What characteristic of store-and-forward switching is important when a network supports voice over IP (VoIP)?
- It stores only the first 64 bytes of the frame.
- It is required for QoS analysis in converged networks to prioritize traffic.
- It offers a lower level of latency compared to the fragment-free switching method.
- It computes the CRC based on the first 64 bits of the frame.
Explanation: The store-and-forward frame forwarding method receives the entire frame and computes the CRC, based on the number of bits (1s) in the frame, to determine whether the received frame has an error. This method is required for QoS analysis on converged networks where frame classification for traffic prioritization is necessary.
