28題、Your production database is running in archivelog mode. You use RMAN with a recovery catalog to back up your database to media and the database is uniquely identified in the recovery catalog. You want to create a test database from the production database and allow the production database to remain open during the duplicate process. You restore the database backups to a new host with the same directory structure as the production database and want to use the recovery catalog for future backups after the database is successfully restored to the new host.
How would you achieve this?
A. by using the RMAN switch command to set the new location for the data files
B. by using the RMAN duplicate command with nofilenamecheck to recover the database to the new host
C. by using the RMAN duplicate command with dbid and set new name for tablespace to recover the database to the new host
D. by creating a new database in the new host, and then using the RMAN recover command
Answer: B
( 因為是恢復的相同的路徑下，所以 duplicate 的時候要用到 nofilenamecheck 選項，命令如下：
duplicate target database from active database do recover nofilenamecheck;)
