QUESTION 141
Which statement about the effective path in the Enhanced Location Call Admission Control mechanism on Cisco Unified Communications Manager is true?
A. It is a sequence of links and intermediate locations that connect a pair of locations.
B. It is used to define the bandwidth that is available between locations.
C. Only one effective path is used between two locations.
D. There could be multiple effective paths between a pair of locations.
E. It logically represents the WAN link.
Answer: C
Explanation:
The effective path is the path used by Unified CM for the bandwidth calculations, and it has the least cumulative weight of all possible paths. Weights are used on links to provide a “cost” for the “effective path” and are pertinent only when there is more than one path between any two locations.
QUESTION 142
Which configuration component in Cisco Unified Communications Manager Enhanced Location Call Admission Control is designated to participate directly in intercluster replication of location, links, and bandwidth allocation data?
A. an active member of a Location Bandwidth Manager Group
B. a member of a Location Bandwidth Manager Hub Group
C. a standby member of a Location Bandwidth Manager Group
D. all members of a Location Bandwidth Manager Group
E. a shadow member of a Location Bandwidth Manager Hub Group
Answer: B
Explanation:
A Location Bandwidth Manager (LBM) service that has been designated to participate directly in intercluster replication of fixed locations, links data, and dynamic bandwidth allocation data. LBMs assigned to an LBM hub group discover each other through their common connections and form a fully-meshed intercluster replication network. Other LBM services in a cluster with an LBM hub participate indirectly in intercluster replication through the LBM hubs in their cluster.
QUESTION 143
What is the amount of audio bandwidth, in kilobits per second, that is used in the Cisco Unified Communications Manager location bandwidth calculation for a G.728 call?
A. 8
B. 16
C. 24
D. 29
E. 80
Answer: B
Explanation:
G.728–Low-bit-rate codec that video endpoints support.It support kilobits per second
QUESTION 144
When neither the active or standby Location Bandwidth Manager in the configured LBM group is available, what will the Cisco CallManager service on a subscriber Cisco Unified Communications Manager server do to make location CAC decisions?
A. It will attempt to communicate with the first configured member in the Location Bandwidth Manager hub group.
B. It will use the Call Treatment When No LBM Available service parameter with the default action to allow calls.
C. It will use the Call Treatment When No LBM Available service parameter with the default action to reject calls.
D. It will attempt to communicate with the local LBM service for location CAC decisions.
E. It will allow all calls until communication is reestablished with any configured servers in the LBM group.
Answer: D
Explanation:
By default the Cisco CallManager service communicates with the local LBM service; however, LBM groups can be used to manage this communication. LBM groups provide an active and standby LBM in order to create redundancy for Unified CM call control.
QUESTION 145
Which system location is used for intercluster Enhanced Location CAC on Cisco Unified Communications Manager?
A. Hub_None
B. Default
C. Intercluster
D. Phantom
E. Shadow
Answer: E
Explanation:
The shadow location is used to enable a SIP 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. In order to pass this location information across clusters, the SIP intercluster trunk (ICT) 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 SIP ICT 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 SIP ICT 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.
QUESTION 146
Refer to the exhibit. All displayed devices are registered to the same Cisco Unified Communications Manager server and the phones are engaged in an active call.

E. The IP Phone A user hears no on-hold music.
Answer: C
Explanation:

QUESTION 148
Router A and router B are Cisco IOS 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
QUESTION 149
Which Device Pool configuration setting will override the device-level settings only when a device is roaming within a device mobility group?
A. Region
B. Location
C. SRST Reference
D. Calling Party Transformation CSS
E. Media Resource Group List
Answer: D
