  • 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: Option 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.
