Select 2An 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.)
Show answer
Answer: AC
Explanation
Trust boundaries: By configuring trust boundaries, you can define which network devices should trust and prioritize the QoS markings from the VoWLAN traffic. This ensures that the QoS markings are preserved as the traffic flows through the wired network. Policy maps: Policy maps allow you to define specific QoS policies for different traffic classes. By configuring a policy map on the switch, you can ensure that the correct QoS markings are applied to the VoWLAN traffic and preserved throughout the end-to-end traffic flow. This helps prioritize the VoWLAN traffic and ensure it receives the necessary bandwidth and quality of service.
