You run the following query against the dynamic performance view V$ASM_DISKGROUP: SQL> select group_number, name, type, total_mb, free_mb 2 from v$asm diskgroup; GROUP_NUMBER NAME TYPE TOTAL MB FREE MB 1 DATA NORMAL 24568 20798 2 RECOV NORMAL 24568 24090 3 DATA2 HIGH 16376 16221 What can you infer about the disk group DATA2?

Answer: C

Explanation: If the TYPE column is HIGH, then the disk group is mirrored with at least three disks. A is incorrect because if the disk group was mirrored at the operating system level or not at all, the TYPE column would have a value of EXTERN. B is incorrect because TYPE reflects the redundancy level, not performance level. D is incorrect because a value of NORMAL in the TYPE column indicates a redundancy level of two.
