A VoIP system running over a wireless network link is continually being reported as choppy. Which of the following is the cause of this issue?
The correct answer is B. Latency. Choppy or degraded voice quality in VoIP is a classic symptom of high latency (and related jitter - variation in latency). VoIP encodes voice into data packets and transmits them in real time; if packets arrive late or unevenly, the audio reconstructed at the receiving end is…

Explanation
Choppy or degraded voice quality in VoIP is a classic symptom of high latency (and related jitter - variation in latency). VoIP encodes voice into data packets and transmits them in real time; if packets arrive late or unevenly, the audio reconstructed at the receiving end is choppy or broken. While interference (C) on a wireless network can contribute to retransmissions that increase latency, the direct technical cause of choppy VoIP audio is latency/jitter, not the interference itself. Frequency (A) refers to the radio band used (2.4 GHz vs 5 GHz) and alone does not cause choppiness. Encryption type (D) adds minimal overhead and would not cause noticeable voice degradation under normal conditions.
