data path

• A. The software protocol used to route data
• B. The aggregated data rate across a network
• C. The encryption path used for secure communications
• D. The specific sequence of devices and physical links that a packet follows from a source to a destination

Answer: (D)

Data path is the specific sequence of devices and physical links that a packet follows from a source to a destination. It’s the actual route the data takes through the network—each hop through switches and routers and the links connecting them. Routing decisions determine which path is chosen, and the data path is the realized path that packets traverse, which is why it directly affects latency and reliability. In practice, you can observe the data path with tools like traceroute, which reveals the hop-by-hop route from sender to receiver.

The other descriptions describe related ideas but not the route itself: a routing protocol is about how paths are calculated and advertised, not the exact sequence a particular packet takes; aggregate data rate concerns how much data can pass through a network over time (throughput), not the path; an encryption path isn’t a standard term for the route data travels.
