Q2. Refer to the exhibit.
What must be configured on the HQ Cisco Unified Communications Manager to allow HQ users to dial the SAF learned directory number pattern 3XXX?
A. Route pattern 3XXX should be configured and made available to HQ users through the phone CSS.
B. Route pattern 3XXX should be configured and made available to HQ phone users through the phone AAR CSS.
C. The SAF partition assigned to the SAF learned patterns must be available to the HQ phone users through the phone CSS.
D. The SAF partition assigned to the SAF learned patterns must be available to the HQ phone users through the phone AAR CSS.
E. The SAF directory number pattern 3XXX will be made available to all users automatically as soon as the SAF partition is selected.
Answer: C
Explanation:
Incorrect Answer: A, B, D By adopting the SAF network service, the call control discovery feature allows Cisco Unified Communications Manager to advertise itself along with other key attributes.

Q3. Refer to the exhibit.
The HQ Cisco Unified Communications Manager has been configured for end-to-end
RSVP. The BR Cisco Unified Communications Manager has been configured for local
RSVP.
RSVP between the locations assigned to the IP phones and SIP trunks at each site are configured with mandatory RSVP. When a call is placed from the IP phone at HQ to the BR phone at the BR site, which statement is true?
A. The Cisco Unified Communications Manager at HQ will fall back to local RSVP and place the call. No RSVP end-to-end will occur.
B. RSVP end-to-end will occur.
C. The Cisco Unified Communications Manager at HQ will use end-to-end RSVP. The BR Cisco Unified Communications Manager will use local RSVP.
D. The call will fail.
E. The call will proceed as a normal call with no RSVP reservation.
Answer: D
Explanation:
Incorrect Answer: A, B, C A possible cause is that the same router is being used as the calling and called RSVP agents, and that router is not running the latest IOS version, which supports loopback on RSVP reservation. Make sure that the router is running the latest IOS version. Link: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/8_6_1/ccmsys/a02rsvp.html #wp1155102
Q4. Which system configuration is used to set audio codecs?
A. region
B. location
C. physical location
D. licensing
Answer: A
Q5. If your IP telephony administrator asks you to configure a local zone for your dial plan to control the volume of calls between two end points in a centralized multisite environment, which two types of Call Admission Control can be implemented? (Choose two.)
A. locations based
B. automated alternate routing
C. gatekeeper based
D. SRST
E. Cisco Unified Communications Manager based
Answer: A,B
Explanation:
Incorrect Answer: C, D, E Location-based call admission control (CAC) manages WAN link bandwidth in Cisco Unified Communications Manager. Automated alternate routing (AAR) provides a mechanism to reroute calls through the PSTN or other network by using an alternate number. Link: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/8_6_1/ccmsys/a02cac.html #wp1067747
Q6. Which component of Cisco Unified Communications Manager is responsible for sending keepalive messages to the Service Advertisement Framework forwarder?
A. Call Control Discovery requesting service
B. Hosted DNs service
C. Service Advertisement Framework client control
D. Cisco Unified Communications Manager database
E. Service Advertisement Framework-enabled trunk
F. gatekeeper
Answer: C
Q7. In a distributed call processing network with locations-based CAC, calls are routed to and from intercluster trunks. Which trunk type is implemented in this network?
A. intercluster trunk with gatekeeper control
B. intercluster trunk without gatekeeper control
C. SIP trunk
D. h225 trunk
Answer: B
Q8. Which two statements describe RSVP-enabled locations-based CAC? (Choose two.)
A. RSVP can be enabled selectively between pairs of locations.
B. Using RSVP for CAC simply allows admitting or denying calls based on a logical
configuration that is ignoring the physical topology.
C. RSVP is topology aware, but only works with full mesh networks.
D. An RSVP agent is a Media Termination Point that the call has to flow through.
E. RSVP and RTP are used between the two endpoints.
Answer: A,D
Explanation:
Incorrect Answer: B, C The RSVP policy that is configured for a location pair overrides the default interlocation RSVP policy that configure in the Service Parameter Configuration window. RSVP supports audio, video, and data pass-through. Video data pass-through allows video and data packets to flow through RSVP agent and media termination point devices Link: https://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/8_6_1/ccmsys/a02rsvp.ht ml#wp1070214
Q9. Refer to the exhibit.
HQ_MRGL is assigned to the HQ IP phones. BR_MRGL is assigned to the BR IP phones. The remote site BR IP phones support only the G.711 codec. Where should the transcoder reside?
A. The transcoder should reside at the HQ site and assigned to HQ_MRG.
B. The transcoder should reside at the BR site and assigned to BR_MRG.
C. The transcoder should be assigned to its own MRG, which should then be assigned to the default device pool.
D. A transcoder is not needed. The HQ phones will automatically change over to the G.711 codec.
Answer: B
Q10. A Cisco Unified Communications Manager cluster is installed in headquarters only.
How can international calls be blocked while national calls are allowed for branch office Cisco IP Phones during a WAN failure?
A. Configure CSS and partitions in Cisco Unified Communications Manager and apply the CSS and partitions to the SRST ISR.
B. Configure CSS and partitions in the SRST ISR.
C. Configure COR in the SRST ISR.
D. Configure voice translations in the SRST ISR.
Answer: C
Q11. 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:
