Troubleshooting

Which three statements describe failures in the high availability of the Cisco Unified Intelligent Contact Management central controller?

Choose three
  • A If ICM Logger side A fails, router side B cannot send historical info to ICM Logger side A and is limited to ICM Logger side B.
  • B If the private LAN fails, the Peripheral Gateways are used to help determine the active call router side of the duplex pair.
  • C If ICM Logger side A fails, the impact of call processing is limited to ICM call router side A.
  • D If one ICM call router of a duplex pair of Cisco Unified ICM call routers fails, the surviving ICM call router recognizes the failure when it receives no response to heartbeats over the private LAN.
  • E There is no impact on call processing during a Cisco Unified ICM Logger failure.
  • F During Cisco Unified ICM call router failover processing, calls in progress in Cisco Unified Customer Voice Portal are disconnected, but all new calls are processed successfully.
Explanation

On a private-network failure, enabled Peripheral Gateways contact the other Router over the public network to determine its state before the Router assumes isolated-enabled or isolated-disabled operation. Redundant components detect failures through private-network heartbeats. A Logger failure has no immediate impact on call processing because the redundant Logger receives the complete call data from its local Router.
