Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 231

While developing a real-time VoIP application on a Cisco Webex platform, users report that their voice gets chopped or parts of the conversation drop out. Which network constraint is impacting the application?

Answer options

• A. jitter
• B. capacity
• C. delay
• D. latency

Correct answer: A

Explanation

Jitter refers to the variation in packet arrival times, which can cause voice packets to arrive out of order or late, resulting in choppy audio during VoIP calls. While capacity, delay, and latency can affect voice quality, they do not specifically relate to the interruption of voice packets that jitter causes.
