Q81. Refer to the exhibit.
The HQ site uses area code 650. The BR1 site uses area code 408. The long distance national code for PSTN dialing is 1. To make a long distance national call, an HQ or BR1 user dials access code 9, followed by 1, and then the 10-digit number. Both sites use MGCP gateways. AAR must use globalized call routing using a single route pattern. Assume that all outgoing PSTN numbers are localized at the egress gateway as shown in the exhibit.
What should the AAR group prefix be?
A. 9
B. 91
C. none
D. +
E. +1
Answer: C
Q82. Scenario There are two call control systems in this item. The Cisco UCM is controlling the DX650, the Cisco Jabber for Windows Client, and the 7965 and 9971 Video IP Phones. The Cisco VCS and TMS control the Cisco TelePresence Conductor, the Cisco TelePresence MCU, and the Cisco Jabber TelePresence for Windows.
Use the exhibits to answer the following questions.
DNS Servers
Device Pool
Expressway
ILS
Locations
MRA
Speed Dial
SIP Trunk
The intercluster URI call routing no longer allows calls between sites. What is the reason why this would happen? (Choose two)
A. Wrong SIP domain configured.
B. User is not associated with the device.
C. IP or DNS name resolution issue.
D. No SIP route patterns for cisco.lab exist.
Answer: C,D
Q83. If the device pool in the phone record does not match the device pools in the matching subnet, what will the system consider the phone to be?
A. roaming
B. unregistered
C. unknown

Answer: A
Q84. Refer to the exhibit.
How many calls can be placed to Cluster B?
A. three G.729 calls
B. one G.711 call
C. one G.711 and three G.729 calls
D. There is no limit for incoming calls to Cluster B. Outgoing calls are limited to one G.711 and three G.729 calls.
Answer: A
Q85. Which two statements about remote survivability are true? (Choose two.)
A. SRST supports more Cisco IP Phones than Cisco Unified Communications Manager Express in SRST mode.
B. Cisco Unified Communications Manager Express in SRST mode supports more Cisco IP Phones than SRST.
C. MGCP fallback is required for ISDN call preservation.
D. MGCP fallback functions with SRST.
Answer: A,D
Q86. What command is used to map internal extensions to the corresponding E.164 PSTN number when using Cisco Unified Communications Manager Express in SRST mode?
A. ephone-dn
B. dialplan-pattern
C. number
D. number-e.164
E. ephone-transnumber
Answer: B
Q87. What is the difference between an H.323 gateway and a SIP gateway?
A. An H.323 gateway requires that dial peers be configured before PSTN calls can be placed and received. The SIP gateway requires no dial peers.
B. The H.323 gateway can be added in Cisco Unified Communications Manager under gateway type as H.323 Gateway. The SIP gateway can connect to Cisco Unified Communications Manager only through a SIP trunk.
C. A SIP gateway requires a call agent for PSTN calls to be placed and received. An H.323 gateway does not require a call agent for PSTN calls to be placed and received.
D. An H.323 gateway can register with Cisco Unified Communications Manager. A SIP gateway will show status of "Unknown".
E. The H.323 gateway must be configured in Cisco Unified Communications Manager using a valid IP address on the gateway. The SIP gateway must be configured in Cisco Unified Communications Manager using the domain name.
Answer: B
