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.

B. A network based firewall which blocks all inbound communication
C. A host-based firewall which allows all outbound communication
D. A HIDS to inspect both inbound and outbound network communication

Correct Answer: C

Explanation:
A host-based firewall is a computer running firewall software that can protect the computer itself. For example, it can prevent incoming connections to the computer and allow outbound communication only.
