A. Voice traffic data flow involves large volumes of large packets.
B. Because a packet loss involves a small amount of data， voice traffic is less affected by packet losses than traditional data traffic is.
C. Voice carrier stream utilizes Real-Time Transport Protocol （RTP） to carry the audio/media portion of VoIP communication.
D. Voice packets are very sensitive to delay and jitter.
E. Voice packets are encapsulated in TCP segments to allow for proper sequencing during delivery.

A.Voice VLANs are only used when connecting an IP phone and a host to distinct switch ports
B.Access ports that are configured with voice VLANs will always trust the CoS that is received from IP phones
C.Access ports that are configured with voice VLANs may or may not override the CoS value that is received from an IP phone
D.Voice VLANs are configured using the switchport voice vlan vlan-ID interface configuration command
E.Voice VLANs provide a trunking interface between an IP phone and an access port on a switch to allow traffic from multiple devices that are connected to the port
F.Enabling Voice VLAN on a switch port will automatically configure the port to trust the incoming CoS markings

A. The processing of 802.11 data and management protocols and access point capabilities is distributed  between a lightweight access point and a centralized WLAN controller.
B. LWAPP aggregates radio management forward information and sends it to a wireless LAN solution  engine.
C. LWAPP authenticates all access points in the subnet and establishes a secure communication channel  with each of them.
D. LWAPP advertises its WDS capability and participates in electing the best WDS device for the wireless  LAN

A. Router A is responsible for answering ARP requests sent to the virtual IP address.
B. If Router A becomes unavailable， Router B will forward packets sent to the virtual MAC address of Router A
C. If another router were added to this GLBP group， there would be two backup AVGs
D. Router B is in GLBP listen state.
E. Router A alternately responds to ARP requests with different virtual MAC addresses.
F. Router B will transition from blocking state to forwarding state when it becomes the AVG

A.Physically the voice network and the data network are separate
B.The voice traffic will normally be on a different IP subnet than will the data traffic
C.End user intervention is necessary to place the phone into the proper VLAN
D.The same security policy should be implemented for both voice and data traffic
E.The data VLAN must be configured as the native VLAN

A. The Aironet Desktop Utility （ADU） can be used to establish the association between the client adapter  and the access point， manage authentication to the wireless network， and enable data encryption.
B. The Aironet Desktop Utility （ADU） and the Microsoft Wireless Configuration Manager can be used at the same time to configure the wireless client adapter.
C. The Aironet Desktop Utility （ADU） can support only one wireless client adapter installed and used at a  time.
D. The Aironet Desktop Utility （ADU） profile manager feature can create and manage only one profile for the wireless client adapter.
E. When the user selects a different profile in the Aironet Desktop Utility （ADU）， the settings for the wireless client adapter are changed only after a reboot.
