Question: What is the primary purpose of Network Address Translation (NAT)?

Options:

1. To provide a unique IP address to every device on the internet
2. To allow multiple devices on a local network to share a single public IP address
3. To encrypt data transmitted over the network
4. To increase the speed of data transmission

Correct Answer: To allow multiple devices on a local network to share a single public IP address

Solution:

NAT allows multiple devices on a local network to share a single public IP address, which helps conserve the limited number of available public IP addresses.
