CWNP CWDP-302 問題集

質問 1：
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?
A. The DSCP value is mapped to an IEEE 802.1p (802.1D-2004) UP value by the access point.
B. The DSCP value is mapped to an IEEE 802.1Q priority tag value by the WLAN controller.
C. The DSCP value is mapped to the DSCP value in the encapsulating IP header by the layer-3 switch.
D. The DSCP value is mapped to an IEEE 802.1Q VLAN tag by the access point.
正解：B

質問 5：
One of your customers plans on providing wireless coverage to a warehouse facility. After performing an initial walkthrough, you collect the following information:
* The central part of the warehouse is between 400 and 600 feet (122 to 183 meters) from the warehouse switches mounted on the walls.
* The warehouse storage is composed of metallic racks with varying inventory levels and contents, from electronics and plastic toys to food pallets and juice bottles.
* Workers need basic data coverage from their working location, and are not highly mobile. They usually work from one single aisle, and their laptop is on a cart with wheels.
What would be your one recommendation to provide coverage to the central area of the warehouse?
A. Install APs for client access in the central area and use a mesh backhaul link to connect to the DS.
B. Equip workers laptops with a directional antenna and install APs less than 328 feet (100m) away from the switch.
C. In this case, extend the cable length just beyond 328 feet (100 m) and position APs as close as possible to the central area of the warehouse.
D. Position APs along the walls, and equip the APs with Yagi antennas to cover the central area.
正解：A
