This is a different format of a technical question. Rather than provide you with a term and ask you to define it and describe its use, the interviewer asks you about the protocol you would use to perform a specific function on the network. There is no standard format for technical questions the interviewer will ask you. By asking you how you would perform a specific function, they are confirming that you have experience in this area and have done this in one of your past positions.

"When transmitting data between networks, I typically use routing information protocol, or RIP. This is the most efficient way to manage routing data. The protocol broadcasts its routing table to all the other routers on the network. The appropriate router then identifies itself, and the information is transmitted to it. It may take several hops between different routers for the information to reach its ultimate destination."

"Sending data between two networks is predominately done in one of two ways, TCP or UDP. TCP ensures that every packet gets to the receiving network. If there is an error in a packet or a packet is missing, that packet is resent, and an acknowledgment is sent to the sender. TCP traffic is used mostly when data is essential and every packet counts. UDP on the other hand is more fire and forget and used mostly in voice and video traffic. Since this happens in real-time, there is no benefit to making sure missed packets or errored packets get resent. Plus, this adds more overhead to the traffic that can cause network performance issues, such as higher latency or slower network."

This is a solid start, but I suggest adding a sentence or two about why you would choose this protocol.
