A.requires access lists to identify the voice traffic
B.can allow traffic from a device without 802.1X authentication, by MAC address
C.can allow traffic from Cisco IP phones by listening to their CDP advertisements
D.allows all packets marked with a ToS of 5 to bypass authentication

A.Upgrade your residential broadband service to at least 768kbps uplink.
B.Switch your home router to use PPP encapsulation.
C.Use the ip tcp adjust-mss interface command.
D.Employ QoS techniques to drop large data packets.
E.Use traffic shaping to interrupt large data packets.
Refer to the exhibit. Given the CPE deployment model, the Enterprise applications shown, and the functions being provided as designated, the appropriate product choice is（）.
A.Cisco PIX 501 Firewall
B.Cisco 831 router
C.Cisco 837 router
D.Cisco VPN3002 Hardware Client
E.Cisco ubr925 cable modem
F.Cisco SW VPN Client
A.TCP packet sizes can be optimized by the router so there is no IPSec or AAL5 padding.
B.The local loop is a dedicated connection for a single subscriber to the DSLAM.
C.Access to the WAN media uses a poll/response mechanism so no two subscribers transmit at the same time.
D.There are no distance requirements from the Central Office (CO).
Refer to the exhibit. Asymmetric broadband service with significantly greater downstream bandwidth is recommended for Teleworker deployment. Which reason is the most accurate?（）
A.Most ISPs do not provide QoS for residential broadband. Asymmetric bandwidth reduces the chance of downstream congestion when traffic from Internet sites competes for bandwidth with IP voice traffic.
B.Additional downstream bandwidth compensates for insufficient upstream bandwidth. The aggregate bandwidth provides the same result.
C.The additional bandwidth is needed to access more than one site. Most HTTP traffic is downstream.
D.The additional downstream bandwidth allows the Enterprise VPN device to send the IP voice packets much faster, allowing them to reach the Teleworker network with less latency.
