In a Mission Critical AACC High Availability (HA) campus solution, there are two types of switchovers, managed and unmanaged. A managed switchover is one initiated by the administrator or caused by a failure of a monitored Contact Center Manager Server (CCMS) or Communication Control Toolkit (CCT) component. An unmanaged switchover results from a hardware, network, database or power failure.
Which three conditions must be satisfied before a switch over can occur? (Choose three.)
- A: The active server database and standby server database are synchronized, and the standby server database is shadowing the active server database.
- B: On the active server, all critical CCMS and CCT services are monitored and running.
- C: The active and standby servers are in a running state.
- D: The active and standby servers have switchover enabled.
