Question

What variation of network address translation (NAT) allows multiple inside local addresses to share a single inside global address?

a) Dynamic NAT
b) Static NAT
c) PAT (Port Address Translation)
d) NAT64

Answer 1

PAT (Port Address Translation) is the variation of network address translation (NAT) that allows multiple inside local addresses to share a single inside global address.

Step-by-step explanation:

The variation of network address translation (NAT) that allows multiple inside local addresses to share a single inside global address is c) PAT (Port Address Translation). This technique, also known as NAT overload, works by assigning a unique port number to each session (or internal host) traffic, enabling multiple devices to be mapped to a single public IP address but with different port numbers. It's widely used in small office/home office (SOHO) environments where many devices need to access the internet with a limited number of public IP addresses.

The variation of network address translation (NAT) that allows multiple inside local addresses to share a single inside global address is PAT (Port Address Translation).

PAT works by assigning unique port numbers to each inside local address, allowing multiple devices to share the same inside global address. This allows for the conservation of IPv4 addresses and enables multiple connections on a single IP address.
