Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 6

What is a characteristic of video traffic that governs QoS requirements for video?

Answer options

• A. Video is typically variable bit rate.
• B. Voice and video traffic are different, but they have the same QoS requirements.
• C. Video is typically constant bit rate.
• D. Voice and video traffic are the same, so they have the same QoS requirements.

Correct answer: A

Explanation

The correct answer is A because video traffic usually varies in bit rate, which affects its QoS requirements. Options B, C, and D are incorrect as they either misrepresent the nature of video traffic or incorrectly equate the QoS needs of voice and video, which are distinct.
