CompTIA Network+ Question C-56

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

Correct Answer: D

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.
