Answer is wrong, it mentions nothing about ports, and therefore is DNAT
The answer is actually correct “PAT” translates many to one…
Port Address Translation (PAT), is an extension to network address translation (NAT) that permits multiple devices on a local area network (LAN) to be mapped to a single public IP address. The goal of PAT is to conserve IP addresses.
DNAT nat transaltes internal IP addresses to a few external addresses not a single address, that’s the difference between PAT and DNAT.
