Question

The technique for using one set of addresses inside a network and remapping those addresses to a different set of addresses that are seen outside the local network on the Internet is called
1. network address translation
2. address resolution
3. network address mapping
4. virtual LAN

Answer 1

Correct Answer - Option 1 : network address translation

Network address translation (NAT):

• Allow multiple devices to access the internet through a single public IP address.
• NAT is the process in which one or more local network IP address (private IP address) is translated into one more Public IP address in order to provide internet access to the local hosts.

 

Address resolution (ARP):

It converts IP address (logical address) to the MAC address(physical address).

Virtual LAN:

Virtual LAN allows a network manager to logically segment a LAN into different broadcast domains

Hence option 1is the correct answer.
