CCNA: Cisco Certified Network Associate — Question 847

What is the purpose of classifying network traffic in QoS?

Answer options

• A. configures traffic-matching rules on network devices
• B. services traffic according to its class
• C. identifies the type of traffic that will receive a particular treatment
• D. writes the class identifier of a packet to a dedicated field in the packet header

Correct answer: C

Explanation

The correct answer is C because classifying network traffic helps to identify which types of traffic will receive certain levels of service treatment. Options A and D describe actions related to the implementation of QoS but do not address the classification purpose. Option B refers to the management of traffic but does not specify the importance of identifying traffic types.
