Which of the following devices should be placed within a DMZ?

A.
Proxy server

B.
Application server

C.
Departmental server

D.
Data warehouse server

Explanation:

An application server should normally be placed within a demilitarized zone (DMZ) to shield the internal network. Data warehouse and departmental servers may contain confidential or valuable data and should always be placed on the internal network, never on a DMZ that is subject to compromise. A proxy server forms the inner boundary of the DMZ but is not placed within it.
