What is a primary reason for enabling Network Address Translation (NAT)?

1. To prevent viruses from entering the network

2. To translate between Internet IP addresses and private network IP addresses

3. To increase the speed of the network

4. To simplify network configuration

The correct answer is: To translate between Internet IP addresses and private network IP addresses

Enabling Network Address Translation (NAT) is primarily meant to facilitate the translation between public Internet IP addresses and private network IP addresses. In typical network scenarios, devices within a private network are assigned private IP addresses that are not routable on the Internet, allowing multiple devices to share a single public IP address. This translation process enables internal devices to communicate with external networks while maintaining the confidentiality of internal IP addresses. The use of NAT also provides the benefit of conserving the limited pool of available public IP addresses. Since many devices can access the Internet through a single public IP, NAT helps manage IP address usage efficiently. Additionally, it adds a layer of security by obscuring the internal network's structure from outside entities, as the external network only sees the public IP address rather than specific local addresses. While other options might address network concerns, they don't capture the primary function of NAT as accurately as the translation of IP addresses does.
