Demo Questions

Question 1

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

Correct Answer: B

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 2

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

Correct Answer: B

G.728—Low-bit-rate codec that video endpoints support.It support kilobits per second




Question 3

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.

Correct Answer: D

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 4

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

Correct Answer: E

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 5

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. Assuming the provided configurations exist at the phone line level and multicast MOH is disabled clusterwide, what will happen when the user of IP Phone B presses the Hold softkey?

  • A: IP Phone A receives audio source 2 from MOH Server A.
  • B: IP Phone A receives audio source 3 from MOH Server A.
  • C: IP Phone A receives audio source 2 from MOH Server B.
  • D: IP Phone A receives audio source 3 from MOH Server B.
  • E: IP Phone A receives audio source 1 from MOH Server A.

Correct Answer: B

Held parties determine the media resource group list that a Cisco Unified Communications Manager uses to allocate a music on hold resource.




Question 6

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. Assuming the provided configurations exist at the phone line level and multicast MOH is disabled clusterwide, what will happen when the user of IP Phone A presses the Transfer softkey?

  • A: The IP Phone B user hears audio source 3 from MOH Server A.
  • B: The IP Phone B user hears audio source 4 from MOH Server B.
  • C: The IP Phone B user hears audio source 3 from MOH Server B.
  • D: The IP Phone B user hears audio source 2 from MOH Server B.
  • E: The IP Phone A user hears no on-hold music.

Correct Answer: C

Held parties determine the media resource group list that a Cisco Unified Communications Manager uses to allocate a music on hold resource.




Question 7

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.

Correct Answer: A




Question 8

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

Correct Answer: D

Device Mobility Related Settings:
The parameters under these settings will override the device-level settings only when the device is roaming within a Device Mobility Group. The parameters included in these settings are:
Device Mobility Calling Search Space 
AAR Calling Search Space 
AAR Group 
Calling Party Transformation CSS 
Called Party Transformation CSS 
The device mobility related settings affect the dial plan because the calling search space dictates the patterns that can be dialed or the devices that can be reached.




Question 9

Which two Device Pool configuration settings will override the device-level settings when a device is roaming within or outside a device mobility group? (Choose two.)

  • A: Adjunct CSS
  • B: Device Mobility CSS
  • C: Network Locale
  • D: Called Party Transformation CSS
  • E: AAR CSS
  • F: Device Mobility Group

Correct Answer: CF

The parameters under these settings will override the device-level settings when the device is roaming within or outside a Device Mobility Group. The parameters included in these settings are:
Date/time Group 
Region 
Media Resource Group List 
Location 
Network Locale 
SRST Reference 
Physical Location 
Device Mobility Group 
The roaming sensitive settings primarily help in achieving proper call admission control and voice codec selection because the location and region configurations are used based on the device's roaming device pool.

Question 10

Which Call Admission Control mechanism is supported for the Cisco Extension Mobility Cross Cluster solution?

  • A: Location CAC
  • B: RSVP CAC
  • C: H.323 gatekeeper
  • D: intercluster Enhanced Location CAC
  • E: visiting cluster's LBM hub

Correct Answer: B

Configuring extension mobility cross cluster (EMCC) is nothing you should take lightly. EMCC requires a lot of configuration parameters including the exporting and importing of each neighbor cluster’s X.509v3 digital certificates. EMCC is supported over SIP trunks only. Presence is another feature that’s only supported over SIP trunks. If you want to be able to perform scalable Call Admission Control (CAC) in a distributed multi-cluster call processing model, you will need to point an H.225 or Gatekeeper controlled trunk to an H.323 Gatekeeper for CAC… but if you want to support presence and EMCC between clusters and maintain CAC.
