Refer to the exhibit. Both routers have been configured as VoIP gateways. They must also support traditional telephony devices to connect to analog telephones. Which two configuration changes would correctly support the voice requirements?（）
A.On each router， under the dial-peer voice 1 pots configuration， add the port fa0/0 command.
B.On each router， under the dial-peer voice 1 pots configuration， add the port 1/0/0 command.
C.On each router， configure dial-peer voice 1 as a voip connection and configure dial-peer voice 2 as a pots connection.
D.Under the dial-peer voice 1 pots configuration， change the destination pattern of 1111 to 2222 on the R1 router， and 2222 to 1111 on the R2 router.
E.Under the dial-peer voice 2 voip configuration， change the destination pattern of 1111 to 2222 on the R1 router， and 2222 to 1111 on the R2 router.
F.Under the dial-peer voice 2 voip configuration， change the destination target address of 10.2.2.2 to 10.1.1.1 on the R1 router， and the destination target address of 10.1.1.1 to 10.2.2.2 on the R2 router.
A.automated alternate routing （AAR）
B.Cisco CallManager Attendant Console
C.real-time protocol （RTP）
D.Survivable Remote Site Telephony （SRST）
A.Use the command ip nbar protocol-discovery to allow identification of stateful protocols. Use the command ip nbar port-map to attach the protocols to an interface.
B.Use the command match protocol rtp to allow identification of real-time audio and video traffic. Use thecommand ip nbar port-map to extend the NBAR functionality for well-known protocols to new port numbers.
C.Use the command match protocol to allow identification of stateful protocols. Use the command ip nbar port-map to attach the protocols to an interface.
D.Configure a traffic class. Configure a traffic policy. Attach the traffic policy to an interface.
E.Configure video streaming. Configure audio streaming. Attach the codec to an interface.
A.5
B.15
C.25
D.35
E.45
F.55
A.Over leased lines，use the multilink ppp command to reduce latency and jitter，and to create Distributed Link Fragmentation and interleaving.
B.Use the service-policy command to attach a traffic flow to an interface on the router.
C.Use the ip rsvp bandwidth command to set a strict upper limit on the bandwidth NBAR uses，and toguarantee admission of any flows.
D.Use the policy-map command to define one or more QoS policies （such as shaping，policing，and so on） to apply to traffic defined by a class map.
E.Use the random-detect dscp command to modify the default minimum and maximum thresholds for the DSCP value.
F.Use the class-map command to define one or more traffic classes by specifying the criteria by which traffic is classified.
