Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 363

What is used to create a QoS solution that delivers priority to voice and video traffic across a network?

Answer options

Correct answer: A

Explanation

CBWFQ (Class-Based Weighted Fair Queuing) is designed to provide priority to specific types of traffic, such as voice and video, ensuring they receive the necessary bandwidth. Traffic shaping regulates the flow of data but does not inherently prioritize traffic types. DiffServ is a framework for classifying and managing network traffic but is not a solution on its own for prioritization like CBWFQ. Traffic policing limits the bandwidth of individual traffic streams but does not guarantee priority for voice and video traffic.
