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.)
A.
The database must be running an Archive Log mode.
B.
The database must have Transparent Data Encryption (TDE) enabled.
C.
The database must be stored in an Automatic Storage Management Cluster File System (ACFS).
D.
The source database server must allow incoming connections from the ZDM service host on to Port 22.
E.
The database must have a configured TDE wallet if the version is Oracle Database 11g Release 2 or 12c Release 1.
The two prerequisites that must be addressed before the source database can be migrated using Oracle Zero Downtime Migration (ZDM) are:
A. The database must be running in Archive Log mode.
Archive Log mode is required to ensure that all transactions are captured and that the database can be recovered to a specific point in time during migration.
D. The source database server must allow incoming connections from the ZDM service host on Port 22.
Port 22 is typically used for SSH, which is necessary for ZDM to connect to the source database server and perform the migration tasks.
These two prerequisites ensure that the database can be migrated with minimal downtime and that ZDM can communicate with the source database server to carry out the migration process.
