New Questions 13
Which two applications must be connected to a leaf cluster in a Cisco Unified Communications Manager Session Management Edition deployment? (Choose two.)
A. Cisco Unified Meeting Place
B. Cisco Unified Contact Center Express
C. H.323-based video conferencing systems
D. Cisco Unity
E. Cisco Unified Communications Manager
F. fax servers
Answer: B, E
Explanation:
The deployment of a Unified CM Session Management Edition enables commonly used applications, such as conferencing or videoconferencing to connect directly to the session management cluster, which reduces the overhead of managing multiple trunks to leaf systems.
Unified CM Session Management Edition supports the following applications:
u2022 Unity, Unity Connection
u2022 Meeting Place, Meeting Place Express
u2022 SlP and H.323-based video conferencing systems
u2022 Third Party voice mail systems
u2022 Fax servers
u2022 Cisco Unified Mobility
The following applications must connect to the leaf cluster:
u2022 Unified Contact Centre, CUCM, Unified Contact Centre Express
u2022 Cisco Unified Presence Server
u2022 Attendant Console
u2022 Manager Assistant
u2022 lP lVR
u2022 Cisco Voice Portal

New Questions 15
Which Cisco Unified Communications Manager partition will be associated with a directory URl that is configured for an end user with a primary extension?
A. null
B. none
C. directory URl
D. default
E. any partition that the Cisco Unified Communications Manager administrator desires
Answer: C
Explanation:
Cisco Unified Communications Manager supports dialing using directory URls for call addressing. Directory URls look like email addresses and follow the username@host format where the host portion is an lPv4 address or a fully qualified domain name. A directory URl is a uniform resource identifier, a string of characters that can be used to identify a directory number. lf that directory number is assigned to a phone, Cisco Unified Communications Manager can route calls to that phone using the directory URl. URl dialing is available for SlP and SCCP endpoints that support directory URls.
New Questions 16
Refer to the exhibit.
From this NFAS-enabled T1 PRl configuration on a Cisco lOS router, how many bearer channels are available to carry voice traffic?
A. 91
B. 92
C. 93
D. 94
E. 95
Answer: E
Explanation:
A T1 circuit typically carries 24 individual timeslots. Each timeslot in turn carries a single telephone call. When a T1
circuit is used to carry Primary Rate lSDN one of the timeslots is used to carry the D channel. A single Primary Rate lSDN circuit is thus sometimes described as 23B + D. There are 23 bearer channels carrying voice or data, and one D channel carrying the Common Channel Signaling. ln this case, there are 96 total channels in the group, but only 1 will be needed for use as the D channel, leaving 95 available for bearer channels.
New Questions 17
Which statement describes the supported integration method when Cisco Unity Connection and Cisco Unified Communications Manager are installed on the same server as Cisco Unified Communications Manager Business Edition?
A. Only SCCP integration is supported.
B. Only SlP integration is supported.
C. Both SCCP or SlP integration are supported, but you must choose one or the other.
D. Q-Sig integration is supported through a voice-enabled Cisco lSR router.
E. Circuit-switched integration is supported through PlMG.
Answer: A
Explanation:
When installed on the same server there is no way to create trunk that is why sccp is the only way Cisco Unity Connection and Cisco Unified Communications Manager are installed on the same server.
New Questions 18
How many signaling bits are there in each T1 time slot using channel associated signaling with Super Frame?
A. 1
B. 2
C. 4
D. 8
E. 12
Answer: B
Explanation:
Each T1 CAS has 24 channels that can transmit 8 bits per channel each. This gives us a total of 192 bits. The T1 has one additional bit for framing, bringing the total to 193 bits. Two types of line coding can be used on a T1 CAS. The first type of line coding is called Super Frame (SF). This is an older and less - efficient type of framing. Super Frame bundles 12 of these 193 - bit frames together for transport. lt then uses the even -numbered frames as signaling bits. The T1 CAS signaling then looks at every sixth frame for signaling information. This comes out to be 2 bits that are referred to as the A and B bits, which reside in frames 6 and 12.

Which system location is used for intercluster Enhanced Location CAC on Cisco Unified Communications Manager?
A. Hub_None
B. Default
C. lntercluster
D. Phantom
E. Shadow
Answer: E
Explanation:
The shadow location is used to enable a SlP trunk to pass Enhanced Location CAC information such as location name and Video-Traffic-Class (discussed below), among other things, required for Enhanced Location CAC to function between clusters. ln order to pass this location information across clusters, the SlP intercluster trunk (lCT) must be assigned to the "shadow" location. The shadow location cannot have a link to other locations, and therefore no bandwidth can be reserved between the shadow location and other locations. Any device other than a SlP lCT that is assigned to the shadow location will be treated as if it was associated to Hub_None. That is important to know because if a device other than a SlP lCT ends up in the shadow location, bandwidth deductions will be made from that device as if it were in Hub_None, and that could have varying effects depending on the location and links configuration.

New Questions 21
Router A and router B are Cisco lOS routers with hardware CFB resources that are registered to the same Cisco Unified Communications Manager server. Which Media Resource Group and Media Resource Group List configuration should be implemented if an administrator wants to make sure that all provisioned DSPs on router A are consumed before router B's DSP is used?
A. Router A's CFB and router B's CFB should each be configured in its own MRG. Both MRGs should then be grouped into the same MRGL, but the MRG that contains router A's CFB should be listed in higher order than the MRG that contains router B's CFB. Finally, associate the MRGL to all conference resource consumers.
B. Router A's CFB and router B's CFB should each be configured in its own MRG. Both MRGs should then be further separated into different MRGLs. Finally, associate the MRGL that contains router A's CFB in higher order than router B's CFB to all conference resource consumers.
C. Router A's CFB and router B's CFB should both be configured in the same MRG with router A's CFB listed higher than that of router B. Then associate the MRG with an MRGL and apply it to all conference resource consumers.
D. Router A's CFB and router B's CFB should both be configured in the same MRG. Make sure router A's CFB is listed in a higher alphabetical order than router B's CFB. Then associate the MRG with an MRGL and apply it to all conference resource consumers.
E. Router A's CFB and router B's CFB should both be configured in the same MRG. Use Cisco Unified Communications Manager service parameters to assign a higher priority to router A's CFB. Then associate the MRG with an MRGL and apply it to all conference resource consumers.
Answer: A
New Questions 22
Which statement about application inspection of SAF network services on an adaptive security appliance is true?
A. The adaptive security appliance can inspect and learn the ephemeral port numbers that are used by H.225 and H.245 on SAF-enabled H.323 trunks.
B. An explicit ACL must be configured on the adaptive security appliance for SAF-enabled SlP trunks.
C. An explicit ACL must be configured on the adaptive security appliance for SAF-enabled H.323 trunks to account for ephemeral port numbers that are used by H.225 and H.245.
D. The adaptive security appliance can inspect and learn the ephemeral port numbers that are used by H.225 on SAF-enabled H.323 trunks, but H.245 ports must be explicitly defined.
E. The adaptive security appliance provides full application inspection for SAF network services.
Answer: C
Explanation:
The Adaptive Security Appliances do not have application inspection for the SAF network service. When Unified CM uses a SAF-enabled H.323 trunk to place a call, the ASA cannot inspect the SAF packet to learn the ephemeral port number used in the H.225 signaling. Therefore, in scenarios where call traffic from SAF-enabled H.323 trunks traverses the ASAs, ACLs must be configured on the ASAs to allow this signaling traffic. The ACL configuration must account for all the ports used by the H.225 and H.245 signaling.
