Which configuration takes precedence if the two configurations are different? A.    The configuration in the global configuration always takes precedence over the interface configuration.B.    The voice gateway parses the configuration from top to bottom and will use the first isdn switch- type entry.C.    The voice gateway will use the isdn switch-type command that matches the ISDN switch that is connected to the T1 controller.D.    The configuration in the T1 controller portion of the Cisco IOS configuration takes precedence over the isdn switch-type command in the global configuration.E.    The configuration under the ISDN signaling channel takes precedence over the isdn switch-type command in the global configuration. Answer: E QUESTION 223What is the reason that a call succeeds when COR is applied to the incoming dial peer and is equal to or greater than the COR settings that are applied to the outgoing dial peer? A.    The COR list for incoming calls on the incoming dial peer is a superset of COR lists for outgoing calls on the outgoing dial peer.B.    COR lists for incoming calls on the incoming dial peer are not a superset of COR lists for outgoing calls on the outgoing dial peer.C.    The outgoing dial peer, by default, has the lowest priority.D.    The incoming dial peer, by default, has the highest COR priority when no COR is applied. Answer: A QUESTION 224Calls are failing to reach the E1 PRI circuit on the PSTN gateway. Which command would be useful in determining if the dial peers are configured properly? A.    debug voice dial-peerB.    debug isdn q921C.    ccapi inoutD.    show controller e1 0/0/0E.    debug voice circuit Answer: A QUESTION 225Refer to the exhibit. When an inbound PSTN call from 4087071222 arrives at the ISDN port that is shown in the exhibit, which dial peer will be matched for the inbound leg?  A.    Dial-peer 123, because incoming called-number takes precedence over answer-address.B.    Dial-peer 2123, because answer-address takes precedence over incoming called-number.C.    The matching inbound dial peer will be selected at random.D.    Although dial-peer 123 takes precedence, there is no direct-inward-dial that is configured, therefore 2123 will be selected.E.    Although dial-peer 123 takes precedence, there is no port that is configured under dial-peer 123, therefore dial-peer 2123 will be selected. Answer: A QUESTION 226Which four interworking call flows are associated with a Cisco Unified Border Element using media flow-around? (Choose four.) A.    H.323 fast start to H.323 fast startB.    H.323 slow start to SIP delayed offerC.    SIP early offer to SIP delayed offerD.    SIP delayed offer to SIP delayed offerE.    H.323 fast start to H.323 slow startF.    SIP early offer to H.323 fast start Answer: ACDE QUESTION 227Which three methodologies are specific types of QoS used on a 512-kb/s point-to-point IP WAN link?

A.    The device that cannot recognize DSCP will use best effort to forward the packet.B.    The device that does not recognize DSCP will use 110 as the CoS value and forward the packet with a CoS of 6.C.    The first device in the network that does not recognize DSCP will use 110 as the CoS value and will replace the DSCP value with a CoS of 6 and forward the packet.D.    The devices in the network that do not recognize DSCP will use the three high-order DSCP bits as the CoS setting, resulting in a CoS value of 5.
