Oracle Database Administration II — Question 78

Which two are true about RMAN duplexed backup sets? (Choose two.)

Answer options

• A. They can be written only to disk.
• B. They must be written to media.
• C. They can be created by using the RMAN CONFIGURE command to specify duplexing before taking a backup.
• D. They can be created only by using the COPIES option of a BACKUP command.
• E. They can be written to media.

Correct answer: C, E

Explanation

The correct answer C indicates that duplexed backup sets can be configured using the RMAN CONFIGURE command before performing a backup. Answer E is also correct, as these backup sets can indeed be stored on media. Options A and B are incorrect as they restrict the storage options to disk and media respectively, while D incorrectly states that duplexing can only be done through the COPIES option.
