You are talking to your colleague over VoIP. Which of the following best describes the variation in the delay of received packets? (Wentz QOTD)
A. Jitter
B. Latency
C. Crosstalk
D. Attenuation
Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.
My suggested answer is A. Jitter.
Wentz’s book, The Effective CISSP: Security and Risk Management, helps CISSP and CISM aspirants build a solid conceptual security model. It is a tutorial for information security and a supplement to the official study guides for the CISSP and CISM exams and an informative reference for security professionals.
