Oracle Data Guard Overview

Which TWO statements are true about offloading backups to a physical standby database in a Data Guard environment?

Choose two
  • A The standby database must be registered in an RMAN catalog before the primary database has been registered.
  • B The standby database must be registered in an RMAN catalog after the primary databases has been registered.
  • C The standby database can not registered in an RMAN catalog if the primary database has not been registered.
  • D Backups of the standby control file taken while connected to the catalog where the database is registered, may be used to restore the control file on the primary database.
Explanation

A physical standby shares the primary database’s DBID and is registered in the recovery catalog in relation to its registered primary database; RMAN does not require a separate, manually ordered standby registration. RMAN catalog metadata also makes backups of standby and nonstandby control files interchangeable, allowing a standby control-file backup to restore the primary control file.
