A network engineer is setting up a lab to practice routing protocols. The lab has no internet connectivity. The engineer wants to use addresses that will not conflict with any public addresses and are clearly for internal use. Which addressing scheme is most appropriate?

Use 169.254.0.0/16 addresses for all devices.

Use 127.0.0.0/8 for inter-router links.

Use public IP addresses from a range the company owns.

Use 10.0.0.0/8 subnets for all lab devices.

How does NAT enable internet connectivity for devices with private IPv4 addresses?

It encrypts the private address so that internet routers can forward the packet.

It creates a tunnel that bypasses the need for a public address.

It assigns a public address to each device on the LAN permanently.

It replaces the private address with a public address in the IP header as packets traverse the NAT device.

In which environment is private IPv4 addressing commonly used?

For multicast streaming on a local network

For assigning addresses to public web servers

On the public internet backbone routers

Inside a home network to connect devices like laptops, phones, and smart TVs

What is the relationship between private IPv4 addresses and NAT?

NAT eliminates the need for private addresses by providing public addresses to all devices.

NAT is required to translate private addresses to public addresses for internet communication.

NAT assigns private addresses to devices automatically.

NAT is only used for IPv6 addresses, not IPv4.

A home router uses NAT to allow multiple devices with private IP addresses to share a single public IP. A user inside the network tries to access a server on the internet. Which address does the destination server see as the source of the packets?

The private IP address of the user's device

The private IP address of the router's LAN interface

The public IP address of the home router's WAN interface

The MAC address of the user's device
