A home user's router has a public IP address on its WAN interface and assigns private IP addresses to devices on the LAN. When a device sends a packet to a website, which address does the website see as the source?

The router's private IP address

The device's private IP address

What is the primary purpose of Network Address Translation (NAT) in a network?

To assign private IP addresses to devices on a local network.

To allow multiple private IP addresses to share a single public IP address for internet communication.

To encrypt data packets traveling between private and public networks.

To block malicious traffic from entering a private network.

A company hosts a web server that must be reachable from anywhere on the internet. The server is currently assigned a private IP address. What must be done to make the server publicly accessible?

Change the server's IP to a documentation range like 203.0.113.0/24.

Assign a public IP address to the server and ensure it is reachable through the firewall.

Keep the private IP and rely on NAT to translate inbound traffic to the server.

Use a private IP and ask users to connect via a VPN.
