Which three are true?

    Correct Answer: B, C, E

    The Fast-Start Failover configuration provides several details that help determine the correct answers. An automatic failover is possible even if the target standby database lags behind the primary, since the lag limit is not in use. The configuration shows that the observer is active (017.example.com), indicating that it is running. Additionally, since the Fast-Start Failover Lag Limit is not used in Maximum Availability mode but applicable in Maximum Performance mode, it suggests that the configuration might be operating in Maximum Availability mode because the lag limit is not in use. A direct indication that the system operates in Maximum Availability or Maximum Performance mode is not explicitly provided, so it requires inference based on the limitations and properties set.
