D.The phone and PC behind Router A will not be able to connect to a host on 192.168.1.0/24
A.CiscoWorks VPN Manager
B.Easy VPN client mode
C.deploy Linksys routers with menu driven configuration
D.disable 802.1x and Auth Proxy on the Teleworker router
A.most widely deployed by service providers
B.provides asymmetrical bandwidth, including high speed downlink
C.data rate is affected by distance to the Central Office
D.provides the furthest reach at T1 speeds
E.supports connection of two routers without the use of a DSL access concentrator
A.RSVP is a required configuration to support conference calls without voice packet loss.
B.The QoS configuration on the 831 router must always provision sufficient bandwidth for two RTP streams.
C.Call admission control is an issue only when using hardware DSP resources.
D.When using the conference call features on a 7960 IP phone, only one RTP stream is present regardless of how many extensions are on the conference.
Refer to the exhibit. With an IPSec tunnel established between remote Router A and head-end router B, with Compressed Real-Time Protocol (cRTP) configured on the serial interface of Router A, what impact will the cRTP configuration have on the Voice over IP packets flowing through the IPSec tunnel from a Cisco 7960 IP phone?（）
A.Twenty bytes of header will be replaced with five bytes.
B.If the IPSec transform set includes Authentication Header, the receiving IPSec peer will discard the packets.
C.The IPSec packets will be dropped by Router A's compression logic.
D.The voice packets will not be compressed.
A.IPM should not be run on a production network.
B.IPM helps verify if a Service Provider is meeting the Service Level Agreement.
C.IPM contains a database that can store data on latency, jitter, and drops of voice packets over a period of weeks or months.
D.The QoS service policy should contain an allocation of sufficient bandwidth in the priority queue (LLQ) for both the SAA probe simulating a voice call and the voice call. If not, voice quality will suffer.

E.domain-name cisco.com
F.option 150 ip 10.3.3.3
A.A voice packet is sent via multiple fixed-length cells; a portion of the last cell is padding, requiring more bandwidth.
B.ADSL typically uses PPPoE encapsulation, which adds additional overhead to each voice packet.
C.A voice packet is sent via multiple fixed-length cells; each cell has about 10% Layer-2 header overhead.
D.IPSec requires additional overhead for the header and hash.

B.Configure pNAT to ensure Voice over IP packets are properly translated.
C.Configure IOS firewall to permit RTP port numbers through the firewall via VPN.
D.Configure Access Control Lists to allow Voice over IP traffic to bypass Auth Proxy checking.
