Which of the following devices should be placed within a DMZ?
A.
Router
B.
Firewall
C.
Mail relay
D.
Authentication server
Explanation:
A mail relay should normally be placed within a demilitarized zone (DMZ) to shield the internal network. An authentication server, due to its sensitivity, should always be placed on the internal network, never on a DMZ that is subject to compromise. Both routers and firewalls may bridge a DMZ to another network, but do not technically reside within the DMZ, network segment.
