A.IP phone extensions for teleworkers must be chosen carefully so not to duplicate campus phone extensions.
B.More security exposure exists due to lack of support for Intrusion Detection System and URL filtering for teleworker originated traffic.
C.Compressed RTP and IPSec are not compatible and result in no bandwidth savings.
D.Broadband modems must support Quality of Service for adequate voice quality.

Refer to the exhibit. The Linksys router in the diagram is performing pNAT (port network address translation). What hash algorithm should you choose and why?（）
A.Use hash MD5 to ensure that IKE works through NAT.
B.Use ah-sha-hmac, as it does not check the integrity of the IP header. The IP header will change due to NAT.
C.Use 3DES, as it will encrypt the IPSec header IP addresses and bypass addressing issues.
D.Use esp-sha-hmac, as it does not check the integrity of the IP header. The IP header will change due to NAT.
Refer to the exhibit. A Teleworker router is deployed behind a broadband Cable service. If the Teleworker router has the configuration shown, what will be the DNS server selected for DHCP clients on the LAN-side interface?（）
A.DHCP clients will automatically default to the DNS root servers for all DNS requests in the IP stacks locally.
B.DHCP clients will use the IP set in the option 150 command.
C.DHCP clients will use the DNS entry assigned by the ISP.
D.DHCP clients will have no DNS server set in the IP stack.
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
E.allows all IP voice packets to bypass authentication via stateful inspection
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.
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
