Exam A
QUESTION 1
Where does an IP phone obtain the extension number and speed-dial settings from?
A. the settings that are configured on the physical phone
B. the registration file that the phone receives from the Cisco Unified Communications Manager
C. the device and line configuration in Cisco Unified Communications Manager, during the registration process
D. the default device profile that is configured in Cisco Unified Communications, Manager
Correct Answer: B Section: (none) Explanation
Explanation/Reference:
when we configure IP phone profile in CUCM that time we also configure extension number and speed dial
as per requirement.
when IP reachability gets establish between IP phone and CUCM then phone will download config file from
CUCM during initial registration process.

QUESTION 4
Refer to the SDI trace in the exhibit A PSTN call arrived at the MGCP gateway that is shown in the SDI trace. If the caller ID that is displayed on the IP phone is 087071 222 and the HQ_clng__pty_CSS contains the HQ_cing_pty_Pt partition, which exhibit shows the correct gateway digit manipulation”?
A.
C.

QUESTION 7
Refer to the exhibit. When a Cisco IP Communicator phone roams from San Jose (SJ) to RTP, the Cisco IPCommunicator physical location and the device mobility group change from SJ to RTP All route patterns are assigned a route list that points to the local route group All device pools are configured to use the local route group Which statement is true when the roaming phone places an AAR call?

A. Since globalized call routing is not configured, then the SJ gateway will be used in this case
B. The phone will use the AAR CSS that contains the SJ_PSTN partition. The call will egress at the SJ gateway
C. The phone will use the AAR CSS that contains the RTP_PSTN partition. The call will egress at the SJ gateway
D. The phone will use the AAR CSS that contains the SJ_PSTN partition. The call will egress at the RTP gateway.
E. The phone will use the AAR CSS that contains the RTP_PSTN partition The call will egress at the RTP gateway
Correct Answer: D Section: (none) Explanation
Explanation/Reference:
Cisco Unified Communications Manager Version 7.0 introduced the Local Route Group feature. When using local route groups, gateway selection is totally independent of the matched route pattern and referenced route list and routegroup. The use of the Local Route Group feature makes no changes regarding roaming-sensitive settings. The application of these settings always makes sense when roaming between sites. The settings have no influence to the gateway selection and the dial rules that a user must follow. However, the dial plan-related part of Device Mobility changes substantially withthe new dial plan concept, This concept allows a roaming user to follow the home dial rules for external calls but use the local gateway of the roaming site
In this case, When the device mobility group is not the same for San Jose and RTP, the Device Mobility related settings are not applied. The phone device keeps its San Jose-specific configuration Despite the San Jose-specific configuration on the phone, the PSTN calls that originate from the roaming phone are routed via the local PSTN gateway (RTP GW) and are based on the route list and device pool local route group settings. The San Jose-specific dial plan is used. Also, AAR remains configured with the San Jose-specific configuration, but if the San Jose dial plan and San Jose AAR CSS permit and if the AAR group contains the prefix that can be applied in RTP, then AAR can work
QUESTION 8

QUESTION 11
MOH has been configured to run from flash at the BR1 site. The HQ phones and MOH server are placed in the Default region through the Default device pool. The BR1 phones are placed in the BR1 region through the BR1 device pool. The region configuration between Default and BR1 only permits G.729 codec.
When an IP phone user at the HQ site places a BR1 caller on hold, the BR1 caller hears tone on hold. Which of the following can cause this issue?

E01 (exhibit):

E02 (exhibit): E03 (exhibit): E04 (exhibit): E05 (exhibit): E06 (exhibit): E07 (exhibit): E09 (exhibit):

A. Multicast routing is not enabled on the BR1 router.
B. The command ip pim sparse-dense-modeis missing from interface VLAN 120 at the SRST router in BR1.
C. The MOH server is unable to stream MOH using G.711 codec because of the regions configuration.
D. The command route 10.1.120.1 must be added to the multicast moh 239.1.1.1 port 16384command at the SRST router in BR1.
E. The Max Hopsis too small in the MOH configuration
Correct Answer: B Section: (none) Explanation
Explanation/Reference:
The router runs IP Multicast routing and IP PIM sparse-dense mode on any physical interface that must
participate in multicast (PIM is in either sparse or dense mode,
but the interface can be configured to forward sparse mode, dense mode, or both).
In this case, interface VLAN120 missing the command ip pim sparse-dense-mode.

QUESTION 16
Assume a centralized Cisco Unified Communications Manager topology with the headquarters at RTP and remote located at the UK. All route patterns are assigned a route list that contains a route group pointing to the local gateway. RTP route patterns use the RTP gateway, and UK route patterns use the UK. gateway.

A. The call will match the U K_ Emergency route pattern partition and will egress at the RTP gateway.
B. The call will match the U K_ Emergency route pattern partition and will egress at the UK. gateway.
C. The call will match the RTP_ Emergency route pattern partition and will egress at the RTP gateway
D. The call will match the RTP_ Emergency route pattern partition and will egress at the UK gateway.
E. The call will fail
Correct Answer: A Section: (none) Explanation
Explanation/Reference:
The call will match the U K_ Emergency route pattern partition and will egress at the RTP gateway Exhibit clearly explains the call will match UK emergency partition hence call will flow via RTP gateway
QUESTION 17
Which issue would cause an MGCP gateway to fail to register with Cisco Unified Communications Manager?
A. missing the configuration command isdn bind-13 ccm-manager under the ISDN interface
B. mismatched domain name on the MGCP gateway and Cisco Unified Communications Manager gateway configuration C. misconfigured route group in Cisco Unified Communications Manager
