Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 268

An engineer set up a VoWLAN with QoS on the WLC and a class map on the switch, but the markings are not being preserved correctly in the end-to-end traffic flow. Which two configurations on the wired network ensure end-to-end QoS? (Choose two.)

Answer options

• A. trust boundaries
• B. access lists
• C. policy maps
• D. QoS licenses
• E. NetFlow

Correct answer: A, C

Explanation

The correct answers, A and C, are essential for ensuring that QoS markings are preserved. Trust boundaries define where the trust in QoS markings begins and ends, while policy maps are used to apply QoS policies to traffic. Options B, D, and E do not directly influence the preservation of QoS markings in the same way.
