What is a key feature of database-level protection in SQL Server after failover?

The correct choice highlights that transactions captured in the transaction log are accounted for during the failover process. In SQL Server, the transaction log plays a crucial role in data integrity and recovery. When a failover occurs—such as in a high-availability scenario where the primary database instance becomes unavailable—the transaction log ensures that any committed transactions are preserved and can be replayed on the secondary server. This allows the database to maintain its consistency and ensures that all changes made to the data are accounted for, thereby protecting against data loss.

Transaction logs keep track of all modifications made to the database, allowing the SQL Server to restore the database to its last consistent state after failover. This feature is foundational for achieving high availability and data protection in SQL Server environments, ensuring that users only experience minimal downtime and data integrity remains intact.

In contrast, the other options do not accurately reflect the capabilities or behaviors concerning failover in SQL Server. For example, the automatic transfer of SQL Server Agent jobs is not guaranteed and typically requires additional configuration. The recovery process does not simply involve the restoration of database files without considering the transaction log. Additionally, linked servers require separate configuration and do not automatically transfer during failover, as they are not integral to the failover process itself.
