Choose the best answer You want to create a duplicate database DUP_DB from your production database PROD on the same host. The PROD database uses Automatic Storage Management (ASM) for storage. Regular backups are taken using RMAN connected to a recovery catalog. You create an auxiliary instance and want to execute the command: RMAN> DUPLICATE TARGET DATABASE TO dup_db FROM ACTIVE DATABASE; What is a prerequisite for the successful execution of this command

• A.RMAN must be connected to the target database instance and the auxiliary instance.
• B.A most recent backup set of the PROD database must exist.
• C.The target database must be in MOUNT state.
• D.Flashback must be enabled for the PROD database.

• B.Automatic conversion of endianness occurs.
• C.The source PDB must not be an application root.
• D.The source PDB can be in MOUNT or OPEN state.
