A company has a web server with a private IP address of 10.0.0.10. They want to make this server accessible from the internet using a public IP address of 203.0.113.5. The administrator needs to configure the edge router to translate traffic destined to the public IP to the private IP. Which NAT configuration should be applied?

Dynamic NAT with a pool of public addresses

Which statement correctly describes a key difference between IPv4 and IPv6 addressing?

IPv4 addresses are expressed in hexadecimal, while IPv6 addresses are expressed in dotted decimal.

IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses.

IPv4 uses 128-bit addresses, while IPv6 uses 32-bit addresses.

IPv4 addresses are always public, while IPv6 addresses are always private.

What is the purpose of configuring port forwarding in NAT?

To automatically assign private IP addresses to devices on the internal network.

To allow external hosts to reach a specific internal service by mapping a public IP/port to a private IP/port.

To encrypt traffic between the internal network and the internet.

To block all inbound traffic from the internet.
