You want to take the backup of the USERS tablespace. It has a single data file of 900 MB. You have tape drives of 300 MB each. The SBT channel is configured for Recovery Manager (RMAN).To accomplish the backup, you issued the following RMAN command:RMAN> BACKUP SECTION SIZE 300M TABLESPACE users;Which two statements are true about the execution of the above command? （）(Choose two.)
A. The backup piece size will be limited to 300 MB
B. The RMAN uses multiplexing to perform backup
C. The operation is accomplished using the default channel available
D. The RMAN parallelizes the backup although the parallelism is not set for a channel
第2题：
What feature comes into play to help ensure the completion of the backup should one of three backup devices fail during a backup that is using three different channels?（）
第3题：
Tape streaming is not happening while performing RMAN tape backup. On investigation, you find that it is not because of the incremental backup or the empty file backup and that RMAN is sending data blocks to the tape drive fast enough.What could be a solution to make tape streaming happen during the backup?（）
A. Configure backup optimization
B. Configure the channel to increase MAXOPENFILES
C. Configure the channel to increase the capacity with the RATE parameter
D. Configure the channel to adjust the tape buffer size with the BLKSIZE option
第4题：
Identify the channel settings that can be performed using the CONFIGURE CHANNEL or ALLOCATE CHANNEL commands in RMAN ？（）
