Knowing how data moves across the network is critical to any network engineer. This will demonstrate your qualifications for this role, your expertise in setting up and managing networks, and your understanding of which transmission types are best suited for the networks you manage. If the Cisco interviewer asks follow-up questions about this topic, it indicates that they have a specific interest in this or may be experiencing problems in this area.

"There are three ways data is transferred through networks which are: simplex, half-duplex, and full-duplex. Data transferred in one direction is called simplex like for sending information to a printer or another output device. Half-duplex transmissions can send data in both directions between two devices, but not at the same time. Finally, full-duplex communication occurs in both directions simultaneously. The tradeoffs between these include complexity, performance, and cost, progressing from simplex to full-duplex."
