Which of the following centralized access control mechanisms is the least appropriate for mobile workers accessing the corporate network over analog lines?
Suggested 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.

Among the options provided, TACACS (Terminal Access Controller Access-Control System) would be the least appropriate centralized access control mechanism for mobile workers accessing the corporate network over analog lines. TACACS is typically used for authentication, authorization, and accounting (AAA) in network devices. However, it requires a direct, reliable network connection, which might not be suitable for mobile workers using analog lines with potentially unreliable connections.
