Oracle Cloud Infrastructure 2022 Architect Professional — Question 21

Your company needs to migrate a business critical application from your data center to Oracle Cloud Infrastructure (OCI). The application runs on Oracle Database and both the application and database servers run on Oracle Linux version 7. The application server is WebLogic server running on multiple 4-core servers and the database is deployed as an Oracle Database Enterprise Edition RAC database on 2 servers (4-cores each).
Which method of database migration should you choose so that the application has minimal impact?

Answer options

• A. Deploy Exadata Cloud Service Base rack and use Oracle Data Pump tool to migrate the data from customer on-premises to OCI.
• B. Deploy Autonomous Transaction Processing Database on OCI and use the MV2ADB tool for the database migration.
• C. Deploy Virtual Machine RAC DB system on OCI and use the Oracle Database Backup module with RMAN to migrate the data from customer on-premises to OCI.
• D. Deploy Virtual Machine RAC DB system on OCI and use the ZDM tool for the database migration.

Correct answer: D

Explanation

The correct answer is D because the ZDM tool is specifically designed for zero downtime migrations, allowing the application to remain operational during the transition. Other options, while viable, may involve more downtime or complexity that could negatively affect the application's availability and performance during the migration process.
