- A.
NAT
- B.
Proxy server
- C.
Firewall
- D.
RAS
- E.
RDP
Correct Answer(s)
A. NAT
B. Proxy server
C. FirewallExplanation
NAT (Network Address Translation) allows an organization to present itself to the Internet with fewer IP addresses by translating internal private IP addresses to a single public IP address. This allows multiple devices on the internal network to share the same public IP address. A proxy server acts as an intermediary between clients and the Internet, allowing the organization to present itself with a single IP address while handling requests on behalf of the clients. A firewall filters network traffic and can also be used to hide internal IP addresses from the Internet. RAS (Remote Access Service) and RDP (Remote Desktop Protocol) are not directly related to presenting an organization to the Internet with fewer IP addresses.Rate this question:
