Show Suggested Answer

Suggested Answer: A

The /etc/at.deny file specifies the user accounts that can NOT submit jobs via at or batch. The format of the file is a list of usernames, one on each line. Whitespace is not permitted. The superuser may always use at. If the file /etc/at.allow exists, only usernames mentioned in it are allowed to use at.If /etc/at.allow does not exist, /etc/at.deny is checked12.The at and batch commands use the files /usr/lib/cron/at.allow and /usr/lib/cron/at.deny to restrict usage on some systems3.Reference:

I think the file is called `at.deny`, but I'm not entirely sure about the path. Was it `/etc/`?
