Oracle Database 12c: Advanced Administration — Question 18

You execute the RMAN commands:
RMAN> CONFIGURE DEFAULT DEVICE TYPE TO disk;
RMAN> CONFIGURE DEVICE TYPE disk PARALLELISM 2;
RMAN> CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT /disk1/%U;
RMAN> CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT /disk2/%U;
RMAN>BACKUP DATABASE;
Which statement is true about the backup set created by the BACKUP command?

Answer options

• A. The default channel is allocated and the backup set is created in only one destination.
• B. Two channels are allocated and backup pieces for the backup set are created in both the specified destinations.
• C. Two channels are allocated and two copies of the backup set are taken in parallel in both locations.
• D. Two channels are allocated and a copy of the backup set is taken in the location specified by CHANNEL 2.

Correct answer: D

Explanation

The correct answer is D because the configuration specifies two channels, but only the channel defined by CHANNEL 2 is used for the backup set. Options A, B, and C are incorrect as they imply that the backup would be in multiple locations or would not use the defined channels correctly.
