問題文
A cluster runs 1:1 redundancy with all devices distributed 100 percent to the primary call processing subscriber. On that primary node the CTI Manager service stops but the call processing service keeps running. What happens to the phones and to the devices that the CTI application controls?
選択肢
- The phones stay registered where they are, and the CTI Manager on the backup node takes over and goes on watching and driving those devices even though they are registered to a call processing service that runs on the other node.
- The phones are registered onto the backup node, and the CTI devices stay under the control of the primary node, given that the application keeps its open session.
- The phones move to the backup node and are registered there together with the CTI devices, because the two services always fail over as a single unit.
- The phones stay registered where they are, and the CTI devices fall out of the application's control until the service on the primary node has been restarted.
