While viewing packet capture data, an analyst sees that one IP is sending and receiving traffic for multiple devices by modifying the IP header. Which technology makes this behavior possible?
the answer is correct, Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device.
The answer is C. tunneling.
Tunneling is a technology that allows one network to be encapsulated within another network. This means that all of the traffic from the first network is sent over the second network, as if it were part of the second network.
In the case of the question, the analyst is seeing one IP address sending and receiving traffic for multiple devices. This is possible because the traffic is being tunneled through the one IP address.
The correct answer is C. tunneling.
The behavior described, where one IP is sending and receiving traffic for multiple devices by modifying the IP header, is made possible by tunneling technology.
Tunneling involves encapsulating one network protocol within another, allowing the encapsulated protocol to traverse over a network that would not natively support it. In the context of the given scenario, tunneling is used to encapsulate traffic from multiple devices within the IP header of a single IP address.
Option D, "NAT" (Network Address Translation), involves translating IP addresses between different networks. While NAT can be used to enable multiple devices to share a single public IP address, it does not typically involve modifying IP headers to route traffic for multiple devices through a single IP address.
Modifying IP headers is exactly what NAT does... How else are you supposed to route the data? NAT replaces the RFC1989 addresses with the public IP then adds it to a state table allowing a return translation.
Tunneling encapsulates IP headers by adding a new outer IP header for public routing. It's not the same at all.
D. is correct answer
NAT (Network Address Translation ) ==> is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device.
