• Question 208:

  While troubleshooting a network, a VoIP systems engineer discovers a significant inconsistency in the amount of time required for data to reach its destination and return. Which of the following terms BEST describes this issue?

  A. Bandwidth

  B. Latency

  C. Jitter

  D. Throughput

  Correct Answer: C

  Jitter refers to the variation in packet arrival time at the receiving end. It can result in the loss of data packets or poor voice quality in VoIP systems due to the irregular delivery of data. Jitter is a significant concern for real-time applications such as VoIP, video conferencing, and online gaming, as it can cause delays and disruptions in communication.

  Bandwidth (option A) refers to the capacity of a network to transmit data. Latency (option B) is the time delay between the sending of a data packet and the receiving of a response. Throughput (option D) refers to the actual amount of data that is successfully transmitted over a communication channel. While all these factors are important in network performance, the inconsistency described in the scenario points to the issue of jitter.
