or as user "bob"?

Hello!

While solving mock exams, I came across questions where I have to add anacreon jobs and ‘at’ jobs, however, I’m not sure if the questions expects us to be root or user “bob”.

How can I discern if the questions want me to be root or “bob”?

Thanks,

Look at it this way. If you create jobs as bob then they will run with bob permissions. If the job you are asked to create is going to try to modify things that bob does not have the rights for, like files outside of his home directory, then the job should be created as root unless you’re told to use a specific user account.
