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
A.QoS pre-classify permits making QoS decisions based on elements from the unencrypted IP packet.
B.QoS pre-classify is required when encrypting voice.
C.QoS pre-classify is an advantage to Service Providers transporting encrypted packets.
D.QoS pre-classify is not designed for IPSec/GRE configurations.
A.when a router between the Teleworker router and the head-end VPN router is doing NAT/pNAT and does not support IPSec pass-through
B.when the Teleworker router itself is doing NAT/pNAT
C.always
D.never
Refer to the exhibit. A customer indicates their teleworkers plan to use IP phones in their home offices. The IT department has surveyed the planned teleworkers, resulting in the user groupings shown in the exhibit. To provide the highest voice quality, the best recommendations to this customer are（）.
A.Deploy all three groups with a QoS service policy, choosing the parameters for Traffic Shaping based on the average uplink speed across the three groups.
B.Teleworkers in Groups A and B should inquire with their DSL providers for subscriptions with higher uplink bandwidths.
C.Teleworkers in Group C should change their subscriptions to DSL for deployment consistency.
D.Teleworkers in Group A should upgrade their subscription to obtain static IP addresses
E.Teleworkers in Group A should inquire with their DSL providers for subscriptions with higher downlink bandwidths.
A.Teleworker devices must be accessed from the central site (server, printers).
B.IP addressing is simplified.
C.The Teleworker LAN is a transit networking for routing.
D.An Enterprise application does not function with Network Address Translation.
E.The Teleworker router is an MPLS PE node.
Refer to the exhibit. Given this deployment model and the Enterprise applications, the Teleworker Router provides which functions?（）
A.Broadband access termination
B.IPSec tunnel termination
C.H323 Signaling termination
D.Traffic Shaping
E.Compressed RTP（cRTP）for bandwidth optimization
A.QoS and IPSec should never be used together.
B.IKE/ISAKMP packets are DiffSERV codepoint CS6, so the traffic is never dropped.
C.Source IKE/ISAKMP packets off the loop-back address.
D.Classify IKE/ISAKMP packets so they are appropriately prioritized.
Refer to the exhibit. Assume Router A is configured for split tunneling. If the Internet Service provider was asked by the customer to provide a guarantee of at least 60 percent of the WAN link between Router A and Router C for encrypted traffic, what would be the best means of identifying this traffic to their QoS Service Policy?（）
A.permit esp any permit udp any eq 500 any eq 500
B.permit udp any eq isakmp any eq isakmp
C.permit ip 10.81.7.0 0.0.0.7 any
D.tcp any any eq 22
