Which of the following statements are true regarding ASM instances and disks? (Choose all that apply.)

Answer: B

Explanation: If you use ASM with RAID disk systems, you will typically turn off the ASM disk group redundancy and let the RAID system handle it; however, using ASM to manage mirroring and load balancing is typically more efficient. In addition, you can mix ASM disk groups with raw disks and datafiles on a file system. A is incorrect because RBAL exists on both the ASM instance and the RDBMS instance. C is incorrect because an ASM disk does not have a database and thus no data dictionary. D is incorrect because ASM instances can only be in the NOMOUNT or MOUNT state.
