• B. The UNDO TABLESPACE clause is always required when no connection exists to the TARGET instance.
• C. RMAN ג€pushesג€ the backups of the database to be duplicated over the network to the auxiliary instance.
• D. The NOREDO clause can be used if the backups of the database being duplicated were taken when the database was in ARCHIVELOG mode.
• E. RMAN SBT-based backups of the database to be duplicated can be used by the auxiliary instance.
• F. The UNDO TABLESPACE clause is always required when no connection exists to the recovery catalog and the TARGET database is closed.
• G. The UNDO TABLESPACE clause is always required when no connection exists to the recovery catalog and the TARGET database is opened.
• H. RMAN disk-based backups of the database to be duplicated can be used by the auxiliary instance.

Correct answer: A, E, F, H

Explanation

The correct answers A, E, F, and H reflect the requirements and capabilities of RMAN duplication without a TARGET connection. Options B, C, D, and G introduce inaccuracies regarding the necessity of the UNDO TABLESPACE clause and the process of backup transfer. Option D is incorrect because the NOREDO clause is not applicable when using backups from an ARCHIVELOG mode database.
