Explanation

PAT (Port Address Translation) and NAT (Network Address Translation) are the two correct answers because both enable IP address duplication - NAT translates private IP addresses to public ones (allowing entire private networks to share a public address pool), while PAT extends this by mapping multiple private IPs to a single public IP using unique port numbers, effectively multiplying how many devices can share one address.

FAT, DAT, and CAT are not valid address translation protocols - FAT is a file system type (File Allocation Table), and DAT and CAT are simply fabricated distractors with no standard networking meaning (CAT refers to cable categories, e.g., Cat5/Cat6).

Memory tip: Think "PN = Private Network magic" - PAT and NAT are the duo that makes private IPs work on the public internet. PAT is sometimes called "NAT overload," so if you remember NAT, PAT is its turbo-charged sibling.
