I agree with you. The question never says that you must change owner group.

Exactly. Perhaps it says with file named admin but then you never know. Will stick with adolfoale's answer for now.

"to /var/tmp name admin" cp -p /etc/fstab /var/tmp/admin chown user1 /var/tmp/admin chmod 700 /var/tmp/admin this way user1 as owner, user2 is considered as 'other' without access permission.

I have many doubts in this question . the question does not say for making owner to admin. and I think question says admin and user1 give r w x permission, after seeing this question.

Why are the setfacl changes being made to the /var/tmp/fstab folder? Isn't it just asking to change the permissions on /var/tmp?
