What are possible methods of migration to the Autonomous Data Warehouse?

The correct answer is C, indicating that both GoldenGate and Data Pump are valid methods for migrating data to the Autonomous Data Warehouse.

GoldenGate is a real-time data integration and replication solution that allows for continuous data capture, enabling organizations to synchronize and replicate data across multiple systems efficiently. This is particularly useful for migrating large volumes of data without significant downtime since it can facilitate real-time updates during the migration process, ensuring data consistency and reducing the risk of data loss.

Data Pump, on the other hand, is a utility for quickly exporting and importing data and metadata between Oracle databases. It is well-suited for bulk data migration tasks, providing high performance and flexibility in the management of data movements. Using Data Pump can help in efficiently migrating large datasets at once, which is often a requirement for moving to a data warehouse environment.

Employing both methods offers a comprehensive approach to data migration, where GoldenGate can handle real-time changes and Data Pump can be utilized for batch data movements, catering to different migration scenarios and requirements.

The other choices fail to capture the complete range of migration methods available, underscoring the importance of recognizing both tools as integral to the process.
