Which of the following centralized access control mechanisms is the least appropriate for mobile workers accessing the corporate network over analog lines?
Correct Answer: B
Call-back allows for a distant user connecting into a system to be called back at a number already listed in a database of trusted users. The disadvantage of this system is that the user must be at a fixed location whose phone number is known to the authentication server. Being mobile workers, users are accessing the system from multiple locations, making call-back inappropriate for them.
