A corporation has a wireless network where all access points are configured in FlexConnect.
The WLC has a Data WLAN and a VoWiFi WLAN implemented where centrally-switched SSID is configured for the APs.
Which QoS configuration must be implemented for the wireless packets to maintain the marking across the wired and wireless network?

A. B. C. D.D.
The correct answer to the question is D. Trust DSCP.
Explanation:
In a wireless network, QoS (Quality of Service) is a critical feature that helps to prioritize traffic and ensure that critical traffic such as VoIP (Voice over IP) and video traffic are given priority over other traffic types. QoS configuration ensures that traffic is prioritized based on its importance, and its marking is maintained across the wired and wireless network.
In the given scenario, the access points are configured in FlexConnect mode, and two WLANs (Data and VoWiFi) are implemented. The centrally-switched SSID is configured for the APs. To ensure that the marking is maintained across the wired and wireless network, we need to configure the WLC to trust the DSCP values in the wireless packets.
DSCP (Differentiated Services Code Point) is a field in the IP header that is used to mark traffic with different levels of priority. By trusting the DSCP values, the WLC can maintain the marking across the wired and wireless network, ensuring that traffic is prioritized correctly. Therefore, the correct answer is D. Trust DSCP.
Option A, Set QoS to Platinum, is not the correct answer because QoS is not configured by setting the QoS to a specific level. Instead, QoS is configured by defining policies that prioritize traffic based on its importance.
Option B, Enable CA (Client Aware), is not the correct answer because CA is a feature that allows the AP to communicate with the client and gather information about its capabilities, but it does not directly relate to QoS configuration.
Option C, Allow WMM (Wi-Fi Multimedia), is not the correct answer because WMM is a protocol that provides QoS support for Wi-Fi networks, but it does not directly relate to QoS configuration.
