CCNA: Cisco Certified Network Associate — Question 176

What is the purpose of traffic shaping?

Answer options

• A. to be a marking mechanism that identifies different flows
• B. to provide fair queuing for buffered flows
• C. to mitigate delays over slow links
• D. to limit the bandwidth that a flow can use

Correct answer: D

Explanation

The correct answer, D, is accurate because traffic shaping is designed to control the bandwidth usage of specific flows to ensure network efficiency. Option A describes a marking mechanism, which is not the primary function of traffic shaping. Option B refers to fair queuing, which is a different concept, and option C addresses delay mitigation, which is not the core intention of traffic shaping.
