Correct answer: D
Correct answer: All (a), (b), (c) — all three routing techniques can be used in distributed systems.
Fixed routing: Uses predetermined/static paths or routing tables. Suitable for small or stable networks where routes do not change frequently.
Virtual routing: Involves logical or virtual circuits and overlay routing (for example, virtual private networks, MPLS labels, or application-level overlays). Useful for isolation, traffic engineering, or implementing logical topologies on top of physical networks.
Dynamic routing: Uses adaptive protocols (distance-vector, link-state, path-vector, etc.) to discover and update routes automatically in response to topology or link changes. Essential for scalable and resilient distributed systems.
Summary: Different distributed-system designs and network contexts call for different routing approaches. Because fixed, virtual, and dynamic routing each have valid uses, all three techniques are employed in practice.
