Correct answer is -> C Acceptable VoIP jitter is no more than 30 ms. This is a low tolerance. Although you can begin to see a drop in call quality at 30 ms, the detrimental effects are at 100 ms of jitter. Jitter in a VoIP system can be a quality of service (QoS) issue

Answer: D Explanation There are some recommended requirements for high-quality voice calls: + End-to-end (one-way) delay: 150 ms or less + Jitter: 30 ms or less + Packet loss: 1% or less (Reference: http://www.cisco.com/en/US/tech/tk652/tk698/technologies_tech_note09186a00800945df.shtml and CCNA Voice 640-461 Official Certification Guide)
