In circuit-switched networks, what is the primary advantage?

In circuit-switched networks, a dedicated path is established between sender and receiver before any data flows, reserving a fixed amount of bandwidth for the entire session. The key benefit of this approach is that the bandwidth is guaranteed for the duration of the circuit, giving predictable performance with a steady, bounded delay and no contention from other traffic on that path. This is especially important for real-time communications like voice or video. The other options describe characteristics of packet-switched networks: best-effort delivery with variable delays happens when resources aren’t reserved and routes can queue or enqueue packets; packet-based dynamic routing is a hallmark of how data is forwarded in packet-switching; and being efficient for bursty data reflects the adaptability of packet-switched networks to traffic spikes.
