Q10. A server with private IP address has been set up to handle requests from an outside (public) network. Which of the solutions listed below would enable its function?
A. Port Forwarding
B. Port Triggering
C. MAC Filtering
Correct Answer: A
Port forwarding :
can be used to provide access to a system within a private network from the Internet. For example, all traffic coming in port 80 can be forwarded to a web server on an internal network. Port forwarding sends traffic coming in from the Internet on a specific port to an internal system with a specific IP address.
Port triggering : uses one outgoing port as a trigger to open a specific incoming port. For example, an application might send traffic out on port 3356 and receive traffic in on port 5668. A port trigger on the router or firewall will automatically open incoming port 5668 only when traffic is sensed going out of port 3356. Port triggering opens a specific incoming port only after traffic is sent out on a specific port.
MAC filtering (Media Access Control) : Filtering refers to a security access control method where an address is assigned to each network card that's used to determine access to the network.
DHCP (Dynamic Host Configuration Protocol) : A network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers
