In a typical cloud network, what is the primary benefit of a NAT gateway for outbound traffic?

• A. Provide inbound direct access to private instances.
• B. Enable private resources to reach the Internet while keeping private IPs hidden.
• C. Convert IPv4 addresses to IPv6.
• D. Terminate VPN connections.

Answer: (B)

The primary concept here is that a NAT gateway enables outbound Internet access for resources in a private network while keeping their private addresses hidden from the outside world. When a private instance sends a request to the Internet, the NAT gateway translates the instance’s private IP to its own public IP and forwards the traffic. When the Internet responds, the NAT gateway translates the destination back to the private IP and delivers the response to the correct instance. This means private resources can reach websites and services on the Internet without exposing their internal IP addresses. So, the best choice describes enabling private resources to reach the Internet while keeping private IPs hidden. The other options don’t fit: NAT gateways don’t provide inbound direct access to private instances, they don’t convert IPv4 to IPv6, and they don’t terminate VPN connections.
