Which three are true regarding prerequisites for a logical standby database as a disaster recovery solution? (Choose three.)
To ensure a logical standby database functions correctly as a disaster recovery solution, it is important to ensure that no ROWID data types are contained in the primary database, as these are not supported by logical standby databases. Additionally, supplemental logging must be enabled on the primary database to guarantee that the necessary changes are logged and can be applied to the standby database. Lastly, BFILE LOB data types should not be used in the primary database because they are also not supported by logical standby databases.
