Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 384

Which Quality of Service (QoS) mechanism is used to identify traffic flow and to use DSCP, IP Precedence values, and MPLS EXP bits to create different priority levels?

Answer options

• A. Policing
• B. Marking
• C. Queueing
• D. Classification

Correct answer: D

Explanation

The correct answer is D, Classification, as it specifically identifies and categorizes traffic flows based on different parameters such as DSCP and MPLS EXP bits. Options A (Policing), B (Marking), and C (Queueing) serve different purposes in QoS and do not primarily focus on the identification of traffic flows.
