CCNA: Cisco Certified Network Associate — Question 761

What is a purpose of traffic shaping?

Answer options

• A. It enables policy-based routing.
• B. It enables dynamic flow identification.
• C. It provides best-effort service.
• D. It limits bandwidth usage.

Correct answer: D

Explanation

The correct answer, D, is right because traffic shaping is specifically designed to limit bandwidth usage by controlling the amount of data sent over the network. Options A, B, and C do not accurately describe the primary function of traffic shaping, as they relate to routing policies or service types rather than bandwidth management.
