For Internet Protocol (IP) v6 traffic to travel on an IP v4 network, which two technologies are used

These technologies are: Dual Stack Routers, Tunneling, and NAT Protocol Translation.

Explanation:

Dual Stack Routers -  This is the process in which a router’s interface is attached with IPv4 and IPv6 addresses

Tunneling -Tunneling is used as a medium to help the different IP versions  communicate with the transit network.

NAT Protocol Translation -  This helps the IPv4 and IPv6 networks communicate with each other since they do not understand the IP addresses of each other since, they are different IP versions.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
