B) VPN
C) DNS

Answer 1

The correct answer is A) NAT, which stands for Network Address Translation. NAT helps in hiding internal IP addresses and provides firewall protection, allowing one IP address to represent an entire internal network.

Step-by-step explanation:

Developed by Cisco and used by firewalls, routers, and computers that are part of a network and are connected to the Internet, Network Address Translation (NAT) provides a type of firewall protection by hiding internal IP addresses. The correct answer to this question is A) NAT.

NAT allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network. This means that only a single, unique IP address is required to represent an entire group of computers. The main purpose of NAT is to limit the number of public IP addresses an organization or company must use, for both economy and security purposes.
