What are three considerations when choosing the QoS model to deploy in a network？ （）

A. The DiffServ model requires applications to signal the network with QoS requirements.
B. The DiffServ model can be used to deliver QoS based upon IP precedence， or source and destination addresses.
C. The DiffServ model requires RSVP.
D. The best effort model is suitable for applications such as file transfer and e-mail
E. The IntServ model requires applications to signal the network with QoS requirements.
F. The IntServ model attempts to deliver a level of service based on the QoS specified by each packet

A. A Wireless Location Appliance acts as a server to one or more Cisco WCSs. It collects， stores， and passes on data from its associated Cisco WLAN controllers.
B. Before using the Web interface， the initial configuration of the Wireless Location appliance must be done using the command-line interface （CLI）.
C. The Cisco 2000， 2700， 4100， and 4400 are examples of Wireless Location Appliances.
D. The Wireless Location Appliance visually displays the location information of WLAN devices and forwards this information to third-party applications using the Simple Network Management Protocol （SNMP）.
E. The Wireless Location Appliance visually tracks up to 15，000 WLAN devices and can store this information for 90 days.

A. The SDM QoS wizard will create two real-time traffic classes to handle VoIP and voice signaling packets.
B. The SDM QoS wizard will create three real-time traffic classes to handle VoIP， voice signaling， and video packets.
C. The SDM QoS wizard will create four real-time traffic classes to handle VoIP， voice signaling， video， and video streaming packets.
D. The SDM QoS wizard will create two business-critical traffic classes to handle transactional and network management packets.
E. The SDM QoS wizard will create three business-critical traffic classes to handle transactional， network management， and routing packets.
F. The SDM QoS wizard will create four business-critical traffic classes to handle transactional， network management， routing， and best-effort packets.
