Multiple choice

What is an advantage of packet-switched technology over circuit-switched technology?

  1. Packet-switched networks are less susceptible to jitter than circuit-switched networks are.

  2. Packet-switched networks can efficiently use multiple routes inside a service provider network.

  3. Packet-switched networks do not require an expensive permanent connection to each endpoint.

  4. Packet-switched networks usually experience lower latency than circuit-switched networks experience.

B Correct answer
Explanation

Packet-switched networks can use multiple routes within a provider network, allowing efficient resource utilization and redundancy. Unlike circuit-switched which requires dedicated paths, packet-switching dynamically routes packets. Option C is incorrect because packet-switching still requires connections. Option A and D are incorrect as packet-switched networks typically have more jitter and latency than circuit-switched.
