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.

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.
