Network technologies evolved as the need to connect computers grew, and the speed, distance, and the number of nodes on the network increased. Knowing the background of some of the technologies you use and who developed them not only helps you manage the network, it shows that you have an interest in the industry and your profession beyond just day-to-day activities. This will impress the Cisco interviewer and differentiate you from the other candidates applying for this job. Additionally, since NetFlow was developed by Cisco, you are expected to know this.

"NetFlow is an open but proprietary network protocol created by Cisco Systems. It collects active IP network traffic as it flows in or out of an interface. Data collected by NetFlow is analyzed to understand network traffic flow and the volume of data transiting the network. I use NetFlow protocol as a network traffic analyzer to determine the point of origin of data packets, their destination, the overall volume on the network, and the paths the data takes."
