When migrating an Oracle database, you must be aware of source and target requirements. Which two statements are true about using Oracle Zero Downtime Migration (ZDM)? (Choose two.)
A.
Source Oracle Single Instance Databases can be migrated to Oracle RAC Databases with Oracle ZDM.
B.
When migrating with Oracle ZDM, if the target database is at a higher patch level than the source database, the datapatch utility runs on the target database as a postmigration task.
C.
Source Oracle Real Application Clusters (RAC) Databases can be migrated to Single Instance Databases with Oracle ZDM.
D.
ZDM allows migration from source databases of a higher version to target databases of a lower version.
The correct statements about using Oracle Zero Downtime Migration (ZDM) are:
A. Source Oracle Single Instance Databases can be migrated to Oracle RAC Databases with Oracle ZDM.
Oracle ZDM supports migration from single-instance databases to Oracle Real Application Clusters (RAC) databases, allowing for scalability and high availability on the target environment.
B. When migrating with Oracle ZDM, if the target database is at a higher patch level than the source database, the datapatch utility runs on the target database as a postmigration task.
This is true because Oracle ZDM handles patch level differences, and if the target has a higher patch level, ZDM will automatically run the datapatch utility on the target database as part of the post-migration tasks to ensure consistency.
