Selected Answer: B
latency because it's a consistent delay in voip. if it was all over the place/inconsistent it would be jitter

Selected Answer: B
Latency is caused by Jitter. If they're asking what was causing the latency you'd respond with Jitter.

This is completely false. Jitter doesn't cause latency and you can have latency without having jitter. Jitter is simply a difference between two latency events. If you ping and get 20ms/21ms/19ms this is just latency if you get 20ms/300ms/20ms this is jitter, you can have high latency without jitter and jitter with low latency. The answer is indeed B, though

No, its latency that degrades call quality - dropped calls, distortion and delays and even echos

Latency is the time travelled source to destination which will explain the delay. Jitter is the inconsistency in latency which is not mentioned in this scenario which is why the answer is B
