NAT stands for?

• A. Dynamic address translation
• B. Network Access Token
• C. Network Address Translation
• D. Name address translation

Answer: (C)

Network Address Translation is the process of modifying IP address information in packet headers as traffic passes through a router, typically mapping private internal addresses to a public address (and back for responses). This lets many devices on a private network share a limited number of public IPs when communicating with the Internet, often with a translation table keeping track of each connection. That’s why this acronym corresponds to the standard term NAT.

The other phrases aren’t the standard terminology for what NAT does—dynamic address translation isn’t the common name for the mechanism, a Network Access Token refers to authentication, and Name address translation isn’t a recognized term in networking.
