A technician is installing a surveillance system for a home network. The technician is unsure which ports need
to be opened to allow remote access to the system. Which of the following should the technician perform?

A.
Disable the network based firewall

B.
Implicit deny all traffic on network

C.
Configure a VLAN on Layer 2 switch

D.
Add the system to the DMZ

Explanation:
By putting the system in the DMZ (demilitarized zone) we increase the security, as the system should be
opened for remote access.A DMZ is a computer host or small network inserted as a “neutral zone” between a company’s private network
and the outside public network. It prevents outside users from getting direct access to a server that has
company data. A DMZ often contains servers that should be accessible from the public Internet.
