Q121. Refer to the exhibit.
The exhibit shows centralized Cisco Unified Communications Manager configuration components for TEHO calls to U.S. area code 408 from the U.K. The PSTN access code for the U.K. is 9 and 001 for international calls to the U.S. What should the TEHO-US route list configuration consist of?
A. First route group should point only to the U.K. gateway. The second route group should point to the U.S. gateway.
B. First route group should be only the local route group. The second route group should point to the U.S. gateway.
C. First route group should point only to the U.S. gateway. The second route group should be the local route group.
D. The TEHO-US route list should contain only the local route group. The globalized configuration means that the appropriate gateway will be selected automatically.
E. The \\+! route pattern should point directly to the U.S. gateway.
Incorrect Answer: A, B, D The route group points to one or more gateways and can choose the gateways for call routing based on preference. The route group can serve as a trunk group by directing all calls to the primary device and then using the secondary devices when the primary is unavailable. One or more route lists can point to the same route group. Link:
Q122. Refer to the exhibit.
If an IP phone in San Jose roams to New York, which two IP phone settings will be modified by Device Mobility so that the phone can place and receive calls in New York? (Choose two.)
A. The physical locations are not different, so the configuration of the phone is not modified.
B. The physical locations are different, so the roaming-sensitive parameters of the roaming device pool are applied.
C. The device mobility groups are the same, so the Device Mobility-related settings are applied in addition to the roaming-sensitive parameters.
D. The Device Mobility information is associated with one or more device pools other than the home device pool of the phone, so one of the associated device pools is chosen based on a round-robin load-sharing algorithm.
E. The Device Mobility information is associated with the home device pool of the phone, so the phone is considered to be in its home location. Device Mobility will reconfigure the roaming-sensitive settings of the phone.
Q123. Which two actions are performed by the Call Control Discovery service after the local Cisco Unified Communications Manager loses its TCP connection with the primary and secondary Service Advertisement Framework? (Choose two.)
A. Calls are routed to the PSTN gateway after the Call Control Discovery Learned Pattern IP Reachable Duration parameter expires.
B. All learned patterns are purged from the local cache after the Call Control Discovery PSTN Failover Duration parameter expires.
C. The Service Advertisement Framework forwarder contacts all the remaining Service Advertisement Framework forwarders in the cluster.
D. All the remaining Service Advertisement Framework forwarders are notified for their learned patterns.
E. The Cisco Unified Communications Manager establishes a connection with the primary and secondary Service Advertisement Framework after the Learned Pattern IP Reachable Duration parameter expires.
F. Call Control Discovery immediately redirects all the calls to the PSTN gateway based on the learned patterns.
Q124. To preserve analog calls in an MGCP switchback event, which three commands must be configured in the MGCP fallback router? (Choose three.)
C. voice service voip
F. no h225 timeout keepalive
Incorrect Answer: B, D, E these additional command for call preservation when using MGCP fallback: voice service voip h323 no h225 timeout keepalive Reference. CCNP Voice CIPT2 642-457 Quick Reference, 2nd Edition
Q125. Which two statements regarding you configuring a traversal server and traversal client relationship are true? (Choose two.)
A. VCS supports only the H.460.18/19 protocol for H.323 traversal calls.
B. VCS supports either the Assent or the H.460.18/19 protocol for H.323 traversal calls.
C. VCS supports either the Assent or the H.460.18/19 protocol for SIP traversal calls.
D. If the Assent protocol is configured, a TCP/TLS connection is established from the traversal client to the traversal server for SIP signaling.
E. A VCS Expressway located in the public network or DMZ acts as the firewall traversal client.
Q126. Which two configurations provide the best SIP trunk redundancy with Cisco Unified Communications Manager? (Choose two.)
A. Configure all SIP trunks with DNS SRV
B. Configure all SIP trunks with Cisco Unified Border Element
C. Configure all SIP trunks to point to a SIP gateway
D. Configure SIP trunks to be members of route groups and route lists
E. Configure all SIP trunks to allow TCP ports 5060
F. Configure all SIP trunks to point to a gatekeeper through SIP to H.323 gateway
Incorrect Answer: B, C, E, F For SIP trunks, Cisco Unified Communications Manager supports up to 16 IP addresses for each DNS SRV and up to 10 IP addresses for each DNS host name. The order of the IP addresses depends on the DNS response and may be identical in each DNS query. The OPTIONS request may go to a different set of remote destinations each time if a DNS SRV record (configured on the SIP trunk) resolves to more than 16 IP addresses, or if a host name (configured on the SIP trunk) resolves to more than 10 IP addresses. Thus, the status of a SIP trunk may change because of a change in the way a DNS query gets resolved, not because of any change in the status of any of the remote destinations.
Q127. Assume that the Cisco IOS SAF Forwarder is configured correctly. Which minimum configurations on Cisco Unified Communications Manager are needed for the SAF registration to take place?
A. SAF Trunk, SAF Security Profile, SAF Forwarder, and CCD Advertising Service
B. SAF Trunk, SAF Security Profile, SAF Forwarder, and CCD Requesting Service
C. SAF Trunk, SAF Security Profile, SAF Forwarder, CCD Requesting Service, and CCD Advertising Service
D. SAF Trunk, SAF Security Profile, and SAF Forwarder
E. SAF Trunk, CCD Requesting Service, and CCD Advertising Service
Q128. The network administrator at Enterprise X is creating the guidelines for a new IPT deployment consisting of a large number of remote offices. Every user within Enterprise X is assigned a directory number of 5 digits. Which option might cause an issue in a multisite deployment?
A. Overlapping DID ranges are allocated to each site.
B. The maximum number of IP phones are in use at each remote site.
C. MoH cannot be provided for the remote sites.
D. All media streams are necessarily routed through the central office for calls to establish correctly.
Q129. Which device is needed to integrate H.320 into the Cisco video solution?
A. video gateway
B. MGCP gateway
C. H.323 gatekeeper
Incorrect Answer: A, B, D As with H.323 MCUs, H.320 gateways are provisioned in Cisco Unified CallManager as H.323 gateways, and then route patterns are configured to extend calls to these devices.
Q130. In the case of a VCS cluster, which configuration element is recommended for endpoint H.323 registration?

B. static IP addresses
