The statement that is false when a packet is being compared to an access list is:
"Until all lines have been analyzed, the comparison is not over."
This statement is misleading because, in reality, once a packet matches a condition on a line of the access list, the action (permit or deny) is taken immediately, and no further comparisons are made. Therefore, it's not accurate to say that the comparison isn't over until all lines have been analyzed, as processing can stop early once a matching condition is found.
