Oracle Cloud Infrastructure 2020 Architect Professional — Question 42

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? (Choose the best answer.)

Answer options

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

Correct answer: A

Explanation

The correct answer is A because using the Oracle Database Backup module with RMAN allows for a backup and restore method that minimizes downtime, which is crucial for business-critical applications. Option B, while using ZDM, may not be as effective in this specific scenario as RMAN for minimizing impact. Option C involves migrating to a different database type, which could introduce complexities. Option D, although viable, typically involves more overhead and isn't as efficient for this particular migration need.
