Final answer:
The answer to the question is the active secondary clustering method, in which a secondary server continuously syncs with the primary server to ensure high availability and updated data in case of primary server failure.
Step-by-step explanation:
With the active secondary clustering method, data are continuously copied from primary to secondary server. When a clustering environment uses an active secondary model, it means that the secondary server, also known as a replica or mirror, is constantly syncing with the primary server. This configuration allows for high availability, as the secondary server can take over immediately should the primary server fail. The data are mirrored in real-time or near-real-time to ensure that the secondary server's data is as up-to-date as possible. In the active secondary clustering method, data is continuously copied from the primary to the secondary server. This ensures that the secondary server is always up-to-date with the primary server.
Example: In a database system, the active secondary clustering method allows for high availability and fault tolerance. If the primary server fails, the secondary server can instantly take over and continue serving requests without any data loss.
