You work as a Database Administrator for your company. The company uses Oracle as its database. The manager of the company wants you to move the company's databases to another server, as the performance of the old server is now degraded. Which of the following RMAN commands will you use to accomplish the task?

Answer: A

Explanation: Answer option A is correct. The RMAN's DUPLICATE command uses backups of the target database to create a duplicate database that can be used for testing purposes or to create a standby database. The command is also used to move the database to a new server. In order to move a database from one location to another, user-managed incomplete recovery options such as utilizing the backup control file in conjunction with the RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL command can be used. B is incorrect. The CONVERT command is used to convert data file formats to transport tablespaces across various platforms. C is incorrect. The CONNECT command is used to establish a connection between RMAN and a target, auxiliary, or recovery catalog database. D is incorrect. The REGISTER command is used to register the target database in the recovery catalog.
