Question 11

For a source database to be successfully migrated, you must view and apply the prerequisites.

Which two prerequisites must be addressed before the source database can be migrated using Oracle Zero Downtime Migration (ZDM)? (Choose two.)

The database must be running an Archive Log mode.

The database must have Transparent Data Encryption (TDE) enabled.

The database must be stored in an Automatic Storage Management Cluster File System (ACFS).

The source database server must allow incoming connections from the ZDM service host on to Port 22.

The database must have a configured TDE wallet if the version is Oracle Database 11g Release 2 or 12c Release 1.

Correct Answer: A, D

For a source database to be successfully migrated using Oracle Zero Downtime Migration (ZDM), certain prerequisites must be met. First, the database must be running in Archive Log mode. This is necessary because ZDM requires the ability to access archive logs to ensure data consistency and facilitate fast recovery. Second, the source database server must allow incoming connections from the ZDM service host on Port 22. Port 22 is typically used for SSH connections, and this access is needed for ZDM to communicate securely with the source database server during the migration process.
