QUESTION 11
Given: Use the exhibit as a reference. ABC Company has a WLAN controller with 10 controller-based APs; the Voice SSID is configured for centralized data forwarding. Each AP is connected to an access port on a layer-2 Ethernet switch. Each layer-2 switch is uplinked to a single layer-3 core Ethernet switch. The WLAN controller is connected directly to the layer-3 core Ethernet switch. Layer-3 tunnels are created between all controller-based APs and the WLAN controller. A voice server is connected to the layer-3 Ethernet switch. When a voice-enabled QoS STA sends an IP data packet to a voice server in this scenario, the DSCP value carried in the STA’s IP data packet gets mapped to what and by which device?
