Why should servers be placed in the DMZ?

A. So that Internet clients can access them
B. To allow access to the Internet and the internal network
C. To allow the server to access the Internet
D. To restrict the server to the Internet

B. Servers should be placed in the DMZ so they can access both the inside zone and outside zone. This will allow a server such as a web server to allow client access from the Web (outside). Rules could also be applied so that the server (for example, a database server) could allow access to data from within the internal network (inside).
