An HADR environment has two standby databases one principal and one auxiliary. What is the only mode that can be used to transfer data to the auxiliary standby?
In an HADR (High Availability Disaster Recovery) environment with two standby databases, one principal and one auxiliary, the only mode that can be used to transfer data to the auxiliary standby is SUPERASYNC. This mode ensures that data transfer has the least impact on the performance of the primary database by not waiting for acknowledgment from the standby, making it suitable for the auxiliary standby.
The answer "D. SUPERASYNC" is correct, all of the HADR synchronization modes are supported on the principal standby, but the auxiliary standbys can only be in SUPERASYNC mode.
