Examine the RMAN command:
Which statement is true about the command?
A. It creates compressed backup sets.
B. It uses asynchronous I/O for the backup.
C. It uses parallelization for the backup set.
D. It uses multisection backup.
Correct Answer: C
Explanation/Reference:
SBT stands for Serial Backup Tape.
Configuring Parallel Channels for Disk and SBT Devices
The number of channels available for a device type when you run a command determines whether RMAN reads or writes in parallel. As a rule, the number of channels used in executing a command should match the number of devices accessed.
For tape backups, allocate one channel for each tape drive.
