What is the primary purpose of a network address translation (NAT) device?

Question

Options

• ATo map private IP addresses to public IP addresses
• BTo remove malware from a network
• CTo monitor network traffic
• DTo improve network performance

• A
  88% (44)
• B
  2% (1)
• C
  6% (3)
• D
  4% (2)

Explanation

NAT allows devices on a private network (using RFC 1918 addresses like 192.168.x.x or 10.x.x.x) to communicate with the internet by translating their private IPs to one or more public IPs assigned by an ISP. This conserves the limited pool of public IPv4 addresses and provides a layer of obscurity for internal network topology. NAT does not remove malware (B), monitor traffic for analysis (C), or directly improve performance (D).
