B.Switch your home router to use PPP encapsulation.
C.Use the ip tcp adjust-mss interface command.

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.
A.when all access to the Internet is through the IPSec tunnel
B.when there is direct Internet access via split-tunneling
C.when there is no Internet access configured through the Teleworker router
D.whenever you have IOS-Firewall (CBAC) configured
