ITPEC IP April 2022 Question 33
ITPEC IP April 2022 — Question 33 of 100
NAT converts between private IP addresses inside a LAN and a global IP address used on the Internet. Private addresses are not routed across the public Internet. A NAT-capable router rewrites address information as traffic crosses the network boundary, allowing internal devices to communicate externally through public addressing.
Answer (b)
Why not others:
- a MAC address identifies a network interface on a local link and is not the public counterpart translated by NAT
- host names are mapped to IP addresses by DNS, not NAT
Key rule: NAT translates IP addressing across private and public network boundaries; DNS resolves names, and local link protocols handle MAC addresses.
