Q101. Refer to the exhibit.
Assuming the regions configuration to BR only permits G.729 codec, how many calls are allowed for the BR location?
A. Total of four calls; two incoming and two outgoing.
B. Total of two calls in either direction.
C. Total of four calls to the BR location. Outgoing calls are not impacted by the location configuration.
D. Total of four calls in either direction.
E. Two outgoing calls. Incoming calls are unlimited.
Answer: D
Explanation:
Incorrect Answer: A, B, C, E In performing location bandwidth calculations for purposes of call admission control, Cisco Unified Communications Manager assumes that each G.729 call stream consumes 24 kb/s amount of bandwidth Link:

Q102. In a cluster-wide deployment, what is the maximum number of Service Advertisement Framework forwarders to which the Cisco Unified Communications Manager can connect?
A. 1
B. 2
C. 3
D. 4
E. 6
F. as many as are configured
Answer: B
Q103. Which statement is true when considering a Cisco VoIP environment for regional configuration?
A. G.711 requires 128K of bandwidth per call.
B. G.729 requires 24K of bandwidth per call.
C. The default codec does not matter if you have defined a hardware MTP in your Cisco Unified Communications Manager environment.
D. To deploy a Cisco H.323 gatekeeper, you must configure MTP resources on the gatekeeper and only use G.711 between regions.
Answer: C
Q104. You recently implemented call redundancy at a new remote site, and users report that calls are dropped when the remote site supposedly is in SRST. Which two actions must you take to troubleshoot the problem? (Choose two.)
A. Confirm that SRST is configured on the voice gateway.
B. Confirm that the site has an SRST reference that is correctly associated with the Cisco Unified Communications Manager group.
C. Confirm that a calling search space is assigned to the voice gateway in Cisco Unified Communications Manager.
D. Confirm that the site devices are associated with a Cisco Unified Communications Manager group and that four Cisco Unified Communications Manager servers are available.
E. Check the Region settings in Cisco Unified Communications Manager.
F. Restart Cisco Unified Communications Manager services to confirm that the server is working correctly.
Answer: A,B
Q105. What is a prerequisite of AAR deployment?
A. You must have a single distributed call processing deployment.
B. Calls must be manually rerouted through the PSTN or other networks when Cisco Unified Communications Manager blocks a call due to insufficient location bandwidth.
C. Calls must be automatically rerouted through the PSTN or other networks when Cisco Unified Communications Manager blocks a call due to insufficient location bandwidth.
D. Clustering must be implemented over the WAN.
E. You must have a centralized call processing deployment.
Answer: E
Q106. Which two options are valid service parameter settings that are used to set up proper video QoS behavior across the Cisco Unified Communications Manager infrastructure? (Choose two.)
A. DSCP for Video Calls when RSVP Fails
B. Default Intraregion Min Video Call Bit Rate (Includes Audio)
C. Default Interregion Max Video Call Bit Rate (Includes Audio)
D. DSCP for Video Signaling
E. DSCP for Video Signaling when RSVP Fails
Answer: A,C
Q107. The administrator at Company X is trying to set up Extension Mobility and has done these steps:
-Set up end users accounts for the users who need to roam
-Set up a device profile for the type of phones users will be allowed to log in Users have reported to the administrator that they are unable to log in to the phones
designated for Extension Mobility. Which two options are the two reasons for this issue? (Choose two.)
A. The user device profile is not associated to the correct end user.
B. The username must be numeric only and must match the DN.
C. The Extension Mobility service has not been enabled under the Cisco Unified Serviceability Page.
D. Extension Mobility has not been enabled under Enterprise Parameters.
E. The user must ensure that their main endpoint is online and registered, otherwise they cannot log in elsewhere.
Answer: A,C
Q108. 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
Q109. During device failover to the secondary Cisco Unified Communications Manager server, how does the phone recognize that the primary server is back?
A. The secondary server keeps sending keepalive message to the primary server and when it succeeds, it unregisters the phones to force them to register to the primary.
B. When the primary server goes online, it sends out an "ALIVE" message via broadcast so that the phones re-register.
C. The phones never re-register with the primary server until the active (secondary) one goes down.
D. The phone sends keepalive messages to the primary server frequently and when it succeeds, the phone re-registers with it.
Answer: D
