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? 

Answer options:

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.

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.
